Step-by-step explanation:
For finding range we will arrange it from least to greatest
0.50 1 1 1 1 2.50 2.50 3 4
So range = 4 - 0.50 = 3.50
Answer:
Let pork chops and ground beef be x and y respectively.
4x = $12.60
x = $3.15
11x = $34.65
5y = $10.25
y = $2.05
12y = $24.60
11x + 12y = $34.65 + $24.60
= $59.25
Answer:
40/13 hours
Step-by-step explanation:
Let 1 represent the room being painted.
1/5 would represent 1/5 of a room painted in 1 hour.
1/8 would represent 1/8 of a room being painted in 1 hour
But they are are working together so
(1/5)x + (1/8)x = 1
The lowest common denominator is 5 * 8 = 40
[(1/5)x * 40 + (1/8)x * 40] = 1
8x + 5x = 40
13x = 40
x = 40/13
x = 3.077 hours
But you want a fraction as your answer so it is 3 1/13 or 40/13
You should notice that 3.077 is smaller than the lowest amount of time both of them use. That always happens with these questions.
Milo owns 27 action-adventure DVDs.
45 (total) x 0.4 (% of comedies) = 18 (# of comedy DVDs).
45 - 18 = 27 (# of action-adventure DVDs)
Or
100 (total %) - 40 (% of comedies) = 60 (% of action-adventures)
45 (total) x 0.6 (% of action-adventure DVDs) = 27 (# of action-adventure DVDs)
