Answer:
its all smth if its a 150 all the side smtg
Answer:
Step-by-step explanation:
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
If d = 20 and C = 20π, then r = 10.
If d = 26 and C = 26π, <span>then r = 13.
</span>If r = 1/2 and C = π, <span>then d = 1.
</span>If r = 7 and C = 14π, <span>then d = 14.
</span>If r = 6 and C = 12π, <span>then d = 12.
</span>If r = 50 and C = 100π, then d = 100.
*Note, r= 1/2×d or d=2×r
