Answer: 6,300 m^3
Step-by-step explanation:
Put numbers into calculator
You can't tell. The volume doesn't tell you the dimensions. It only tells you
what the product of the three dimensions is, but not what anyone of them is.
There are an infinite number of different possibilities.
Example: Volume = 8 cubic feet
The dimensions of the box could be
Length = 2-ft, Width = 2-ft, Height = 2-ft
or
1 x 1 x 8
or
1 x 2 x 4
or
1 x 3 x 2-2/3
or
1 x 5 x 1.6
or
1 x 6 x 1-1/3
or
1 x 7 x 1-1/7
or
2 x 3 x 1-1/3
or
2 x 5 x 0.8
or
2 x 6 x 2/3
or
2 x 7 x 4/7
or
2 x 8 x 1/2
.
.
etc.
<u>First problem :</u>
probability to draw a red paper : 42/(42+18)=7/10
In 110 tries one can thus expect to draw 7/10*110=77 red papers
<u>Second problem :</u>
Since for 150 trials (which will give the least error) we have got 135 yellow balls, we can expect twice as much in 300=150*2 trials, which makes 270 yellow balls.
<u>Solution</u><u> </u><u>:</u><u>-</u>
This triangle is a right angled triangle as we can see ∠POC, has a right angled sign. Now, we will assume the missing angle to be x, thus,
25° + 90° + x = 180° ( Angle sum property of a triangle )
115° + x = 180°
x = 180° - 115°
x = 65°
Thus, the measure of missing angle is 65°.
Hope that helps. :D
