Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $13 monthly fee and charges an additional $0.17 for each minute of calls. The second plan has a $23 monthly fee and charges an additional $0.13 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
To find the number of minutes at which the costs of the two plans will be equal, we set up an equation and solve for x. The costs will be equal after 250 minutes of calls.
Explanation:To find the number of minutes of calls at which the costs of the two plans will be equal, we can set up an equation. Let's denote the number of minutes as x. For the first plan, the total cost is given by:
Total Cost = $13 + $0.17x.
For the second plan, the total cost is given by:
Total Cost = $23 + $0.13x.
Setting these two equations equal to each other, we have:
$13 + $0.17x = $23 + $0.13x.
Simplifying this equation, we get:
$0.17x - $0.13x = $23 - $13.
$0.04x = $10.
Dividing both sides by $0.04, we get:
x = $10/$0.04 = 250 minutes.
Therefore, the costs of the two plans will be equal after 250 minutes of calls.

Which function has the same range as
Answer: Second Option
[tex]g(x)=-\frac{5}{7}(\frac{3}{5})^{-x}[/tex]
Step-by-step explanation:
The function [tex]g(x)=(\frac{3}{5})^x[/tex] is an exponential function.
Functions of this type have a range that goes from (0, ∞)
When multiplying the function by a negative coefficient [tex]-\frac{5}{7}[/tex], now all the values of g(x) will be negative and the range of [tex]g(x)=-\frac{5}{7}(\frac{3}{5})^x[/tex] will be: (-∞, 0)
Then we must search among the options a function with range (-∞, 0)
Since the exponential functions of the form [tex](a) ^ x[/tex], where [tex]a>0[/tex] always have range (0, ∞) Then the correct option will be the one with a negative coefficient.
The correct option is the second option
The function [tex]h(x) = -\frac{5}{7}\cdot \left(\frac{3}{5} \right)^{-x}[/tex]same range of [tex]f(x) = - \frac{5}{7}\cdot \left(\frac{3}{5} \right)^{x}[/tex].
How to determine the range of another function based on transformationsIn this question we must determine a second function whose range is equal to the range of the first one. In geometry, a rigid transformation is a transformation experimented by a function such that euclidean distance is conserved. The range is the set of values of [tex]h(x)[/tex] associated to the function.
If we apply a reflection around the y-axis, then the range is conserved but relationship between the range and the domain is changed in rigid manner. The reflection around the y-axis follows the following formula:
[tex]h(x) = f(-x)[/tex] (1)
If we know that [tex]f(x) = - \frac{5}{7}\cdot \left(\frac{3}{5} \right)^{x}[/tex], then the resulting function is:
[tex]h(x) = -\frac{5}{7}\cdot \left(\frac{3}{5} \right)^{-x}[/tex]
The function [tex]h(x) = -\frac{5}{7}\cdot \left(\frac{3}{5} \right)^{-x}[/tex] has the same range of [tex]f(x) = - \frac{5}{7}\cdot \left(\frac{3}{5} \right)^{x}[/tex]. [tex]\blacksquare[/tex]

Find the surface area of the composite solid.
Answer:
Option B is correct.
Step-by-step explanation:
Given:
A Solid Figure made up pf cuboid and a triangular based prism.
To find: Total Surface area of the figure.
Total Surface Area = Area of front + Area of top + Area of Back + 2 × Area of side + Area of bottom
Area of Front = Area of Square + Area of rectangle
= 10 × 10
= 100 in.²
Area of top = Area of Rectangle
= 13 × 10
= 130 in.²
Area of back = Area of square in down + Area of rectangle in up
= 10 × 10 + 5 × 10
= 100 + 50
= 150 in.²
Area of the bottom = Area of the rectangle
= 12 × 10
= 120 in.²
Area of the side = Area of rectangle + Area of the triangle
= 12 × 10 + 1/2 × 5 × 12
= 120 + 5 × 6
= 120 + 30
= 150 in.²
Total Surface Area = 100 + 130 +150 + 120 + 2 × 150
= 500 + 300
= 800 in.²
Therefore, Option B is correct.

Julius bought a total of 2 gallons of beverages, including 2 quarts of orange juice and 16 cups of chocolate milk.
To find out how many gallons of beverages Julius bought, we need to convert each quantity to gallons and then sum them up:
1. **2 pints of milk**:
- 1 pint = 0.125 gallons
- 2 pints = [tex]\(2 \times 0.125 = 0.25\)[/tex] gallons
2. **2 quarts of orange juice**:
- 1 quart = 0.25 gallons
- 2 quarts = [tex]\(2 \times 0.25 = 0.5\)[/tex] gallons
3. **16 cups of chocolate milk**:
- 1 cup = 0.0625 gallons
- 16 cups =[tex]\(16 \times 0.0625 = 1\)[/tex] gallon
4. **32 ounces of lemonade**:
- 1 ounce = 0.0078125 gallons
- 32 ounces = [tex]\(32 \times 0.0078125 = 0.25\)[/tex] gallons
Now, let's sum up the quantities:
[tex]\[ 0.25 + 0.5 + 1 + 0.25 = 2 \][/tex]

A rectangular prism is 3 units high 2 units wide and 5 units long what is its surface area in square units
Answer:
62 square units
Step-by-step explanation:
The area of a rectangular prism is the sum of the areas of its six faces. Opposite faces have the same area, so it is the sum of 3 pairs of faces. The area of one face of each pair is the product of the dimensions of that face. Those three areas are ...
• L·W
• W·H
• H·L
so the total surface area is ...
A = 2(LW +WH +HL)
For hand calculation, this can be simplified a bit to ...
A = 2(LW +H(L+W)) . . . . . requires one less multiplication
For your prism, the area is ...
A = 2(5·2 + 3(5+2)) = 2(10 +21) = 62 . . . square units
A rectangular prism is a three-dimensional shape with six faces. The opposite faces are equal in length. It has twelve sides and six vertices
The formula for the surface area of a rectangular prism = SA=2lw+2lh+2hw
Where:
l = length
w = width
h = height
Surface area = (2 x 5 x 2) + (2 x 5 x 3) + (2 x 3 x 2)
= 20 + 30 + 12
= 62 square units

Please help me find the area of the triangular prism. and show the work please
Answer: 36 in²
Step-by-step explanation:
You can calculate the area of this right prism by adding the area of its faces.
You can observe that the faces of the right prism are: Three different rectangles and two equal triangles.
The formula for calculate the area of a rectangle is:
[tex]A=lw[/tex]
Where "l" is the lenght and "w" is the width.
The formula for calculate the area of a triangle is:
[tex]A=\frac{bh}{2}[/tex]
Where "b" is the base and "h" is the height.
You can observe that the hypotenuse of the each triangle is the length of the larger rectangle, then , you can find its value with the Pythagorean Theorem:
[tex]a=\sqrt{b^2+c^2}[/tex]
Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.
Then, this is:
[tex]a=\sqrt{(4in)^2+(3in)^2}=5in[/tex]
Therefore, you can add the areas of the faces to find the area of the right prism (Since the triangles are equal, you can multiply the area of one of them by 2). This is:
[tex]A=(2in)(5in)+(3in)(2in)+(4in)(2in)+2(\frac{3in*4in}{2})=36in^2[/tex]
What is the y-coordinate of the point of intersection for the two lines given below?
A: 4
B: -14
C: -3
D: -2
Answer:
B. -14
Step-by-step explanation:
If you solve the system using the method of elimination, the y terms will automatically cancel each other out without any manipulation at all. So go with it and solve for x first. If the y terms cancel out, you're left with x = -3.
If x = -3, sub that value in for x in eitheer one of the original equations and solve for y:
[tex]3x-y=5[/tex] becomes
[tex]3(-3)-y=5[/tex] and
[tex]-9-y=5[/tex] so

The sum of three numbers is 69. If the second number is equal to the first diminished by 8, and the third number is 5 times the first. What are the numbers?The sum of three numbers is 69. If the second number is equal to the first diminished by 8, and the third number is 5 times the first. What are the numbers?The sum of three numbers is 69. If the second number is equal to the first diminished by 8, and the third number is 5 times the first. What are the numbers?
Answer:
They are 3, 11 and 55.
Step-by-step explanation:
x +y + z = 69
y = x - 8
z = 5x
Substitute z = 5x in the first equation:
x + y + 5x = 69
6x + y = 69.........(1)
From the second equation
-x + y = -8.........(2)
Subtract equations (1) - (2):
7x = 77
x = 11
So z = 5x = 5*11 = 55 and
y = x - 8 = 11 - 8 = 3..
Answer:
x = 11, y = 3 and z = 55
Step-by-step explanation:
Let the three numbers be x, y and z. Then x + y + z = 69
Then y = x - 8, and z = 5x. Substituting these expressions in x into
x + y + z = 69, we get: x + x - 8 + 5x = 69, or
7x = 77, so that x = 11.
If x = 11, then:
y = x - 8 = 11 - 8 = 3, and:
z = 5x = 5(11) = 55
Then x = 11, y = 3 and z = 55.
Check: Do these three numbers add up to 69? 11 + 3 + 55 = 69? YES

What is the y-value of the vertex of the function f(x) = –(x – 3)(x + 11)?
The y-value of the vertex is
.
Answer:
49
Step-by-step explanation:
Given
f(x) = - (x - 3)(x + 11)
Find the zeros by setting f(x) = 0, that is
- (x - 3)(x + 11) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x + 11 = 0 ⇒ x = - 11
The vertex lies on the axis of symmetry which is situated at the midpoint of the zeros
[tex]x_{vertex}[/tex] = [tex]\frac{3-11}{2}[/tex] = [tex]\frac{-8}{2}[/tex] = - 4
Substitute x = - 4 into f(x) for y- coordinate of vertex
f(- 4) = -(- 7)(7) = 49 ← y- value of vertex

The Earth completely rotates on its axis once every 24 hours.
A) How long does it take for it to rotate 225 degrees?
B) How long does it take to rotate 9π radians?
C) The diameter of the Earth is approximately 7920 miles. How far will a point on the equator rotate in 2 hours?
Show all work. Give answers to the nearest hundredth. Include the units in your response.
Answer:
A) 15 hours
B) 108 hours
C) 2073.45 miles
Step-by-step explanation:
The earth rotates fully 1 time in 24 hours. Fully rotate means that it goes through 360 degrees in 24 hours.
A)
For this, we can set up unit ratio to solve.
"If earth rotates 360 degrees in 24 hours, 225 degrees take how much time (let it be x)?"
[tex]\frac{360}{24}=\frac{225}{x}\\360x=24*225\\360x=5400\\x=\frac{5400}{360}\\x=15[/tex]
So , it takes 15 hours.
B)
Here, the rotation is given in radian, NOT degrees. We know that 2π radians is 360 degrees, thus we can say:
"If earth rotates 2π radians in 24 hours, 9π radians take how much time (let it be y)?"
[tex]\frac{2\pi}{24}=\frac{9\pi}{y}\\2\pi y=9\pi * 24\\2\pi y = 216\pi\\y=\frac{216\pi}{2\pi}\\y=108[/tex]
So, it take 108 hours.
C)
The point on the equator is on the "outside" of the earth. So we need to figure out the circumference of the earth, given diameter is approximately 7920.
Circumference formula is C = 2πr, where C is the circumference, r is the radius (half of diameter, which is 7920/2 = 3960)
Hence
C = 2πr = 2π(3960) = 7920π
Hence, is 24 hours, a point travels 7920π miles. 2 hours is 1/12th of 24 hours, so in 2 hours the point will travel 1/12th the distance is travels in 24 hours. So:
[tex]\frac{7920\pi}{12}=2073.45[/tex]
Thus, it will travel 2073.45 miles in 2 hours.
Answer:
A). 15 hours
B). 108 hours
C). 2074.28 miles
Step-by-step explanation:
A). The Earth completely rotates on its axis once every 24 hours.
It means the Earth takes 24 hours to complete 360° or 2π radians
Per hour rotation of the Earth will be = [tex]\frac{\text{Angle rotated in one rotation}}{\text{Time taken for one rotation}}[/tex]
= [tex]\frac{360}{24}=15[/tex] degree per hour
or [tex]\frac{2\pi }{24}=\frac{\pi }{12}[/tex] radians per hour
Now we have to calculate the time taken in 225° rotation.
∵ In 15° rotation was time taken = 1 hour
∴ In 1° rotation time taken by the Earth = [tex]\frac{1}{15}[/tex]
∴ In 225° time spent by the Earth = [tex]\frac{(1)(225)}{15}=15[/tex] hours
B). ∵ [tex]\frac{\pi }{12}[/tex] radians rotation was completed in the time = 1 hour
∴ 1 radian rotation was completed in time = [tex]\frac{1}{\frac{\pi }{12}}=\frac{12}{\pi }[/tex]
∴ 9π radians rotation will be completed in time = [tex]\frac{12(9\pi )}{\pi }= 108[/tex] hours
Therefore, time taken in 9π rotation will be 108 hours.
C). If the diameter of the earth is 7920 miles then we have to calculate angle of rotation of a point on equator in 2 hours.
Since Length of arc = radius × angle of rotation
Since angle of rotation in 1 hour = [tex]\frac{\pi }{12}[/tex] radians
So angle of rotation in 2 hours = [tex]\frac{2\pi }{12}=\frac{\pi }{6}[/tex]
Now we put these values in the formula
Length of arc = [tex]\frac{7920}{2}(\frac{\pi }{6})=660\pi[/tex] miles
= 660(3.1428)
= 2074.28 miles

width of the base. The length of the base is twice the width.
Which expression represents the volume of the prism in
terms of w, the width of the base?
6 II
O5w2 cubic units
O6w2 cubic units
O 5w cubic units
O6wº cubic units
Answer:
6w³ cubic units
Step-by-step explanation:
The volume of a right rectangular prism is the product of its dimensions:
V = LWH
= (2w)(w)(3w) = 6w³ . . . . cubic units
Answer:
6*W^3 cubic units
Step-by-step explanation:
Right rectangular prism volume (V) is calculated as
V = L*W*H
where L is length, W is width and H is height
The height is three times the width of the base means
H = 3*W
The length of the base is twice the width means
L = 2*W
Replacing in volume formula
V = 2*W*W*3W
V = 6*W^3
A vegetable and a surrounding path are shaped like a square that together are 11 ft wide. The path is 2 feet wide. If one bag of gravel covers 9 square feet, how many bags are needed to cover the path?
Answer:
8 bags
Step-by-step explanation:
The area of the path is equal to the area of the overall square minus the area of the garden.
Area of a square is the side length squared:
A = s²
The overall square has a side length of 11 feet. The side length of the garden is 11 - 2 - 2 = 7 feet. So the area of the path is:
A = 11² - 7²
A = 121 - 49
A = 72
The area of the path is 72 ft². If one bag of gravel covers 9 ft², then the number of bags needed is:
72 ft² × (1 bag / 9 ft²) = 8 bags
When Frank buys three packs of pens, he knows he has 36 pens. When he buys five packs, he knows he has 60 pens. What is the constant of proportionality between the number of packs and the number of pens?
Answer:
The answer is 12. There are 12 pens in each pack.
Step-by-step explanation:
The constant of proportionality between the number of packs and the number of pens that Frank buys is 12 pens per pack, calculated by dividing the total pens by the number of packs in both given scenarios.
The student asks about the constant of proportionality between the number of packs of pens and the number of pens. To find this, we divide the number of pens by the number of packs for each given scenario to ensure the ratio is consistent.
Given Frank buys three packs and ends up with 36 pens, we divide 36 pens by 3 packs to get 12 pens per pack.
When he buys five packs and has 60 pens, we again divide 60 pens by 5 packs and get the same result, 12 pens per pack. Therefore, the constant of proportionality is 12 pens per pack.

Construct a triangle with interior angle measures of 60° and 60°. Let one of the side lengths be 10. What are the lengths of the other sides?
Answer:
The lengths of the other sides is equal to 10 units
Step-by-step explanation:
we know that
An equilateral triangle is a triangle that have three equal sides and three equal interior angles (each internal angle measure 60 degrees)
so
If the triangle has two interior angle measures of 60° and 60°, then the measure of the third interior angle must be equal to 60 degrees (remember that the sum of the interior angles in a triangle must be equal to 180 degrees)
Therefore
The triangle is an equilateral triangle and the length of the three sides is equal to 10 units

(1 pt) What is the reciprocal of the number ? -3/5 A. -1 2/3 B. -1 3/5 C. 3/5 D.1 2/3
Reciprocal means to flip it, so in this case swap the numerator and denominator and the answer will be:
[tex] - \frac{5}{3} \: \: or \: \: - 1 \frac{2}{3} [/tex]
I would choose A
How do you find the mode of a set of numbers
Answer:
The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list.
Step-by-step explanation:
Two years after it’s purchase, if Manuel’s gift card is unused, the automatic decrease on the gift card balance is given by the equation b = 50 - 5m, where m is the number of months beyond two years.
Is this model of the siu action linear? If it is, what are the slope and y-intercept?
A. linear: slope = -10, y-intercept = 5
B. linear: slope = -50, y-intercept = 5
C. linear: slope = -5, y-intercept = 50
D. not linear
Answer:
Option C. linear: slope = -5, y-intercept = 50
Step-by-step explanation:
Let
b ----> is the automatic decrease on the gift card balance
m ----> is the number of months beyond two years
we know that
The equation of the line into slope intercept form is equal to
[tex]y=mx+b[/tex]
where
m is the slope
b is the y-intercept
In this problem the linear equation that represent this situation is
[tex]b=-5m+50[/tex] ---> equation of the line into slope intercept form
so
The slope is -5
The y-intercept is 50
Answer:
This function is linear. True
The slope of this function is 50. False
The y-intercept of this function is 50. True
A motorboat takes 5 hours to travel 500 km up stream the return trip takes 4 hours going down stream. What is the rate of the boat in still water? And what is the rate of the current
Answer: 25 km
Step-by-step explanation:
500 km / 5 = 100 km up stream
500 km / 4 = 125 km down stream
125 - 100 = 25 km in still water
