First, find the area of the plot.
Area = length x width
Area = 12 x 5
Area = 60 square feet.
The ratio of the scale to the plot is 1 inch : 2 feet
Square each of those:
1 square inch : 4 square feet
The plot is 60 square feet. 60 sq ft / 4 sq ft = 15
The area of the plot in the scale drawing is 15 square inches.
Based on my little knowledge of statistics
4.
It's 8!/4!= 1680
(the exclamation point is basically the number of probabilities in the combination)
5.
(speculation) It's 10!-6!= 3,628,080
plus
8!-6!=39,600
equals
(3,628,080 + 39,600) / 6! = 5094
(the 6! is the amount of drink combinations you are limited to)
FYI- you can use the exclamation mark on your phone calculator, either swipe to side or press the ''extras'' button
I can tell you what it is but without a picture i can not help you.
A cross section of anything is when the shape is getting cut straight into an object. It is like viewing the inside of something made by cutting through the object.
So look at the patterns.
How much bigger is 15 to 3?
Answer = 5x bigger.
What is 5x smaller than 40? (in other words, 5 x ? = 40)
Answer = 8!
So, the missing 'x' = 8
