Hi There!

Step-by-step explanation:

Find Common Denominators,

2/7 = 6/21

1/3 = 7/21

Her son washed the most lanudry.

6/21 + 7/21 = 13/21

21/21 - 13/21 = 8/21

Answer:

8/21 of the laundry still needs to be washed.

When using the vertical line test to determine if a graph represents a function, the line can only touch the relation

I need assistance!!!!
erastovalidia [21]

Answer:

Step-by-step explanation:

Because midpoints were used to make similar triangles we can say

AC=2(DE)

5x+12=2(9x-20)

5x+12=18x-40

-13x+12=-40

-13x=-52

x=4

AC=5x+12

AC=5(4)+12

AC=20+12

AC=32

There are 1,200 students at Roosevelt middle school. There are 700 boys at the school. What percentage of the students at Roosev
Stella [2.4K]
Out of 1,200 students, 700 are boys. Therefore, the fraction would be \frac{700}{1200}.

To convert this into a percentage, divide 700 by 1,200.

\frac{700}{1200} = 0.583333 (or just 0.583 if you round)

Multiply 0.583 by 100 to get a percentage.

0.583 · 100 = 58.3

So, the percent of boys at the school is 58.3%.

Three vertices of the trapezoid are A(4d,4e), B(4f,4e), and C(4g,0). The fourth vertex lies on the origin. Find the midpoint of
satela [25.4K]
We have that

point C and point D have y = 0-----------> (the bottom of the trapezoid).

point A and point B have y = 4e ---------- > (the top of the trapezoid)

the y component of  midpoint would be halfway between these lines
 y = (4e+ 0)/2 = 2e. 

<span>the x component of the midpoint of the midsegment would be halfway between the midpoint of AB and the midpoint of CD.

x component of midpoint of AB is (4d + 4f)/2.
x component of midpoint of CD is (4g + 0)/2 = 4g/2.
x component of a point between the two we just found is
[(4d + 4f)/2 + 4g/2]/2 = [(4d + 4f + 4g)/2]/2 = (4d + 4f + 4g)/4 = d + f + g. 

</span>therefore

the midpoint of the midsegment is (d + f + g, 2e)
