Answer:
96π^2 = 947.48
Step-by-step explanation:
π × r² × h
8π times 3*4*π
Step 1:
Add rent & car payments
=11,250+1422
=$12,672
Step 2:
to determine %, set up a proportion
12,672 is to his total of 39,600 as x is to 100
12,672/39,600 = x/100
cross multiply
(12,672)(100) = (39,600)(x)
1,267,200= 39,600x
divide both sides by 39,600
32%= x
OR
Alternative Step 2:
12,672 ÷ 39,600= 0.32
Alternative Step 3:
0.32 x 100 = 32%
or move decimal to the right 2 places
His rent and car payments are 32% of his earnings.
Hope this helps! :)
Answer:
uhh, look it up
Step-by-step explanation:
15.
if he ordered the same amount each month (x) and it is a whole number,
then
12*x=6150, and
x =6150/12 should be a whole number
x=512.5
so 512.5 is not a whole number and the produce company does not agree
16.
16410/138≈118.91
because it not a whole number, she sells pieces for different prices
