Answer:

arc length =11

Step-by-step explanation:

The circumference is 12 which is equal to 2 * pi *r

arc length = 12 * 330/360

arc length = 12 * 11/12

arc length =11

Answer:

The answer to the question provided is 14.

Step-by-step explanation:

》The Distance Formula:

$d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }$

》Plug in.

$d = \sqrt{( - 5 - 9)^{2} + (3 - 3) ^{2} } \\ d = \sqrt{( - 14)^{2} + (0) ^{2} } \\ d = \sqrt{196 + 0} \\ d = \sqrt{196} \\ d = 14$

Bess [88]

Answer:

45 and 72

Step-by-step explanation:

Let the ages be r and m

We have:

r + m = 117
5r = 9 + 3m

Substitute m in the second equation and solve for r:

m = 117 - r
5r = 9 + 3( 117 - r)
5r = 9 + 351 - 3r
5r + 3r = 360
8r = 360
r = 360/8
r = 45

Then m is

m = 117 - 45 = 72
