we know that

the cost of one ticket is \$8

so

by proportion

<u>Find the cost of  23 tickets</u>

\frac{8}{1} \frac{\$}{ticket} =\frac{x}{23} \frac{\$}{tickets}\\ \\x=23*8\\ \\x=\$184

therefore

<u>the answer is</u>

\$184

A bowl contains 6 green grapes, 10 red grapes, and 8 black grapes. Which of the following is the correct
irina1246 [14]

Using the it's concept, the correct calculation for the probability of choosing a red grape and then without putting the red grape back into the bowl, choosing a green grape is:

p = \frac{5}{2} \times \frac{1}{23} = \frac{5}{46}

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, we have that there is a total of 6 + 10 + 8 = 24 grapes. For the first grape, 10 are red, hence the probability that the first grape is red is:

pR = \frac{10}{24} = \frac{5}[12}

For the second grape, considering that the first was red and was removed, there will be 23 grapes, out of which 6 will be green, hence the probability that the second grape is green is:

pG = \frac{6}{23}

Hence the correct expression is found as follows:

p = pR \times pG = \frac{5}{12} \times \frac{6}{23} = \frac{5}{2} \times \frac{1}{23} = \frac{5}{46}

Find the value of x that makes ABCD a parallelogram.
harkovskaia [24]

Answer:

x = 10

Step-by-step explanation:

A parallelogram's angles should all add up to 360 degrees. 130+130 is equal to 260 degrees. 360-260 is equal to 100. Because we need to find the individual angles of Angle A and Angle C, we will divide 100 by two. That leaves us with 50 degrees for Angle A and Angle C EACH. We know Angle C is equal to 5x. So, we would divide 50 by 5, which leaves us with 10 degrees. Therefore, x = 10.
