Answer:
The mean is 254.5
Step-by-step explanation:
Add up all the numbers then divide by how many numbers there are.
The system of equations would be:
64x+132y = 1040
x = 2y
We multiply the number of adult tickets, 64, by the cost of the adult tickets, x. We multiply the number of student tickets, 132, by the cost of the student tickets, y. Together these add up to $1040.
We know that the cost of an adult ticket is twice as much as a student ticket, so x = 2y.
Solution:
<u>Note that:</u>
- Side₁ (Short side) = 15 meters
- Side₂ (Longer side) = 2(15) = 30 meters
- Perimeter = 2L + 2B
<u>Substituting the values into the expression:</u>
- 2L + 2B
- => 2(15) + 2(30)
- => 30 + 60
- => 90 m
The perimeter of the garden fence is 90 meters.
Disregard the 9x+3y in the pic. The answer is 3/4x-13/12=y
Answer:
1. Equilibrium solution: y= -3
2. Equilibrium solution y= ±1.414
Step-by-step explanation:
Thinking process:
The equilibrium solution can only be derived when 
1. Let's look at the first equation:

equating
to the expression
gives
y + 3 = 0
y = -3
Therefore, the equilibrium solution occurs at y = -3
2. Let's look at the second solution:

dividing each side by (t²-1) gives
1/(t²-1)
= (y²-2)/ (y²-4)
factorizing the right hand side gives:
at equilibrium:
, then
y² - 2 = 0
solving for y gives y = ±√2
= ±1.414
