Answer:
a.V=5/6T
b. 350 ml
Step-by-step explanation:
a.
V∝T
or V=kT
where k is a constant.
V=250 ml
T=300° K
250=300 k
k=250/300=5/6
so V=5/6 T
b.
V=5/6 T
=5/6×420
=5×70
=350 ml
Hey! I believe the answer is A. Have a nice/great day! :-)
3 liters of soda
1.5 pints of sherbet
4.5 cups of ice

Step-by-step explanation:
Let's pick two points on the line:
and
Let's calculate the slope of this line using these points:

With this value of the slope, we can write the general slope-intercept form of the equation as

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

Therefore, the slope-intercept form of the equation is

7km/ 4km per hour = 1 3/4 hours
3/4 hour = 45 minutes
Total time = 1 hour and 45 minutes.
