The area of a sector is 339.336 cm²

The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.

It can be determined by using the formula:

\mathbf{A = \dfrac{\theta }{360}\times \pi r^2 }

Given that;

  • Radius r = 18 cm
  • Angle θ =  120°

Then. the area of the sector can be calculated as:

\mathbf{A = \dfrac{120}{360}\times \pi (18)^2 }

\mathbf{A = \dfrac{1}{3}\times 3.142 \times 324 }

A = 339.336 cm²

Paul finished his 800 meter race in 2 minutes and 2 seconds. Jeff finished in 121 seconds. Who finished first? (PLESES SHOW WORK
elixir [45]

Answer:

Jeff finished first

Step-by-step explanation:

To solve this equation, I can either converts 2 minutes 2 seconds to seconds or convert 121 seconds to minutes

<u><em>CONVERT 2 MINUTES 2 SECONDS TO SECONDS</em></u>

60 seconds = 1 minutes

to convert 2 minutes 2 seconds to seconds, multiply 2 minutes by 60 and then add 2 seconds to it

2 x 60 = 120 seconds

120 seconds + 2 seconds = 122 seconds

Paul finished in 122 seconds while Jeff finished in 121 seconds. Jeff finished first

<u><em>CONVERT 121 SECONDS TO MINUTES</em></u>

60 seconds = 1 minutes

To convert 121 seconds to minutes, we have to divide by 60

121/60 = 2 minutes 1 second

Paul finished the race in 2 minutes 2 seconds while eff finished the race in 2 minutes 1 second. Jeff finished first

A grocer bought n eggs at $x each. He marked up the price of each egg by $y and sold all of them. Find the sales amount, express
Alex777 [14]

Answer:

Sales = n \times ($x + $y)

Step-by-step explanation:

The basic simple sales equation is

Quantity \times Price = Sales

Here in the given question,

Total quantity of sales = n

Price = Cost + markup

(Markup refers to the profit added to cost)

Thus price = $x (cost) + $y (markup)

Sales = n \times ($x + $y)

Sales amount is the total amount received from sales of products, total quantity at some price provided.
