Answer:

Step-by-step explanation:

There are many ways to approach this problem. I like a method that uses the least amount of computation. We could figure how much Wendy makes on a bag of chips, the additional amount Wendy wants to make, then divide the latter by the former to find the number of additional bags to sell.

We could use a proportion to figure the number of bags corresponding to $126 in earnings, then subtract the 72 bags already sold. Essentially, we will do this, but without the intermediate numbers.

The additional fraction of 72 bags will be ...

(126/108) -1 = 18/108 = 1/6

Then Wendy must sell an additional ...

(1/6)×(72 bags) = 12 bags

to increase her earnings to $126.

Let
x---------------> long side rectangle------------> 13.5 in
y---------------> wide side rectangle------------> 10 in
d--------------> length of a diagonal

we know applying the Pythagorean theorem
d²=x²+y²-----------> d²=13.5²+10²-> d²=282.25
d=√282.25=16.80 in

the answer is 16.8 in

If a math student Square both legs of a right triangle and the results were 441 and 400, what is the length of the hypotenuse of

kolezko [41]

Answer:

$29 \\$

Solution:

According to the Pythagorean Theorem, is that the square of the hypotenuse is equal to the sums of squares of the two legs in which if you take the square root of the sum you are going to get the actual length of the hypotenuse but the two legs are already squared so all you have to do now is sum them and take the square root of it.

$\sqrt{441 + 400} \\ \sqrt{841} \\ 29$
