Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she should put into each bag?
Answer:
Softballs = (48/b)
Step-by-step explanation:
Given that,
Total number of softballs = 48
She wants to divide them evenly among b softball bags.
We need to find an expression that represents how many softballs she should put into each bag.
As it is dividing among b softball, it means we divide 48 and b. So,
[tex]s=\dfrac{48}{b}[/tex]
Hence, the required expression is (48/b).

A triangle has one side that measures 1 foot and another side that measures 20 inches. What are possible lengths of the third side? (Select all that apply.)
6 inches
13 inches
28 inches
36 inches
Answer:
The correct options for the possible lengths of the third side are;
13 inches
28 inches
Step-by-step explanation:
The given lengths of two sides of the triangle are;
The length of one side of the triangle = 1 foot = 12 inches
The length of the other side of the triangle = 20 inches
The question can be solved by the triangle inequality theorem as follows;
A + B > C
B + C > A
A + C > B
Let the given sides be A = 12 inches and B = 20 inches
We have;
12 + 20 = 32 > C
Therefore, by the triangle inequality theorem, the third side, 'C', is less than 32 inches
Similarly, when C = 6 inches, we have;
A + C = 12 + 6 = 18 < B = 20
Therefore, the third side cannot be 6 inches
when C = 13 inches, we have;
A + C = 12 + 13 = 25 > B = 20
Therefore, the third side can be 13 inches
when C = 28 inches, we have;
A + C = 12 + 28 = 30 > B = 20
Therefore, the third side can be 28 inches
Based on the triangle inequality theorem, the possible lengths of the third side of the triangle are: 13 inches and 28 inches.
The Triangle Inequality Theorem
The triangle inequality theorem states that, sum of the length of any two sides of a given triangle = length of the third side.
Given the measures,
1 ft = 12 iches20 inchesThe possible third side must make the three set of numbers conform to the triangle inequality theorem.
Thus, for 13 inches, we have:
13 + 12 > 20; 12 + 20 > 13; 20 + 13 > 12
Also, for 28 inches, we have:
28 + 12 > 20; 12 + 20 > 28; 20 + 28 > 12
Therefore, based on the triangle inequality theorem, the possible lengths of the third side of the triangle are: 13 inches and 28 inches.

Find the given trigonometric ratio in the problem below.
Answer:
cosC = 30/50
Step-by-step explanation:
Before you find cosC, you should know that:
tangent = opposite side/adjacent side
sine = opposite side/hypotenuse
cosine = adjacent side/hypotenuse
You should also know that trigonometric ratios work for only right triangles.
If cosine = adjacent side/hypotenuse, then:
cosC = 30/50
cosC = 0.6
If rounding to the nearest four decimals, it should be 0.6000.
