<span>To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100.
1520-950=570
570÷950= 0.6 × 100=60%

Answer: 63 degrees.
1. The Vertical Angles Theorem marks “x” as equivalent to its opposite angle (Angle A).
2. Angle A is apart of a 90-45-45 right triangle (since Angle B is 90 degrees).
3. Angle A and C are equivalent because of the 45-45-90 relationship.
4. Angle C is the vertical angle of the angle measuring 63 degrees.
5. So Angle X=Angle A=Angle C= 63 degrees.
The probability that a green marble is randomly drawn will be 2% if 50 blue marbles are removed. The probability of randomly picking a green marble will be greater if there are fewer marbles.
The probability of an event can be expressed as
P(A) = n(A) / n(S)
Where
- P(A) = 2% = 0,02
- n(A) = 1 (number of green marble)
We must find the value of n(S) (the total number of marbles) so that we know how many marbles that must be removed.
- P(A) = n(A) / n(S)
- 0,02 = 1 / n(S)
- n(S) = 50
Hence, the probability of randomly drawn green marble will be 2% if there are 50 marbles. So, 50 blue marbles should be removed.

Answer:
Total Cost = 14.50
Step-by-step explanation:
We have to assume that the third child pays a regular fee to get in.
2 adults = 2 * $4.50 = $9.00
2 children = 2*$2.75/2= $2.75
1 more child<u>=1*$2.75 = $2.75</u>
Total $14.50
The 2 children 1/2 price is rather tricky. You could firgure out what 1/2 price is and then just double it, but that is rather long. And it will come to what I have. So let's try it
1/2 of 2.75 = 1.375
2 * 1.375 = 2.75
It is just as easy to show it rather than doing it.
