A nice physics problem.
But 16t 2 is inappropriately written; you meant x = 16t^2, where "^" represents exponentiation.
The appropriate formula applying to this situation includes a "t" term which is not present in yours. Start with this:
s = s_0 + v_0t + (1/2)a^t^2, where x_0 is the initial height above the ground and v_0 is the initial velocity. "a" represents acceleration an here is -32.2 ft/(sec^2).
Here's how we apply this formula:
0 ft = 64 ft + 0*t + (1/2)(-32.2 ft/(sec^2), or
0 ft = 64 ft - 16.1 ft/(sec^2)
You must solve this equation for time, t. It will be a positive quantity.
Answer:
m∠A = 90°
Step-by-step explanation:
In isosceles triangle base angles are congruent. That means we can equate measurments of angle B and angle C and solve for x!
m∠B = m∠C
11x - 10 = 7x + 10
4x - 10 = 10
4x = 20
x = 5
Now let's insert x back in the expressions for angles.
m∠B = (11x − 10)° = (11(5) − 10)° = 45°
m∠C = (7x + 10)° = (7(5) + 10)° = 45°
<u>Sum of all angles in the triangle is 180°.</u> Let's make an equation.
m∠A + m∠B + m∠C = 180°
m∠A + 45°+ 45° = 180°
m∠A = 90°

Answer:
75 minutes
Step-by-step explanation:
The rate at which the tank is filled up, F, and emptied, E, are respectively:
Since V is the full volume of the tank, the time required to fill the tank if both pipes are open is given by:
It will take 75 minutes to fill the tank if both pipes are open.
