There were 450 tickets purchased for a major league baseball game. the general admission tickets cost $6.50 and the upper box ti
lidiya [134]

Answer:

Step-by-step explanation:

So you first pretend they were all the general admission tickets which is

450x6.50$=2925$ So the number is 4237.50$-2925$=1312.50$ away from the actual price. The price difference between the two is 10.00$-6.50$= 3.50$

Then you put the total price difference 1312.50$ and divide by 3.50$ then you get the amount of upper box tickets. 1312.50$/3.50$=375( Amount of Upper box. So now you know how many upper box were bought. You take it away from 450 tickets sold. 450-375=75

375x10=3750$

75x6.5=487.5$

3750$+487.5$=4237.5$

Hope that helped you!

When NB = 12 ft, find the area of the region that is NOT shaded. Round to the nearest tenth.
Alborosie
If this item has the same picture on the same question posted before, the following will be the data.

Given: NB = 12 ft, Angle-120°<span>
Asked: area of the region that is not shaded.
Substitute the given values in the equation in finding the area of a circle.
</span>A = πr² 
<span>A = ⅔π(12 ft)² </span>
<span>A = 96π ft² 
(Since </span>120° is 1/3 of the circle. it is then understood that the unshaded parts must be 2/3 of the circle.)
Since you already have the area, find the area of the triangle to add it to the area of the circle to find the area of the unshaded part. By using a handy trigonometry, you can tell that their will be 2 triangles of 12 ft (if you are going to divide 120° angle). From this, you'll see that there will be one of the smaller triangles having a <span> the height of 6 ft and the base is 6√3 ft. Substitute the values.</span>
A = ½bh 
<span>A = ½(6 ft)(6√3 ft) * 2 </span>
<span>A = 36√3 ft² 
</span>
Add them up and you will have the exact answer  96π + 36√3 ft², when rounded to the nearest tenth, you will have <span> 364 ft². </span>

A convex hexagon has interior angles with measures x^0, (5x - 103); (2x + 60), (7x - 31), (6x -6), and (9x - 100), what is the v
cestrela7 [59]

Answer:

x = 30.66°

Step-by-step explanation:

The sum of the interior angles of a hexagon is 720°

Each angles are x^0, (5x - 103); (2x + 60), (7x - 31), (6x -6), and (9x - 100),

we add all these angles together

x^0 + (5x - 103) + (2x + 60) + (7x - 31) + (6x -6) + (9x - 100) = 720

x^0  = 1

1 + (5x - 103) + (2x + 60) + (7x - 31) + (6x -6) + (9x - 100)

1 + 5x - 103 +2x + 60 + 7x -31 + 6x - 6 + 9x - 100 = 720

1 - 103 + 60 - 31 - 6 - 100 + 5x + 2x + 7x + 6x + 9x = 720

1 - 180 + 29x = 720

-179 + 29x = 720

29x = 720 + 179 = 889

x = 889/29 = 30.655 ≅ 30.66°

What is the greatest common factor of 4xy^2 and 20x^2y^4
AnnyKZ [126]
4xy^2 because 4 and 20's GCF is 4
x and x^2 have X in common
and y^2 and y^4 have y^2 in common
Multiply those together and you get 4xy^2
