Answer:
the answer is A. 36
Step-by-step explanation:
because the rectangles are proportionate, I set up ratios.
90:75 so h:30
from there I did 70/30 because those sides are proportionate to each other and this got me 2.5. then I did 90/2.5 to get 36

Divide 2 3/4% by 100% to obtain the fraction 0.0275. This decimal fraction can be reduced to 11/400.
81 + 9 - 9
= 81
81 tan(45)
She is incorrect. The correct answer is 285.74
A= (pi)r^2
Training wheel: A= (3.14)(3)^2=28.26in^2
Wheel: A= (3.14)(10)^2= 314in^2
314-28.26=285.74in^2
9 4/5
5 1/5+4 3/5
26/5+23/5
lcm of the denominator is 5
26+23 everything all over 5
49/5
