A carpenter has a rectangular wooden board. The diagonal of the board is 18 inches long and one side of the board is 12 inches l
BaLLatris [955]

In this question, it is given that the diagonal of the board is 18 inches long and one side of the board is 12 inches long.

Let the other side is of length b inches .

Now we use pythagorean identity, which is

a^2 + b ^2 = c^2

Here, a = 12 and c=18

Substituting these values, we will get

12^2 + b^2 = 18^2 \\ 144 + b ^2 = 324 \\ b^2 = 324-144 \\ b^2 = 180 \\ b= \sqrt{180} \\ b = 13.4164 inches

And the formula of perimeter is

Perimeter = 2(Sum\ of \ legs)

Substituting the values of the two legs, we will get

Perimeter = 2(12+13.4164) = 50.83 inches

You want to buy an MP3 player. Your Aunt paid you $20 to mow her lawn and you earn $5 each week
natka813 [3]

Answer:

1. y = 5x + 20

2. $20 the amount you saved mowing your aunt's lawn.

3. 21 weeks

Step-by-step explanation:

1. 5 is the slope because it is the rate. 20 is the y-intercept because that is how much you already have.

2. 20 because that is how much you already have.

3. Since you already have $20, you need to subtract 125 by 20 to get 105. Then you divide 105 by 5 to get 21 weeks.
