Abathtub is in the shape of a rectangular prism. its dimensions are 5 feet by 3 feet by 18 inches. the bath tub is 3/4 full of water and drains at a rate of 1 cubic foot per min. about how long does it take for all the water to drain

Find the volume of the bath tub by multiplying all the dimensions together:

18 inches = 1.5 feet:

5 ft x 3 feet x 1.5 feet = 22.5 cubic feet.

The tub is 3/4 full so multiply the volume by 3/4 to find the amount of water in the tub:

22.5 x 3/4 = 16.875 cubic feet of water.

The tub drains at 1 cubic foot per minute, so it would take about 17 minutes to drain.    (16.875 rounded to the nearest whole minute).

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
