Answer:
B) 122.5π cm3
Step-by-step explanation:
Volume of a cylinder = 
r= radius , but we are given diameter or 7cm, radius = diameter/2 =7/2 = 3.5cm
h= height, given as 10cm
Next, plug in the numbers into the formula;
Therefore, the volume of soup in the can is 122.5
First you foil so you would get
0.5r+1.375=3
Then you subtract the 1.375 to the 3
0.5r=3-1.375
0.5r=2.375
Now to find r you need to divide by 0.5
r=2.375/0.5
Inv1 investment 1
inv2 investment 2
A) inv1 + inv2 = 33,000
B) .04 inv1 + .07 inv2 = 1,950
Multiplying A) by -.04
A) -.04 inv1 - .04 inv2 = -1,320
Then adding B)
B) .04 inv1 + .07 inv2 = 1,950
.03 inv2 = 630
inv2 = 630 / .03
inv2 = 21,000 invested at 7%
inv1 = 33,000 -21,000=
12,000 invested at 4%
Answer:
300 times
Step-by-step explanation:
600 * 1/2 = 600/2
=300
14:18 is an equivalent ratio!
