Answer:
69 pennies
Step-by-step explanation:
Below is the given data:
Pennies at the starting of February = 34
Pennies in 1st week of February = 13
Pennies in 2nd week of February = 9
Pennies in 3rd week of February = 6
Pennies in 4th week of February = 7
To find the number of pennies at the end of February just add all the pennies.
At the end of February, the number of pennies = 34 + 13 + 9 + 7 +6 = 69 pennies

Answer:
19.6 cubic centimeters
Step-by-step explanation:
The ratio of two similar 3D figures' volumes is equivalent to the ratio of their corresponding lengths (whether it's width, height, length, radius, etc) cubed.
Here, we know the cones are similar, and we know the smaller radius is 2 and the larger radius is 3. Then the ratio of the volume of the smaller one to the volume of the larger one is
.
We also know the actual volume of the larger cone is 66. So, if x is the volume of the smaller cone, we have the proportion:
x / 66 = 8 / 27
Cross-multiply:
27x = 66 * 8 = 528
Divide by 27:
x = 528/27 ≈ 19.6
The answer is thus 19.6 cubic centimeters.
