Substitute the value 350 in for your velocity:
350 = 20 * sq rt(273+t)
divide both by 20 --> 17.5 = sq rt(273 +t)
square both to cancel out the sq rt --> 306.25 = 273 +t
then just subtract 273 from both to get 33.25 = t
Answer:
c none of the above.
Step-by-step explanation:
c none of the above. Try substituting values of g and h.
Speed = distance/time
distance = speed * time
let x = time covered by running
15 = run distance + walk distance
15 = 9(x) + 3(3-x)
15 = 9x + 9 - 3x
15 - 9 = 6x
6 = 6x
x = 1 hour
Therefore:
Running distance = speed * time
RD = 9km/hr * 1 hr
RD = 9km
4:1
(grapes);(rasins)
4:1
x:3000
so you then cross multiply
1·x=4·3000
multiply,
x=12000
so the answer is it takes 12000 pounds of grapes to make 3000 pounds of raisins
