Answer:
72000 miles.
Step-by-step explanation:
Because we know each tire has been on the car for the same number of miles which means 1 tire can travel :4/5*90000 = 72000 miles.
Whenever a problem says "one number" and "another number" we can substitute x and y. for this we have x=2y+1 and xy=1. since we know the value of x (2y+1) we can substitute it for the other equation to get (2y+1)y=10. simplify to get 2y^2+y=10. from here you can do a few methods to solve this, but the simplest in my opinion is by factoring.
In order to factor it must be equal to 0, so we have 2y^2+y-10=0. We factor this and get y=5 (we also get y=-4 but it is an extraneous root). now we can plug that into either equation and find that x=2.
this means our two numbers are 5 and 2
6+5 = 11
99/11 = 9
9x6 = 54
so 54 cupcakes
Hope this helps, and May the Force Be With You!

We are given the speed of the shuttle as:
speed = 28,000 miles / hour
We know that:
1 mile = 5280 ft
24 hour = 1 day
Therefore by conversion:
speed = (28,000 miles / hr) * (5280 ft / 1 mile) * (24 hr
/ day)
speed = 3,548,160,000 ft / day
In 2 significant figures:
<span>speed = 3.5 x 10^9 ft / day</span>
<h2>Vertical distance gained from takeoff is 493.72 ft</h2>
Step-by-step explanation:
Refer the figure.
Horizontal distance = AB = 2800 ft
Angle = ∠B = 10°
We need to find AC that is h.
We have

Vertical distance gained from takeoff = 493.72 ft
