If it takes the cold water faucet x minutes to fill 1 tub, then its flow rate is (1 tub)/(x min).
The hot water faucet takes 4 times as long, so its flow rate is (1 tub)/(4x min).
Together, the total flow rate is (1 tub)/(3 min), so we have
<span>D No, it is not. A straight angle has a measure greater than 90°, but it is not an obtuse angle.
The sentence should say: </span>An obtuse angle is an angle whose measure is greater than 90° but less than 180°
Remark
I take it that you mean y^2 = 36x. The first thing you should try and do is get a graph of the given equation. I've done that for you. Notice a few characteristics.
1. The graph opens left. Usually most graphs like this one open up or down.
2. The graph is open ended on the right.
3. There is only one open end.
4. The graph is continuous, but it is not a function. (that's a fact -- but not needed in this question).
When you get a graph looking like this, you have either a graph called a quadratic or a parabola. Either (but not both) could be your answer. If you have choices list them in a comment.
