The probability of that is a 3 out of 15 chance he’ll pull out a nickel (hope this is right sorry if not)
Answer:
The first plane is moving at 295 mph and the second plane is moving at 355mph.
Step-by-step explanation:
In order to find the speed of each plane we first need to know the relative speed between them, since they are flying in oposite directions their relative speed is the sum of their individual speeds. In this case the speed of the first plane will be "x" and the second plane will be "y". So we have:
x = y - 60
relative speed = x + y = (y - 60) + y = 2*y - 60
We can now apply the formula for average speed in order to solve for "y", we have:
average speed = distance/time
average speed = 1625/2.5 = 650 mph
In this case the average speed is equal to their relative speed, so we have:
2*y - 60 = 650
2*y = 650 + 60
2*y = 710
y = 710/2 = 355 mph
We can now solve for "x", we have:
x = 355 - 60 = 295 mph
The first plane is moving at 295 mph and the second plane is moving at 355mph.
Answer:
Step-by-step explanation:
![f(1)=2/3\\f(2)=f(1)\times (3/2)=(2/3)\times(3/2)=1\\f(3)=f(2)\times (3/2) = 1\times (3/2) = 3/2\\f(4)=f(3)\times (3/2) = (3/2)\times (3/2) = 9/4\\f(5)=(f(4)\times (3/2) = (9/4)\times (3/2) = 27/8](https://tex.z-dn.net/?f=f%281%29%3D2%2F3%5C%5Cf%282%29%3Df%281%29%5Ctimes%20%283%2F2%29%3D%282%2F3%29%5Ctimes%283%2F2%29%3D1%5C%5Cf%283%29%3Df%282%29%5Ctimes%20%283%2F2%29%20%3D%201%5Ctimes%20%283%2F2%29%20%3D%203%2F2%5C%5Cf%284%29%3Df%283%29%5Ctimes%20%283%2F2%29%20%3D%20%283%2F2%29%5Ctimes%20%283%2F2%29%20%3D%209%2F4%5C%5Cf%285%29%3D%28f%284%29%5Ctimes%20%283%2F2%29%20%3D%20%289%2F4%29%5Ctimes%20%283%2F2%29%20%3D%2027%2F8)
So the first five terms are 2/3, 1, 3/2, 9/4, 27/8.
Answer:
46. 10+10+6+6=32
47. 10×6=60
Step-by-step explanation:
46. the formula the perimeter is length plus width, is this case 10+6. but that would only be 2 sides so you have to times that by 2... (10+6)×2
47. area equals length times width so in this case 10×6=60
