Answer: 17.5%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 7/40 as a percent, we need to find a fraction equivalent to 7/40 that has a 100 in the denominator.
We can do this by setting up a proportion.
![\frac{7}{40} = \frac{n}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B40%7D%20%3D%20%5Cfrac%7Bn%7D%7B100%7D)
Now we can use cross products to find the missing value.
=
![40n.](https://tex.z-dn.net/?f=40n.)
700 = 40n
Next, dividing both sides of the equation by 40, we have <em>17.5 = n</em>.
So, 7/40 is equal to 17.5/100 or 17.5%.
![\frac{20}{2(5+5)}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B2%285%2B5%29%7D)
- Following the order of operations, we do parenthesis first.
![\frac{20}{2(10)}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B2%2810%29%7D)
- Multiply out the value against the parenthesis.
![\frac{20}{20} = 1](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B20%7D%20%3D%201)
- This leaves us with 20 over 20. 20 goes into 20 only 1 time, so our final answer is 1.

i did my math i hope it helps good luck
The distance between any two points is the <em>absolute value of their difference</em>. Only one of those expressions provided represents the difference between -7 and 16; the others alter the numbers in one way or another. Which one of those absolute value expressions contains the <em>difference of -7 and 16</em>?
Perpendicular = 15cm
Base = 36cm
Let Hypotenuse = X
By using Pythagoras theorem
15^2 + 36^2 = x^2
x^2 = 1296
x = ± 39
since length cannot be negative Length of missing side = 39
