notebooks cost $1.20 each this weekend they will be on sale for $0.80 what percentage off of the orignal sale

40 % off

Step-by-step explanation:

First you are going to 1.30, then divided that by 0.80

33%

Step-by-step explanation:In the question it is already given that the actual cost of each notebook is $1.20. For the weekend, the notebooks would sold at a discounted rate of $0.80

The amount of discount during the weekend = (1.20 - 0.80) dollars

                                                                      = 0.40 dollars

So the amount of discount given during the weekend is $0.40

Now we need to find the percentage of discount given during the weekend.

Then

Percentage of discount during the weekend = (0.40/1.20) * 100

                                                                      = 0.33 * 100

                                                                      = 33

Then the percentage of discount given is 33%.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
