Given circle Q with a measure of SR=120° and a radius of 9 feet, as shown below.

DiKsa [7]

Answer:

The arc length of the entire circle would be 2*PI*9

We need to know the arc length of 1/3 of the circle so we calculate

arc length = (2 * PI * 9) / 3

arc length = 2 * PI * 3

arc length = 6 * PI

arc length = 18.8495559215

1/3y+11=1/2y-3<br><br> What is y???

olga55 [171]

Answer:

$y=84$

Step-by-step explanation:

$\left(\frac{1}{3}\right)y+11=\left(\frac{1}{2}\right)y-3$

Use distributive property.

$\frac{1}{3}y+11=\frac{1}{2}y-3$

$\frac{1}{3}y+11-11=\frac{1}{2}y-3-11$

$\frac{1}{3}y=\frac{1}{2}y-14$

$\frac{1}{3}y-\frac{1}{2}y=\frac{1}{2}y-14-\frac{1}{2}y$

$-\frac{1}{6}y=-14$

$\left(-\frac{1}{6}y\right)\left(-6\right)=\left(-14\right)\left(-6\right)$

$y=84$
