1) we calculate the volume of the first carton:
volume=length x width x height
volume=3 ft * 2 ft * 2 ft=12 ft³
Therefore:
A machine can fill 12 ft³ in 3 seconds.
2) we calculate the volume of the second carton.
volume=length x width x heigth
volume=4 ft * 5 ft * 6 ft=120 ft³
3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.
12 ft³---------------------3 seconds
120 ft³-------------------- x
x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.
answer: 30 seconds.
Answer:
4.9
Step-by-step explanation:
Plug in 13 and 2 for each variable separately to get 0.7(13) - 2.1(2). 0.7 multiplied by 13 equals to 9.1 and 2.1 multiplied by 2 equals 4.2. Subtract 4.2 from 9.1 to get your final answer which is 4.9.
Answer:
$1,482 is the 10th percentile.
Step-by-step explanation:
xth percentile:
If a measure is said to be in the xth percentile, it means that x% of the measures are smaller than it, and (100-x)% are larger.
In this question:
10 computers, the 10th percentile is the value that is larger than 10% of the prices.
The prices, sorted in an increasing way, are:
$1,127, $1,482, ...
Computers at a price of $1,482 have larger prices than 10% of the population, so $1,482 is the 10th percentile.
10 is the answer because 10 times itself is equal to 100
