your answer should be D because you have to multiply 3.14 times 21 times 7 to get 461.58
I think it's 45 because 50+85=135
*Remember in total the sum of all angles must be equal to 180
So in order to find the missing angle subtract 180-135=45.
45 is the measure of the 3rd angle.
Hope I helped :)
Answer:
f(x)=1/4x-3
Step-by-step explanation:
y=mx+b
y-intercept is -3
-3=b
rise over round to find the slope
up 1 over 4
m=1/4
Area of 1 exam room = 10 ft. × 10 ft. = 100 ft.²
Area of 10 exam room = 100 ft.² × 10 = 1000 ft.²
Area of waiting room = 20 ft. × 15 ft. = 300 ft.²
Area of office area = 25 ft. × 20 ft. = 500 ft.²
Now,
Total area of the hospital to be replaced = 1000 ft.² + 300 ft.² + 500 ft.² = 1800 ft.²
