Question

1. Many airlines have limits on the size of carry-on baggage that a passenger may have. One airline's rule is that l + w + h must be less than 50 inches, where l is the length, w is the width, and h is the height of a bag. Will a bag with the following dimensions be allowed?

l = 20 inches

w = 18 inches

h = 11 inches

yes
no

2. The area of a parallelogram is found using the formula bh, where b represents the length of the base and h represents the length of the height. According to this formula, how can you find the area?

add the base and the height
multiply the base and the height
divide the height by the base
multiply two times the base

Answer 1

Explanation:

1. If l + w + h has to be less than 50, we can write this as l + w + h < 50. Now, we plug in 20 for l, 18 for w, and 11 for h. When we do so, we get 20+18+11<50 which simplifies to 49<50. Since 49 is in fact less than 50, it is a true statement, and therefore, the bag will be allowed.

2. bh can be rewritten as b*h, which is multiplication. This eliminates options 1 and 3. We know that it can't be the last one because we are not multiplying 2 and b. Therefore, it is the second option, multiply the base and the height. Hope this makes sense!
