Jessica went shopping for a new watch. She found a watch that was originally priced at $50 on sale for $40. By what percent had
1 answer:
Answer:
20%
Step-by-step explanation:
We were given a price at $50 on sale for $40. To get the markdown percentage, take the amount of money you've discounted the merchandise at and divide it by the sales price.
$50 sweaters, you can put them on sale for $40.
The difference between these two prices is $10.
Now, we need to add the amount of which it was marked down
Therefore, the watch has been marked down by 20%.

Step-by-step explanation:
1.We choose a fish pond of radius 3 centered at (x, y) = (0, 3). The equation of the circle is ...
(x -0)^2 +(y -3)^2 = 3^2
x^2 +(y -3)^2 = 9
At this location it is easy to draw a radius along the y-axis to a point of tangency at the origin. That radius is a vertical line, so the tangent line will be perpendicular--a horizontal line.
A horizontal line through the origin has equation y = 0, and its point of intersection with this circle is (0, 0).

You haven't elaborated on what the lesson discussed, so we have no idea what steps you want included.
I could not answer 2 and 3 but maybe if i get it i will edit this paper and add it in.
