Answer:
12 units
Step-by-step explanation:
- chords
and
are equidistant (7.2 units) from the center of the circle O. - Measures of the chords equidistant from the center of the circle are equal.
![\therefore m(chord\:\overline{AN}) =m(chord\:\overline{ML})](https://tex.z-dn.net/?f=%20%5Ctherefore%20m%28chord%5C%3A%5Coverline%7BAN%7D%29%20%3Dm%28chord%5C%3A%5Coverline%7BML%7D%29%20)

Answer:
Each apple costs $1.20 and each orange costs $1.
Step-by-step explanation:
Let x represent the number of apples and y represent the number of oranges.
For the fruit you bought, 5 apples and 4 oranges, we have 5x+4y. This costs $10. This gives us the equation
5x+4y = 10
For the fruit your friend bought, 5 apples and 5 oranges, we have 5x+5y. This costs $11. This gives us the equation
5x+5y = 11
Together we have the system
![\left \{ {{5x+4y=10} \atop {5x+5y=11}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B5x%2B4y%3D10%7D%20%5Catop%20%7B5x%2B5y%3D11%7D%7D%20%5Cright.)
We will eliminate x by subtracting the bottom equation from the top:
![\left \{ {{5x+4y=10} \atop {-(5x+5y=11)}} \right. \\\\-1y = -1](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B5x%2B4y%3D10%7D%20%5Catop%20%7B-%285x%2B5y%3D11%29%7D%7D%20%5Cright.%20%5C%5C%5C%5C-1y%20%3D%20-1)
Divide both sides by -1:
-1y/-1 = -1/-1
y = 1
Each orange costs $1.
Substitute this into the first equation:
5x+4(1) = 10
5x+4 = 10
Subtract 4 from each side:
5x+4-4 = 10-4
5x = 6
Divide both sides by 5:
5x/5 = 6/5
x = 1.2
Each apple costs $1.20.
7(h+k)(h+k- 3) if this is the answer you're looking for this is what I got so. Good luck
Answer:
29.4 °F
Step-by-step explanation:
There are ten thousands in 10,000. (Amazing, eh?) So, the temperature will drop by 10 × 1.9 °F = 19 °F.
A drop of 19 °F from 48.4 °F is ...
48.4 -19 = 29.4
The temperature at 10,000 ft will be 29.4 °F.
