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:
QT = 20 and QW = 30
Step-by-step explanation:
For triangle Δ PQR, the centroid is T and it is on one median is QW.
We know that the medians intersect each other at centroid and the centroid divides the medians in 2 : 1 ratio.
So, we can write
⇒ QT = 2 × TW = 2 × 10 = 20 (Answer)
{Since the length TW is given to be 10}
Now, QW = QT + TW = 20 + 10 = 30 (Answer)
-12 = x+5<=-4 -12+5=-7 so -7<-4 So the conclusion is that negative seven is less than negative four.
