Answer:
141.37 cm
Step-by-step explanation:
If we're going off of the blue shaded region, the area of the full circle is 254.47 cm^2. Then we calculate the area of the inner circle. This gives you 113.1. Now you must subtract the area of the inner circle by the area of the outer circle. 254.47-113.1. This gives you 141.37, which should be your answer.
Answer:
Maricopa's Success invests $25,000 in stocks, $40,000 in bonds, and $10,000 in CDs.
Step-by-step explanation:
a = Stocks
b = Bonds
c = CDs
a + b + c = 75000
b = 30000 + c
a = 75000 - c - 30000 - c = 45000 - 2c
0.065(45000 - 2c) + 0.044(30000 + c) + 0.0225c = 3610
2925 - 0.13c + 1320 + 0.044c + 0.0225c = 3610
0.0635c = 635
c = 10000
So b = 40000 and a = 25000

Answer:
P = 70 cents per muffin
Step-by-step explanation:
It says to find the price when the supply and demand are equal, so you have to set the two equations equal to each other.
7700/p = 3p-100.
It seems to me that the best way to solve this would be to set up a quadratic equation.
If you multiply both sides by p and then subtract 7700, you get the following:
0=3p^2 -100p -7700
I wrote a program to solve this, and I got the answers p= 70 and -36.67.
Obviously, a negative number doesn’t work in this situation, so the answer is 70 cents per muffin. To check this, you can plug it back into the equation:
7700/70=3(70)-100
110=110
I would go with B, one hundred ninety five dollars.
Hope that this would help you..
