He would make more money with Susie than by himself because if he only works three hours and Susie make more money than him she would have more but if they work as a team they could split the money and get more together.
Now to solve this problem, all we have to remember is the
formula for calculating the linear speed given the radial speed, that is:
v = r w
where,
v = is the linear velocity or linear speed
r = is the radius of the circular disk = (1 / 2) diameter
= (1/ 2) (2.5 inches) = 1.25 inches
w = is the radial velocity (must be in rad per time) =
7200 rev per minute
Calculating for v:
v = 1.25 inches (7200 rev per minute) (2 π rad / 1 rev)
v = 56,548.67 inches / minute
Converting to miles per hour:
v = 56,548.67 inches / minute (1 mile / 63360 inches) (60
min / hour)
<span>v = 53.55 mile / hour</span>
Answer:
There are 924 possible combinations
Step-by-step explanation:
Total Number of marbles = 12
Number of marbles to be selected = 6
We are supposed to find the number of possible combinations .
So, we will use combination .
Formula: 
n = 12
r = 6
Substitute the values in the formula :
Hence there are 924 possible combinations
