Answer:

x = 20

Step-by-step explanation:

Formula

x1/x2 = x3/x4

Givens

x = 11

x2 = 11 + 121 = 132

x3 = 10

x4 = 10 + 5x + 10

Solution

11/132 = 10 / (5x + 10 + 10)        Combine

11/132 = 10/(5x + 20)                Cross multiply

11*(5x + 20) = 132 * 10              Combine on the right.

11(5x + 20 ) = 1320                   Divide by 11. (You could remove the brackets, but this is easier.

11(5x + 20)/11 = 1320/11            Do the division

5x + 20 = 120                          Subtract 20 from both sides

5x + 20-20 = 120 - 20             Combine

5x = 100                                   Divide by 5

5x/5 = 100/5

x = 20

The price of a pair of shoes is $45.90. The sales tax rate is 5%. How much sales tax do you need to pay?
Ne4ueva [31]
Multiply the price by the 5% by turning the percent into a decimal.
5% = 0.05
45.90 x 0.05 = $2.295
Which can be rounded to 2.30 if needed.

125.6m^2

Step-by-step explanation:

Let R be the greater radius and r be the smaller radius

Area of the sidewalk = R^2 - r^2 - This can be the expression

= 3.14

=(R^2-r^2)

=(11^2-9^2)

=(121-81)

= 40
