Tickets to a local circus cost $5 for students and $8 for adults. A group of 9 people spent a total of $60. How many adults were

S_A_V [24]

Answer:

Step-by-step explanation:

You need to set up and solve a system of linear equations here.

Let s and a represent the number of students and adults respectively.

Then s + a = 9, and s = 9 - a.

Total ticket cost for the adults was ($8/adult)(a)

and for the students ($5/student)(s).

Total cost of the tickets was then ($8/adult)(a) + ($5/student)(s) = $60.

Then our system of linear equations is:

8a + 5s = 60

a + s = 9, or s = 9 - a. Substituting 9 - a for s, we get:

8a + 5(9 - a) = 60.

Then 8a + 45 - 5a = 60, or 3a = 15.

Solving for a, we get a = 5.

Solving for s using s = 9 - a, we get s = 9 - 5, or s = 4.

There were 5 adults in the group (and 4 students).

What is the domain of the function using the graph?

Fofino [41]

The answer is B) x is equal to all real numbers.

The domain of a function is the numbers for x that you can put in. Although the y-values are restricted here, you can put any number you want in for x. Therefore, x is equal to all real numbers.

What is the length of the missing leg? If necessary, round to the nearest tenth.

BabaBlast [244]

Answer:

The length of the hypotenuse is 40 mm.

Step-by-step explanation:

We can solve for 'a' using Pythagoras theorem. Let's solve it.

10² = 5² + a²
=> 100 = 25 + a²
=> a² = 75
=> a = 8.660
=> a = 8.7

Hence, the length of the hypotenuse is 8.7 m.

Hoped this helped.
