Answer:
252 square inches
Step-by-step explanation:
Georgia needs 4 triangles, each of which has a base of 9 inches and a height of 14 inches. The area of a triangle is ...
A = (1/2)bh
so one face of Georgia's pyramid will have an area of ...
A = (1/2)(9 in)(14 in) = 63 in^2
Then all four faces will have a total area of ...
(63 in^2) · 4 = 252 in^2
_____
Comment on the pattern
The pattern shown includes the base of the pyramid. The problem text says the base is not included. We have assumed that the base is not included. (For Georgia's pyramid, a different pattern would be more to the point: see attachment.)

Answer:
320
Step-by-step explanation:
5, 20, 80,5,20,80,5, comma, 20, comma, 80, comma is not a geometric sequence.
However, if you mean 5, 20, 80 it is a geometric sequence.
It is being multiplyed by 4 each time
so 80*4=320
The next number would be 320.
Answer:
The Answer is A. 1.4 x 10^5
Step-by-step explanation:
Numbers in Scientific notation have the first number between 1 and 9 and then the decimal, followed by the rest of the numbers. Find the power of 10 by moving the decimal one place a time from right to left until the decimal is between the last number and the next to last.
B. is wrong because the number is .32 x 10^3 instead of 3.2 x 10^2
C. is wrong because it is 2 to the 10th power (2^10) instead of a power of 10
D is wrong because the number is 11.2 x 10^1 instead of 1.12 x 10^2
Hope this helps!! Have an Awesome Day!! :-)
