Answer:
3 : 7
Step-by-step explanation:
Let the radii be 3x, 7x.
Circumference = 2πr, where r = radius
Thus, ratio of circumference:
2 × π × 3x : 2 × π × 7x
= 3 : 7

The price of a wardrobe is decreased by 38% and now is $27.28.
Find the original price.
Answer:
$44
Step-by-step explanation:
The original price of the wardrobe = 100%
If the wardrobe was decreased by 38%, then the discounted price of the wardrobe = 100% - 38% = 62%
Therefore, $27.28 = 62% of the original price.
62% = 62/100 as a ratio
Using ratios, and letting [tex]x[/tex] be the original price:
27.28/[tex]x[/tex] = 62/100
Cross multiply: 27.28 x 100 = 62 x [tex]x[/tex]
2728 = 62[tex]x[/tex]
Divide both sides by 62: 44 = [tex]x[/tex]
Therefore, the original price of the wardrobe was $44
Alternatively, divide 27.78 by 62 to get the cost per 1%. Then multiply this by 100 to get the original price (100%):
(27.78 ÷ 62) x 100 = 44

1) What mistake did I make?
2) What suggestion would you give me to avoid making that same mistake in the future?
Answer:
1) The mistake u made is in the work step 2 when u transposed 4 to the side of 12 you should have changed the sign. It should have been multiplication.
2) Just recheck it once.
So, x was 48
Step-by-step explanation:
Equation:
x/4 - 5 = 7
Transpose 5 first.
So,
x/4 = 7 + 5
(Remember to change the sign when u transpose 5 to the RHS)
So,
x/4 = 12
Transpose 4.
So,
x = 12 × 4
x = 48
Recheck,
Substitute x with 48
48/4 - 5 = 7
Let's check:
48/4 = 12
Now 12 - 5 = 7
So, 7 = 7

Answer:
18.50 ft
Step-by-step explanation:
Add 1.25 to the length:
3 + 1.25 = 4.25
The formula for the perimeter of a rectangle is: L + L + W + W.
To find the perimeter quicker, multiply the length and width by 2, then add.
5.00(2) = 10.00
4.25(2)= 8.50
10.00 + 8.50 = 18.50

• Congruent triangles are identical triangles, with same dimensions and same geometry, same area and perimeter.
Step-by-step explanation:
[tex].[/tex]
The Congruent Triangles are HJK and NLM.
What is Congruency?Congruent denotes similarity in size and form. It doesn't matter if they are reversed or mirror reflections of one another. They are regarded as congruent if you could cut them out and stack them side by side to demonstrate that they are the same size and shape.
We have,
In Triangle HKJ
< H is 58 degrees.
< J is 62 degrees.
< K is 60 degrees
and, in Triangle LMN
< N is 58 degrees.
< L is 62 degrees.
< M is 60 degrees.
Thus, Triangle HJK is congruent to Triangle NLM.
