As a part of a science experiment, Gary makes a small hole in the bottom of a bottle full of water. He records the amount of water left in the bottle at the end of each minute. He repeats
this experiment several times and uses the data to develop the linear model, w = -50m + 1200,
which describes the amount of water remaining in the water bottle, in w milliliters, after m
minutes. Which statement is a correct interpretation of this linear model?
A. The water bottle holds 1,200 milliliters of water and loses 50 milliliters per minute.
B. The water bottle starts with 1,200 milliliters of water and ends with 24 milliliters of water.
C. The water bottle holds 1,200 milliliters of water and loses 1 milliliter of water every 50
minutes.
D. The water bottle starts with 1,200 milliliters of water and loses exactly 50 milliliters of water.
Hi

47 - 90 = 43

43 - 180 = x

x = 137

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:

70.30

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
