A 12-gallon tub has a faucet that lets water in at a rate of 3 gallons per minute, and a drain that lets water out at a rate of 1.5 gallons per minute. If you start with 3 gallons of water in the tub, how long will it take to ﬁll the tub completely?

Answers

Vol of water required to fill up the tub = 12-3 = 9
Rate of water per min =    3 -1.5 = 1.5/min
Using the formula           vol   =   rt
                                            t = v/r
                                            t =    9/1.5    =   6
time taken =    6 mins

Define the term PROPORTIONAL RELATIONSHIP.

Answers

Answer:

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality". Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

Proportional relationships are relationships between two variables where their ratios are equivalent.

It mentions that angle 1 is congruent to angle 2. They have the same angle measure. This allows us to replace angle 1 with angle 2 (because they're effectively the same thing).

We can say
(angle 1) + (angle 3) = 90
(angle 2) + (angle 3) = 90
notice the replacement in bold

The second equation is an algebraic way of saying "angle 2 and angle 3 are complementary"

Answer: Choice C
