Answer:

The bag contains $5.14

Step-by-step explanation:

18% of 50 = (.18)(50) = 9 pennies

40% of 50 = (.40)(50) = 20 dimes

2 more nickels than pennies = 9 + 2 = 11 nickels

40 coins so far, so 50 - 40 = 10 quarters

Total value:

9 x ($0.01) = $0.09  for pennies

20 x ($0.10) = $2.00 for dimes

11 x ($0.05) = $0.55 for nickels

10 x ($0.25) = $2.50 for quarters

Grand total value = $5.14

Tavius wants to invest $2,500. Which option will earn him the best value?
Step2247 [10]

Tavius would earn his best value if he invests in a  three-year certificate of deposit with a nominal interest rate of 4 percent.

Tavius would invest in the option that yields the highest interest. This is the best value. In order to determine which option is the best, the interest rate of each option has to be determined.

<em><u>Interest rate of the first option</u></em>

Interest earned = amount invested x time x interest rate

$2500 x 0.03 x 2 = $150

<em><u /></em>

<em><u>Interest rate of the second option</u></em>

Interest earned = amount invested x time x interest rate

$2500 x 0.03 x 1 = $75

<em><u /></em>

<em><u>Interest rate of the third option</u></em>

Interest earned = amount invested x time x interest rate

$2500 x 0.04 x 3 = $300

<em><u /></em>

<em><u>Interest rate of the fourth option</u></em>

FV = P x (1 + r) n

$2500 x (1.03) = $75

i am begging for help. all of my points for the first to answer. The volume of a sphere is 3/4 x pi cm^3. what is the radios of
horsena [70]

volume of a sphere = 4/3 *pi * r^3

3/4 * pi = 4/3 *pi * r^3

divide each side by pi

3/4 = 4/3 * r^3

multiply each side by 3/4

3/4 * 3/4 = r^3

9/16 = r^3

take the cube root of each side

r = (9/16) ^ (1/3)
