a^2 = 47.5^2 + 27^2

a^2 = 2985.25

a = 54.637 = 55 inches

Circles M and K are congruent, QR is congrent to LN. Find the length of QR
Novosadov [1.4K]

Given QR is congrent to LN and QR = 4x + 2 and LN = x + 7.

So, QR = LN

Hence, we can set up an equation as following:

4x + 2 = x + 7

4x + 2 - x = x + 7 - x Subtract x from each sides.

3x + 2 = 7 By simplifying.

3x + 2 - 2 = 7 - 2 Subtract 2 from each sides.

3x = 5

\frac{3x}{3} =\frac{5}{3} Divide each sides by 3 to isolate x.

So, x=\frac{5}{3}

Next step is to plug in x=\frac{5}{3} in QR = 4x+2 to get length of QR.

So, QR = 4(\frac{5}{3})+2

=(\frac{20}{3})+\frac{2}{1} Since 2 can be written as 2/1.

By multiplying the second fraction by the common denominator 3.

=(\frac{20}{3})+\frac{2*3}{1*3}

=(\frac{20}{3})+\frac{6}{3} By simplifying the second fraction.

=(\frac{26}{3})

So, QR=\frac{26}{3}

A serving size for pineapple-orange punch is 1/2 cup. Liam needs to make 72 servings of punch. He will use 8 pints of pineapple
Hunter-Best [27]
Since a serving is 1/2 cup and he needs 72 servings you can multiply 72 by 1/2 and find out that he needs to make 36 cups of punch. Two cups is a pint so he needs (36 / 2) 18 pints of juice. He already has the 8 pints of pineapple juice so 18 - 8 leaves 10 pints of orange juice.
