Answer:
The rate of the runner is 3.5 meters per second.
Step-by-step explanation:
To get this answer in meters per second, we first have to convert each of the terms into either meters or seconds. We can do that by multiplying by unit rates.
21 km * 1000 = 21,000 meters
1 hour * 3600 = 3,600 seconds
40 minutes * 60 = 2,400 seconds
Now we divide the meters by the total number of seconds to get the rate.
21,000 meters / (3,600 + 2,400) secs
21,000 meters / 6,000 secs
3.5 meters per second.
Answer:
see below
Step-by-step explanation:
When you must do the same tedious calculation several times with different numbers, it is convenient to let a spreadsheet program do it for you. Here, the spreadsheet function PMT( ) computes the payment amount for the given interest rate, number of payments, and loan amount.
The loan amount is 90% of the purchase price.
The total interest over the life of the loan is the sum of the payments less the original loan amount.
The total monthly payment is the sum of the loan payment and the monthly escrow amount, which is 1/12 of the annual escrow amount.
_____
Here, we computed the total of payments using the unrounded "exact" value of each payment. We take this to be a better approximation of the total amount repaid, since the last payment always has an adjustment for any over- or under-payment due to rounding.
Multiply 80 by 14 to get how many total people they can feed.
80 times 14 is 1120.
Now, divide 1120 by 32 to get how many days the food will last if 32 people come every day.
1120/32 = 35.
The answer is B, 35 days
Answer:
5 days

Step-by-step explanation:
65/7=9.28571429
9.28571429 sec = 1 dollar
464285.715 seconds=50000 dollars
464285.715 seconds=5.373677256944 days
Answer:
