16ft= 192 in
8ft= 96 in
192/36= 96/16 = 6
Your drawing is 1/6 of the actual billboard
Percent decrease. 41%
percent change= (new-old)/old *100
= -41 % the negative means decreasing
A = {x ≥ 3}, B = {x ≤ 1}
So A∪B = {x ≥ 3 or x ≤ 1}
So for x ⊆(1,3), A∪B = ∅
Apparently, (1,3) covers the first option, a will be the answer
im not sure if it is right but i got 920 cm2. is that one of ur answers?
Simply put,
If you find a common denominator between 12 and 16, and multiply them to fit,
You should end up with a proportion giving you the correct answer. Whichever is lower is the better deal
Ex: a box of cereal from target costs $2
Two box deal from Costco costs $5
Which is cheaper for the money.
Assuming they are the same size, all you have to do is take the dollar amount from the one from target and multiply it by two, giving you the cost of two boxes.
$4<$5
