V = 4/3 (pi) r^3

ball with radius of 18 cm...
V = 4/3(3.14)(18^3)
V = 4/3(3.14)(5832)
V = 24429.02

ball with radius of 12...
V = 4/3(3.14)(12^3)
V = 4/3(3.14)(1728)
V = 7238.23

24429.02 - 7238.23 = 17190.79 greater <====

30. The perimeter of a rectangle is 292 feet. The length of the rectangle is 4 feet less than 5 times the width. What is the len
trasher [3.6K]
Formula for perimeter ;
P = length + length + width + width 
P = 2l + 2w

l = -4 + 5w
l = 5w - 4

substitute into equation of perimeter 

292 = 2(5w - 4) + 2w

292 = 10w - 8 + 2w

292 + 8 = 10w + 2w 

300 = 12w

25 = w

substitute into eqution to find the length;

l = 5(25) - 4
l = 125 - 4
l = 121

therefore, the width is 25 and the length is 121

hope that helps, God bless!

Jolene invests her savings in two bank accounts, one paying 4 percent and the other paying 10 percent simple interest per year.
Nostrana [21]

Answer:

<h2>$ 22200 in higher yielding bank and $ 44400 in lower yielding bank</h2>

Step-by-step explanation:

       Jolene invests in two bank accounts. The first account gives a 4% interest per year and the second bank gives a 10% interest rate per year.

       She puts twice as much in the lower yielding bank account. Let us denote the amount put in high yielding bank account by x. Lower yielding bank account will have 2x.

       Interest\text{ }per\text{ }year=Principal\times Interest\text{ }rate

Interest from lower yielding bank = \dfrac{4}{100} \times 2x=\dfrac{8x}{100}

Interest from higher yielding bank = \dfrac{10}{100} \times x=\dfrac{10x}{100}

Total Interest per year = $ 3996 = \dfrac{8x}{100} +\dfrac{10x}{100}=\dfrac{18x}{100}

x=22200 \$

∴ Jolene invested $ 22200 in higher yielding bank and $ 44400 in lower yielding bank.
