Answer:
C
Step-by-step explanation:
When you find the volume for the cone and cylinder they are both 235.62
If you are given $10 every 3.5 hours and you want to find the unit rate per hour, you want to solve for how much money you make every hour. You do this by dividing the $10 by the 3.5 hours, which will result in about $2.86 per hour. (This is a rounded value)
The think the answer for number 7 is A/10
Number 8 is C/16
-2(4w-1)=3(4w+2)
-8w+2=12w+6
-20w=4
w=-0.2
Try x = 65
