Answer:
Area_lawn = 393.75 π ft^2
Step-by-step explanation:
Maximum radius : 30 feet
Minimum radius: 30 feet - 0.25*(30feet) = 22.5 feet
(25 percent reduction)
To find the area of lawn that can be watered, we just need to calculate the area for the maximum radius and the minimum radius, and then subtract them.
Since the sprinklers have a circular area:
Area = π*radius^2
Max area = π*(30 ft)^2 = 900π ft^2
Min area = π*(22.5 ft)^2 = 506.25π ft^2
Maximum area of lawn that can be watered by the sprinkler:
Area_lawn = Max area - Min area = 900π ft^2 -506.25π ft^2
Area_lawn = 393.75 π ft^2
Answer x=-9/2. It’s period is times?? I might wrong

Answer:
No Solutions
Step-by-step explanation:
Let's find out.
-2(t-4)=10-2t
-2t+8=10-2t
-2t=2-2t
0=2
Hope this helps :)
The distributive property of 75/3 may look like:
75/3 = 30/3 + 30/3 + 15/3
It's easier to count 30/3 than 75/3, so I did it twice and then I had 15 left, because 75 - (30 + 30) = 15.
That's basicly how you do it - just try to find the easiest number to divide (smaller then the given dividend).
