We can form two equations, let the price of a senior ticket be s and the price of a child ticket be c.
We have from day 1:
A: 3s + 9c = 75
And from day 2:
B: 8s + 5c = 67
Now we can rewrite A as:
A: 24s + 72c = 600
And can rewrite B as:
B: 24s + 15c = 201
Now A-B can be written as:
A-B: 57c = 399
So c = 7
Now substituting this back into A we get:
A: 3s + 63 = 75
A: 3s = 12
So s = 4
We have the price of a senior ticket is $4 and the price of a child ticket is $7
Answer:
a ≈ 14.39
Step-by-step explanation:
7² + a² = 16²
49 + a² = 256
49 - 49 + a² = 256 - 49
a² = 207
√a² = √207
a = 14.3874945699
a ≈ 14.39
Answer:
I think this is how you use it.
Use the side lengths to classify the triangle as acute, right, or obtuse. Classify the triangle as acute, right, or obtuse. Compare the square of the length of the longest side with the sum of the squares of the lengths of the two shorter sides. Compare c2 with a2 b2.
The correct answer would be D and I'll explain why. The table is giving you coordinates that are supposed to be on the coordinate plane. When reading coordinates and placing them on a plane x goes before y. Therefore the first point would be (3, -4). Because 3 is x, you need to go along the x-axis until you find a positive 3 - which would be to your right. Next is -4 on the y-axis, which would be the vertical line. The positives will always be above and to the right. Since it's a negative number, you go down until you find a negative 4. Now that you've found where 3 and -4 is, see where they intersect and that's where the point will be. Now, you can continue like this for the rest of the coordinates.
