Answer:
1) 20%
2) Choice a.
Step-by-step explanation:
1) 
is the population initially.
is the population after a year.
represents the population increase factor.
So let's evaluate that fraction:
0.2=20%
2) Let's figure out the population growth in terms of months instead of years.
We want t to represent months.
A full year is 12 months, in a full year we have that 
So we want a new P such that 
since 12 months equals a year.
Let's look at the functions given to see which gives us this:
a) 
b) 
c) 
d) 
So a is the function we want.
Also another way to look at this:
where 
is in years.
where is in months.
And 
Answer:
m=-3
Step-by-step explanation:
10=7-m
m=7-10=-3
Answer:
Jocelyn's plane travelled 3650 miles.
Step-by-step explanation:
mph stands for miles per hour.
Let's set up an equation.
total miles = speed(hours)
Jocelyn's plane travelled 500 mph for 7.3 hours.
total miles = 500(7.3)
Multiply.
total miles = 3650
Jocelyn's plane travelled 3650 miles.
Hope this helps!
6km is 3/4 of her morning speed so 6/(3/4)=6×4/3=8km. Total distance=6+8=14km.
So find how much was eaten
1/6 and 2/3=eaten
add 1/6 and 2/3
convert bottom number to same
2/3=4/6
1/6+4/6=5/6
5/6 eaten
3-5/6=
2+1-5/6=
2+6/6-5/6=
2+1/6
2 and 1/6 waffles left
