Answer:

1. 96%

2. $6000

3. 176

4. 20%

Step-by-step explanation:

1. 1/5 of 80% is 16%. 80+16=96

2. 25% of 8000 is 2000. 8000-2000= 6000.

3. 10% increase of 200 is 20. 20+200=220. 20 percent of 220 is 44. 220-44=176

4. if you increase the original salary by 20%, then decreasing it by 20% of the new salary will give you the old salary.

A bowl is in the shape of a hemisphere (half a sphere) with a diameter of 8 inches. Find the volume of the bowl. Use 3.14 for pi
gayaneshka [121]

Answer: 267.947 (or 267.95) inches^3

Step-by-step explanation:

The formula for the volume of a sphere is \frac{4}{3}\pi r^{3}.

To find your radius (r), divide the diameter of 8 inches by 2. <em>The radius is 4 inches.</em>

Plug in your numbers to the volume equation to get \frac{4}{3} (3.14)(4^3). The first step is to cube 4 (4*4*4) to get <em>64</em>. Now your equation is \frac{4}{3}(3.14)(64).

Multiply 3.14 and 64 to get <em>200.96</em>. The equation is now \frac{4}{3}(200.96) or \frac{4}{3} * \frac{200.96}{1}.

Multiply the numerators (4 * 200.96) and denominators (1 * 3) to get a final equation of \frac{803.84}{3}.

Finally, divide 803.84 by 3 to get the final answer of 267.947 in^3.

Ms.Wright opens a savings account with a deposit of $800. The bank will pay her 3% interest per year A.) how much interest will
Norma-Jean [14]

A) Ms.Wright receive $12 as interest at the end of 1/2 year.

B)  Ms.Wright receive $24 as interest at the end of 1 year.

Step-by-step explanation:

The sum deposited in the bank = Principle  = $800

The rate of simple interest  = 3%

The time = 6 months  = (6/12) years   =  0.5 years

\textrm{SIMPLE INTEREST} =  \frac{P \times R \times t}{100} \\\implies SI  = \frac{800 \times 3 \times 0.5}{100}  = 12

So, here simple interest = $12.

So Ms.Wright receive $12 as interest at the end of 1/2 year.

B) Now here Time  = 1 year

so, Simple interest   = \frac{800 \times 3 \times1 }{100}  = 24

So Ms.Wright receive $24 as interest at the end of 1 year.
