A school carnival sold 27 early-admission tickets and 3 regular tickets. What percentage of the tickets sold were early-admission tickets?

Answers

Answer:

Step-by-step explanation:

There is a total of 27 tickets, and 3 of them are regular tickets

To find the percentage, we divide early-admission tickets by the regular tickets , which is 27/3.

We can then simplify 27/3, or 9 which is 90%.

Answer:

90%

Answers

it is c.

explanation:

20+130+h =180

when you solve you get h=50

130+g = 180

g= 50

50+60+f = 180

f=70

as the summation of all angles in a triangle must be 180

∠H = 180 - (130 +20)

= 180-150

=30

as the straight line has an angle of 180

∠G= 180 - 130

= 50

since that

∠f = 180- (50+60)

=180- 110

=70

answer is C

Step-by-step explanation:

18 / 4 = 4.5

Okay, you would know that 16 / 4 = 4.
So that solves 1 part. Next, you have to divide 2 / 4. Which would equal 0.5.

Then you add 4 to 0.5, which is 4.5!

I really do hope this is the answer but I am really sorry if this is wrong

Step-by-step explanation:

the main equation would be

210+3x>288

first I divided 210 by 3 to see how many mugs he has sold first. Then I got an answer of 70 mugs sold. after that i subtracted 210 from 288 and got 78. After this I divided 78 by 3 to get a count of how many mugs Ronny needs to sell. so The total amount of mugs Ronny needs to sell to reach his goal of 288$ is 96. But he has already sold 70 so he needs to sell 26 more mugs.

The area of a 2D form is the amount of space within its perimeter. The total surface area of the square base pyramid is 297mm².

What is an area?

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The total surface area of the square pyramid is the sum of the area of the triangles and the area of the base. Therefore, the total surface area is equal to,

Total surface area = Area of square base + 4(Area of a triangular face)

= (9mm)² + 4(0.5×9×12)mm²

= 81mm² + 216mm²

= 297mm²

Hence, the total surface area of the square base pyramid is 297mm².
