3/4 of 120 would be 90.
If you divide 120 into 4 equal parts, each part would be worth 30, because 30 multiplied by 4 is 120. So, to find how many 3 parts would equal, you add 30 plus 30 plus 30. 
You get 90. So, Megan has 90
3/8 of 160 would be 60 
If you divide 160 into 8 equal parts, you get 20 for each part, because 20 multiplied by 8 is 160. So to find how many 3 parts would equal, you add 20 plus 20 plus 20.
you get 60. So, Alex has 60.
The question is asking you how many more Megan has. Well, Megan has 90, and Alex has 60. 90 - 60 is 30.
Your answer would be 30.
I hope this helped

<h3>Answer:  4368 square feet</h3>

======================================================

Explanation:

Check out the diagram below

I drew a rectangle with dimensions 56 ft by 78 ft.

Then I broke up the 56 into 50+6, and I broke up the 78 into 70+8

The reason for this is because it's fairly easy to multiply the areas of each smaller rectangle at this point

  • In the upper left corner, we have an area of 50*70 = 3500. Note how this is basically 5*7 = 35, but we tack on the two zeros (from 50 and 70 combined)
  • In the upper right corner, we have an area of 70*6 = 420
  • In the lower left corner, we have an area of 50*8 = 400
  • In the lower right corner, we have an area of 6*8 = 48

Add up all the areas found: 3500+420+400+48 = 4368

As a way to check, using your calculator shows that 56*78 = 4368

Calculate the area of triangle ABC with altitude CD, given A (6,0) B(1,5) C (2,0) and D (4,2)
Elina [12.6K]
So hmm check the picture below

the height or altitude is CD
and the base is AB

how long are those? well \bf \textit{distance between 2 points}\\ \quad \\&#10;\begin{array}{lllll}&#10;&x_1&y_1&x_2&y_2\\&#10;%  (a,b)&#10;A&({{ 6}}\quad ,&{{ 0}})\quad &#10;%  (c,d)&#10;B&({{ 1}}\quad ,&{{ 5}})\\\\&#10;C&({{ 2}}\quad ,&{{ 0}})\quad &#10;%  (c,d)&#10;D&({{ 4}}\quad ,&{{ 2}})&#10;\end{array}\qquad &#10;%  distance value&#10;d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}&#10;\\\\\\&#10;AB=\sqrt{(1-6)^2+(5-0)^2}\qquad \qquad CD=\sqrt{(4-2)^2+(2-0)^2}
