The inequality that represents people more than 3000
The given parameters show a geometric sequence and will be calculated using:
Where t is the number of days
For the people to be more than 3000, the expression becomes:
Substitute values for a and r
Divide both sides by 15
Take log of both sides
Apply law of logarithm
Make t - 1 the subject
Add 1 to both sides
Round down
Answer:
1.5 miles
Step-by-step explanation:
1.5 miles
Since there are 60 minutes in an hour, the person will walk 60/10 = 6 times as much in 1 hour. If that person can walk 1/4 mile in 10 minutes, she will walk (1/4)*6 = 1.5 miles in 1 hour.
7!/3!
7! = 7 X 6 X 5 X 4 X 3 ...
3! = 3 X 2 x 1
since the 3 X 2 X 1 part are repeated in both the numerator and denominator, we can divide them out
7!/3! = 7 X 6 X 5 X 4 = 42 X 20 = b. 840
