Answer:
No, Mai's reasoning is incorrect
Step-by-step explanation:
They are actually going the same speed because their centimeter per second ratio is the same. this can be found by dividing them both down, divide the slug by three and the snail by 6 and they both end up the same centimeter/second ratio. (1:1)
Sorry idk how to explain it good but do you get it?
Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(-8,-2)....x1 = -8 and y1 = -2
(4,1)......x2 = 4 and y2 = 1
now we sub and solve
d = sqrt ((4 - (-8)^2 + (1 - (-2)^2)
d = sqrt ((4 + 8)^2 + (1 + 2)^2)
d = sqrt(12^2 + 3^2)
d = sqrt (144 + 9)
d = sqrt 153
d = 12.37 units <=== (and that is rounded)
Answer:
357 minutes
Step-by-step explanation:
I subtracted 9 cents/minute from the 23 cents/minute to get 14 cents to get the difference between the two per minute charges. I then divided the monthly cost of $49.95 by .14 to get 356.79... So if you used 357 minutes in a month, the second plan would be 3 cents cheaper at $82.08 (.09 x 357= 32.13 + 49.95), vs. the first plan costing $82.11 (.23 x 357). At 356 minutes the first plan would still be cheaper.
Answer:
(0.75) to the 3rd power is 0.421875
then multiply that by 240 and you get 101.25
rounded to the nearest 10th would be 101.3
