Answer:
A. 821.5 Square Yards
Step-by-step explanation:
30 x 30= 900
900 is the area for the whole park
To find the pool area you need to do pi times Radius squared
so 3.14 x 5 x 5
That equals 78.5 for the pool area.
So to find the grass area you need to subtract the pool area from the park
900 - 78.5 = 821.5 square yards!
Answer:
Step-by-step explanation:
sin 30+tan²(60)+sec²(45)
=1/2+ (√3)^2+(√2)²
=1/2+3+2
=5 1/2
=5.5
558.7 , because 74 x 7.55 = 588.7 , it would be his total for the two weeks
The bisector of an angle of a triangle divides the opposite side into segments that are proportional to the adjacent sides
VT/TK = VY/YK
95.2/168 = 34/YK
YK = (168·34)/95.2 = 60 cm
x = VY + YK = 34 + 60 = 94 cm
If y varies directly as the square of x, that means that y=k*x^2. Plugging y=100 and x=5 into it, we get 100=k*5^2=k*25. Dividing by both sides, we get k=100/25=4. Going back to the original equation, we now know that y=4*x^2. Plugging 9=x in, we get 4*9^2=4*81=324=y
