Answer:
So wavelength in decimal can be written as 0.00000155 m
Step-by-step explanation:
We have given wavelength of light used in optic fibers is 
We have to convert this wavelength in decimal form
We know that
can be written as 
So 
So wavelength in decimal can be written as 0.00000155 m

Answer:
6.5
Step-by-step explanation:
Each term in this sequence is the previous term divided by -2:
104/-2=-52
-52/-2=26
26/-2=-13
So in order to find the next term, we just need to divide the last term by -2:
-13/-2 = 6.5
The next term in the sequence is 6.5
Hope this helped!
Answer:
Length of string used by Claire = 7 / 3 feet
Step-by-step explanation:
Given:
Length of string Claire in starts =
feet
Length of string Claire in end =
feet
Find:
Length of string used by Claire
Computation:
Length of string Claire in starts =
feet = 25 / 6 feet
Length of string Claire in end =
feet = 11 / 6 feet
Length of string used by Claire = Length of string Claire in starts - Length of string Claire in end
Length of string used by Claire = [25 / 6] - [11 / 6]
BY taking LCM
Length of string used by Claire = [25 - 11] / 6
Length of string used by Claire = 14 / 6
Length of string used by Claire = 7 / 3 feet
Answer:
15p
Step-by-step explanation:
<u>Let's interpret the question bit by bit</u>
<em>Salvador wrote 15 letters to friends each month</em>
=> 15 letters = 1 month
<em />
<em>For p months in a row</em>
let the total number of letters for p months be x
=> x letters = p months
<em>Bringing the two statements together gives;</em>
15 letters = 1 month
x letters = p months
<em>Now, let's solve for </em><em>x </em><em>by cross-multiplying the above</em>
x letters * 1 month = 15 letters * p months
x = 
x = 15p letters
Therefore, Salvador wrote a total of 15p letters for the p months.
