Answer:
The answer to your question is the letter B. 27
Step-by-step explanation:
Data
The Radius of large sphere = 3 times the size of the radius small sphere.
The Ratio of Volume = ?
Formula
Volume of a sphere = 4/3 πr³
Process
1.- Calculate the volume of the large sphere
Vl = 4/3 π(3r)³
2.- Calculate the volume of the small sphere
Vs = 4/3 πr³
3.- Calculate the ratio
Vl / Vs = [4/3π(3r³)] / [4/3 πr³]
- Simplification
Vl / Vs = 3³r³ / r³
Vl / Vs = 27
Cmon this is easy it is 24 okay
4+1 = 5
5 is the answer but you could also just subtract it a normal way
Answer:
x = 4
y = 11
Step-by-step explanation:
Set your formula as follow:
2x+3=3x-1 -> 2x+3-3x=-1 -> -x+3 = -1 -> -x=-4 -> x=4
now substitute x for 4 in the following
y-2=2(4)+1 -> y-2=8+1 ->y-2 = 9y -> y=11
Kelvin would read 70 pages in 2 hours.
Step-by-step explanation:
Total pages read per hour by Kevin= 35 pages
Total number of hours in consideration= 2 hours
Hence total pages that are read by Kevin in 2 hours= Pages read in 1 hour * Total hours in consideration
Substituting the values of pages read by Kevin in 1 hour and total hours in consideration
Total number of pages= 35*2= 70 pages
Hence, the total number of pages read by Kevin in 2 hours is 70 pages
