Answer:

1 inch

Step-by-step explanation:

volume of first cylinder = volume of  second cylinder because it never changes it stays the same

volume of first cylinder = (pi) (1)^2 (4) = 4pi

height of second cylinder: 4pi = (pi) (2)^2 h

pi would cancel so you are left with 4=4h

where height of second cylinder would be 1 in

A suit is on sale for 72% off. The sale price is $263.20.<br> What is the regular price?
Elis [28]

Answer:

940

Step-by-step explanation:

<em>To find the original price of something that been discount do the following:</em>

  • <em>Subtract the discount from 100 to get the percentage of the original price.</em>
  • <em>Multiply the final price by 100.</em>
  • <em>Divide by the percentage in Step One.</em>

<em>Or we can do the following:</em>

<em>We shall consider the original price as x; hence the discount can be considered as (x−263.20). We can write the equation:</em>

<em>x · 72/100=x - 263.20</em>

<em>x · 18/25 = x - 263.20</em>

<em>Multiply both sides by 25</em>

<em>18x = 25(x - 263.20)</em>

<em>Open the brackets.</em>

<em>18x = 25x-6580</em>

<em>Add 6580 to each side.</em>

<em>6580 +18x = 25x</em>

<em>Subtract 18x from each side.</em>

<em>6580 = 7x</em>

<em>Subtract 7x from each side.</em>

<em>x = 940</em>

<em>Check Answer:</em>

<em>940 * 72% = 676.80</em>

<em>940 - 676.80=263.20</em>

<em>Hence, the regular price is 940.</em>

At the 2/8 part, just use the quadratic formula.  If you use it, you should get the other two zeroes:

-4+\frac{\sqrt{14}}{2} \\ -4-\frac{\sqrt{14}}{2}

Clarissa works in sales for a software company. Her pay each month varies, because each month she receives a base pay of $2,400.
Pie

Answer:

Total earning of Clarissa for the november month is $3840 .

Step-by-step explanation:

As given

Clarissa works in sales for a software company.

Her pay each month varies, because each month she receives a base pay of $2,400.00 plus 8% commission on her sales.

During the month of November, Clarissa had $18,000.00 in sales.

8% is written in the decimal form

= \frac{8}{100}

= 0.08

Commission price = 0.08 × sales in november month .

                              = 0.08 × 18000

                              = $ 1440

Total earning in november month = Base price + Commission price

                                                         =  $2400 + $ 1440

                                                         = $ 3840

Therefore the total earning of Clarissa for the november month is $3840 .
