Answer:

6 ft

Step-by-step explanation:

The cube root of 216 is 6. So 6x6x6 = 216. A cube has all equal sides resulting in the length, 6 ft.

An art class is planning to paint a rectangular mural with an area of 60 square feet. It has to be at least 4 feet high but no m

Hello!

There are three possible lengths.

We need to keep in mind that the total area cant exceed $60 ft^{2}$ , so, knowing that, we just need to find numbers that can be multiplied giving as result 60.

First combination:

$4ft(height)X15ft(width)=60 ft^{2}$

Second combination:

$5ft(height)X12ft(width)=60 ft^{2}$

Third combination:

$6ft(height)X10ft(width)=60 ft^{2}$

Have a nice day!

A line has a slope of 8 and includes the points (1, z) and (2,8). What is the value of z?

NISA [10]

The value of z is zero

Step-by-step explanation:

The slope is the steepness of the line.

The formula for slope is given by:

$m=\frac{y_2-y_1}{x_2-x_1}\\Here\\(x_1,y_1)\ are\ the\ coordinates\ of\ first\ point\ on\ line\\(x_2,y_2)\ are\ the\ coordinates\ of\ second\ point\ on\ line$

Here

(x1,y1) = (1,z)

(x2,y2) = (2,8)

So,

$m=\frac{y_2-y_1}{x_2-x_1}\\8 = \frac{8-z}{2-1}\\8=\frac{8-z}{1}\\8-8 = -z\\z = 0$

The value of z is zero
