100%
Step-by-step explanation:
I got this wrong and i clicked until i got %100 try it:O)
Power functions are not linear, therefore B,D,F are the answers
1/9 + 1/2 = 1/x
Let x = length of time it will take both hoses to work together
Multiply both sides by 18x.
2x + 9x = 18
10x = 18
x = 18/10
x = 9/5
x = 1.8 hours
In other words, if both hoses work together, the pool can be filled in 1 hour and 48 minutes.
Answer:
The dog's running area is approximately 942 feet².
Step-by-step explanation:
The dog is leashed to a fixed point, the leash has a length of 20 ft, therefore he can rotate around that point at the maximum distance equal to the length of the leash. This pattern forms a circle, but there is an obstruction, which is the corner of the house. This obstruction takes an arc of the original circle, so the running area of the dog is the area of the whole circle minus the area of the arc formed by the corner of the house.

The dog's running area is approximately 942 feet².
88cm^2. area is the coverage of the area inside of a given shape, since some of the frame is cut off for a picture (making it not a full rectangle) you must find the area of the whole frame and find the area of the cutout. after finding those, subtract the cutout from the frame and then you have the area of the frame
