A = first piece, b = second piece, c = third piece
a + b + c = 47
b = 3a
c = 5a + 2
a + (3a) + (5a + 2) = 47.....combine like terms
9a + 2 = 47
9a = 47 - 2
9a = 45
a = 45/9
a = 5 ft
b = 3a.....b = 3(5)....b = 15 ft
c = 5a + 2....c = 5(5) + 2.....c = 25 + 2....c = 27 ft
longest piece (c) = 27 ft
The probability of drawing exactly one red ball is given by:

the probability of drawing two red balls is given by:

The probability of drawing at least one red ball is:
P(1 red ball) + P(2 red balls) = 16/28 + 6/28 = 11/14.
The answer is

Answer:
I suggest a bar graph.
Step-by-step explanation:
The bar graph shows how many fish per tank or in the tank.
Answer:
A. 47 degrees
Step-by-step explanation:
If both sides are equivalent in length, that means that the two remaining angles are also the same. Triangles have an interior angle sum of 180 degrees, so subtract the 86 of the angle known, and divide the remaining degrees by two to find each angle.
