Mattress Warehouse is having a sale on all mattresses. A twin and a king-size mattress are similar rectangles, and the ratio of the corresponding sides is 2:3. If the area of the king-size mattress is 108 ft^2
what is the area of the twin mattress?
1.48 ft^2
2.72 ft^2
3.90 ft^2
4.162 ft^2

Answers

Answer 1

Answer:

Number 3

Step-by-step explanation:

Answer 2

Answer:

1. 48 ft²

Step-by-step explanation:

The ratio of sides is

Twin/king = 2/3

The area is the product of two sides so the ratio of the areas is the square of the ratio of the sides:

A(twin) / A(king) = (2/3)²x/108 = 4/9x = 108*4/9x = 48 ft²

PLEASE HELP THIS IS VERY IMPORTANT I WILL GIVE YOU BRAIN THING IF ITS CORRECT (you can use a calculator if you want)

Answers

Answer:

Step-by-step explanation: if there are 500 pieces of paper and the entire stack is 1.875 inches tall, you devide the total height by 500. I know Deigo is wrong because you can easily reverse check his work by multiplying 0.015 by the total number of papers 500 you will get 7.5 which is not the height of the stack

1.875/500=0.00375

each piece of paper is 0.00375

After an awards show, Miller has these leftover flowers: 163 carnations, 240 daisies, and 189 lilies. If he uses all of these in a Flower Flash, what percent are daisies?​

Answers

To find the percent, you must use the formula part/whole x100
So we must find the whole...
163+240+189= 592
Now we put the number of daisies over the whole
240/592= 0.405405405405405
Then multiply is by 100 to make it a percent

40.5%

Step-by-step explanation: you have to have a common denominator so you take 3 and 9 and find what they both go into and that number is 9 so take 2/3 and times the top and bottom by 3 to get 6/9 and 2/9 by 1 to get 2/9 once you have those subtract them to get 4/9 and that's your first answer then take them and add so you get 8/9 which is your second answer

PLS ANSWER

Answers

Answer:

I believe that the answer is 21x+14 and 7(3x+2).

Step-by-step explanation:

I hope this helps, have a blessed day.

Answer:

A. 21x + 14 and 7(3x + 2).

Step-by-step explanation:

23x - 14 + 2x = 21x + 14

25x - 14 ≠ 21x + 14

x + x + 5 = x² + 5

2x + 5 ≠ x² + 5

9x² + 9x + 5 ≠ 18x² + 5

21x + 14 = 7(3x + 2)

21x + 14 = 21x + 14.

Your answer is A, 21x + 14 and 7(3x + 2).

A rectangle has sides that are 10 m, 10m, 5m, and 5 m. What is the rectangle’s length?
5m
20 m
10 m
30 m

Answers

The way the question is worded is a little confusing.

I think I would say 10m. It could be 5m, but usually they list length first, then width. The perimeter, the whole distance around the outside, is 30 m (10 + 10 + 5 +5)

The length of the rectangle will be 10 m.

What is a rectangle?

A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.

Given that, a rectangle has sides that are 10 m, 10 m, 5 m, and 5 m.

We need to find the length of the rectangle,

We have the dimensions 5 m x 10 m,

Lengths in a rectangle tells that how much the rectangle is long and the width tells how much the width tells about the breadth of the rectangle,

So, we can say that,

Length = 10 m

Width = 5 m

Hence, the length of the rectangle is 10 m.
