Answer:
Step-by-step explanation:
The computation of the number of weeks taken for empty the lake is shown below:
Given that
Lake empty in 6 weeks
The River could fill the lake in 20 weeks
Let us assume the combined lake be x
So, here the equation is
After solving this
x =
hence the number of weeks that take for empty the lake is
False. The answer should be between 8 and 16 because 5/3 = 1 2/3 which is between 1 & 2
So the product is between. 1 x 8 and 2 x 8

Answer:
V ≈ 154.1 in³
Step-by-step explanation:
Use the formula for the volume of a cone:
V = (1/3)πr²h
V = (1/3)π(4.4 in)²(7.6 in) ≈ 49.045π in³
V ≈ 154.1 in³

<em>Additional comment</em>
If you use 3.14 for π, your result will be 154.0 in³.
To construct the equations for these lines, we are going to use the point-slope formula, which is:
- is the slope of the line
- is a point on the line
1)
In this case, our point is (2, -1) and our line has a slope of 5. (Remember that the line is parallel, meaning that it has the same slope as the given line. Since the line is in the y = mx + b format, we could easily pick out the slope m as being 5.)
Thus, we can "plug in" what we know into our formula to find the equation of our line:
2)
We are going to do the same thing, except our point is now (0, -5) and our slope is now 9.
Our equations are:
1) y = 5x - 11
2) y = 9x - 5
<span>-x+12=3(4x+8)+1
- x + 12 = 12x + 24 +1
13x= 12-25
13x = - 13
x = - 1
Answer is A. {-1}</span>
