Answer: The total number of visitors in first 8 weeks is 12750.
Step-by-step explanation: Given that the number of visitors to a website in the first week is 50. The number of visitors each week is double the number of visitors the previous week.
We are to find the total number of visitors to the website in the first 8 weeks.
Number of visitors in 1st week = 50.
Number of visitors in 2nd week = 50 × 2 = 100.
Number of visitors in 3rd week = 100 × 2 = 200.
Number of visitors in 4th week = 200 × 2 = 400.
Number of visitors in 5th week = 400 × 2 = 800.
Number of visitors in 6th week = 800 × 2 = 1600.
Number of visitors in 7th week = 1600 × 2 = 3200.
Number of visitors in 8th week = 3200 × 2 = 6400.
Therefore, the total number of visitors in the first 8 weeks will be
Thus, the total number of visitors in first 8 weeks is 12750.

Step-by-step explanation:
Find the diagram attached
Volume of the rectangular pyramid = BH/3
B is the base area
H is the height of the pyramid
Given
Base area = 3.2in * 1.4in
Base area = 4.48sq. in
Height = 2.8in
Volume of the rectangular pyramid = 4.48*2.8/3
Volume of the rectangular pyramid = 12.544/3
Volume of the rectangular pyramid = 4.2 cubic inches
Answer:
This is the same as writing (n-m)/n
Don't forget about the parenthesis if you go with the second option.
==================================================
Explanation:
The probability that she wins is m/n, where m,n are placeholders for positive whole numbers.
For instance, m = 2 and n = 5 leads to m/n = 2/5. This would mean that out of n = 5 chances, she wins m = 2 times.
The probability of her not winning is 1 - (m/n). We subtract the probability of winning from 1 to get the probability of losing.
We could leave the answer like this, but your teacher says that the answer must be "in the form of a combined single fraction".
Doing a bit of algebra would have these steps
and now the expression is one single fraction.
