Answer:
225 centimeters.
Step-by-step explanation:
To solve this, we need to find half of 4.5. We can do this by dividing 4.5 by 2. When we do this, we get 2.25. This means Noah's plane flew 2.25 meters, but we aren't done yet. Now, we need to find how much farther Aaron's plane flew. We can do this by subtracting 2.25 from 4.5. From this, we get 2.25. That last step wasn't really necessary. Now, we need to convert 2.25 meters to centimeters, we can do this by multiplying 2.25 by 100. When we do this, we get 225. This means Aaron's plane flew 225 centimeters farther than Noah's plane.
Answer:
a) 9
b) -3
Step-by-step explanation:
a)
|9+x|=2x
9 + x = 2x
- x -x
---------------
9 = x
b)
|x+6|=2x+9
x +6 = 2x +9
-x -x
6 = x + 9
-9 -9
--------------
-3 = x
<span>t = 0.61 or 8.79
The equation you're giving is very badly formatted, but it looks like a variant of h = 47T - 1/2 AT^2 with the 1/2 already factored out and using an A of 10 m/s^2 which is close enough to the actual value of 9.8m/s^2. So I'll use the equation of h = 47t - 5t^2.
You're looking for a height of 27 meters. So let's assign that value:
h = 47t - 5t^2
27 = 47t - 5t^2
And we can manipulate that to make a quadratic equation. So:
27 = 47t - 5t^2
0 = 47t - 5t^2 - 27
-5t^2 + 47t - 27 = 0
Using the quadratic formula, we can find the roots at 0.61466 and 8.78534
So the rocket is at 27 meters at t = 0.61 seconds as it's going up and at t = 8.79 seconds as it's going back down.... Assuming of course, you don't have a parachute.</span>

Answer:
Jacob can rent a car for 6 days with $20 left to spare.
Step-by-step explanation:
200 - 30 = 170
170 / 25 = 6.8
25 * 6 = 150
170 - 150 = 20
