Asquare has exactly 4 congruent sides and 4 congruent angles. which shows the statement written as a biconditional statement? ( don't be mean, i'm already sad as it is)] a) if a figure is a square, then it has exactly 4 congruent sides and 4 congruent angels. b) if a figure has exactly 4 congruent sides and 4 congruent angles, then it is a square. c) a figure is a square if and only it has exactly 4 congruent sides and 4 congruent angles. d) if a figure is a square, then it is a rectangle.

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
