Part a: ten books. because 3.75 equals 15/4 or 30/8. 10 3/8's fit into 30/8, so 10 books
part b: do basically the same thing and you will get 14 books though
Since we are dealing with volume, when one object is 4 times bigger than another, the difference in volume is 4^3 = 64.
6 cm sphere = 4/3 *PI * 6^3
6 cm sphere = 4/3 *PI * 216
6 cm sphere =

904.78 cc
24 cm sphere = </span></span></span>4/3 *PI * 24^3
24 cm sphere = 4/3 *PI * 13,824
24 cm sphere =

Comparing the volumes: <span>57,905.84 / 904.78 = </span><span><span><span>64

Answer:
The time it took until 2 inches of rain fell is 8 hours
Step-by-step explanation:
You know that the proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) it had fallen, y, is y = 0.25*x
To find the time that passed until 2 inches of rain fell, you must replace the amount of rain (in inches) that had fallen "and" by that value. In this way the following expression is obtained:
2= 0.25*x
Solving:
8 = x
So, remembering that the amount of time it had been raining, x, is expressed in hours, <u><em>the time it took until 2 inches of rain fell is 8 hours</em></u>.
Answer:
2520ft
Step-by-step explanation:
Calculation for what is the scale of the model?
Let x will be the span length
Hence,
x= 4200 feet long/20 inches long
x=210
Thus:
1 inch = 210 ft
1 ft = 2520
=2520ft
Therefore the scale of the model will be 2520ft
14 times 6 is 84, sorry if I didn’t understand your question
