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
Answer:
---- in dollars
---- in cents
5 dollars 94 cents
Step-by-step explanation:
Given
Pears
per pound
Grapes
per pound
Required
Determine the amount paid for the fruit in dollar and cents
First, we need to calculate the amount paid for each fruit.
This is calculated by multiplying the amount per pound by the number of pounds bought.
For Pears:
Convert fraction to decimal
For Grapes
Convert fraction to decimal
Next, we add both amounts together to get the total amount spent in dollars.
Multiply by 100 to convert this amount to cents
And it can be represented as dollars and cents as:
5 dollars 94 cents
