Answer:
36
Step-by-step explanation:
6*6=36
The area of one of the triangular lateral faces is

You're told that the slant height, which is the same as the height of the triangular face, is 9.8, so you have

where

is the length of the base of the triangle, which is also the same as the side length of the base of the pyramid. So
Option B should be the correct answer
Answer:
15.87%
Step-by-step explanation:
First thing here is that we calculate the z-score which corresponds to 76
mathematically;
z-score = (x-mean)/SD
mean = 71 and SD = 5
plugging these values, we have;
z = (76-71)/5 = 5/5 = 1
Now, we want to firstly get the probability that we have a student shorter than 76 inches
The probability we want to calculate is P(z<1)
we can get this using the z-score table directly
That would be 0.15866
In percentage that is 15.866% which is 15.87% to the nearest tenth
Answer:
(2c+14) ft
Step-by-step explanation:
The answer is (2c+14) ft because as 2 sides measure 3 feet, we have 6 feet for two sides. The other two sides measure (c+4) feet, and there is (2c+8) feet for two sides. If you add the results together, you get (2c+14) feet. Hope it helps!
