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:
a)The total amount of her weekly stock sales = $7,200
b) The total amount of her yearly stock sales = $350,000
Step-by-step explanation:
(a) Let us assume that the total a mount of her sales in a week = $m
Commission earned in a week = $288
Now, 4 % of her total sales = $288
or, 4% of ($m) = $288
⇒
or,
⇒ m = $7,200
Hence, the total amount of her weekly stock sales = $7,200
b) Let us assume that the total amount of her sales in a year = $k
The total amount of commission earned = $14,000
Now, 4 % of her total sales = $14,000
or, 4% of ($k) = $14,000
⇒
or,
⇒ k = $350,000
Hence, the total amount of her yearly stock sales = $350,000
