The synchronous speed (rpm) equals 60 times the frequency divided by the number of pole pairs. For 50Hz, a two-pole motor will have a synchronous speed of 3000 rpm, a four-pole motor of 1500 rpm.
The actual speed is a few percent lower due to the slip of the asynchronous motor.
The slip increases with the torque, typical values are 5–10%. The rated speed for a four-pole motor at 50Hz will thus be something like 1360 rpm. At no-load, the slip is very small.
The media mix is the combination of media used and the frequency of advertising in each medium.

Explanation:
Answer:
She needs $150,000 to fund this perpetuity.
Explanation:
In this question we need to find the present value of this perpetuity. Because this is a growing perpetuity we will need to use the formula of present value of a growing perpetuity.
PV of growing perpetuity = Payment/ R-G
The payment is the current payment the perpetuity will pay which is 6,000, R is the interest rate which is 10% and G is the growth rate of the perpetuity which is 6%. Now we will input these values in the formula in order to find the present value of the perpetuity.
6,000/0.1-0.06
=6,000/0.04
=150,000
Although one would repair at the most time of 76 minutes, the other is at most 77.1 minutes. I would pick the second one because they may take longer by 1.1 minutes at most, they also included seconds, which seems more like an honest bid time.
