Answer:
Price of senior citizen ticket = $7
Price of student ticket = $5
Step-by-step explanation:
<u>Let</u>:
- senior citizen ticket price = a
- student ticket price = b
<u>Equations formed</u> :
- 9a + 10b = 113
- 2a + 10b = 64
<u>Subtract</u> : Equation 1 - Equation 2
- 9a + 10b - 2a - 10b = 113 - 64
- 7a = 49
- a = 7
<u>Finding b</u>
- 2(7) + 10b = 64
- 10b = 50
- b = 5
<u>Solution</u>
- Price of senior citizen ticket = $7
- Price of student ticket = $5
Answer:
Your spelled formula wrong
Given the volume of a cylinder V = pi(r2)h we simply plug in the numbers
The radius is half the diameter so r = 4cm
the height h is given as 12 cm
V = 3(42)(12) = 3(16)(12) = 576 cm3
Note: Generally we would use 3.14 as the rounded value of p
First - Since you have a in the numerator and denominator, you can cancel them and get:
8r/12
Second - Since both 8 and 12 have common factors, you can find the GCF and divide both by that number.
GCF = 4
8/4=2
12/4=3
Answer:
2r/3
Answer:
Step-by-step explanation:
Merely change the sign of y.
For example, if the point (2, 3) is reflected across the x-axis, it becomes (2, -3).
