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

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

The equation of a line is y = 3. Write an equation in slope-intercept form of a line parallel to y = 3 that passes through (0, 6

ANEK [815]

A line that is parallel to y = 3, a horizontal line, would also be a horizontal line.
The only option that is a horizontal line passing through (0,6) is y = 6.

Given:

$m\angle B=90^\circ, m\angle D=90^\circ, AB=6, BD=4, BC=2, DE=x$ .

To find:

The value of x.

Solution:

In triangles ABC and ADE,

$\angle B\cong \angle D$ (Right angles)

$\angle A\cong \angle A$ (Common angles)

$\Delta ABC\sim \Delta ADE$ (AA property of similarity)

We know that the corresponding sides of similar triangles are proportional. So,

$\dfrac{AB}{AD}=\dfrac{BC}{DE}$

$\dfrac{6}{(6+4)}=\dfrac{2}{x}$

$\dfrac{6}{10}=\dfrac{2}{x}$

$\dfrac{3}{5}=\dfrac{2}{x}$

On cross multiplication, we get

$3\times x=5\times 2$

$3x=10$

$x=\dfrac{10}{3}$

Therefore, the value of x is $\dfrac{10}{3}$ units.

Answer:

No solution (if the fractions were squared)

Step-by-step explanation:

If you multiply by 5..you would get k^2=-1/243. Since you can't have a negative squared, you would have no solution
