Answer:
20
Step-by-step explanation:
"Nine out of ten students prefer math class over lunch. How many students would not prefer math class if 200 students were asked about their preferences, if they followed the same percentage?"
Nine out of ten
Change total (ten) to 200
Ratio: 9/10 = x/200
180/200 = x/200
x = 180 prefer math
200 - 180 = 20 do not prefer math
Answer:
its c because b is a right angle triangle
thats how i solved it if there is a mistake tell me
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!! :)
