Answer:

Step-by-step explanation:

Set up an equation, where x is the number of gallons of 60% antifreeze solution.

Represent the percentages of antifreeze with decimal values.

0.6x + 0.3(80) = 0.5(x + 80)

Simplify and solve for x:

0.6x + 24 = 0.5x + 40

0.1x = 16

x = 160

So, you have to mix 160 gallons of a 60% antifreeze solution

Jamie has a piece of wood that is 6/8 inches long. He cuts the wood into pieces that are ¼ inches long. How many pieces of wood
pashok25 [27]
Answer: three pieces.

The piece of wood is 6/8 inches long - this fraction can be simplified to 3/4 by dividing both the numerator and denominator by 2.

Thus, he cuts a piece of wood that is 3/4 inches long into 1/4 inch pieces.

1 goes into 3 three times, so the piece of wood can be cut into three 1/4-inch pieces.

kotegsom [21]

First let us calculate the total cost before tax:

1.06 * cost = 16.43

cost = 15.5

 

Therefore the cost of sunscreen is:

2 * Sunscreen + 6.50 = 15.5

2 * Sunscreen = 9

Sunscreen = $4.50

 

<span>Hence each bottle of sunscreen cost $4.50</span>

Find the area of the sector
sergij07 [2.7K]

Answer:

\boxed {\boxed {\sf a \approx 190.9 \ yd^2}}

Step-by-step explanation:

There are 2 formulas for the area of a sector, but since we are given the central angle in degrees (not radians), we will use this formula:

a= \frac {\theta}{360} \times \pi r^2

Where θ is the central angle and r is the radius.

For this circle, the radius is 9 yards and the central angle is 270 degrees. We can substitute these values into the formula.

a= \frac {270}{360} \times \pi \times (9 \ yd )^2

Solve the fraction.

a=0.75 \times \pi \times (9 \ yd)^2

Solve the exponent.

  • (9 yd)²= 9 yd* 9 yd=81 yd²

a= 0.75 \times \pi \times 81 \ yd^2

Multiply all three numbers together.

a= 190.851753706 \ yd^2

The question asks us to round to the nearest tenth.

  • 190.8<u>5</u>1753706

The 5 in the hundredth place tells us to round the 8 up to a 9.

a \approx 190.9 \ yd^2

The area of the sector is approximately <u>190.9 square yards. </u>
