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.)
What you know:
Mr. Adams spent $36.25 on 12.5 pounds.
All you do to find the cost per each pound is:
36.25/12.5
Your answer:
$2.9 dollars per pound.
The answer is 14, because the points in between are 13 and 15. ( ͡
Answer:
sq root of 26
Step-by-step explanation:
One rule of an irrational number is that it cannot be written as an whole fraction, since the other two are fractions, the last must be irrational.
Answer:
a = 12 and b = 18
Step-by-step explanation:
Given that,
8,a,b,27 are in geometric sequence.
For a GP, the nth term is given by :
Put n = 4
Put n = 2,
Put n = 3
So, the values of a and b is 12 and 18 respectively.
