2.1-2p= -4.7
they said the difference of 2.1 and twice a number p. which I'm assuming letter p, but anyway. difference means subtraction and twice mean multiplication so 2p
that's why we have 2.1-2p= -4.7
Answer:
56.38mph
Step-by-step explanation:
I attached a Graphic to make easier understand this problem.
However it is just a trigonometric problem, where
![cos \theta = \frac{V}{u} \theta](https://tex.z-dn.net/?f=cos%20%5Ctheta%20%3D%20%5Cfrac%7BV%7D%7Bu%7D%20%5Ctheta)
Where \theta is the angle between the line of lecture and the trayectory from the Auto
V= 'Real' Velocity
u = Velocity from Radar.
Solving to V;
![V= u*cos\theta](https://tex.z-dn.net/?f=V%3D%20u%2Acos%5Ctheta)
![V= 60 * cos 20](https://tex.z-dn.net/?f=V%3D%2060%20%2A%20cos%2020)
![V= 56.38mph](https://tex.z-dn.net/?f=V%3D%2056.38mph)
Answer:
Below in bold.
Step-by-step explanation:
Work in times to fill 1 pail:-
tap A takes 55/4 seconds
tap B takes 50/3 seconds
Let time to fill one pail be x when filling together, then:
3/50 + 4/55 = 1/x
165x + 200x = 55*50
x = 2750 /(365) = 7.5342 seconds
To fill 16 pails it takes 7.5342* 16
= 120.55 seconds
= 2 minutes 1 second to the nearest second..
