It will take John 2800 steps to walk from his house to James' house
Step-by-step explanation:
First of all we have to convert all the measurements in same unit.
Distance = 0.7 km
As 1 km = 1000 m
0.7*100 = 700m
And
1 m = 100 cm
700*100 = 70000cm
Now,
25 cm = 1 step

55t+285t=1020 combine like terms on left side
340t=1020 divide both sides by 340
t=3 hours
However that t is for the amount of time spent on the train and the same amount of time spend on the plane. So the total time for the trip is 2 times t, which is:
6 hours.
Answer: 42 -12e
Step-by-step explanation: look at the image
The expression for finding the amount of money earned on interest is
where
P = principal (money you started with)
r = rate (in decimal form)
n = number of times compounded per year
t = time (in years)
In this case:
P = 3000
r = 0.02 (because 2% in decimal form is 0.02)
n = 1 (because it is compounded once every year)
t = 16 (because she got the money when she was 2 and we are calculating it for when she turns 18, 16 years later)
So, you plug it in:
So, the answer is (1) <span>3000(1 + 0.02)^16</span>
