Two squares are similar. The scale factor from the first

square to the second square

is 1:3. If the perimeter of the

first square is 12 inches,

what is the perimeter of the

second square?

inches Fill in the

blank.

The perimeter of the second square is 36 inches

Step-by-step explanation:

Given

Represent the sides of the squares with S1 and S2.

So:

--- Scale factor

--- perimeter of the first

Required

Calculate P2, the perimeter of the second

Represent the ratios of the perimeter:

Substitute 12 for P1

Equate both scale factors

Convert to fraction

Cross multiply

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
