Step-by-step explanation:
Answer: 16,384
Step-by-step explanation:
The seven marbles have different colours, so we can differentiate them.
Now, suppose that for each marble we have a selection, where the selection is in which jar we put it.
For the first marble, we have 4 options ( we have 4 jars)
For the second marble, we have 4 options.
Same for the third, for the fourth, etc.
Now, the total number of combinations is equal to the product of the number of options for each selection.
We have 7 selections and 4 options for each selection, then the total number of combinations is:
C = 4^7 = 16,384
Answer:
40 1/2 inches
Step-by-step explanation:
Maddy, I think you meant your circumference (not circumstances) is 81π inches (not square inches).
C = 2πr, so:
81π in
r = ------------ = (81/2) inches, or 40 1/2 inches This is the radius.
2π
9+7x=37
7x=37-9
7x=28
x=28/7
x=4
