Since children have a population of 3000 with 150 degrees
Divide both 150 and 3000 by 150 to get 1:20
Then multiply 20 with 360 to get the total population
Total Population: 7200
And since we have the ratio of degrees to population
We multiply 20 to the others to get
Number of Men: 1800
Number of Women: 2400
The correct answer is<span> 3. x-84=3x
That's because
</span>X/12 - 7 = x/4 is also (x-84)/7 = x/4 and when you cross multiply it you get (x-84)*4 = x * 7
4x-336=7x
-3x = 336
x = 336/-3
x = -112
Answer:
5.5
Step-by-step explanation:

Answer: They are equal
Step-by-step explanation:
One hectogram is equal to 0.1 kilogram
Given :
A cylindrical tank with radius 3m is being filled with water at a rate 4m³/min.
To Find :
How fast is the height of the water increasing.
Solution :
We know, volume of cylinder is given by :
....1)
Also, we have given that, 
.
Differentiating equation 1) w.r.t t we get :
Therefore, the height of water is increasing at a rate of 0.141 m/min.
