What is the percent of change in 6 yards to 36 yards
BaLLatris [955]

Answer:

The percent of change in 6 yards to 36 yards is 500% .

Step-by-step explanation:

Formula

Percentage = \frac{Change\ in\ value\times 100}{initial\ value}

Where

Change in value = Final value - initial value

As given

The percent of change in 6 yards to 36 yards.

Final value = 36 yards

initial value = 6 yards

Change in value = 36 - 6

                           = 30 yards

Put in the formula

Percentage = \frac{30\times 100}{6}

Percentage = \frac{3000}{6}

Percentage = 500%

Therefore the percent of change in 6 yards to 36 yards is 500% .

I am Lyosha [343]

Answer:

x = 14

Step-by-step explanation:

The 2 given angles are vertical angles abd are congruent, so

4x - 22 = x + 20 ( subtract x from both sides )

3x - 22 = 20 ( add 22 to both sides )

3x = 42 ( divide both sides by 3 )

x = 14

Then

x + 20 = 14 + 20 = 34°

4x - 22 = 4(14) - 22 = 56 - 22 = 34°
