A wall measures 2 meters 30 centimeters in width. What is the width of the wall in millimeters?
A:0.0023 mm

B:0.23 mm

C:2.3 mm

D:2,300 mm

The answer is D

Step-by-step explanation:

1 meter = 1,000 millimeters

1 centimeter = 10 millimeters

2 meters = 2,000 millimeters

30 centimeters = 300

2,000+30=2,300

D. 2,300

Step-by-step explanation:

There is 1000 millimeters in a meter which gets you 2000 plus the 30 centimeters. 30 centimeters is equal to 300 millimeters because for every centimeter its 10 millimeters. Add the 2000 to the 300 and get 2300 millimeters.

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
