The resulting equation 75 = 75 is an identity; this tells that the two equations of the system are equivalent, this is they both represent the same function. So, Lian can conclude that (option c) both gyms charge the same monthly rate and the same membership fee<span>.</span>
Answer:
54 gallons
Step-by-step explanation:
Let x represent the volume of the full tank.
When the water tank is 30% full;
= 30% of x = 0.30x
when it is 20% empty:
= x - 20% of x = x - 0.20x = 0.80x
The difference is given as 27.
So, we can represent the question on an equation as;
0.80x - 0.30x = 27
Solving the equation, we have;
0.50x = 27
x = 27/0.50
x = 54 gallons
The tank can hold 54 gallons when it is full.
Answer:
Therefore,
The Central Angle is 48°.
Step-by-step explanation:
Given:
Circumference = 12 units

To Find:
Central angle = θ = ?
Solution:
If "θ" the central angle is in degree then arc of length is given by

Substituting the values we get

Therefore,
The Central Angle is 48°.
Answer: the answer is that causation cannot be determined from an observational study.
Step-by-step explanation:
Hello there!
The factorization form for the polynomial is: x(x + 2)(x +3)
The other factor is x + 2
I hope this helps!
