The perimeter of a rectangle is 42 cm. The length is 3 cm greater than the width. Find the width and length

Answers

Answer:

width:9

length: 12

Step-by-step explanation:

width: substitute for x

length: since the length is 3 cm greater than the width, we substitute it for x+3.

we know that you need to add all the lengths to find the perimeter, and we know that the perimeter of the rectangle is 42 cm, so our equation is formed.

x+x+x+3+x+3=42

4x+6=42

4x=36

x=9

width:9

length:9+3=12

Step-by-step explanation:

1/2, 0.12, 2/3, 0.6

im going to switch each to decimal if it isn't already

1/2 = 0.5

2/3 = 0.666 repeated

so now we have

0.5 , 0.12, 0.666 repeated, 0.6

now im going to put them in order

0.666 repeated, 0.6, 0.5, 0.12

now im going to change them back

2/3, 0.6, 1/2, 0.12

Answer: 2/3, 0.6, 1/2, 0.12

Step-by-step explanation:

First I'm going to convert the fractions to decimals:

1/2 = 0.5 and 2/3 = 0.7 (rounded). Now the problem looks like: 0.5, 0.7, 0.12, 0.6. Organizing from greatest to least: 0.7, 0.6, 0.5, 0.12

Manuel wants to go snowboarding with his friends. The closest ski and snowboard resort is approximately 20 miles west and 50 miles north from his house. Manuel picks up his friend who lives 15 miles south and 10 miles east of Manuel's house. How far are the two boys from the resort

Answers

Answer:

Step-by-step explanation:

First we need to calculate the displacement of the resort from Manuel's house using Pythagoras theorem.

S1 = √50²+20²

S1 = √2500+400

S1 = √2900

S1 = 53.85m

Next is to calculate the displacement of Manuel's friend house to Manuel's house.

S2 = √15²+10²

S2 = √225+100

S2 = √325

S2 = 18.03m

The displacement of the two boys from the resort will be ∆S = S2-S1

∆S = 53.84-18.03

∆S = 35.81m

At a sale, dresses were sold for $144 each. If the dresses originally cost $200, what percentage of its original price was a dress sold for?

Answers

Answer:

72%

80% of 200 is 160.

75% of 200 is 150.

74% of 200 is 148.

72% of 200 is 144

Just to make sure ask google or siri "What is 72% of 200?".

Hope this helps!

Answer:

28% (because it was marked down by $56 dollars)

Step-by-step explanation:

144/200 = 72%

100% (200) - 72% (144) = 28% (56)

56/200 = 28%

28% (56) + 72% (144) = 100% (200)
