Answer:
The average increase in the number of smart
phones per year is 45
Step-by-step explanation:
Given that :
Number of students who had phones in 2005 = 120
Number of students who had phones in 2010 = 345
(345 - 120) / 5
225 / 5
= 45
Hence, average increase in number of smartphones per year = 45
The answer is 1 mile an hour
Answer:
Step-by-step explanation:
no ,x*x*x*x*x=x^5
x+x+x+x+x=5x
in multiplication those who have same base we add their power.
in addition those variables which have same base(or are like term) we add them.
Answer:
5=67
Step-by-step explanation:
54÷0=2×4=567
=44+4=667÷6
The formula for calculating volume of the cylinder is
V= B * H
First volume V1= B * H1 and second volume V2= B * H2
H1= 2 H2
when we divide V2/V1 = (B*H2)/(B*H1) => when we shorten B and B we get
V2/V1 = H2 / H1 when we replace H1 we get V2/V1 = H2/ 2H2
when we shorten H2 and H2 we get V2/V1 = 1/2
The correct answer is the volume of the second cylinder is one-half the volume of the first cylinder.
Good luck!!!
