Answer:
3, 6, 9
Step-by-step explanation:
When changing a fraction to a decimal, you divide the numerator by the denominator. For EX.
1/3= 1 divided by 3
1 divided by 3 is 0.3333333333333
1/6
1 divided by 6 is 1.6666666666666
1/9
1 divided by 9 is 0.1111111111111111111111
A. 24 miles
Explanation:
the area inside a circle is given by:
where r is the radius of the circle.
In this problem, we know the circular area:
So we can re-arrange the equation above to find r, the radius:
so, the radius of the circular area is 24 miles.
Answer:
250 tagged 5500 total = 15 tagged x total x=330 fish were sampled.

Answer:
CA ≈ 3.1 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° = 
= 
= 
( multiply both sides by CA )
CA × tan40° = 2.6 ( divide both sides by tan40° )
CA = 
≈ 3.1 ft ( to the nearest tenth )
Answer:
1
Step-by-step explanation:
4+x+4+x+1+x=6(2x)
3x+9=12x
3x-12x=-9
-9x=-9
9x=9
x=9÷9
=1
