I got that r, the regular price of the monthly fee is 62.
So first I started with the equation;
392.50 = 10( \frac{1}{2} r+ 8.25)
then I divided both sides by 10 which then gave me;
39.25 =  \frac{1}{2} r + 8.25
after that, I subtracted 8.25 from both sides;
31 =  \frac{1}{2} r
then I multiplied by 2 to get R alone and that's how I got 62

(12 x 2) - 5 because twice as many means to multiply by 2. fewer means to subtract.

Round to the nearest tenth wa hit is the perimeter of the triangle
klio [65]

Answer:

D. 11.8 cm

Step-by-step explanation:

This triangle is a 30°-60°-90° triangle. There is a shortcut to find the lengths of the sides of a 30°-60°-90° triangle. The longest side is the hypotenuse. The longest side is double the shortest side or, the shortest side is half the longest side. Here the longest side is 5, so the short leg (shortest side) is 2.5

The other shortcut is that the longer leg is the

short leg×sqroot3

Here, the short leg is 2.5, so the long leg is 2.5×sqroot3

Perimeter is all the sides added together.

5 + 2.5+ 2.5×sqrt3

Do the times first.

5 + 2.5 + 4.3

= 11.8

A ladder is leaning against
Svetradugi [14.3K]

Answer:

25 ft

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

15^2 + 20 ^2 = x^2

225+400= x^2

625 = x^2

Take the square root of each side

sqrt(625) = sqrt(x^2)

25 = x
