Answer:
99.96
Step-by-step explanation:
Your height is correct.
Part B is asking for the length of the hypotenuse.
76.6^2 + 64.25^2 = x^2
x^2 = 9995.6225
x = 99.96 or 99.98 depending on if you round to 76.6 or not
the answer is y=4x-11
use y+1=4x-12
move 1 to negative because move to the other side
so the answer is y=4x-11
Rabbit: y=5x-7
Turtle: y=x
use substitution
x=5x-7
-4x=-7
x=7/4=1.75
1.75hr
7 is the answer, you have to divide 475 by 78 and you get 6.08974358974359 but you round it up to 7 to make sure you have enough buses
