The grandparents that shop at Greggslist was 3 out of the 25 sampled. That gives us a ratio of 3/25. Convert this to decimal by dividing 3 by 25 and your answer is
3/25 = 0.12
Answer #3
Answer:
cos(60) cos(-20) - sin(60) sin(-20) = cos (40)
Step-by-step explanation:
Using the trigonometric identity rule:
Given that:
cos(60) cos(-20) - sin(60) sin(-20)
Let A = 60 and B = -20
then;
Using identity rule:
Therefore, the following as a function of a single angle is cos (40)
Answer:
Step-by-step explanation:
I think you need to first find the surface area for the 3 composite shapes which is the cube and the two triangular pyramids.
Once you have the surface area for all the three, then just add all of them together.
