Answers

Answer:

x = -2

Step-by-step explanation:

6 + 3(10x-22)

3 * 10x = 30x

30x = -60

-60/30 = -2

Ky wants to buy three shirts, which were originally priced at $49.96 each. The store will discount the price of the 3rd shirt by 50% off and apply a %7.1 tax to the total cost of all three shirts. Including the tax, what will be the mean cost of each shirt?

Answers

9514 1404 393

Answer:

  $44.49

Step-by-step explanation:

The total cost before tax will be ...

  $49.96 +49.96 + 0.50(49.96) = $124.90

With tax added, the cost is ...

  $124.90 × 1.071 = $133.77

Then the average cost per shirt for the 3 shirts is ...

  $133.77/3 = $44.59

The mean cost of a shirt is $44.59.

the answer is $44.49

can someone teach me how this goes? geometry , inscribed angles but circles

Answers

Answer:

60

Step-by-step explanation:

So basically all you need to know for this one is that when there is an inscribed angle, the angle measure is 1/2 of the measure of the arc for that angle.

That might sound confusing, but an example from the picture is that angle ABC will be half of arc AC. This means that angle ABC is 1/2 of 120 = 60 degrees.

The answer is 60 degrees.
