The answer would be 2 times whatever the value of x would be
A circular plot is watered by a sprinkler that rotates through it. The sprinkler only rotates through a semi-circle, or half of the whole circle.
Area of a circle: A = pi x r^2
r = 160 / 2 = 80
A = pi x 80^2
A = 6400pi / 2 = 3200pi
3200pi = 10053.0965
The area water is approximately 10,053 ft^2.
Hope this helps!! :)
Answer: Uhm 1/3?
Step-by-step explanation: Maybe its not the answer i guess 11/3
Call x the number of foreign stamps and y the number of local stamps.
We write equations:
x+y=80
2x/3=y-10
Adding ten to the last equation, we have:
y=2x/3+10
Substituting this for y in the first equation, we have:
5x/3+10=80
Subtracting ten, we have:
5x/3=70
Multiplying by 3/5, we see that x=42, and y=80-42=38, so there are 42 foreign stamps and 38 local stamps.
22. Hope you get it right!
