Find the area of the quadrilateral

Mathematics
1 answer:
Vedmedyk [2.9K]3 years ago
6 0

Answer:

A=40'

Step-by-step explanation:

To me, it seems that the figure is a parallelogram.

So, let's use the formula to calculate the area of a parallelogram.

<h2><em><u>A=bh</u></em></h2>

In this case, the base <em>(b)</em> is 8' and the height <em>(h)</em> is 5'.

Replace the variables with our new values.

<em><u>A=bh</u></em>

<em><u>A=8*5</u></em>

<em><u></u></em>

Calculate the sum.

8*5=<em><u>40</u></em>

<em><u></u></em>

Add units.

40' or 40 inches.

Hence, 40 inches (40') is our answer.

Hope this helps

Can someone help me with the 2 highlighted questions?
dexar [7]

Answer:

2. domain: {3,4,5,6,7}; range: {2,3,4,5,6}

4. IS a function

Step-by-step explanation:

2. The <em>domain</em> is the list of first numbers of each pair.

The <em>range</em> is the list of second numbers.

4. If each value on the left only has <em>one arrow</em> coming from it, the relation <u>is</u> a function. That is the case here.

__

Contrast that to the problem above (3.). In that one, the number 4 1/2 has two arrows coming from it. That relation is NOT a function.

Original price of a CD is $17.50 discount is 50%​
ladessa [460]

Answer:

$8.75

Step-by-step explanation:

To calculate this you could use two methods. The first method is to find out what 10% is and multiply it by 5. The second method is to calculate 50% using the formula.

<u>Method 1:</u>

To work this out you would simply divide 17.50 by 10, which is 1.75. This is because percentages are out of 100 and so by dividing by 10 we are finding out what 10% is. Then you would multiply 1.75 by 5, which is 8.75. Then you would minus 8.75 from 17.50, which is 8.75.

<u></u>

1) Divide 17.50 by 10.

17.50/10=1.75

2) Multiply 1.75 by 5.

1.75*5=8.75

3) Minus 8.75 from 17.50.

17.50-8.75=8.75

4) The new price is $8.75

<u>Method 2:</u>

<u></u>

The formula for percentages is.

\frac{percentage}{100} * amount

<u></u>

To work this out you would first divide 50 by 100, which gives you 0.5. Then you would multiply 0.5 by 17.50, which is 8.75. Then you would minus 8.75 from 17.50, which is 8.75.

1) Divide 50 by 100.

50/100=0.5

2) Multiply 0.5 by 17.50.

17.50*0.5=8.75

3) Minus 8.75 from 17.50.

17.50-8.75=8.75

4) The new price is $8.75.

3x − 15= 3x + 15<br> what is x?
Marina CMI [18]

We are given the following equation and want to find the possible values of x

3x-15=3x+15

Subtract both sides by 3x

3x-15-3x=3x+15-3x

-15=15

Now, we have this weird equation. Since -15 is NOT equal 15 and there is no other way we could have solved for x, there is no real solution to the given equation.

In other words, there is no value of x that makes the equation true.

Let me know if you need any clarifications, thanks!
