Answer:
19.9 miles
Step-by-step explanation:
In this problem we have:
is the distance travelled during the 1st day
is the distance travelled during the 2nd day
is the distance travelled during the 3rd day
is the distance travelled during the 4th day
We notice that the difference between the distance travelled on the (n+1)-th day and the distance travelled on the n-th day doubles every day. In fact:
Which can be rewritten using the general formula:
This means that
By applying this formula recursively, we can find the 7th term, which is the distance travelled on the 7th day:
So, the distance travelled on the 7th day is 19.9 miles.
Answer:
Sophia should start her homework at 5:55
Step-by-step explanation:
If it takes her 10 minutes to go to school, 30 minutes to do her homework, and 25 minutes to eat dinner, you should add those numbers together to get 65 because then you can subtract 65 minutes from 7:00 so you get the time she needs to start her homework in order to get to school at 7:00. So basically 10+30+25=65 and then 65 minutes subtracted from 7:00 is 5:55.
I hope this helps you :D
Answer:
$899.15
0.85(1199) - 120
Step-by-step explanation:
To find the purchase total, multiply the price by the percent paid and subtract the certificate.
The store offers a 15% discount. This means you pay 85% of the price. So the discounted price is 0.85(1199) = 1019.15
Subtract the certificate 1019.15 - 120 = 899.15
The composite function is 0.85(1199) - 120.
