Answer:

$307.5.

Step-by-step explanation:

We have been given that Elena's aunt bought her a $150 savings bond when she was born.When Elena is 20 years old, the bond will have earned 105% in interest.  

To find bond's value after 20 years we will add 105% of 150 to 150.

\text{Bond's value after 20 years}=150+(\frac{105}{100}\times 150)

\text{Bond's value after 20 years}=150+(1.05\times 150)

\text{Bond's value after 20 years}=150+157.5

\text{Bond's value after 20 years}=307.5

Therefore, the bond will be worth $307.5, when Elena will be 20 years old.

The volume of a cylindrical water tank is 2783π cubic feet. If the radius is 11 feet, what is the height of the tank?
jolli1 [7]

Answer:

23 feet

Step-by-step explanation:

Givens

Volume = pi r^2 h

r = 11

V = 2783 pi

Solution

2783 pi = pi 11^2 * h            Cancel the 2 pi's

2783 = 11^2 h                       Expand 11^2

2783 = 121 * h                       Divide by 121

2783/121 = h

h = 23 feet
