#1 x÷4=3.5÷28
#2 3/5 + 4/5x +7/10x + 1 1/2 = 5 3/5
Thank you so much guys!!!!!!!!
Answers
Let's start solving #1
x/4 = 3.5/28
Cross multiply
(x)(28) = (3.5)(4)
28x = 14
Divide both sides by 28
28x/28 = 14/28
x = 1/2
Next, let's solve the second one
[tex] \frac{3}{5} + \frac{4}{5x} + \frac{7}{10x} + 1 \frac{1}{2} = 5 \frac{3}{5} [/tex]
Simplifies to:
[tex] \frac{105x+75}{50x} = \frac{28}{5} [/tex]
Cross multiply
(105x + 75)(5) = (28)(50x)
525x + 375 = 1400x
Subtract 1400x to both sides
525x + 375 - 1400x = 1400x - 1400x
-875x + 375 = 0
Then subtract 375 from both sides
-875x + 375 - 375 = 0 - 375
-875x = -375
To find x, divide both sides by -875
-875x/-875 = -375/-875
x = 3/7
Let me know if you have questions about the answer.

Jeff left 13% tip at a restaurant where the bill was $29.62. How much did Jeff leave as a tip?
Answers
Final answer:
To calculate Jeff's tip, multiply 13% as a decimal (0.13) by the bill amount of $29.62, which equals a tip of $3.85.
Explanation:
To calculate how much Jeff left as a tip at the restaurant, we need to find 13% of his bill total, which was $29.62. To do this, convert the percentage to a decimal by dividing by 100 (which makes 13% become 0.13) and multiply that by the bill amount.
So, the calculation will be:
0.13 * $29.62
When you perform this calculation:
$3.85 (rounded to the nearest cent)
Jeff left a $3.85 tip at the restaurant.

Answer: [tex]6\times10^3[/tex] square meters.
Step-by-step explanation:
Given : The soccer field at Mario's school has an area of 6,000 square meters.
Here, 6,000 can be written as [tex]6\times1,000[/tex]
And [tex]1000=10\times10\times10=10^3[/tex] [using exponents]
Then, 6,000 can be written in the form of a whole number multiplied by a power of 10 as [tex]6,000=6\times10^3[/tex]
Hence, Maria can show the area as [tex]6\times10^3[/tex] square meters. .

quartic
quintic
Answers
Quartic is the correct answer.
The solution is Option C.
The equation A = -2x⁴ - x³ + 8x² = 12 is a quartic equation as the degree of the equation is 4
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
-2x⁴ - x³ + 8x² = 12 be equation (1)
On simplifying the equation , we get
Adding 2x⁴ + x³ on both sides of the equation , we get
2x⁴ + x³ + 12 = 8x²
Subtracting 8x² on both sides of the equation , we get
2x⁴ + x³ - 8x² + 12 = 0 be equation (2)
Now , the highest degree of the variable x in the equation is x⁴ which is 4
Therefore , the equation is quartic
Hence , the equation is 2x⁴ + x³ - 8x² + 12 = 0

The point that represents the fraction 3/6 is point B.
Explanation:The point that represents the fraction 3/6 is point B.
When we simplify the fraction 3/6, we obtain 1/2.
To represent a fraction on a number line, we divide the line segment between 0 and 1 into equal parts. Since the denominator is 2, we divide the segment into 2 equal parts. The numerator, 1, represents the number of parts we need to take from the line (starting from 0) to reach the fraction. Thus, we locate point B on the number line to represent the fraction 3/6.

Danielle works as a cashier in a bookstore she works 35 hours a week and earns $11 an hour each week Daniella spends $300 answer saves the rest . Danielle estimates that she earns about $20000 per year is this estimate accurate? explain
Answers
Danielle's estimate of earning about $20,000 per year is accurate, as the calculation based on her hourly wage and weekly hours worked gives an actual annual income of $20,020.
Danielle's estimate of earning about $20,000 per year is accurate based on her hourly wage and weekly hours worked. To assess the accuracy of her estimate, we need to calculate her actual annual income.
Danielle earns $11 per hour and works 35 hours a week. Therefore, her weekly earnings are:
35 hours/week × $11/hour = $385/week.
As there are typically 52 weeks in a year, her estimated annual income would be:
52 weeks/year × $385/week = $20,020/year.
This calculation shows that Danielle's estimate of making about $20,000 per year is indeed accurate.

Jason works at least 5 hours but not more than 10. He earns $15.30 per hour. The function f (t) = 15.3t represents the money he earns for working t hours. What is the practical range? Show all your work.
1. Correctly determine the minimum and maximum money earned.
2. Correctly identify the practical range as inclusive or exclusive.
3. Correctly state the practical range.
Answers
1. The minimum number of hours is 5 hours, so the minimum money earned is:
minimum money = 15.30 * 5 = $76.50
The maximum number of hours is 10 hours, so the maximum money earned is:
maximum money = 15.30 * 10 = $153
2. Since the words “at least” and “not more than” are used, hence this is inclusive.
3. The practical range is:
$76.50 ≤ f(t) ≤ $153
Answer:
$76.50 ≤ f(t) ≤ $153

A water desalination plant can produce 2*10^6 gallons of water in one day. How many gallons can it produce in 79 days?
Write your answer in scientific notation.
Answers
The water desalination plant can produce 1.58 x 10^8 gallons of water in 79 days, expressed in scientific notation.
To calculate how many gallons of water a desalination plant can produce in 79 days, we will multiply the daily production capacity by the number of days. The plant's daily production capacity is given as 2 x 106 gallons. So, for 79 days, the calculation would be:
(2 x 106 gallons/day) x 79 days = 1.58 x 108 gallons
Expressed in scientific notation, the plant can produce 1.58 x 108 gallons of water in 79 days.
What is −412√+75√ in simplest radical form?
Answers
√12 = √4 * √3 = 2√3
√75 = √25*√3 = 5√3
so 4√12 + √75 = 4*2√3 + 5√3 = 13√3 answer
Step-by-step explanation: Given radical expression 4√12 + √75.
Let us simplify each of the radical separately first.
√12 = √(2×2×3) = 2√3
Therefore, 4√12 = 4 × 2√3 = 8√3.
√75 = √(3×5×5) = 5√3
Therefore 4√12 + √75 => 8√3 + 5√3.
Adding like radicals, we get
8√3 + 5√3 = 13√3.
Therefore, 4√12 + √75 = 13√3.PLZ HELP! IN DESPERATE NEED OF HELP! Thx! Remeber to SHOW ALL OF YOUR WORK! Thx so much! :)

in triangle abc,angle a=3x+1,angle b=4x-17,and angle c=5x-20.what type of triangle is angle abc
Answers
12x - 36 = 180
12x = 216
x = 18
angle a = 55
angle b = 55
angle c = 70
This is an acute isosceles triangle.
The sum of the three internal angles in a triangle is equal to 180 degrees.
a = 55°
b = 55°
c = 70°
The triangle abc is an acute isosceles triangle.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three internal angles is equal to 180 degrees.
We have,
Three angles of the triangle:
a = 3x + 1
b = 4x - 17
c = 5x - 20
The sum of the three angles of a triangle is 180 degrees.
a + b + c = 180
3x + 1 + 4x - 17 + 5x - 20 = 180
12x - -36 = 180
12x = 180 + 36
12x = 216
x = 216/12
x = 18
Now,
The angles are :
a = 3 x 18 + 1 = 54 + 1 = 55
b = 4 x 18 - 17 = 72 - 17 = 55
c = 5 x 18 - 20 = 90 - 20 = 70
We see that all their internal angles are acute angles.
This is an acute isosceles triangle.
Thus,
The triangle abc is an acute isosceles triangle.

300/2= $150 per month
^after 2 more months he payed $300^
$150 per months
Equation: (initial amount) - (150)M
M= amount of months after purchase
B = 1800 - 150M
The equation that models the balance b after m months is b = 1800 - 150m
Initial cost = 1800
Difference in balance = 1350 - 1050 = 300
Number of months used = 5 months - 3 months = 2 months
Therefore, the equation that models the balance b after m months will be:
