Answer:
240 students
Step-by-step explanation:
28/35=x/300
cross multiply to get 35x=300*28
divide both sides by 35 to get 240
Answer:
4.) 7 : 4 = 36[g] : x [g]
7 * x [g] = 4 * 36 [g]
7 * x [g] = 144 [g]
x [g] = 144 [g] / 7
x [g] ≈ 20, 57 [g]
5.) 3:2 250
3x + 2x =250
5x=250
x=50
3x=3*50=150
2x=2*50=100
(d(5) -d(3))/(5 -3) = (350 -126)/2 = 112 . . . . . meters/second
112 m/s; it represents the average speed of the object between 3 seconds and 5 seconds
Answer:
(-3, -1) (-2, 3)
(-2, 3) (-2, 3)
Step-by-step explanation:
Answer:
P(she selects the route of four specific capitals) = 1 in 2,686,320 or 3.72 x 10⁻⁷
Step-by-step explanation:
Assuming that the order at which she visits each of the four cities matters, the number of possible routes is the permutation of choosing 4 out of 42 capitals:

Therefore, the probability that she selects the route of four specific capitals is 1 in 2,686,320 or 3.72 x 10⁻⁷
