What is value of x<br> Plz help
KatRina [158]

Answer:

10√2

Step-by-step explanation:

This is a 45-45-90 triangle which means that the two non-hyptonouse lenghts are the same which means that the bottom lenght of the triangle is also 10 units

We can then use a^2+b^2=c^2 to solve for the last side

so we have

10^2+10^2=x^2

200=x^2

sqrt200=x

and I see that they want an exact answer so you simplify sqrt200 to

10√2

The school production of​ 'Our Town' was a big success. For opening​ night, 392 tickets were sold. Students paid ​$3.00 ​each, w
elixir [45]

Answer:

<u>239 students and 153 non-students attended to the school production of "Our Town"</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of tickets of the school production sold = 392

Student ticket cost = US$ 3

Non-students ticket cost = US$ 5

Total collected = US$ 1,482

2. How many students and how many​ non-students attended?

For answering the question we will use the following equation:

x = Number of students that attended the school production

392 - x = Number of non-students that attended the school production

3x + (392 - x) * 5 = 1,482

3x + 1,960 - 5x = 1,482

-2x = 1.482 - 1,960

-2x = - 478

x = -478/-2

<u>x = 239 ⇒ 392 - 239 = 153</u>

<u>239 students and 153 non-students attended to the school production of "Our Town"</u>
