Answer: ![a=10](https://tex.z-dn.net/?f=a%3D10)
Step-by-step explanation:
1. You have the following equation given in the problem above:
![\frac{a}{10}-\frac{1}{2}=\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B10%7D-%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B1%7D%7B2%7D)
2. You must add 1/2 to both side of the equation, then:
![\frac{a}{10}-\frac{1}{2}+\frac{1}{2}=\frac{1}{2}+\frac{1}{2}\\\frac{a}{10}=1](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B10%7D-%5Cfrac%7B1%7D%7B2%7D%2B%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B1%7D%7B2%7D%2B%5Cfrac%7B1%7D%7B2%7D%5C%5C%5Cfrac%7Ba%7D%7B10%7D%3D1)
3. Now, you must multiply each side of the equation given by 10, therefore, you obtain the following result:
![\frac{a}{10}*10=1*10\\a=10](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B10%7D%2A10%3D1%2A10%5C%5Ca%3D10)
I believe the answer is 11ft
Answer:
30
Step-by-step explanation:
Substitute X with 7 since X=7 so 2(7+8). Follow order of operations and 7+8=15 and the multiply 15 by 2 to get your final answer 30.
Answer:
C; ![\frac{5\pi }{3}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Cpi%20%7D%7B3%7D)
Step-by-step explanation:
According to the unit circle, the ordered pair for
is ![(\frac{1}{2} ,\frac{-\sqrt{3} }{2} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B2%7D%20%2C%5Cfrac%7B-%5Csqrt%7B3%7D%20%7D%7B2%7D%20%29)
Sin is the y-value on the unit circle while Cos is the x-value on the unit circle, so
is the angle that fits the critera
