Students in a 6th grade class are raising money for an end-of-year camping trip. So far, they have raised $240. This is 2/5 of the cost of the trip. How much does the trip cost?

 $600

Step-by-step explanation: well first this is my logic and is a little confusing but here. so first im gonna x2 240 bc if we do this then we are gonna change the fraction to 4/5, so its 480. then we have to fill 1/5 so we divide 240 into 2. because is an even number you can do that easly, its 120. then we are gonna add 120+480= 600 there we go.

Hope this helped :)

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
