Answer:
The pump fill the pool in 3/5 hours
Step-by-step explanation:
From noon to 1/4 hours later, the pool goes from 1/3 to 3/4 full. That's means that the pool fill X quantity in 1/4 hours, where X is calculate as:
So, the constant rate R can be calculated as:
That means that every hour the pool can be fill 5/3 full, so if we want to know how many hours is needed to fill the poll one time, we can write the following equation:
Where t is the time required to fill the pool. Solving for t we get:
t = 3/5 hours
so, the pump fill the pool in 3/5 hours or 36 minutes with a constant rate of 5/3.
Because it has more mass so with less mass it accelerates faster. That is newtons 2nd law of motion.
Answer:
two functions f & g, then for all values of x for which both f(x) and g(x) are defined, the functions f + g, f-g, fg, and f/g are defined as follows.
Sum: Add the LIKE terms
Difference: Subtract the LIKE terms
Product: Distribute or FOIL
Quotient: Set up a fraction, then STOP - (Always state that the denominator ≠ 0)

Answer:
x = 2
Step-by-step explanation:
Since the central angles are congruent, and all radii are congruent, the triangles are congruent. By CPCTC x = 2.
