First, find the volumes of each figure.
Remember that the volume of a sphere =
Smaller sphere:
4188.79 Cubic inches.
Larger sphere:
33510.32 Cubic inches.
33510.32 - 4188.79 = 29321.53 cubic inches
Hope that helps!
Answer:
A: 68.25 minutes
B: 12 times
C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.
Step-by-step explanation:
a: 72 -0.75*5 = 68.25
b: M=63=72-0.75n
subtract 72 from each side: -9 = -0.75n
divide each side by -0.75: n = 12
so 12 times
c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.
Answer:
2, 120 degrees
Step-by-step explanation:
The first step in finding the polar form is finding the modulus, r
r= sqrt( x^2 + y^2)
r = sqrt( (-1)^2 + sqrt(3)^2)
r = sqrt(1+3)
r= sqrt(4)
r =2
The next step is finding the angle
theta = arctan (y/x)
theta = arctan (sqrt(3)/-1))
theta = arctan (-sqrt(3))
theta = -60
The point (-1, sqrt(3)) is in the 2nd quadrant, but our angle is in the 4th quadrant, so we add 180 degrees
theta = -60 + 180 = 120
theta = 120 degrees
Answer:
1:9
Step-by-step explanation:
6×60=360min
40:360
1:9
1/3 wins and 2/3 losses
given 2 and 5 = 2/6 = 1/3
1, 3, 4, and 6 = 4/6 = 2/3
