area of rectangle = L x w
so 16 x12 = 192 square feet
To answer this problem you have to use a ratio, if it begins with 8:500, multiply 40 or 20,000/500 on both sides to get 320:20,000
9514 1404 393
Answer:
(B) 1/27
Step-by-step explanation:
The terms of the sequence have a common ratio.
(1/8)/(3/16) = (2/16)/(3/16) = 2/3
(1/12)/(1/8) = (2/24)/(3/24) = 2/3
(1/18)/(1/12) = 12/18 = 2/3
The next term will be ...
(1/18)(2/3) = 2/54 = 1/27 . . . . matches choice B
Answer:
~ 7m-20
Explanation:
~ First, we need to look at like terms and collect them. Like terms are similar numbers like all the m’s can be collected together.
~ Let’s count the number of m’s first. M+m+m+2m+2m should give you 7m.
~ Now lets just count the rest of the numbers: 15+15-30-20. 15+15=30, 30-30=0 and 0-20=-20.
~ Hence you get the answer of 7m-20
