Answer:

.90(85.00) would give the same result

Step-by-step explanation:

Rhonda is using the total cost of the item ($85.00) multiplied by the discount (10%) to find the total discount: 85 x 0.10 = 8.50. Once Rhonda subtracts the discount ($8.50) from the total: $85 - $8.50 = $76.50. The other way to look at the problem, is that Rhonda is only paying for 90% of the total cost of the items, instead of 100% since she is receiving the 10% discount. So, she would get the same final total by multiplying the cost of the items ($85.00) by 90%, or 0.90.

andre [41]

Answer: See below

Step-by-step explanation:

Both will use the straight edge to make segments and use the compass to take measurements.

They will draw a line with a straight edge and will find a starting point, then with a compass:

Annie will take the measurement of the segment and, from the starting point of the line, will put in the other point to obtain the congruent segment.

But in Jaymie's case, she will need to do a little more work with a compass because to build congruent angles, she will need to make a semi-circle in the original angle and transfer this measurement to the new line to construct the angle.
