Angle QPS is an inscribed angle. Arc QS is the intercepted arc of that angle. The rule is that the intercepted arc is twice its angle measure. P measures 20 degrees, so arc QS measures 40 degrees. It just so happens that angle QTS is ALSO an inscribed angle intercepting arc QS. So angle QTS measures the same as angle P, 20 degrees. That's a. For b., we already stated the rule and figured out that minor arc QS is 40 degrees. For c., major arc QTS is 360 (the measure around the outside of a circle...EVERY circle in the world) minus the minor arc of 40. So major arc QTS measures 360 - 40 which is 320 degrees. There you go!

Answer:

1.x=15

2.<A=29

Step-by-step explanation:

(2x-1)+(3x+9)+(6x+7)=180

2x-1+3x+9+6x+7=180

11x+15=180

11x=180-15

11x=165

x=165/11

x=15

For every 9 minutes of music Shawn listens to, Greg listens to 4 minutes of music. How many times more minutes of music does Sha

Vaselesa [24]

Hello.

The mathematical concept of this problem is basic once you get down to it. The question asks, "How many times more minutes does Shawn listen to than Greg?"

Remember the "How many" rules:
· "How many more" suggests subtraction
· "How many times" suggests division

Let's also take a look at our opening sentence: "For every 9 minutes of music Shawn listens to, Greg listens to 4 minutes of music." This means we can set it up as a fraction, as we have the phrase "For every" in our sentence. So, let's do that.

$\frac{9}{4}$ is our fraction;
To simplify, we need to divide our numerator (the number on the top) by our denominator (the number on the bottom).
9 / 4 = 2.5

This is our rate, or how many times more music Shawn listens to than Greg.

Your answer is: "Shawn listens to 2.5 times more music than Greg."

I hope this helps!
