The diagonal of a rectangle is 100 units. The width is 80 units. What is the area of the rectangle in square units.

4800 square units

Step-by-step explanation:

a²+b²=c²so

80²+b²=100²

6400+b²=10000  (subtract 6400 from both sides)

3600=b² (square root both sides)

b=60

A=bw so

60(80)=

4800 square units

answer: 12

step-by-step explanation:

because yes

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
