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>

Find the volume of the cylinder.<br> 1607.7 in 3<br> 2845.7 in 3<br> 6430.7 in 3<br> 401.9 in 3
Musya8 [376]

Answer:

\Huge\boxed{1607.7in^3}

Step-by-step explanation:

Hello There

The volume of a cylinder can be found using this formula

V=\pi r^2h

where r = radius and h = height

The cylinder shown has a radius of 8 inches and a height of 8 inches

Knowing this information we plug it in into the formula

V=\pi 8^28\\8^2=64\\64*8=512\\512\pi=1607.68

Finally we round to the nearest tenth and get that the volume of the cylinder is 1607.7 in ^3
