working as a waiter, Michael earns $6.50 per hour plus tips. last night he received $36.50 in tips and earned a total of $65.75. how many hours did he work

Answer: she will be able to spend $980 on the bike.

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $800

r = 7% = 7/100 = 0.07

n = 1 because it was compounded once in a year.

t = 3 years

Therefore,.

A = 800(1 + 0.07/1)^1 × 3

A = 800(1 + 0.07)^3

A = 800(1.07)^3

A = $980

Considering it's own equation, the circumference of the circle will be increased by a factor of 7.

What is the circumference of a circle?

The circumference of a circle of radius r is:

Since the radius is elevated to power 1, if it is multiplied by a factor of 7, the circumference of the circle will also be increased by a factor of 7.

Final answer:

The question provides two equations involving the variable f. By isolating f in these equations, we derive two possible values for f. The minimum value for f is the smaller of these two derived values, which is -5/3.

Explanation:

To solve this we can use the principle that if two different values of f multiply with different numbers to equal different constants, we can set up a system of equations to find those values of f.

The given equations are f×3=-5 and f×1=2. Let's denote f×1 as f₁ and f×3 as f₂.

• From f×1=2, we get f₁=2/1=2
• From f×3=-5, we get f₂=-5/3

So, the minimum value of f, that is f_min would be the smaller of f₁ and f₂. As -5/3 is smaller than 2, f_min = -5/3.
