You have to make the denominators(bottom of the fraction) the same in order to combine the fractions.
To make the denominator of 
the same as 
, you multiply the top and bottom of the fraction by 2 (because they both have a common multiple of 4)
So:
The same way.

Answer:
22π
Step-by-step explanation:
The area formula for a sector is
The angle theta is to be the angle that is a part of the sector for which we are trying to find the area. If we are looking for the area of the larger sector, we are not using 140 as our angle theta, we are using 360 - 140 = 220 as our angle theta since that is the angle for the larger of the 2 sectors. Filling in our formula using r = 6:
The easiest way to handle this math is to multiply the 220 by the 36, hit enter on your calculator, then divide that product by 360. When you do that your answer, in terms of pi, is 22π
Answer:
18k
Step-by-step explanation:
did math on this a few weeks ago
First, determine the width of the court by dividing the area by the length.
width = area / length
width = 162 m²/18 m = 9 m
Then, determine the perimeter of the court by the equation
P = 2L + 2W
where L and W are length and width, respectively.
P = 2(18m) + 2(9m) = 54 m
Given that every 20 m roll of tape costs $2.79, and even if the court is only 54 m, Jeff still needs to buy 3 20-m roll
total cost = ($2.79) x 3 = $8.37
Thus, the answer is letter B.
