A scale on a blue print drawing of a house shows that 10centimeters represents 2 meters. What number of actual meters are represented by 18 centimeters on the blue print?

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

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

step-by-step explanation:

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
