A) If 9 students sharpen 18 pencils in 2 minutes,Then if the time is halved, it will take twice as many men to sharpen 18 pencils.Hence it will take 18 students to sharpen 18 pencils in one minute B) y & 1/x. Then y = K/x where K is our constant of proportionality.Then K = yx. When x = -64 and y = -16 then K = -64 * -16 = 1024. Option DC) When x = 3 y = 8. So for an inverse variation K as calculated from B = 3 * 8 = 24.Then when K = 24 and y = 6; we have 24 = 6x. Hence x = 4. Option A
Answer:

Step-by-step explanation:

Using the slope-intercept form (y=mx+b) the slope is:
1.66666666
Answer:
C.) 33.60
Step-by-step explanation:
OMP. = $56
D. = 25%
0.25 * $56 = $14
SP. = $56-$14=$42
CD. = 20% of Selling price
= 0.20 * $42 = $8.40
FSP. = $42-$8.40 = $33.60
The answer is 27.2. (meter is bigger)
1 yard = 91.44 centimeters, and 1 meter= 100 centimeters
91.44 * 120 = 10972.8
100*110 = 11000
