Answer:
The answer is A cos(A)cos(B)
Step-by-step explanation:
I just took it
150 114 84 60 42 30 24
from right to left the difference between numbers is increasing by an extra 6 each time
24 +6 =30 + 12 =42 +18 = 60 etc
Well, it says that 34 kids like physics and since there is 100 students, we know 34% of the kids like physics. This means 66% like biology.
Since 30 lights are 40% of them:
30*2= 60
Since 2*40= 80
We still need the 20 percent.
Half of 40= 20.
30/2= 15
So, 15+60= 75
75 is the number of lights on the tree.
I hope this helps!
