In the rectangle ABDF above, C and E are midpoints of sides line ED and line DF, respectively, what fraction of the areas of the

aivan3 [116]

Answer:

Is shaded 5/8 of the area of the rectangle

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of triangle ABC represent 1/4 of the total area

The area of triangle CDE represent 1/8 of the total area

The shaded region is composed by one triangle equal to triangle ABC and three triangles equal to triangle CDE

so

The area of the shaded region is equal to

$(1/4)(1)+(1/8)(3)=(1/4)+(3/8)=(2/8)+(3/8)=5/8$

therefore

Is shaded 5/8 of the area of the rectangle

Answer:

x = 3

Step-by-step explanation:

Given:

$4(x-2)+2x=10$

Step 1: $4x-8+2x=10$

Step 2: $4x+2x-8=10$

Step 3: $4x+2x-8+8=10+8$

Now Solving for next steps we get

Step 4: $6x=18$

dividing both side by 6 we get

Step 5: $\frac{6x}{6} =\frac{18}{6}$

And So the Final Answer is:

x = 3

Prove algebraically that 0.8 =8/9

-BARSIC- [3]

100x = 88.8888888.....

x = 0.8888888....

99x = 80

X = 80/99 = 0.8...

If you have a quarter of a pie and you cut it in half, what fraction of a pie would each slice represent? enter the numerator fo

yarga [219]

$\\
\text{Suppose you have a quarter of a pie, so in mathematical notation the part of }\\
\text{pie you have is}=\frac{1}{4}\\
\\
\text{now you cut this piece of quarter pie in half and make two equal part.}\\
\\
\text{so the fraction of the pie, that each slice would represent is:}\\
\\
=\text{Half of the quarter pie}\\
\\
=\frac{1}{2}\left ( \frac{1}{4} \right )\\
\\
=\frac{1}{8}$

Hence the fraction of a pie that each slice represent is: 1,8
