Answer:

length is 20 and the width is 5

Step-by-step explanation:

so Area is 100

Area = width * length

legth = 4 * width

This means:

Area = width * 4 width =>  Area = 5 * width

We know that area is 100 so:

100 = 5 * width

that means width = 20, but wait didn't I say that the length is 20? Yes, remember we said length = 4 * width at the beginning, so <u>length = 20</u>.

Now we can easily calculate width as width is 4 times smaller than length, so:

<u>width = 20/4 => 5</u>

We can also test if this is correct by simply using the formula to calculate rectangle. So 5 * 20 = 100, correct!

Which equation is a quadratic model for the data set? Hint: Use a graphing calculator or a spreadsheet program.
Ivahew [28]

The equation that model a quadratic function is:  y=0.9673x²-0.8475x+10.4334

Step-by-step explanation:

A quadratic function has the form of ;

f(x) = ax²+bx+c  where a, b and c are real numbers and a≠0

For this case, equation y=0.9673x²-0.8475x+10.4334 models a quadratic function where a>0 thus the parabola opens upwards

A container shaped as a rectangular prism can hold 840 wooden cube blocks with edge lengths of
asambeis [7]
First, fidn the volume of the little cubes that the rectangular prism can hold instide of itself. The formula for volume is length x width x height. This means you have to multiply 1/2 x 1/2 x 1/2. 1/2 x 1/2 x 1/2 = 1/8. Now, since the rectangular prism can hold 840 of these cubes, you need to multiply each cube's volume, 1/8, by 840. 1/8 x 840 = 105.

Your answer should be: 105 ft.^3
