In x th month, members = 
. Option D.
Step-by-step explanation:
Given,
Initially number of members = 3
Every month each member brought 1 new member.
To find the number of members after x months.
<u>Solution:</u>
In 1st month, members = 3
In 2nd month, members = 3×3 = 9 = 3²
In 3rd month, members = 9×9 = 81 = 
In 4th month, members = 81×81 = 81 = 6561 = 
Hence,
In x th month, members =
The figure below shows a triangular wooden frame ABC. The side AD of the frame has rotted and needs to be replaced:
Triangle ABC has length of BC equal to 10 inches. A line segment DC joins the point D on AB with point C. Measure of angle ABC is 90 degrees, ACD is 15 degrees and measure of angle DCB is 30 degrees.
What is the length of the wood that is needed to replace AD?
Answer:
First photo, I think they are all the same
Second, see below
Step-by-step explanation:
<u>Numbering is by the numbers next to the problem, not the order of the photos</u>
(2) Biggest area
[] Find alllll the areas and compare! Area is base x height divded by 2
[] A
2 x 4 / 2
8 / 2
4
[] B
2 x 4 / 2
8 / 2
4
[] C
2 x 4 / 2
8 / 2
4
[] D
2 x 4 / 2
8 / 2
4
Now, I think this is a trick question and they are all the same areas. I am not 100% sure, but if you do the math that is what you get :)
(1) Drawing heights
[] The height is from the middle of the base to the point across. For the one on the left you would find the of the base and draw a straight line into the corner across from it at the bottom right.
[] The one on the right would be the same, but it would go into the narrower corner on the top
(Hopefully this helps and is correct! Have a nice day :D)
