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.

Solve the equation: 3/8g + 2 = 5
Answer:
3/8g + 2 = 5
Subtract the number 2 from both sides of the equation.
3/8g = 3
Now divide 3/8 from both sides of the equation.
3/8 divided by 3/8 equals 0. 3 divided by 3/8 equals 8.
The final answer is:
g = 8
------------------------------------------------------------------------------------------
Check your answer:
3/8g + 2 = 5
Substitute 8 into the spot where the variable g was.
3/8 X 8 + 2 = 5
So our answer x = 8 is true.

Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 850 points. The number of two-point field goals that Lindsey made was 57 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 41 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Lindsey Smith made during the 2006 regular season.
Answer:
She made 138, 179 two point field goals and 118
3-point field goals during the regular season
Step-by-step explanation:
Answer:
118, 138, and 179 points
Step-by-step explanation:
x = 3-point goals
2-point goals = 2x - 57
free throws = 2x - 57 - 41
3x + 2x * (2x - 57) + (2x - 57 - 41) = 850
3x + 4x - 114 + 2x - 98 = 850
9x = 1062
x = 118
2x - 57 = 2 * 118 - 57 = 179
2x - 57 - 41 = 138

help me find x in this triangle
Answer:
x=176 degrees
Step-by-step explanation:
The first step to solving this is filling out any information we have. We know a solid line is 180 degrees, so the angle next to 92 must be 88.
We also know that the length of the line dividing 92 and 88 is equal to the other line with a small line in the middle. Because of this, the angle above the first 88 we found is also 88 degrees.
Now that we know two of the angles in the triangle add up to 176, we can figure out that the other angle is equal to 4. We know this because the sum of the interior angles of a triangle must equal 180.
This may seem off to you, but keep in mind that this diagram is likely not to scale.
Using the same rule we used for the first part we did, we can deduce that x equals 176.

Answer:
A
Step-by-step explanation:
you just follow the trail
Answer:
A - 2
Step-by-step explanation:
It can't be B or D, because the other triangle is bigger than the first one.
It is not 4 because if you count the squares, you will notice that b=2 and a=4. So the scale factor is 2.
