We have been given the length of the ramp on the blueprint is 7.6 inches. The scale on the blueprint is 1 inch to 4 feet. We are asked to find the actual length of the ramp.

We will use proportions to solve our given problem as:

$\frac{\text{Actual length}}{\text{Scale length}}=\frac{4\text{ ft}}{1\text{ inch}}$

Now, we will substitute the scale length of ramp in our proportion as:

$\frac{\text{Actual length}}{7.6 \text{ Inches}}=\frac{4\text{ ft}}{1\text{ inch}}$

$\frac{\text{Actual length}}{7.6 \text{ Inches}}\cdot 7.6 \text{ Inches}=\frac{4\text{ ft}}{1\text{ inch}}\cdot 7.6 \text{ Inches}$

$\text{Actual length}=4\text{ ft}\cdot 7.6$

$\text{Actual length}=30.4\text{ ft}$

Therefore, the actual length of the ramp would be 30.4 feet.

PYTHAGOREAN THEOREM

Sav [38]

Answer:

the answer is 29

Step-by-step explanation:

a^2 + b^2 = c^2 (btw ^ means to the power)

a and b are the legs. c is the hypotenuse

21^2 + 20^2 = c^2

441 + 400 = 481

then we have to square it.

the square root of 481= 29.

btw the hypotenuse is always going to be bigger than the legs.

hope it helps!! btw it is right!
