PLEASE HELP ASAP!!! 7th Grade Math.​

Mathematics
1 answer:
Otrada [13]4 years ago
7 0

Answer:

1,300

Step-by-step explanation:

First, we need to substitute all the variable with the given number.

To figure out the 2 equivalent squares, do 20 x 20 , which is 400.

Then, the 3rd triangle, do 28 x 25 , equaling 700.

Lastly, for the 2 triangles, 20 x 20 / 2 , leading to the solution of 200.

Now, putting everything together by adding 400+700+200, the final answer is 1,300.

I hope this helped!!

Trevon is making payments on a car that costs $26,555. He makes 36 equal payments.If he rounds the equal payments up to the near
scoundrel [369]

Trevon will overpay around $13

Further explanation:

One time payment will be calculated by dividing the total amount by 36 and then the answer will be rounded off to nearest dollar

So,

Given

Cost\ of\ car=\ 26555\\Number\ of\ payments=36\\Amount\ of\ one\ payment = \frac{26555}{36}\\=737.64

One time payment is 737.64. Rounding off to nearest dollar gives us 738.

If 738 is paid 36 times,

Total\ amount\ paid=36*738=26568

The amount that will be overpaid is:

=26568-26555=13

Trevon will overpay around $13

The area of a circle of radius 10 units is equal to the surface area of a sphere of radius 5 units.
Hoochie [10]
<h3>Answer:  True</h3>

Explanation:

The area of the circle with radius 10 is...

A = pi*r^2

A = pi*10^2

A = 100pi

The surface area of the sphere with radius 5 is...

SA = 4pi*r^2

SA = 4pi*5^2

SA = 100pi

Both results are the same, so the claim is true. We can think of surface area as the amount of wrapping paper needed to cover the sphere.

Find the slope of the line. On a coordinate plane, a line goes through (0, negative 6) and (2, 0). a. Negative one-third c. 3 b.
statuscvo [17]

The slope of the line that passes through between (0, -6) and (2, 0) is: C. 3.

<h3>What is the Slope of a Line?</h3>

The slope of a line can be defined as the measure of the ratio of the vertical distance to the horizontal distance that exists between two points on a coordinate plane.

<h3>How to Find the Slope of a Line?</h3>

If we are given two points on a line, (x1, y1) and (x2, y2), the slope (m) is the rise/run = change in y / change in x = (y2 - y1)/(x2 - x1).

Given the following coordinates of two points as follows, (0, -6) and (2, 0), let:

(0, -6) = (x1, y1)

(2, 0) = (x2, y2)

Plug in the values into the slope formula to find the slope:

Slope (m) = (0 - (-6)) / (2 - 0)

Slope (m) = (0 + 6) / (2 - 0) [minus multiplied by minus is plus]

Slope (m) = (6) / (2)

Slope (m) = 3

Thus, the slope of the line that passes through between (0, negative 6) and (2, 0) is calculated as: C. 3.

Write the following in interval notation:
elena-14-01-66 [18.8K]

Answer:

10/13 ≤ x < 18/13

Step-by-step explanation:

-1 ≤ 13x - 11 < 7

If a ≤ u < b then a ≤ u and u < b

⇒ -1 ≤ 13x - 11  and  13x - 11 < 7

-1 ≤ 13x - 11

Add 11 to both sides:  10 ≤ 13x

Divide both sides by 13:  10/13 ≤ x

13x - 11 < 7

Add 11 to both sides:  13x < 18

Divide both sides by 13:  x < 18/13

Combine the intervals

10/13 ≤ x < 18/13
