Taminka received a raise in her hourly pay, from $13.50 to $14.99. Find the percent change. Round to the nearest percent.
polet [3.4K]

Answer:

\% = 11\%

Step-by-step explanation:

Given

Initial = \$13.50

Final = \$14.99

Required

Determine the percentage change

This is calculated as:

\% = |\frac{Initial - Final}{Initial} * 100\%

\% = |\frac{13.50 - 14.99}{13.50}| * 100\%

\% = |\frac{-1.49}{13.50}| * 100\%

\% = \frac{1.49}{13.50} * 100\%

\% = \frac{1.49* 100\%}{13.50}

\% = \frac{149\%}{13.50}

\% = 11.037037037\%

\% = 11\%

4t+6s=4524
t+s=925

Multiply the second equation by -4 to cancel the variable t
4t+6s=4524
-4t-4s=-3700
2s = 824
Divide both sides by 2
S= 412

925-412= 513
T=513

The radius of a. circular garden is 15 feet. About how much fencing will be needed to enclose the garden?
WINSTONCH [101]

Answer:

94.2 ft of fencing

Step-by-step explanation:

To answer this, find the circumference, C, of the garden, using the circumference formula C = 2(pi)r.

Here, with r = 15 ft, we get C = 2(3.14)(15 ft) = 94.2 ft of fencing will enclose this garden.

Riverdale High ordered 84 shirts with their logo on them. if 8 of the shirts were defective what percent of the shirts were not
Ymorist [56]

8 were defective.

Defective percent = 8/84 x 100 = 9.5238% were defective.

Percent not defective = 100% - 9.5238% = 90.4761%

Rounding to the nearest tenth 90.5% were not defective.

The question doesn’t say how to round the answer so you may need to round differently than I did.
