kogti [31]

Answer:

8%

Step-by-step explanation:

APR means annual percentage rate.

To convert the daily rate to an APR, multiply the daily rate by the number of days in a year

365 days = 1 year

0.02192% x 365 = 8.0008%

To round off to the nearest percent, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

The tenth digit is 0, so the number would be rounded off to 8%

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test.
weqwewe [10]

9514 1404 393

Answer:

  (c)  Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Step-by-step explanation:

Try the numbers in the constraints to see if they work.

<u>Build hours</u>:

  (4 h/child bike)(10 child bikes) = 40 hours

  (6 h/adult bike)(12 adult bikes) = 72 hours

  total build hours: 40 +72 = 112, less than 120; constraint is met

<u>Test hours</u>:

  (4 h/child bike)(10 child bikes) = 40 hours

  (4 h/adult bike)(12 adult bikes) = 48 hours

  total test hours: 40 +48 = 88, less than 100; constraint is met

__

Both constraints are met, so the order can be filled.
