An mp3 player is on sale for 25% off. The original price is $52.60. What is the sale price?

Paha777 [63]

First, you need to find 25% of 52.60

Convert 25% to decimal:
25% = .25

Find 25% by multiplying its decimal equivalent by the sales price.

.25 x 52.60 = 13.15

Next, subtract that amount from 52.60 to find the new sale price.

52.60 - 13.15 = 39.45

The final price is $39.45

Answer:

148

Step-by-step explanation

A you may have studies,

x+125+23=180

x+148=180

x=132

Angle S = 132

but to find ? you have to add U and T

so it's y=125+23=148

Answer:

<h2>The circumference is multipled by 4.</h2>

Step-by-step explanation:

The formula of an area of a circle"

$A=\pi r^2$

The formula of a circumference of a circle:

$C=2\pi r$

The area multipled by 16:

$16A=16\pi r^2\\\\16A=\pi(4^2r^2)\\\\16A=\pi(4r)^2$

The radius has increased fourfold, therefore:

$C'=2\pi(4r)=4(2\pi r)=4C$

The circumference is multipled by 4.

You can calculate the area and check the circumference:

$r=11.6\ in\\\\A=\pi(11.6)^2=132.56\pi\\\\16A=(16)(134.56\pi)=2152.96\pi\ in^2$

Calculate the radius:

$\pi r^2=2152.96\pi$ <em>divide both sides by π</em>

$r^2=2152.96\to r=\sqrt{2152.96}\\\\r=46.4\ in$

Calculate the circumference of both circles:

$r=11.6\ in\\\\C=2\pi(11.6)=23.2\pi\ in$

$r=46.4\ in\\\\C'=2\pi(46.4)=92.8\pi\ in$

$\dfrac{C'}{C}=\dfrac{92.8\pi}{23.2\pi}=4\to C'=4C$
