Answer:

A. 7.2 centimeters

Step-by-step explanation:

The length of the base is 7.2 centimeters. The area of a rectangle is length*width

The length is unknown but the area is known. To find the length, all we have to do is divide the area from the height.

The working is as follows :

Area = 90 cm²

Height = 12.5 cm

Length = ?

Length = Area ÷ Height

= 90 ÷ 12.5

= 7.2cm

Find the slope of the line y= -3x+7

Softa [21]

Answer:

<h3>If you had a line of x = 7, (or any time you have an equation where x equals a number) then you would have a vertical line. In every vertical line, the slope is undefined. In equations of lines that are in the format of y = mx + b, the slope is represented by the "m".</h3>

In parallelogram HJKL if HM=12 find HK. K M M H L

Anestetic [448]

Answer:

HK = 24

Step-by-step explanation:

HK and JL are diagonals of the parallelogram.

Recall that diagonals of a parallelogram bisect each other. This implies that, they divide each other into equal parts.

Therefore,

HK = 2(HM)

HM = 12

Thus,

HK = 2(12)

HK = 24

Find the constant rate of change for each linear function and interpret its meaning

Marina CMI [18]

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

and to get it, we simply need two points off of the straight line, hmm let's use the ones in the picture below.

$(\stackrel{x_1}{2}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{6}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{6}-\stackrel{y1}{4}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{2}}}\implies \cfrac{2}{4}\implies \cfrac{1}{2}$
