Step-by-step explanation:

Given the statement: Tyler's height is 57 inches.

To find his height in centimeters.

A rectangular waterbed is 8 ft long, 5 fr, wide and 1 ft tall.
rosijanka [135]

Answer: 308 gallons of water.

Step-by-step explanation:

First find the volume of the water been.

The volume of a rectangular prism uses the formula

V= L * W *H

V = 8 * 5 * 1

V = 40 ft^3

Now we will convert 40ft into gallons using what they gave us that 1 gallon is 0.13 ft^3  

\frac{1}{x} = \frac{0.13}{40}    which means if 1 gallon is 0.13 cubic feet how much will 40 cubic feet be when converted to gallons.

Solve by cross product.

0.13x = 40  divide both sides by 0.13  

x= 308

Slope = one third, y-intercept=-1
LuckyWell [14K]
In y = mx + b form, the slope is in the m position and the y int is in the b position.

y = mx + b...slope(m) = 1/3....y int (b) = -1

y = 1/3x + (-1) or y = 1/3x - 1
