highlighters cost is $1.25 less than the binder. The total cost of the three supplies, with no tax, is $4.75. Write an equation to represent the solution.

check the picture below.

bearing in mind that the point of tangency, the green one there, is always a right-angle, then we get that much for the distance AB.

since the satellite can emit a signal at a speed of 186,000 miles/second, how long will it be to cover AB?  well, it'll just be AB/186000, which is about 0.1381 seconds.

and how long will it be to cover the distance AE?  well, it'll just be AE/186000, which is about 0.11828 seconds.

of course is quicker to AE since it's closer, so the difference for both distances will be AB - AE, which is about 0.01984121052328095721 seconds.



4)

if the satellite makes a revolution, or 2π, in 24 hours, and we know the satallite is orbiting at 22000+4000 or 26000 miles from the center of the Earth, thus its circular orbit has a radius of 26000, how many miles is that?

well, Circumference of a circle is C = 2πr, if r = 26000, then C = 2π(26000), so on those 24 hours it has covered 52000π miles.

how fast must it travel then?    \bf \cfrac{52000\pi }{24}~\cfrac{miles}{hours}\qquad \approx \qquad 6806.78~\frac{miles}{hour}

now if you need the rate in miles/seconds, bear in mind that an hour has 60 minutes and each minute 60 seconds, thus and hour has 60*60 seconds or 3600, thus its speed in miles/seconds will be 52000π/3600.

An 8 foot square floor is to be covered with square tiles measuring 8 inches on each side. If each tile costs 50 cents, how much
wariber [46]

9514 1404 393

Answer:

  (c) $72

Step-by-step explanation:

Each tile is 8/12 ft = 2/3 ft on a side. Then 8/(2/3) = 12 tiles will fit along each edge of the square area to be tiled. That is ...

  12 × 12 = 144

tiles will be needed to cover the area.

The cost of 144 tiles at $0.50 each is ...

  (144)($0.50) = $72.00
