<h3>Answer:  176.6</h3>

Work Shown:

b^2 = a^2 + c^2 - 2*a*c*\cos(B)\\\\b^2 = 150^2 + 30^2 - 2*150*30*\cos(150)\\\\b^2 \approx 31194.22863406\\\\b \approx \sqrt{31194.22863406}\\\\b \approx 176.618879608211\\\\b \approx 176.6\\\\

a bottle of juice holds 3/8 gallon when it is full. if 1/3 of the juice has been poured out, how much juice is left in the bottl
taurus [48]
Let's get the denominators of both fractions to be the same before moving on, aka finding the least common multiple of the denominators.

8 and 3 have a LCM of 24. So, we have to multiply 1/3 by 8 and 3/8 by 3.

1/3 * 8/8 = 8/24

3/8 * 3/3 = 9/24

There is only 1/24 of juice left in the bottle if the remaining amount of juice has 1/3 poured out.

Hope that helped.

tigry1 [53]

Answer:

1. Construct a segment XY on the a sketch.

2. Elsewhere on the sketch, draw a line and create a point on the line . Label the point P.

3. Select point P and line segment XY.  Construct circle by center and radius.

4. Select the circle and line, then construct point of intersection. Label one of the points of intersection point Q.

5. Select point P and point Q.  Construct segment PQ.

6. Select the circle, line, and other point of intersection.  Hide objects.  Only segment XY and segment PQ should be visible on the sketch.

7. Try dragging point X.  Segment PQ should lengthen and shorten as segment XY does.
