Who could help me please and thank you

The volume of a beack ball is 905 square centimeters. Find the radius of the ball to the nearest whole number.

lubasha [3.4K]

<h3>given:</h3>

$v = 905 \: {cm}^{3}$

the radius of the given ball (sphere).

<h3>solution:</h3>

$r = \sqrt[3]{ \frac{3v}{4\pi} }$

$r = \sqrt[3]{ \frac{3 \times 905}{4\pi} }$

$r = 6 \: cm$

<u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>radius</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>ball</u><u> </u><u>is</u><u> </u><u>6</u><u> </u><u>cm</u><u>.</u>

note: refer to the picture I added on how you can change r as the subject of the formula.

Dwayne walks a total of 960 feet around 3 sides of a square city block. Which

Ugo [173]

Answer:

The perimeter is 1280ft

Step-by-step explanation:

Let the side length of the square be s.

Then the distance around three sides is 3s.

According to the question the distance around 3 sides of a square city block is 960 feet.

This implies that:

$3s = 960$

$s = \frac{960}{3}$

$s = 320$

The perimeter of a square is

$p = 4s$

Substitute s=320 to get:

$p = 4(320)$

$p = 1280$

The perimeter is 1280 ft

Marilyn's net pay will increase by $18.15 as her Federal Withholding Allowance increases from 3 to 4.

<h3>What is Federal Withholding Allowance?</h3>

A Federal Withholding Allowance is an exemption that lowers the amount of income tax you must deduct from an employee's paycheck.

Given: The following are the deductible computation:

For federal withholding allowance = 3:

Social Security Tax: 6.2% of $810 = $\frac{6.2\times810}{100}$ = $50.22
Medicare tax : 1.45% of $810 = $\frac{1.45\times810}{100}$ = $11.745
State tax: (21% of 3)% of $810= $\frac{21\times3 }{100} \times\frac{810}{100}$ = 0.63% of $810 = $\frac{0.63\times810}{100}$ = $5.103

Total = $67.068; deducted amount of his gross pay = $810 - $67.068 $742.932 (3 federal withholding).

For Federal Withholding Allowance = 4:

State tax: (21% of 4)% of $810 = $(\frac{21\times4}{100}) \times\frac{810}{100}$ = 0.84% of $810 = $\frac{0.84\times810}{100}$ = $6.8704

Thus, as we can see from the calculations, the State taxes increased from $5.103 to $6.8704. Hence, the net pay increases by $18.15 as the federal allowance increases from 3 to 4.
