Answer:

z = \sqrt{117}

Step-by-step explanation:

find 'y' first by using the altitude rule:

y/4 = 9/y

cross-multiply:

y² = 4(9)

y² = 36

y = \sqrt{36} = 6

Find 'z' by using the Pythagorean Theorem with legs equal to 6 and 9

6² + 9² = z²

36 + 81 = z²

117 = z²

z = \sqrt{117}

givi [52]

Answer:

Step-by-step explanation:

Convert mixed fraction to improper fraction. Then use KCF method

Keep the first fraction.

Change the division operation to multiplication.

Flip the second fraction

5\frac{1}{5}=\frac{26}{5}

5\frac{1}{5} ÷ \frac{1}{4}  = \frac{26}{5} ÷ \frac{1}{4}

          = \frac{26}{5}*\frac{4}{1}\\\\= \frac{26*4}{5}\\\\=\frac{104}{5}\\\\=20\frac{4}{5}

What’s the answer for this one??
KIM [24]

Answer:

It is the second one.

Step-by-step explanation:

a and e are equal because they are mirrored. d and b are equal because they are on the same  line and at the same point where the parallel lines go through. b and f are also mirrored. That leaves c and e which don't match.
