Answer:

18. 24%

19. $60.75

Step-by-step explanation:

18. You have to divide the change by the original number to find percent change. In this case you need to do 12/50 = 0.24. Therefore, the discount is 24%.

19. You have to multiply the original price by 0.25 to find how much the discount costs, then decrease the discount cost from the original price, which in this case is 90*0.25 = 22.50, you then have to decrease the sales price by 10% so you have to repeat the same thing with 0.1, so 67.5*0.1 = 6.75, 67.5- 6. 75 = 60.75. The final price is $60.75.

Question 9: Please help, what would be the length of the image of the segment GH?
shepuryov [24]

Answer:

<u><em></em></u>

  • <u><em>The length of the image of the segment GH would be 5 units.</em></u>

Explanation:

You can use the <em>center of dilation</em> as your origin of coordintes.

Thus, the <em>point H</em> would have coordinates (0,0) and the <em>point G</em> (-1,0).

A <em>dilation</em> multiplies the coordinates by the <em>scale factor</em>. Hence:

  • H = (0,0) → H' = 5 × (0,0) = (0,0)
  • G = (-1,0) → G] = 5 × (-1, 0) = (-5, 0)

Thus, the length of the image of segment GH would be the distance from 0 to -5 in a number line, which is 5.
