Answer:
Let r represent the radius of the smaller circle and R the radius of the larger circle.
Apply ratios: the radius of smaller circle to radius of larger circle, i.e.
r: R = 3 : 7.
I complete rotation = 360 degrees.
Part 1:
For one complete rotation of the smaller circle, the larger circle is rotated through: (3/7)*(360) = 154.3 degrees
Part 2:
For one complete rotation of the larger circle, the larger circle is rotated through: (7/3)*(360) = 840.0 degrees
This is equivalent to (840/360) = 2.3 rotations
Alternatively, use the ratios:
The number of rotations = R/r = 7/3 = 2.3 rotations

Answer:
$127.60
Step-by-step explanation:
If Lisa bought 30 shares of stock at $54.02 per share, total cost price will be:
30×$54.02
= $1620.6
If she then sold her shares at $58.19 per share, her total selling price will be:
30×$58.19
= $1745.7
Profit = selling price - cost price
Profit = $1745.7-$1620.6
Profit = $125.1
If her broker charges a 2% commission for all transactions, her total charge will be:
2% of $125.1
= $2.50
Her net gain = profit + broker's charge
= $125.1+$2.50
= $127.60
