ABCD ~ FECG

Please helpp
Answers
=========================================================
Explanation:
Notice how EC = 5 doubles to BC = 5+5 = 10
So the larger quadrilateral (ABCD) has side lengths that are exactly twice as long compared to the smaller quadrilateral's sides. We can say the scale factor is 2.
This must mean that side FG = 4 doubles to 4*2 = 8, which is the length of side AD. So that's how we get y = 8.
-----------------------------------
Extra info:
x = 12 because side EF = 6 doubles to this value. w = 120 because the corresponding angles of ABCD pair up with FECG, so we see that angle D = angle G = 120.z = 80 because we solve F+E+C+G = 360 to find that F = 80, which leads to angle A = 80 as well.Length of AD, y = 8
What are similar quadrilateral?Two quadrilaterals are similar if their corresponding angles are equal and also their corresponding sides must be proportional.
Given,
EC = 5
FG = 4
BE = 5
AD = y
ABCD ~ FECG,
then ratio of the corresponding sides will be equal.
BC/AD = EC/FG
(BE + EC)/AD = EC/FG
(5 + 5)/y = 5/4
10/y = 5/4
5y = 40
y = 40/5
y = 8.
Hence, 8 is value of y that is length of AD.

Think About the Process Van purchased a DVD player on sale. The original
selling price was $175.90. The sale price was $149.62. What is the first step in
finding the percent markdown? Find the percent markdown.
much appreciated if helped :(
Answers
Answer:
14.940306992% or 15%
Step-by-step explanation:
To solve for percent or price markdown, you first have to find the difference between the original selling price and the sale price.
$ 175.90 - $ 149.62 = $26.28
Then, find the percentage that $26.28 is of the original selling price. You are decreasing the original by this much to get to the sale price.
$26.28 / $175.90
= 0.14940306992
Finally, multiply by 100 and round up to reach a percentage.

Tanya is n years old today. How old will she be in 5 years
Answers
Answer:
n+5
Step-by-step explanation:
Answer:
n + 5 or 5 + n
Step-by-step explanation:
add 5 to n, tanya's current age, to find how old she'll be in 5 years.
since the variable n is not defined, the answer cannot be simplified further than n + 5.
if n had been defined, you would be able to figure out her exact age after 5 years, which would be the fully simplified answer. for example, if n were to equal 10, then tanya would currently be 10 years old. by plugging in 10 for n in n + 5, you would figure out that in 5 years (aka 10 + 5) tanya would be 15.

Answer:
SA = 126 square cm
Step-by-step explanation:
SA = 2(l · w) + 2(h · w) + 2(l · h)
SA = 2(5 · 6) + 2(6 · 3) + 2(5 · 3)
SA = 60 + 36 + 30

The surface area of the cuboid box is S = 126 cm²
What is the surface area of cuboid?
A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges
The total surface area of the cuboid is given by the formula
Surface Area = 2 ( LH + LW + HW )
where ,
Length of the cuboid = L
Width of the cuboid = W
Height of the cuboid = H
Given data ,
Let the surface area of cuboid be S
Length of the cuboid = L = 6 cm
Width of the cuboid = W = 5 cm
Height of the cuboid = H = 3 cm
On simplifying , we get
Surface Area = 2 ( LH + LW + HW )
S = 2 ( ( 6 x 5 ) + ( 6 x 3 ) + ( 5 x 3 ) )
S = 2 ( 30 + 18 + 15 )
S = 2 ( 63 )
S = 126 cm²
Hence , the surface area is S = 126 cm²

what is two numbers that add to 20 and the difference is 6
Answers
13 and 7.
Steps
x + x = 20
x - x = 6
2x = 26
x = 13
x = 20 - 13
x = 7
Answer:
13 and 7
Step-by-step explanation:
We have two unknown numbers that add up to 20 and subtract to 6. The question is asking us to find out these two hidden numbers.
Let's form two equations.
x + y = 20
and
x - y = 6
Since we have a positive y and negative y, we can use the addition method to these systems of equations.
x + y = 20
x - y = 6
+-----------------
2x = 26
Now isolate x to get x.
Divide both sides by 2 :
x = 13
Now that we have x, we can plug it into the equations.
13 + y = 20
13 - y = 20
So what number will make this true. Use the backwards method :
20 - 13 = 7
Therefore, 13 and 7 are our two numbers.

Answers
Answer: X = -4
Step-by-step explanation:
90 - 5x + 62 -2x = 180
152 - 7x = 180
-7x = 28
x = -4
Check your answer by pluging in the vaule of x
90 - 5(-4)
90 + 20 = 110
62 - 2(-4)
62 + 8 = 70
110 + 70 = 180
Checks out.
Answer: 110 degrees and 70 degrees
Step-by-step explanation:
These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180
Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180
Subtract 152 from both sides of the equation.
-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70
We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180
