F it rose 10% that means that it is now worth 110% of what it was a year ago. So set up an equation: 297 = 110% of x297 = 1.1 x270 = x So it was worth $270 a year ago.

Answer:
59.16 units
Step-by-step explanation:
Given that,
The length of rectangle, L = 13
The breadth of the rectangle, B = 6
The perimeter of the shaded region = perimeter of rectangle - 2(perimeter of semicircle)
![P=13\times 6-[2\times \dfrac{2\pi r}{2}]\\\\=78-2\pi r\\\\=78-2\times 3.14\times 3\\\\=59.16](https://tex.z-dn.net/?f=P%3D13%5Ctimes%206-%5B2%5Ctimes%20%5Cdfrac%7B2%5Cpi%20r%7D%7B2%7D%5D%5C%5C%5C%5C%3D78-2%5Cpi%20r%5C%5C%5C%5C%3D78-2%5Ctimes%203.14%5Ctimes%203%5C%5C%5C%5C%3D59.16)
So, the perimeter of the shaded region is 59.16 units.
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
divisionLet'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.

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!
