I strongly recommend that you enclose all those numerical fractions inside parentheses:

<span>(1/2)m -(3/4)n =16     Otherwise there's doubt whether you meant m/2 or 1/(2m)

Mult all 3 terms by 4 to elim. fractions:            2m -3n = 64

Now let n = 8:            2m - 3(8) = 64, or 2m = 88, or m = 44 (answer)</span>

Answer:

Radius: 8

Circumference: 50.27

πr^2 = Area of circle

201.06 = πr^2

divide by pi

201.06 / π = 63.9993857161 = 64

64 = r^2

Square root both sides to get radius.

\sqrt{64} = 8

r = 8

Circumference = π x diameter

Diameter = 2 x radius

Circumference = π x 16 = 50.2654824574 = 50.27

5 divided by 2,165 equals?
Mekhanik [1.2K]

answer:

1/433 (decimal: 0.002309)

step-by-step explanation:

5/2,165

= 1/433

to change 1/433 to decimal we'll divide the numerator by the denominator-

1÷433

=0.00230946882

so we're going to round to the ten-millionths place

5 or more raise the floor, 5 or less let it rest

4>5

so 0.002309

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!
