Answer:
n = 0.38 rotation per second
Step-by-step explanation:
The device rotates according to the mathematical equation :
...(1)
Where n is the rotational speed and is measured in rotations per second (s).
r is radius of the circulator and is measured in meters (m).
We need to find the rotational speed when radius is 1.7 m. Put r = 1.7 m in equation (1).
Hence, the rotational speed is 0.38 rotation per second.
Answer:
$817.50
Step-by-step explanation:
Hello Matt7151!
To find the total amount, we will first need to find how much tax.
We can express 9% as the fraction .
× 750 = 67.50
So she's paying $67.50 sales tax.
