First you convert 20% into a decimal which is 0.2 and multiply that by 42 and you get 8.4, that's the discount. Then you subtract 8.4 from 42 and get $33.60 which is your answer. Hope this helps!!

The length of the rectangle is three more than the width find the length of the rectangle if the perimeter is 98 inches

Aleks [24]

Answer:

length is 26 and width is 23

Step-by-step explanation:

let width be x

then length is 3+x since it is 3 more than the width

perimeter of a rectangle = 2l + 2w

98=2 [3+x] + 2x

98=6+2x+2x

98=6+4x

98-6=4x

92=4x

x=23

width is 23 and

breadth is 26

Saira is using the formula for the area of a circle to determine the value of .

klio [65]

For this problem, we just have to use the values we're given to calculate the approximate value of pi.

The formula presented is

$\pi=Ar^{-2}$

When you have a negative exponent, we can use the following property

$a^{-b}=\frac{1}{a^b}$

Using this property, our problem turns out to be

$\pi=\frac{A}{r^2}$

Now, we just need to plug the given values on this equation

$\pi=\frac{50.265}{4^2}=3.1415625\approx3.142$

The approximated value for pi is 3.142.
