So real is 50000 times of the measured
so 6 inches turns to 6 times 50000=300000 inches

hoa many inches are ina mile


5280ft=1mile
12inches pe foot
5280 times 12=63360 inches

measured/inches per mile=miles
300000/63360=4.7348...

the one is listed as an ooption, 4.73 is the answer

1 / 50000 = 6/x
cross multiply
(1)(x) = (50000)(6)
x = 300000 inches = 8333.33 yds = 4.73 miles

M is proportional to the cube of r. when r=3m,m=216.when r=5 find the value of m
klio [65]

Answer:

The value of m is 1000 for r=5

Step-by-step explanation:

Given that m is proportional to the cube of r

It can be written as:

m \propto\ r^3

When the proportionality symbol is removed a proportionality constant is introduced in the equation.

Let k be the proportionality constant

m = kr^3

Given

r=3,m=216

Putting the values

216 = k(3)^3\\216 = k * 27\\k = \frac{216}{27}\\k = 8

The equation will now become

m = 8r^3

Putting r = 5

m = 8(5)^3\\m = 8 * 125\\m = 1000

Hence,

The value of m is 1000 for r=5

Answer:

\boxed{Fencing \: need \: to \: buy \: for \: the \: entire \: perimeter = \frac{40}{3}  \: yards}
