Answer:
1 and 2
Step-by-step explanation:
slope is 1
y intercept is 2
basically base it off the equation y = mx + b

the b is the y intercept, so in this case its 2
Since each min is 60 seconds you multiply 60 by the number of minutes which is 7 and you get 420:
60x7=420 Then you add 30 seconds equaling 450 seconds total
Then you divide 450 by 4 since she ran 4 laps.
So, Stephanie ran 112.5 seconds per lap
Answer:
V=113.0 ft^3
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
V = 4/3 * (3.14 ) * 3^3
V =113.04
To the nearest tenth
V = 113.0
