Step-by-step explanation:

Convert the percent to a decimal  4,000%

4000% = 4000/100 = 40.0

Convert the decimal or whole number to a percent.

0.36 * 1/2

= 0.36/2 * 100

= 0.18 * 100

= 18%

Convert the decimal or whole number to a percent.

1.15 * 1/8

= 1.15/8 * 100

= 14.375%

Convert the percent to a reduced fraction, mixed number, or whole number.

0.4%

= 0.4/100

= 1/250

Solve for the portion (in $). Round to hundredths when necessary.

9  1/2% of $400 = 19/2% x 400

= 0.095 x 400

= 38

Solve for the portion. Round to hundredths when necessary.

What number is 253% of 2,500?

253/100 x 2500

= 2.53 x 2500

= 6325

!!

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
