\frac{1192}{7}
Convert 149 to a fraction (\frac{149}{1}). 
To divide by a fraction, use the inverse or reciprocal (switch the numerator and denimoninator).
The reciprocal of \frac{7}{8} [tex] is [tex] \frac{8}{7}. 
So, multiply those two fractions together (149 x 8 = 1192) (1 x 7 = 7) to get \frac{1192}{7}

Can someone help me <br> 14. Determine the arc length. Give your answer to two decimal places.
Paul [167]

Answer:

19.48 m

Step-by-step explanation:

The formula that is used to find arc length is:

arc length = 2πr (\frac{angle}{360})

In this question, r = 9m and the angle (θ) = 124°. Substitute the values into the formula.

arc length = 2 × π × 9 ×(\frac{124}{360})

= 2 × π × 9 × 0.3444

= 19.48 m

The polygons in each pair are similar. Find the missing side length / first one has 4 &amp;x and second one has 12&amp;18
sergiy2304 [10]

Answer:

x = 6

Step-by-step explanation:

To find the missing side, write a proportion using side lengths from each similar shape. A proportion is an equation that sets equal two ratios.

\frac{4}{12}=\frac{x}{18}

Find x by cross multiplying numerator and denominator of each fraction.

4(18) = 12x

72 = 12x

6 = x
