Answer: A number is divisible by 3 if the sum of its digits is divisible by 3. A number is divisible by 9 if the sum of its digits is divisible by 9. And a number is divisible by 6 if it is divisible by 2 (even number) and by 3.
Answer:
Ok
Step-by-step explanation:
it's 5 dollars for 4 pounds of apples
Answer: angle 6 is 30 degrees
Step-by-step explanation:
they both must equal 180 degrees so if you subtract 150 from 180 you get 30
You can use synthetic division since the divisor is a linear binomial
x + 3 = 0 so x = -3
-3| 2 3 8
___-6__9_
2 -3 | 17 ←ignore remainder
y = 2x - 3
The picture shows how this would look as a triangle.
In this case, we would use tan. x is the opposite side, and 80 is adjacent.
tan(85.7) = x/80
13.299.. = x/80
x = 1,064 feet
