In the U.S thirteen of twenty cans are recycled. What % of cans are recycled?
madam [21]

A percent is how many out of 100.

13/20 is how many out of 100?

You multiply the top and bottom by 5, as 5x20 is 100

13x5 is 65

Therefore, 65 out of every hundred cans, or 65%, are recycled

The dimensions of a square are altered so that one dimension is increased by 7 feet and the other is decreased by 2 feet. The ar
Rufina [12.5K]

I got 64 square feet.

My work is shown in the image.

For possible questions:

1: you can find x+7 and x-2 because the sides of the square can be measured as x, and x+7 means 7 more than the original; x-2 means 2 less than the original.

2: solved via factoring. Not sure if you've learned it or not.

3: reject the negative numbers because you can't have negative sides in a square.

frozen [14]

Hey there!☺

Answer:\boxed{y=\frac{-1}{2}}

Explanation:

\frac{y}{-8}=\frac{1}{16}

In our first step, we will use the cross multiply method:

\frac{y}{-8}=\frac{1}{16}\\  y*(16)=(1)*(-8)\\16y=-8

In our second/last step, we will divide both sides by 16:

\frac{16y}{16}=\frac{-8}{16}\\y=\frac{-1}{2}

Hope this helps!☺

Please help Find the value of x
exis [7]

Answer:

Value of x is 2

Step-by-step explanation:

Given

BD = 6

DA = 4

BE = x+1

EC = x

Also segment DE is parallel to segment AC

∴ By using Midpoint theorem which states

\frac{BD}{DA}\cong \frac{BE}{EC}

Putting the given data in above equation we get

\frac{6}{4}=\frac{x+1}{x}\\6x=4(x+1)\\6x =4x+4\\6x-4x =4\\2x=4\\x= \frac{4}{2}\\x=2
