h = -4.9t^2 + vt
In our problem,
v = 12
t = 2
Let's plug our numbers into the equation.
h = -4.9(2)^2 + (12)(2)
h = -19.6 + 24
h = 4.4 m
Answer:
D
Step-by-step explanation:
Call the first person A who can do the job in 5 hours.
Call the second person B who can do the job in 7 hours.
The formula for this problem is
Time = A*B/(A + B)
Time = 5*7 / (5 + 7)
Time = 35 / 12
Time = 2 hours and 11/12 of an hour.
The answer is D.
Given:
A committee of 6 members is to be chose from the 100 members of the U.S. senate.
To find:
The number of ways to form a committee.
Solution:
We have,
Total number of members = 100
Number of members needs to selected of committee = 6
Number of ways to select r items from total n items is
Number of ways to select 6 members from total 100 members is
Therefore, the total number of ways to form a committee is 
, i.e., equal to 
.
Hello from MrBillDoesMath!
Answer:
7.7 % (approximately)
Discussion:
65 * x% = 65 * (x/100) = 5 => (multiply both sides by 100)
65 *( x/100)* 100 = 5 * 100 =>
65x = 500 =>
x = 500/65 = 7.7 (approx)
