Hello! To find the answer to this, we must add all of the first 5 numbers. When you do that, the sum should be 81. You must do 16 * 6 to find the number of points combined he needs to add up to the average. 16 * 6 = 96. 96 - 81 = 15. On the 6th test, you must score 15 points to have an average of 16 points. The answer is 15.

Sean tried to drink as fast as he could. He drank the slushy at a constant rate. There were originally 275 milliliters of slushy
loris [4]

a. Sean drank at a rate of 5 milliliters per second.

b. It took Sean 55 s to drink all the slushy.

<h3>a. How to find the rate at which Sean drank?</h3>

Since Sean darnak at a constant rate and originally there were 275 milliliters of slushy in the cup. After 13 seconds, 210 milliliters of slushy remained.

The rate at which Sean drank, r = Change in volume of slushy/time for change

= (275 mL - 210 mL)/13 s

= 65 mL/13 s

= 5 mL/s

So, Sean drank at a rate of 5 milliliters per second.

<h3>b. How long did it take Sean to drink all the slushy?</h3>

The time it takes Sean to drink all the slushy is given by

T = V/r where

  • V = total volume of slushy = 275 milliliters and
  • r = rate of drinking by Sean = 5 mL/s

So, T = V/r

= 275 mL/5 mL/s

= 55 s

So, it took Sean 55 s to drink all the slushy.
