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% .

Bernice paid $162 in interest on a loan if $1,800 borrowed at 6%. How long did it take her to pay off the loan?
Wittaler [7]

Answer:

1.5 years.

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

t = 162 / ( 1800 × 0.06 ) = 1.5

t = 1.5 years

The time required to

accumulate simple interest of $ 162.00

from a principal of $ 1,800.00

at an interest rate of 6% per year

is 1.5 years (about 1 years 6 months).

How would you solve this
inn [45]

Answer:

x = 18.125

Step-by-step explanation:

58 + (5x+10) + ((11x + 2)-180) = 180

5x+10 + ((11x + 2)-180) = 122

5x + (11x + 2) - 180 = 112

5x + 11x + 2 = 292

16x = 290

x = 18.125
