The length of the rectangular tennis court at wimbledon is 6 feet longer than twice the width. if the court's perimeter is 240 f
KATRIN_1 [288]

Length (L): 2w + 6

width (w): w

Perimeter (P) = 2L + 2w

               240 = 2(2w + 6) + 2(w)

               240 = 4w + 12 + 2w

               240 = 6w + 12

               228 = 6w

                 38 = w

Length (L): 2w + 6   = 2(38) + 6   = 76 + 6   = 82

Answer: width = 38 ft, length = 82 ft

Determine the radius of a circle if a 24-inch chord is 9 inches from the center.
bixtya [17]
Hi! :)

The radius of a circle is the length from the perimeter of the circle to the center of the circle. 

If  24 inches is still 9 inches from the center, you just have to add 24 and 9 to get the radius. 

24+9= 33

Your final answer should be that the radius is 33 inches.

Hope this helps!

Sun, a kayaker, paddles 8 miles upstream (against the current) in 2 hours. Returning to her original location, she paddles downs
Virty [35]

Answer: a=8 and b=1


Step-by-step explanation:

If x represents the paddling speed, and y represents the speed of the current.

Then Relative speed in upstream =x-y

Relative time in downstream=x-y

When she paddles upstream then distance covered by her=speed\times\ time

⇒8=(x-y)2 or 2(x-y)=8

Thus we get, a=1

When she paddles downstream then distance covered by her=speed\times\ time

⇒8=(x+y)1 or 1(x+y)=8

Thus we get b=1
