Completing the squares tells us exactly what square root we will need to calculate our answer.
Using the formula below you can find these answers:
![A(x-h)^2 + K = 0 (x-5)^ 2 = - K/A ](https://tex.z-dn.net/?f=A%28x-h%29%5E2%20%2B%20K%20%3D%200%0A%28x-5%29%5E%202%20%3D%20-%20K%2FA%0A)
Does this make sense?
Answer:
37 units
Step-by-step explanation:
The horizontal distance between these two points is 35 and the vertical is 12.
Treat these distances as the lengths of the legs of a right triangle whose hypotenuse we want to determine:
d^2 = 35^2 + 12^2 = 1369, so d = the distance between these two points = d = sqrt(1369) = 37 units
ANSWER
45 green bands
EXPLANATION
The ratio of red hair bands to green hair bands is
5 : 9
The total ratio is:
![9 + 5 = 14](https://tex.z-dn.net/?f=9%20%2B%205%20%3D%2014)
If there are a total of 70 hair bands,
Then the number of green bands
![= \frac{9}{14} \times 70](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B9%7D%7B14%7D%20%20%5Ctimes%2070)
Simplify
![= 9 \times 5](https://tex.z-dn.net/?f=%20%3D%209%20%5Ctimes%205)
Multiply
![= 45](https://tex.z-dn.net/?f=%20%3D%2045)
Therefore, there are 45 green bands.
Answer:
33
Step-by-step explanation:
take the total and then subtract by 34 to get 33
