Answer:
-11
Step-by-step explanation:
Answer:
2m
Step-by-step explanation:
2 * 1.5 = 3, the total height
we know that there are three metres total and 1 is half the other, so we divide 3m by 3 = 1m, the height of B,
as A = 2B, A = 2m
Answer:
Step-by-step explanation:
The population of a community is known to increase at a rate proportional to the number of people present at time t.
This means that the population growth is modeled by the following differential equation:
Which has the following solution:
In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate.
The population has doubled in 10 years
This means that 
. We use this to find r.
So the equation that will estimate the population of the community in t years is:
Answer: A.4Runner cost more for $11.02
B.Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fuel for 4Runner : 6.818*3.59=$24.48
Step-by-step explanation:
A.Find how many gallons 4Runner spends on 150 mile trip.
use proportion
22:1=150:x
22x=150
x=150/22
x=6.818 gallons
Cost of fuel for 4Runner : 6.818*3.59=$24.48
Calculation for Elentra:
40:1=150:x
40x=150
x=150/40
x=3.75 gallons
Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fule for 4Runner-Cost of fuel for Elentra=24.48-13.46=$11.02
4Runner cost more for $11.02
B.Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fuel for 4Runner : 6.818*3.59=$24.48
Answer:
Step-by-step explanation:
y = x
The constant of proportionality is 1 although you cannot see it. It is understood to be there.
y = (-8/5) x
This is a nasty piece of work and it depends on your grade level. If you are below grade 8, you are not encouraged to think of a constant of proportionality as less than 0.
In general the opinion is split. Some people say yes others no. If you twist my arm and put a gun to my head, my answer would be that it's fine, but it is a matter of what you have been told. I would read your notes.
