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:
The Y-intercept changes .
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
Perimeter = distance round the shape
2y + 11 + y + 3 +3y - 2 + 10 = 58
Collect like terms
2y + y + 3y = 58 - 11 - 3 + 2 - 10
6y = 36
y = 36/6
y = 6
Length PQ = 3y - 2 = 3(6) -.2 = 18 - 2 = 16
Answer:
y = 3x - 10
Step-by-step explanation:
It's not an option, but you already said in the instructions that the y-intercept is -10.
y = mx + b
M is the slope and b is the y-intercept.
