Using the formula, solve for c, if a = 9 and b = 40 a² + b2 = c²
A C = 7
B. C = -25
C. c = 41
D. c= /49

Step-by-step explanation:

c² = a² + b²

a = 9 , b = 40

Substitute the values of a and b into the equation and solve

That's

We have the final answer as

Hope this helps you

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

he has now walked a total of what?

if i know what this is maybe i can
