24$ because if its each and the number goes by 12 the 2 adults get to have 14 and the children 12 add that multiply it by the number of tickets so it's 24$

Because there is 3 letters between that. Also if its a measurment one than u forgot the picture!!!!!
hope this helps :)
Answer:
7:10
Step-by-step explanation:
14/20= 7/10
Answer:
2
Step-by-step explanation:
4.0 has 2 significant digits.
The zeros after a non zero number are significant.
Any non zero number is significant.
0.004 has 1 significant digit.
4000 has 4 significant digits.
In your case 4.0 × 10^3 there is an exception because it is in scientific notation. So there are 2 significant digits.
hope this makes sense.

Your statement that angle C and angle D adding to 180 degrees isn't always true. What is always true is that angle A and angle C add to 180 degrees.
Rule: The opposite angles of an inscribed quadrilateral are supplementary (add to 180 degrees)
So,
(angle A) + (angle C) = 180
(x+2) + (x-2) = 180
x+2+x-2 = 180
2x = 180
2x/2 = 180/2
x = 90
Once you know x, you can find the angles
measure of angle A = x+2
measure of angle A = 90+2
measure of angle A = 92 degrees
measure of angle C = x-2
measure of angle C = 90-2
measure of angle C = 88 degrees
Note how A+C = 92+88 = 180
measure of angle D = x-10
measure of angle D = 90-10
measure of angle D = 80 degrees
measure of angle B = 360-A-C-D ... see note below
measure of angle B = 360-92-88-80
measure of angle B = 100 degrees
Note: for any quadrilateral, the four angles add to 360 degrees. So A+B+C+D = 360. We can solve for B to get B = 360-A-C-D
