Answer:
640 litres

1) Here, as the two angles are same, it would be isosceles triangle with two equal sides, so x = 5
y = x√2
y = 5√2 or 7.05
In short, Your Answers would be: x = 5 & y = 7.05
2) We know, Sin Ф = P / H
Sin 30 = 27 / H
1/2 = 27 / H
H = 27 * 2
H = 54
In short, Your Answer would be 54 Feet
Hope this helps!
Answer:
8.93 lbs
Step-by-step explanation:
We write the kinematics equations
a
vf = a * t + vo
rf = (1/2) * a * t ^ 2 + vo * t + ro
We have then
For the truck:
a = 0
vf = vo
rf = 45t
For the car:
a = 0
vf = vo
rf = 60 * (t-15)
Matching rf:
45t = 60 * (t-15)
Clearing t:
45t = 60t-900
60t-45t = 900
15t = 900
t = 900/15 = 60h
Answer:
it will take for the car to catch up with the truck 60h
It's called laissez-faire economics and is essentially what capitalism is built on.
