265÷106=2.5,2.5×,100=250, so before tax, the cost would be 250$
I think this is the answer to what u r trying to say: so u would take one domino ex.) top:5 bottom: 8. u would match that with true sentences by doing the top number plus the bottom number. ex.) 5 + 8 = 13.
Answer:
3.9 units
Step-by-step explanation:
We are given that,
Time taken by each swing = 2.2 seconds
The pendulum formula is given by,
, where T is the time taken and L is the length of the swing.
So, we have,
![2.2= 2\pi \sqrt{\frac{L}{32}}](https://tex.z-dn.net/?f=2.2%3D%202%5Cpi%20%5Csqrt%7B%5Cfrac%7BL%7D%7B32%7D%7D)
i.e. ![\frac{2.2}{2\pi}=\sqrt{\frac{L}{32}}](https://tex.z-dn.net/?f=%5Cfrac%7B2.2%7D%7B2%5Cpi%7D%3D%5Csqrt%7B%5Cfrac%7BL%7D%7B32%7D%7D)
i.e. ![(\frac{2.2}{2\pi})^{2}=\frac{L}{32}](https://tex.z-dn.net/?f=%28%5Cfrac%7B2.2%7D%7B2%5Cpi%7D%29%5E%7B2%7D%3D%5Cfrac%7BL%7D%7B32%7D)
i.e. ![L=32\times (\frac{2.2}{2\pi})^{2}](https://tex.z-dn.net/?f=L%3D32%5Ctimes%20%28%5Cfrac%7B2.2%7D%7B2%5Cpi%7D%29%5E%7B2%7D)
i.e. ![L=32\times \frac{4.84}{4 \pi^2}](https://tex.z-dn.net/?f=L%3D32%5Ctimes%20%5Cfrac%7B4.84%7D%7B4%20%5Cpi%5E2%7D)
i.e. ![L=32\times \frac{1.21}{\pi^2}](https://tex.z-dn.net/?f=L%3D32%5Ctimes%20%5Cfrac%7B1.21%7D%7B%5Cpi%5E2%7D)
i.e. ![L=\frac{38.72}{9.87}](https://tex.z-dn.net/?f=L%3D%5Cfrac%7B38.72%7D%7B9.87%7D)
i.e. L = 3.923 units
So, rounded to tenths, the length of the swing is 3.9 units.
Y-(-5)/x-(-18)=-2/9
9y+45=-2x-36
9y=-2x-36-45
y=-2/9x-9
The answer to this problem will be A fraction
