The first thing to do is find the rectangular warehouse area.
We have then:
A = (12) * (18) = 216
A = 216 m ^ 2
We now look for the area of each acoustic tile square:
A '= (1) ^ 2 = 1
A '= 1 m ^ 2
We look for acoustic tile squares number:
N = (A) / (A ')
N = (216) / (1)
N = 216
Finally we look for the total weight:
W = (1/4) * (216)
W = 54 Kg
Answer:
The total weight of the tile required to cover the ceiling is:
W = 54 Kg
Aftershocks occur after the most major part of an earth quake happens. Earthquakes occur at fault lines near the tectonic border. They occur because of the sudden movement for staying rigid while they were edging closer and closer. So the sudden movement releases a large amount of tension buried deep below the earth creating or resulting in an earthquake.
Answer:
$11.47
Step-by-step explanation:
In order to calculate Mrs.Jackson's total we first need to turn the fractions into decimals by simply dividing the numerator by the denominators like so...
2/3 = 0.66
1 1/4 = 1.25
1/2 = 0.50
Now we need to multiply each products cost by the amount they bought in decimal form, then finally add them all together...
($0.51 * 0.66) + ($2 * 1.25) + ($4.50 * 0.50) + ($3.19 * 2) = x
0.34 + 2.5 + 2.25 + 6.38 = x
$11.47 = x
Finally, we can see that Mrs. Jackson's total was $11.47
So 5 1/2 pages in 12 minutes
rewrite as eleven/2
Make a proportion
pages over minutes = pages over minutes
in an hour, there are 60 minutes
11/2 / 12 = x / 60
cross multiply
(11/2 * 60) = 12x
330 = 12x
divide both sides by 12
27.5 = x
She will read 27.5 pages in an hour.
How many pages in 3 hours?
that is 60 * 3 minutes
180 minutes
Use the proportion of pages/minutes = pages/minutes
plug in what you are given
<span>11/2 / 12 = x / 180
Cross multiply
(11/2 * 180) = 12x
990 = 12x
divide both sides by 12
82.5 = x
She will read 82.5, or 82 1/2, pages in 3 hours (or 180 minutes ;) )
Hope this helps </span>
