Interval notation, I need help with this and I can't figure out how to do it!!
aliya0001 [1]

To find A∩B, you need to find the values that both data sets include, or where they overlap. Both data sets include the number range of 0 to 3. Because both data sets include 0, but set A does not include 3, the answer is [0, 3).

Lin is shopping for a couch with her dad and hears him ask the salesperson, "How much is your commission?" The salesperson says
Volgvan

Answer:

$467.77

Step-by-step explanation:

CHECK THE COMPLETE QUESTION

Lin is shopping for a couch with her dad and heard him ask the salesperson “how much is your commission?” The salesperson says that her commission is 5 1/2% of the selling price. A.How much commission will the salesperson earn by selling a couch for $495?

B.How much money will the store get from the sale of the couch?

From the question, the commission of the salesperson is 5 1/2 % , we can convert to improper fraction as 11/5%, then we can convert to decimal by dividing the numerator by denominator which is 5.5% , we can convert from percentage by saying(5.5%/100)

= 0.055

A)How much commission will the salesperson earn by selling a couch for $495?

His Commission will be

(0.055 x $495 )

= $27.23

B.How much money will the store get from the sale of the couch?

Since we know this Commission as $27.23, then the amount the store get from sale will be

(difference between the commission and the selling price)

($495.00- $27.23)

= $467.77

Find Y of the polygon
Deffense [45]
I that 'y' is 45 degrees because of alternate angles (I think its called).

If you look at the large triangle on the left where the corner angles are 35 and 80 and 20+an unknown angle. We can work out the missing angle by doing 180-80-35-20= 45. 

And so if we use the fact that alternate angle must be equal then y= 45 degrees (I think!)
