Tons needed to unload a freight train= 21×2.5 =52.5
number of 3.5-ton payload trucks needed to unload a freight train=52.5÷3.5 = 15
15 Trucks , Each With A 3.5-Ton Payloaf , Would be Needed To Do The Same Job.
The tangent of an angle is the opposite side divided by the adjacent side of the triangle, relative to the angle. By tan theta = 3, it means that, the adjacent side is thrice as long as the opposite side.
3a = o
Then, using Pythagorean's theorem:
25² = a² + o²
Substituting o,
25² = a² + (3a)²
25² = a² + 9a²
25² = 10a²
a = 7.9 cm
Then, 3(7.9) = o = 23.7 cm
So, the opposite side is 23.7 cm and the adjacent side is 7.9 cm.
Answer:
Goal = x
45000 = 9/10 * x
x = 45000 * 10/9 = 50000

X = 280. obteniendo luego 125 es 280!
First, We Have Find What Two Fifths Of 150. So, Divide 150 By Five To Find 1/5 Of 150.
150 ÷ 5 = 30.
Now, To Find 2/5 Of 150, Multiply 30 By Two. So:
30 * 2 = 60
So, 60 = 2/5 of 150.
So, subtract 60 from 150.
150 - 60 = 90.
So, now we need to add 35, because 35 people get back on.
90 + 35 = 125
There are 125 passengers when the train leaves.
