Khali and Juan are using ribbon to decorate their art project. The ratio of the length of Khali’s ribbon to the length of Juan’s ribbon is 8:5. If Khali used a total of 72 cm of ribbon, how much did Juan use?

Answers

Answer:

45 cm

Step-by-step explanation:

First, you want to clarify the ratio:

Khali = 8 cm = 72 cm

____ _____ ______

Juan = 5 cm = x cm

To find the missing variable, cross multiply and simplify for x:

8x = 72(5)

8x = 360

x = 45

So, Juan used 45 cm of ribbon if Khali used 72 cm.

Can somebody possibly solve this???Consider a rectangle, for which perimeter = 2l+2w. perimeter = 2 l + 2 w . If the length of a rectangle is 5 m or less than twice the width, and the perimeter is 44 m long, find its length and width.

Answers

Final answer:

To determine the length and width of a rectangle, we can set up an equation using the given information and solve for the variables. By substituting the width back into the equation for the length, we find that the width is 9 meters and the length is 13 meters.

Explanation:

To solve this problem, we can start by using the given information to create equations. Let's assume that the width of the rectangle is 'w' meters. According to the problem, the length of the rectangle is 5 meters or less than twice the width, so the length can be represented as 2w - 5 meters.

The formula to calculate the perimeter of a rectangle is 2l + 2w, where 'l' is the length and 'w' is the width. We are given that the perimeter is 44 meters, so we can set up the equation as follows:

2(2w - 5) + 2w = 44

Simplifying the equation, we get:

4w - 10 + 2w = 44

Combining like terms, we have:

6w - 10 = 44

Next, we can isolate the variable by adding 10 to both sides:

6w = 54

Finally dividing both sides by 6, we find that:

w = 9

Therefore, the width of the rectangle is 9 meters. Substituting this value back into the equation for the length, we find:

l = 2w - 5 = 2(9) - 5 = 18 - 5 = 13 meters.
