Answer:

B =102

Y = 32

Step-by-step explanation:

Solving (47):

To solve for B, we have:

B + 50 + 28 = 180 --- sum of angles in a triangle

This gives

B + 78 = 180

Collect like terms

B =- 78 + 180

B =102

Solving (48):

To solve for Y, we have:

X + Y+ Z = 180 --- sum of angles in a triangle

This gives

Y = 180 - X - Z

Where

W+ X=180 -- angle on a straight line

Solve for X

X=180 -W

X=180 -100 = 80

So, we have:

Y = 180 - X - Z

Y = 180 - 80 - 68

Y = 32

There are 12 contestants in a coloring contest. Three ribbons will be awarded. How many different ways could the ribbons be awar
Elanso [62]

Answer:

1320 ways

Step-by-step explanation:

Here we have a situation where 3 ribbons will be awarded to 3 of the 12 contestants. We can use the permutation formula, because the order of awarding the ribbons matters.

The permutation formula is:

_{n}P_{k}=\dfrac{n!}{(n-k)!}

n = 12

k = 3

Now that we have our variables, let's plug them into the formula.

_{12}P_{3}=\dfrac{12!}{(12-3)!}

_{12}P_{3}=\dfrac{12!}{9!}

_{12}P_{3}=1320

So there are 1320 different ways that the contestants will be awarded.
