plz help use full sentences

If you know the number of yards for a measurement, you can change that measure to meters by multiplying the number of yards by 0.9144.

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.

Answer 1

(a)
let M = metres and Y = Yards

M = 0.9144Y

(b) substitute Y = 7200 into the above function and round to 2 decimal places.

\[M = 0.9144 \times 7200\]

(c) you have an equation

2500 = 0.9144Y

divide both sides of the equation by 0.9144 to find the number of yards.

hope this helps

Answer 2

Meters = 0.9144 times Yards

M = 0.9144Y

So that's how campbell_st got part a)

Answer 3

oh ok

Answer 4

if you want to write that in function notation, you would replace M with F(Y), f(Y) or something like that to get

F(Y) = 0.9144Y

Answer 5

and the reason why there aren't many steps here is because it literally says "you can change that measure to meters by multiplying the number of yards by 0.9144."

Answer 6

so it's kinda given, which means not much work is to be done/shown

Answer 7

why would it be that??

Answer 8

part b) Plug in Y = 7200 to find M

M = 0.9144Y

M = 0.9144*7200

M = 6,583.68

So 6,583.68 meters are in 7200 yards

Answer 9

what do you mean?

Answer 10

i mean y would it be F(Y)

Answer 11

part c) plug in M = 2500 and solve for Y

M = 0.9144Y

2500 = 0.9144Y

2500/0.9144 = Y

2,734.03324584427 = Y

Y = 2,734.03324584427

Y = 2,734.03

So there are roughly 2,734.03 yards in 2500 meters

Answer 12

because function notation is like f(x), p(x), etc

the x is the input to the function

in this case, the Y (yards) is the input which is why it's f(Y) or F(Y), etc
