Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for

opening night totaled $2071.50. The equation 10.50a + 3.75b = 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold?

Answer: There are 168 adult tickets that were sold.

Step-by-step explanation:

Let the number of adult tickets were sold be 'a'.

Let the number of student tickets were sold be 'b'.

Since we have given that

The ticket sales for opening night totaled as

10.50a+3.75b=2071.50

And the number of students attended  = 82

so, b = 82

So, we will put the value of b in the above equation:

10.50a+3.75\times 82=2071.50\\\\10.50a+307.5=2071.50\\\\0.50a=2071.50-307.5\\\\10.50a=1764\\\\a=\dfrac{1764}{10.50}\\\\a=168

Hence, there are 168 adult tickets that were sold.

Plz help me with this I don't have my protractor with me plz help and do this
My name is Ann [436]
An acute angle is an angle less than 90 degrees. (smaller angle)
A right angle is exactly 90 degrees. (right angle)
An obtuse angle is over 90 degrees. (larger angle)
A reflex angle is any angle of 180 degrees. (largest angle)

You wouldn't *really* need a protractor to complete your homework; you could guesstimate.

I hope this helps!

Answer:

  3929 square feet

Step-by-step explanation:

The radius of the fence circle is half its diameter, so is 51.4 feet. The area of a circle is given by the formula ...

  A = πr^2

The difference in areas of the two regions is found by subtracting the smaller area from the larger one. So, the difference in area between the fenced area of radius 51.4 feet and the playground area of radius 37.3 feet is ...

  ∆A = π(51.4^2 -37.3^2) = 1250.67π ≈ 3929 . . . square feet
