Answer:

x = 6

y = 5

Step-by-step explanation:

These shapes are similar. Since you multiply 3 to 3 for 9, multiply or divide by 3 for the rest of the numbers as well. For the x, multiply 2x3 for 6. And for the y divide 15/3 for 5.

Hope it's correct!

Answer:

x = 6, ∠ B = 126°

Step-by-step explanation:

∠ A and ∠ B are alternate angles and congruent, so

8x + 78 = 2x + 114 ( subtract 2x from both sides )

6x + 78 = 114 ( subtract 78 from both sides )

6x = 36 ( divide both sides by 6 )

x = 6

Then

∠ B = 2x + 114 = 2(6) + 114 = 12 + 114 = 126°

PLEASE HELP DUE IN 30 MIN I WILL GIVE BRAINLIEST PLEASE HELP AND DONT SPAM PLEASE HELP IM ALREADY FAILING MATH :-(

Answers

System of equations will be important here. We have two pieces of information: how many tickets were sold, and the total price.

A= adults, S = students

A + S = 155 (# of tickets)
7A + 3S = 645 (total profit)

S = 155 - A , based on the first equation

Now substitute S into the second equation.

7A + 3(155 - A) = 645

7A + 465 - 3A = 645

4A = 180

180/4 = 45 adult tickets sold.

The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds
600 people. By selling tickets, the members would like to raise $
3,300 every night to cover all expenses. Let d represent the number of adult tickets sold at $
7.50. Let s represent the number of student tickets sold at $
4.50 each. If all
600 seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $
3,300? At one performance there were
two times as many student tickets sold as adult tickets. If there were
360 tickets sold at that performance, how much below the goal of $
3,300 did ticket sales fall?

Answers

a) At $3,300 for 600 seats, the average price per seat is 3300/600 = $5.50. The mix of tickets that results in that average can be found using an X diagram as shown below. The numbers on the right are the differences along the diagonals. When they are multiplied by 2, they add to 600. This shows that the required sales for revenue of $3,300 are
200 adult tickets
400 student tickets

b) When 3 student tickets are sold for each adult ticket, the average seat price is
(3*$4.50 +7.50)/4 = $5.25
Then the shortfall in revenue is ...
$3,300 -480*$5.25 = $780

The length of the hypotenuse (x) is an irrational number between 6 and 8. Both legs have measured that are whole numbers. What is one possible set of measures for the sides of the right triangle

HELP ME PLEASE !

Answers

Step-by-step explanation:

Since 6 < x < 8, we have 36 < x² < 48.

Let a and b be the sides of the right triangle.

a²/b² could be 1², 2², 3², 4², 5² and so on.

A possible set of measures is 6 and 2.

This will give x² = 6² + 2² = 40, x = √40 which is irrational.
