On Black Friday, Amazon. com featured an Echo 2nd Generation for $42 normally selling for $72. Calculate the dollar markdown and the markdown percent based on the selling price to the nearest whole percent.

dollar markdown would be $30, dollar markdown percentage would be

Step-by-step explanation:

Dollar markdown is $72-$42=$30

Dollar markdown percentage is ($30(price drop))÷($72(original price)) which comes to be 41%(nearest whole percentage)

I hope this helps you =)

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
