A deck company wants to build uniquely shaped decks. How many square feet of wood would the company need to cover the deck designed below shaped like a regular pentagon and a trapezoid? The height of the trapezoid is 4.5 ft. Round your answer to one decimal place. Hint: To find the area of the pentagon, divide it into 5 similar triangles. Use the fact that the radius of the pentagon (the distance from each vertex to the center) is 4.25 ft. 5 5 ft 8 ft

answer: 12

step-by-step explanation:

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

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
