Stacy bought a skateboard at a local sporting goods store. The skateboard was on sale for 10% off the original price. The store

yarga [219]

If the original price is x, then x-0.10x=0.9x (which is a 10 percent off discount - 10 percent = 0.10 if you move the decimal spot 2 places over), then 10% of 0.9x is not 0.10x due to that 0.1/0.9=1/9, not 1/10. 1/10 of 0.9 is 0.09, so
0.9-0.09=0.81 of the original price

If the 10% sales tax was added first, it wouldn't matter since you're still getting 10% twice either way

A parallelogram is formed by the supports that attach a basketball backboard and rim to the wall. The angles change as the baske

irina [24]

The measure of angle BCD is 32 degrees

<h3>How to determine the value of BCD?</h3>

The image of the parallelogram that completes the question is added as an attachment.

The given parameter is:

m<DAB = 32 degrees

From the attached image, we can see that BCD and DAB are opposite angles.

Opposite angles of a parallelogram are equal.

So, we have:
