Answer:
8.565
Step-by-step explanation:
Volume=4/3pir^3
3000m^3=4/3pir^3
3000/4/3=pir^3
25/pi=r^3
approx 78.539=r^3
r=4.2825
we know,
2r=d
d=2×4.2825
d=8.565
You can round the answer off yourself :3
4 x^2 + 20 x + 25 = 7
Divide both sides by 4:
x^2 + 5 x + 25/4 = 7/4
Write the left-hand side as a square:
(x + 5/2)^2 = 7/4
Take the square root of both sides:
x + 5/2 = sqrt(7)/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
x = sqrt(7)/2 - 5/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
Answer: x = sqrt(7)/2 - 5/2 or x = -5/2 - sqrt(7)/2
Answer:
517 minutes
Step-by-step explanation:
60 minutes per hour.
8 x 60 = 480
37 minutes, 480 + 37 = 517
