Answer:
64.3 lumens
Step-by-step explanation:
Data provided in the question:
Length of the testing chamber = 35 cm
Light at one end = 10 lumens
Light at other end = 200 lumens
now,
since the variation is linear,
therefore, the gradient of the variation
= 
= 5.43
also,
the darkest end is the end with 10 lumens
therefore,
The lumens at 10 cm from the darkest end
= 10 + 5.43(10)
= 10 + 54.3
= 64.3 lumens
This is how proportion is written 7:21=3:9. The colons are sign of division so it can be shown in the terms of fraction as 7/21=3/9 or 1/3=1/3
The rate at which Sean drank the slushy is 5 milliliters per second.
The time it would take to drink all the slushy is 55 seconds.
<h3>How fast did Sean drink?</h3>
In order to determine the speed at which the slushy was drank, divide the slushy drank in 13 seconds by 13 seconds.
Speed = slushy drank in 13 seconds / time
(275 - 210) / 13
65 / 13 = 5 milliliters per second
Time it would take to drink all the slushy =total milliliters of the slushy / speed
275 / 5 = 55 seconds.
