Answer:
20,365.7 seconds
Step-by-step explanation:
First, we need to know how to convert yards to miles, as the question is in miles. We know that 1 mile is equivalent to 1760 yards. So we have:
1 mi = 1760 yards
If we multiply both sides by 81:
81 mi = 142,560 yards
And we know that the sprinter needs 8 second to run 56 yards:
8 s = 56 yards
If we divide both sides by 56 we get the time he needs for 1 yard:
8/56 s = 56/56 yards
1/7 s = 1 yard
So, takes him 1/7 seconds to run one yard. At this rate he runs 142,560 yards in:
(1/7) * 142,560 = 20,365.7
So, he needs 20,365.7 seconds to run 81 miles (142,560 yards)
Answer:
22.459 pounds of wood
Step-by-step explanation:
Total amount of wood in store = amount of pine wood purchased + amount of cedar in the store
Total amount of wood in store = 13.145 pine wood + 16.903 cedar wood
Total amount of wood in store = 30.048 pounds of wood
If acme lumber had sold 7.589 pounds of lumber after 6 months, the amount of pounds of woods that the company have left to sell = Total amount in store initially - amount sold after 6 months
Amount of pounds of woods that the company have left to sell = 30.048 - 7.589
The amount of pounds of woods that the company have left to sell = 22.459 pounds of wood
