37. B: Negative inverse, the product of the gradients is -1
38. C: decreases
39. B: the sum of all divided by 9
Answer:
greater than sign (>)
Step-by-step explanation:
1.45 can be rewritten as a fraction (1 and 1/20). 16/11 can be rewritten as 1 and 5/11. The greater the denominator, the smaller the number. So, with the previous sentence in mind, 16/11 (1 and 5/11) is greater than 1.45 (1 and 1/20).
1. B. The retail price would be the purchase price plus the markup.
So p+.40p = 1.40 p = 1.4 p. (p is really 1 p)
C. You would multiply: 1.4(56) = $78,40
D. You could multiply .4p = .4(56). OR subtract: 78.40-56 = $22.40
2. Done
3. 10(.35) = $3.50 —— 10+3.50=$13.50
4. 40(.25) = $10 ———- 40+10=$50
5 Done
6. $30.50/30% markdown 30.50(.30) = $9.15; 30.50-9.15= $21.35
7. $105/75% markdown 105(.75) = 78.75; 105-78.75= $26.25
8. $325/15% markdown 325(.15) = 48.75; 325-48.75= $276.25
9. C/40%markup Total retail:.40c + c = 1.40C
no because she turned it only 90 degrees not 180.
180 would be a mirror reflection

So sorry if its incorrect!
