Samuel is looking at the floor plan of his house to determine how much carpet he needs to buy for his basement. Based on the flo
DerKrebs [107]

Answer:

B) First, find two areas using (4m x 10m = 40m2) and (8m x 3m = 24m2). Next, add (40m2 + 24m2 = 64m2).

Step-by-step explanation:

Samuel should is looking to find the area of his basement in order to cover it with carpet.

An area is calculated by multiplying two dimensions (so answers A and D are not it).

Best solution is to divide the area into two large rectangles then ADD them together to get the total area.

The only scenario where he could have subtracted something based on his plan is if he would have multiplied the 10m by the 12m then subtracted the area that is not part of his basement (7mx8m).  He would have achieved the same result of course, but by going a different way.

Colt1911 [192]
She needs in total 40,000 votes, and from those 40,000, 4/5 need to be from senior citizens, now, 5/5 is a "whole", so 5/5 - 4/5 that leaves only 1/5.

therefore, of those 40,000 votes, 1/5 can be of non-senior citizens, how much is 1/5 of 40,000?  well, is just their product,

\bf \cfrac{1}{5}\cdot 40000\implies \cfrac{40000}{5}\implies 8000
