Answer: 2/3 of an hour.
Step-by-step explanation: The constant rate of the lifeguard filling the pool is 1/3 of the pool every 1/2 hour. If she fills it for an hour, she'll get 2/3 of the pool filled. Therefore, it'll take the lifeguard 1 hour to fill the pool 2/3 of the way.
Hope this helps! :)

Answer:
Step-by-step explanation:
If y= x + 4 then plug it into the other equation where the y is. So 5x + x +4=22. Then solve.
for x for y
5x + x + 4=22 y=x +4
6x+4=22 y=3+4
22-4=18 y=7
6x = 18
18/6=3
x=3 so, x=3 and y=7
Answer:
It must be longer than the original segment.
Step-by-step explanation:
Let analyse all the 4 answers:
- a. It divides the original segment into two equal pieces.
Yes because It finds the midpoint of the given line segment.
- b. Every point on the perpendicular bisector is the same distance from both end points of the segment.
Yes, because perpendicular bisector theorem states that if a point is on the perpendicular bisector of a segment, then it is equidistant from the segment's both endpoints.
- c. It must be longer than the original segment
Wrong, it can be shorter or equal to the original segment.
- d. It is perpendicular to (makes a 90 angle with) the original segment
True, because of it is one of the the properties of a perpendicular bisector of a segment
So we choose C.
Hope it will find you well.
