a. Write a function rule that relates meters to yards.

b. How many meters are equivalent to 7,200 yards? Round your answer to the nearest hundredth, if necessary.

c. How many yards are equivalent to 2,500 meters? Round your answer to the nearest hundredth, if necessary.

"change that measure to meters by multiplying the number of yards by 0.9144.
"

Do that.

anonymous · Answer

makyyy soo do i say 0.9144x

or something like that.?

tkhunny · Answer

Why make it difficult.  How about:

Yards * 0.9144 = Meters

anonymous · Answer

yeaa that does look much more simple lol

anonymous · Answer

that would be the answer to question a.?

tkhunny · Answer

Okay, now tackle b.

anonymous · Answer

that i have no idea how to do. where do i start.?

tkhunny · Answer

How can you have no idea?  Did you write the answer to a.?

Yards * 0.9144 = Meters

THERE is a great idea.  What additional information are you given?

anonymous · Answer

7,200 yards

tkhunny · Answer

Okay, substitute 7200 into your functional equation and solve for meters.

anonymous · Answer

i got 6583.68

tkhunny · Answer

Perfect.  Move on to c.

Do NOT say you have no clue.  That is incorrect.  You DO have a clue.

anonymous · Answer

i would divide this beccause its going backwards right.?

tkhunny · Answer

You substitute the given information and do whatever it takes to solve.  It takes division in this case.

anonymous · Answer

its not looking right in my calc. it says 

2734.033245844269

tkhunny · Answer

That might be a few excessive decimal places, but I think you have it.

anonymous · Answer

so do i not put everything after the decimal.?

tkhunny · Answer

We can talk about precision and significant figures some other time.  For now, read the problem statement.  It wants the "nearest hundreth".  This will take some rounding.

anonymous · Answer

2700

tkhunny · Answer

No, that was the nearest "hundred".  You need the nearest "hundredth".  That's two decimal places.

anonymous · Answer

umm i dont know :| 

2734.03.

anonymous · Answer

am i close.?

tkhunny · Answer

Not only close, but DONE!
