Answer:
0.25
Step-by-step explanation:
The fraction is 18/72. The decimal is different. If you divide 72 by 18, you get 4. That tells you how it is in a quarter, aka four pieces. Divide 100 by 4, you get 25. That’s why the answer is 0.25
First cut off for now the rectangle at the top. Ok so now do 75X15 = 1,125. Now we know that's the area if we cut off the top. Now do just the top 10X25=250. Now add 1,125+250= 1,375. is the area

Answer:
10%
0.10
1/10
Step-by-step explanation:
100% = 10/10
when you subtract 9/10 from 10/10 you get 1/10=10%
F(a)=-2a^2 - 5a^4
if a=-3
f(-3)=-2(-3)^2 - 5(-3)^4
=(-2*9) - (5*81)
=-18 - 405
=423
