Nataly [62]

Answer:

17.2 in

Step-by-step explanation:

The formula for arc length is s = rФ.  Here we are to find r.  Solving this formula for r, we get:

r = s/Ф

So, in this problem, r = (9 in) / (π/6) = 54/π in ≈ 17.2 in

What percent of $5 is $3.75?
nataly862011 [7]

Answer:

75%

Step-by-step explanation:

We can use the formula \frac{is}{of}=\frac{percent}{100}

  • "of" is 5
  • "is" is 3.75
  • We will denote "percent" as x since that is what we are solving for

Now we just need to plug in the known values and solve for x

  • \frac{3.75}{5}=\frac{x}{100}
  • Cross multiplying we get (5)(x) = (3.75)(100)
  • Then simplifying we get 5x = 375
  • Dividing by 5 we get x = 75%

$3.75 is 75% of $5
