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:
okay but this is not a question your just telling me this
Step-by-step explanation:
We will not know the answer because you didn't tell us the radius or anything
Answer: 94.5
Step-by-step explanation:
9/2 × 21/4
Get common denominator
9 × 2 =18
2 × 2 = 4
18/4 × 21/4
21 × 18 = 378
378/4 = 94.5
Answer:
6.64 seconds
Step-by-step explanation:
Given that:
Distance between roof of the terminal and ground = 709 feet
A bucket was dropped from the roof.
To find:
The time taken by the bucket to hit the ground?
Solution:
Distance traveled,
= 709 feet
Initial velocity of the bucket,
= 0 feet/sec (because initially it was at rest)
Acceleration of the bucket will be equal to acceleration due to gravity i.e.
or 32.1741 
Let the time taken is
seconds.
Formula for distance is given as:

Putting all the values:
