Answer:
18
Step-by-step explanation:
Lets factor each of them:
3:1,3
18:2*3^2
9:3^2
every factor is in 18:2,3,3...
Therefore the answer is 18.
Using the law of Cosine:
Cos(angle) = Adjacent Leg / Hypotenuse
Cos(65) = x / 81.9
x = 81.9 x cos(65)
x = 34.61
The answer is A.
21÷(2+1)5-2²
21÷10+5-4
21÷15-4
21÷11
21/11
1whole10divided by 11
0.21 is less than half because a half is 0.5.
So 0.21 is less than 0.5 because the tenths place is less than 5 which makes 0.21 smaller than a half
