To properly make the comparison between the weights of the books, we compute for their weights in similar units. For this item, we need to convert the weight of the first book to kilogram.
conversion:
Book 1 : (7.49 lbs) x (0.4535924 kg / 1 lb) = 3.397 kg
Since the second book weights 3.91 kg, it is heavier than the encyclopedia. Subtracting the weight of the first book from the second one will give us an answer of 0.51 kg. Thus, the answer to this item is letter D.
Answer:
10.5 seconds.
Step-by-step explanation:
Remember that this is an estimate. It is meant for you to do in your head. It is not meant for Google or a calculator.
100 meters is 1/2 of 200 meters.
100 meters time is roughly 1/2 that for 200 meters.
21 seconds * 1/2 = 10.5 seconds.
If we had two of these they'd fit together to form a nice 5 by 7 by 8 rectangular prism, just like the last one.
So our area is (5)(7)(8)/2 = 35(4) = 140
