Answer:
r=sqrt(v/(pi*h))
Step-by-step explanation:
v=pi*r^2*h
divide by pi and h
r^2=v/(pi*h)
square root
r=sqrt(v/(pi*h))
Answer:
P(hit)=0.4
Step-by-step explanation:
In his practice, his probability of getting a hit was 6/15 or 0.4. This counts as an experiment, so the probability of him getting a hit again is the same, 0.4.
To solve this problem, you can create a system of equations and solve for each hiker's distance walked.
Hiker 1 distance walked: x
Hiker 2 distance walked: y
Their combined distance walked is 53 miles, thus -
x + y = 53
The difference between miles walked is 25, thus -
x - 25 = y
Let's solve using substitution. To do that, substitute x - 23 into x + y = 53 for y.
x + y = 53
x + (x - 25) = 53
x + x - 25 = 53
2x - 25 = 53
2x = 78
x = 39
To find y, substitute 39 for x into either of the equations.
x + y = 53
39 + y = 53
y = 14
Finally, check all work.
x + y = 53
39 + 14 = 53
53 = 53
x - 25 = y
39 - 25 = 14
14 = 14
Answer:
One hiker walked 39 miles and the other hiker walked 14 miles.
