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

The price of a wardrobe is decreased by 38% and now is $27.28.
Find the original price.

Answers

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

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.
