Step-by-step explanation:

We know the area of a circle is

\pi {r}^{2}

That is when the cricle is 360 degrees full, so another formula is

\frac{360}{360} \pi {r}^{2}

If we the find the area of the sector with angle x, then that formula will be

\frac{x}{360}  {\pi}r^{2}

Answer:

98.

Step-by-step explanation:

  • Parenthesis
  • Exponents
  • Multiplication
  • Division
  • Addition
  • Subtraction

You have to do it in order so you can get the correct answer. Do the problem in the parenthesis first. 6 ÷ 3 = 2.

It should look like this:

7² x 2.

Then, do your exponents. 7² is just basically 7 x 7. It equals 49.

Now, it should look like this:

49 x 2. Multiply 49 x 2, and your answer should be 98.

You need to buy some chicken for dinner tonight. You found an ad showing that the store across town has it on sale for $2.89 a p
ASHA 777 [7]

Answer:

   1. Going to the close store is cheaper.

Step-by-step explanation:

The difference in the prices of chicken is 3.19 -2.89 = 0.30 per pound, so for 5 pounds of chicken, the far store offers a price that totals 5×$0.30 = $1.50 less.

The difference in travel distances is 8.4 -2.4 = 6 miles, so the total round-trip distance difference is 12 miles. The cost of gas is ...

  ($3.81 /gal)/(23 mi/gal) = $0.1656 /mi

so the cost of gas for the 12-mile longer trip would be

  12×$0.1656 ≈ $1.99

Traveling to the far store, you would spend $1.99 more on gas to save $1.50 on the price of chicken. Going to the close store is cheaper.
