a cylindrical tank with radius 7 m is being filled with water at a rate of 4 m3/min. how fast is the height of the water increasing?
Answer:
0.026 m / min.
Step-by-step explanation:
Volume V = π7^2h
V = 49πh
dV/dh = 49π
Rate that the volume is increasing is 4 m3/min.
So dV/dt = 4
dV/dt = dh/dt * dV/dh
4 = dh/dt * 49π
dh/dt = 4/49π
= 0.026 m / min.
The required height of the water increase is given as 0.026 m/min.
Given that,
A cylindrical tank with a radius of 7 m is being filled with water at a rate of 4 m3/min, how fast is the height of the water increasing is to be determined
Volume is defined as the ratio of the mass of an object to its density.
Here,
The volume of the cylinder =πr²h
Substitute the value in the above formula
Volume V = π7²h
V = 49πh
V/h = 49π - - - - - - - (1)
Rate of the filling the tank is given,
V/t = 4
V = 4t
Substitute this in equation 1
4t / h = 49π
h / t = 0.026 m/s.
Thus, the required height of the water increase is given as 0.026 m/min.

The ratio of hotdogs to hamburgers sold at the picnic was 3:4. If 98 dinners were sold, how many were hamburgers?
Answer:
56 Burgers
Step-by-step explanation:
First, add the 3 + 4 for a total of 7, because the total of the ratio will equal the total amount of "the dinners sold".
Then divide 98/7, which will give you 14.
Then in the ration 3:4, 4 represent burgers so multiply 14 x 4.
Which gives you 56 burgers.

If -13(q+4) is equal to 7q+16 what’s is q
Answer:
q = - 3.4
Step-by-step explanation:
- 13(q + 4) = 7q + 16 ← distribute parenthesis on left side
- 13q - 52 = 7q + 16 ( subtract 7q from both sides )
- 20q - 52 = 16 ( add 52 to both sides )
- 20q = 68 ( divide both sides by - 20 )
q = - 3.4

Answer:
18/24 or 75%
Step-by-step explanation:
Okay so you already know that he got 16/24 which means that there were 8 questions that were wrong because 24-16= 8
So he has 16 points that we know of and 8 questions that he got wrong.
If he lost 1/4 of a point when he got it incorrect 1/4= 0.25
0.25 x 8 = 2points
So he got to points
16+ 2= 18 so now it is 18/24
If you have to show Out for 100% it would be 75%

At HD Sport & Fitness gym, analysis shows that, as the demand of the gym, the number of members is 83 when annual membership fee is $17 per member and the number of members is 81 when annual membership fee is $24 per member. As the operator of the gym, you found out that number of members (q) and membership fee (p) have a linear relationship.
A) At what membership price, p, is the revenue maximized?
p=$??. Round your answer to 2 decimal places.
B) What is the maximum annual revenue?
R=$??. Round your answer to 2 decimal places.
Note: Round all coefficients of your revenue function to 2 decimal places.
The price at which revenue is maximized is $ 157, and maximum annual revenue is $ 6751.
Since at HD Sport & Fitness gym, analysis shows that, as the demand of the gym, the number of members is 83 when annual membership fee is $ 17 per member and the number of members is 81 when annual membership fee is $ 24 per member, and the number of members and membership fee have a linear relationship, to determine at what membership price is the maximized revenue, and what is the maximum annual revenue, the following calculations must be performed:
17 x 83 = 1411 24 x 81 = 1944 31 x 79 = 2449 38 x 77 = 2926 66 x 69 = 4554 73 x 67 = 4891 80 x 65 = 5200 94 x 61 = 5734 101 x 59 = 5959 122 x 53 = 6466 129 x 51 = 6579 150 x 45 = 6750 157 x 43 = 6751 164 x 41 = 6724
Therefore, the price at which revenue is maximized is $ 157, and maximum annual revenue is $ 6751.

Step-by-step explanation:
These two angles both containing an x are equal. They are called vertically opposite angles.
2x + 62 = 5x + 38 Subtract 2x from both sides
2x-2x + 62 = 5x -2x + 38 Combine
62 = 3x + 38 Subtract 38 from both sides
62 - 38 = 3x - 38 + 38 Combine
24 = 3x Divide both sides by 3

Find the slope of the line graphed.
My Answer:
Answer:
The slope is (2/5) or 0.40
Step-by-step explanation:
Slope is the rise of the line (y axis) over run (x axis). Take any two points. I picked (0,-2) and (5,0). The run is the change in x, which is (5 - 1) or 5. The rise for this change in x is (0 -(-2)) = 2. Rise/Run = 2/5 or 0.40.
