Answer:
9th Triangle
Step-by-step explanation:
Given the area of four triangles:
If the Scale factor is 1.5.
This is a geometric sequence and the common ratio is 1.5 X 1.5.
Therefore, the area of any n triangle can be determined using the function:

We want to determine which triangle has an area greater than
.
When A(n)=15000

Therefore, the 9th triangle has an area greater than
.
Answer:
8Parallel lines always have the same slope.
[I attached a picture that might help show you]
The lines do
NOT Intersect.
Math:
Well, you know that 12 inches goes into 1 foot.
So, let's start with just making everything into inches.
4 feet * 12 = 48+2 = 50 inches.
3*12 = 36 inches + 7 = 43 inches.
50 - 43 = 7.
Your answer:
7 inches.
You did not put a picture or a question
67.33. You would first find the total height of people. So 50 would be multiplied by 68, giving you the answer of 3,400. After, you would subtract 82 and 86, giving you 3,232. To get the final answer you would divide the value by 48, since two of them are removed, giving you 67.33.
