Answer:
13 boxes
Step-by-step explanation:
To calculate the minimum number of boxes that can be had with that amount of paper, they should be kept in the largest box, that is, the 27 cubic foot box, therefore, we divide:
257/27 = 9.51
Which means that we can save the paper in 9 boxes of 27 cubic feet, now we will save the rest in the next smaller box, the 9 cubic foot box.
First let's calculate how many leftover paper:
257 - 27 * 9 = 14
Therefore, we can only use 1 box of 9 cubic feet:
14 - 9 = 5
For the remaining 5 cubic feet use 1 box of 3 cubic feet and 2 boxes of 1 cubic foot.
Therefore, in total it would be:
9 of 27 ft ^ 3 + 1 of 9 ft ^ 3 + 1 of 3 ft ^ 3 + 2 of 1 ft ^ 3 = 13
a total of 13 boxes would be the minimum
Answer:
1,500 lbs.
Step-by-step explanation:
1 Ton = 2,000 lbs.
2,000 * 0.75 = 1,500
1,500 lbs.
Subtract 4 from -17, from 3x+4, and from 19:
-21 < 3x < 15
Divide all terms by 3:
-7 < x < 5 (solution)
Answer:
$471.65
Step-by-step explanation:
-The value of the laptop after each year is calculated by the formula:
where:
is the value at time t
is the initial value
is the rate of depreciation
is the time
#We substitute the values to solve for the value after 3 years(2010-2007=3):
Hence, the value of the laptop in 2010 is $471.65
Answer: 12n-10= -58
+10. +10 (add to both sides)
12n. = -48
÷12. ÷12 (isolate variable)
n. = -4
