V=(4/3)pir^2
c=2pir
12=2pir
divide 2
6=pir
divide by pi
6/pi=r
sub for r
V=(4/3)pi(6/pi)^2
V=(4/3)pi(36/(pi^2))
V=(4/3)(36/pi)
V=144/(3pi)
V=48/pi
aprox pi=3.141592
V=15.2788777155
V=15.28 in^3
(10 - 5 2/3) * -2 + x = 8 2/3
(9 3/3 - 5 2/3) * -2 + x = 8 2/3
4 1/3 * -2 + x = 26/3
13/3 * -2 + x = 26/3
-26/3 + x = 26/3
x = 26/3 + 26/3
x = 52/3 or 17 1/3 <==
Answer
$6000
Step-by-step explanation:
Using the formulas
PLAN A
y = .09x + 350
PLAN B
y = .03 + 704
He makes $890 on plan A and only $884 on plan B
For the pears, Betty will need 13 jars. I know this because I divided 104 by 8. I did the same for the apples. 126 divided by 6. You get 21. Have a nice day!
