A rectangle has a perimeter 86 cm and length 36 cm what is its width
Answers
Answer: w = 7cm
Step-by-step explanation:
Perimeter = 2 x length + 2 x width = 2L + 2w
Width is 4 cm less than the length, so w = L-4
36 = 2L + 2(L-4)
36 = 2L + 2L - 8
36 = 4L - 8
44 = 4L
L = 11

Step-by-step explanation:
To find slope, use the following equation
slope (m) = (y₂ - y₁)/(x₂ - x₁)
First, set each coordinate. Let:
(x₁ , y₁) = (-6 , 8)
(x₂ , y₂) = (2 , 3)
Plug in the corresponding numbers for the corresponding variables.
m = (y₂ - y₁)/(x₂ - x₁)
m = (3 - 8)/(2 - (-6))

If you want to know when their cost will be the same, set the equations equal to each other.
5.25x + 25 = 4.50x + 35
0.75x + 25 = 35 subtracted 4.50x from both sides
0.75x = 10 subtracted 25 from both sides

=>11/36 - 7/36
=>4/36

Answer:
it is 5 36
heres why
Step-by-step explanation:
Here's how to subtract 7/9 from 11/12:
11
12
−
7
9
Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 11 by 9, and get 99.
Then we multiply 7 by 12, and get 84.
Next we give both terms new denominators -- 12 × 9 = 108.
So now our fractions look like this:
99
108
−
84
108
Step 2
Since our denominators match, we can subtract the numerators.
99 − 84 = 15
So the answer is:
15
108
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Nope! So now we try the next greatest prime number, 3...
Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:
15
108
÷ 3 =
5
36
Let's try dividing by 3 again...
Nope! So now we try the next greatest prime number, 5...
Nope! So now we try the next greatest prime number, 7...
No good. 7 is larger than 5. So we're done reducing.
There you have it! The final answer is:
11

describe the difference between parallel and perpendicular lines, their slopes and graphs
Answers
Parallel lines have the same slopes (but different y intercepts). Parallel lines never cross. Parallel lines are the same distance from each other no matter where you are on either line. Think of it like a pair of perfectly straight railroad tracks.
-------------------------------------------------------------------------------------
Perpendicular lines cross at one point. The two lines form a 90 degree angle. The two slopes multiply to -1, which is another way of saying that the slopes are negative reciprocals of one another. For example, a line with a slope of 2/3 and another line with a slope of -3/2 has these two values multiply to -1; therefore showing they are perpendicular lines.
To provide a short definition,
Parallel lines are lines as the word suggests "parallel" which means they will stay side by side and never cross.
Perpendicular lines are lines that cross, usually to determine perpendicular lines you would take a slope and negatively reciprocate it.
Perpendicular:
1/2 -> -2
Parallel:

A model for a company's revenue from selling a software package is R(p) = -2.5p² + 500p, where p is the price in dollars of the software. What price will maximize revenue? Find the maximum revenue.
The price $_____ maximizes the revenue.
The maximum revenue is $_____.
Answers
Answer: p = $100, R = $25,000
Step-by-step explanation:
The maximum is the y-value of the Vertex.
Step 1: Use the Axis-Of-Symmetry (AOS) formula to find x: [tex]x=\dfrac{-b}{2a}[/tex]
R(p) = -2.5p² + 500p
a=-2.5 b=500
[tex]p=\dfrac{-(500)}{2(-2.5)}[/tex]
[tex]=\dfrac{-500}{-5}[/tex]
[tex]=100[/tex]
Step 2: Find the maximum by plugging the p-value (above) into the given equation.
R(100) = -2.5(100)² + 500(100)
= -25,000 + 50,000
= 25,000
The price that maximizes revenue for the software package is $100, and the maximum revenue attainable is $25,000 based on the given revenue function R(p).
To find the price that maximizes revenue and the maximum revenue itself, we can use the given revenue function R(p) = -2.5p² + 500p.
To find the price that maximizes revenue, we need to find the vertex of the quadratic function, as the vertex represents the maximum point. The formula for the x-coordinate (price in this case) of the vertex of a quadratic function in the form of ax² + bx + c is given by:
x_vertex = -b / (2a)
In our case, a = -2.5 and b = 500:
x_vertex = -500 / (2 * (-2.5))
x_vertex = -500 / (-5)
x_vertex = 100
So, the price that maximizes revenue is $100.
To find the maximum revenue, we need to substitute this price back into the revenue function:
R(100) = -2.5(100)² + 500(100)
R(100) = -2.5 * 10000 + 50000
R(100) = -25000 + 50000
R(100) = 25000
Therefore, the maximum revenue is $25,000.
So, the price that maximizes revenue is $100, and the maximum revenue is $25,000.

7. The two small triangles in the following are similar. Find the value of x to the nearest thousandth. (See attached image.)
A) x=32, y=25.6
B) x=12, y=15
C) x=9.6, y=12
D) x=15, y=12
E) None of the above.
Answers
So to find x you must first find y which can be done simply by using the pythagorean theorem. This theorem is defined as the sum of the squared legs is equal to the sum of the hypotenuse or x^2 + y^2 = z^2
If we substitute in the known values 16^2 + y^2 = 20^2 and solve for y we get that y = sqrt(20^2 - 16^2), this then simplifies to y = 12
Finding x is much more annoying, the easiest way I can immediately see is to find the upper angles by doing sin(16/20) and then 90 - sin(16/20) since the complementary angle is the one you want. I don't have a calculator or a trig table with me right now but I will tell you that x will be equal to 12 ÷ the inverse cosine of the angle (90degrees - sin(16/20)).
I am pretty sure the answer is D though because we know for sure y = 12 and x has to be greater than y because the hypotenuse must be larger than both legs. It could be E but you won't know unless you do the math for x. So it is either D or E but I would be surprised if a Professor made you do all of the work just to say it doesn't work...

What are the zeros of the quadratic function? f(z)=3z^2−11z−4 Enter your answers, as simplified fractions if necessary, in the boxes.
Answers
Answer:
z=4 and z=-1/3 are the zero's
Step-by-step explanation:
To find the zeros of the quadratic function, we need to set it equal to zero.
f(z)=3z^2−11z−4
0 =3z^2−11z−4
Now we need to factor the function
0 = (z - 4) (3 z + 1)
Then using the zero product property set each factor to zero
0 = z-4 0 = 3z+1
Now solve
0+4 = z-4+4 0 -1 = 3z+1-1
4 =z -1 = 3z
-1/3 = 3z/3
-1/3 =z

Q = a b^t = a (1+r)^t
Comparing with the formulas:
a=79
b=1.002

Answer: A) 628 miles
The question uses geometry and the concept of arc length to ask the distance between Seattle and San Francisco on the Earth's surface. The distance between the two cities is calculated to be 628 miles.
Explanation:This is a mathematics problem using geometry, specifically related to the calculation of the arc length. The difference in latitudes between Seattle and San Francisco gives us the angle measurement on the sphere's surface. The difference is 47° - 38° = 9°. Since 9° is 1/40th of a full circle (360°), the arc is 1/40th of the total circumference.
So, to find the distance between the two cities, we calculate 1/40th of the circumference of the Earth (which is 2πr) by using the given radius of the Earth (4,000 miles). The calculation is 1/40 * 2 * 3.14 * 4000 = 628 miles. So, The distance between Seattle and San Francisco via the arc length on the sphere's surface is approximately 628 miles.
Therefore, the correct answer is A) 628 miles.
