Parallelogram ABCD is dilated to form parallelogram EFGH. Side BC is proportional to side CD. Which corresponding side is propor

notsponge [240]

Answer:

It is given that , Parallelogram ABCD is dilated to form parallelogram EFGH.

When Dilation of a geometrical shape takes place, the two→→image and Pre image will be Similar.

Parallelogram ABCD ~ Parallelogram EFGH

Since Similar shapes have , Proportional side Lengths as well as length of their Diagonal will be proportional.

$\frac{AB}{EF}=\frac{BC}{FG}=\frac{CD}{GH}=\frac{AD}{EH}=\frac{AC}{EG}=\frac{BD}{EG}$

So, Segment FG will be proportional to Segment BC.

If Jasper installs a floor himself, it will take him 7 hours. Working with Yolanda, it will take them 3 hours.

Svetllana [295]

Answer: 5 $\frac{1}{4}$ hrs

<u>Explanation:</u>

Jasper: $\frac{1}{7}$ per hr

Yolanda: $\frac{1}{x}$ per hr

Together: $\frac{1}{3}$ per hr

Jasper + Yolanda = Together

$\frac{1}{7}$ + $\frac{1}{x}$ = $\frac{1}{3}$

$(21x)\frac{1}{7}$ + $(21x)\frac{1}{x}$ = $(21x)\frac{1}{3}$

3x + 21 = 7x

21 = 4x

$\frac{21}{4}$ = x

$5\frac{1}{4}$

What is the total area of the prism?

Pavlova-9 [17]

First we look for the area of the triangle which is given by:
A = (1/2) * (4) * (6)
A = 12 feet ^ 2
Area of the rectangles:
Rectangle 1:
R1 = (4) * (8)
R1 = 32 feet ^ 2
Rectangle 2:
R2 = (6) * (8)
R2 = 48 feet ^ 2
Rectangle 3:
R3 = (root (6 ^ 2 + 4 ^ 2)) * (8))
R3 = 57,68882041 feet ^ 2
The total area will be:
A = 2A + R1 + R2 + R3
Substituting values:
A = 2 * (12) + 32 + 48 + 57,68882041
A = 161.6888204 feet ^ 2
Answer:
The total area of the prism is:
A = 161.6888204 feet ^ 2
