Answer:

Step-by-step explanation:

Draw the diagram.

This time put in the only one line for the height. That is only 1 height is 8 cm. That's it.

The base is 6 + 6 = 12 cm.

The slanted line is 10 cm

That's all your diagram should show. It is much clearer without all the clutter.

Now you are ready to do the calculations.

Area

The Area = the base * height.

base = 12

height = 8

Area = 12 * 8 = 96

Perimeter.

In a parallelagram the opposite sides are equal to one another.

One set of sides = 10 + 10 = 20

The other set = 12 + 12 = 24

Both sets = 20 + 24

Both sets = 44

Answer

Area = 96

Perimeter = 44

Answer:

Area = 108 cm^2

Perimeter = 44 cm

Step-by-step explanation:

Area, -->

24 + 30 + 24 + 30 -->

24(2) + 30(2)

48 + 60 = 108 cm^2

108 = area

10 + 12 + 10 + 12, -->

10(2) + 12(2) = 44 cm

44 = perim.

Hope this helps!

The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of mon

ivanzaharov [21]

Answer:

The slope is $0.35/min and it gives the cost per minute of the phone used.

Step-by-step explanation:

We can model this situation with a linear equation of the form

$y =mx+b$

where $y$ is monthly cost, $x$ is the number of minutes, $b$ is the flat monthly fee, and $m$ is the slope of the equation, or in our case, the amount of money charged per minute.

The slope $m$ is

$m= \dfrac{\$372.5-\$131}{990min-300min}$

$m = \$0.35/min$ ,

in other words, the phone company charges $0.5 per minute.

With the slope in hand, the linear equation becomes

$y =0.35x+b$ ,

and we can find the monthly fee $b$ from that fact that for 300 minutes the cost is $131:

$\$131 = 0.35(300min) +b$

$b = \%26$ .

Therefore,

$y = 0.35x+26$

where the slope if the equation give the cost per minute of the phone used.

Step-by-step explanation:

Step 1: Make an equation to represent the problem

(-9)(x) = 36

Step 2: Solve for x by dividing both sides by -9

-9x / -9 = 36 / -9

x = -4
