Answer: hello the answere is B
Step-by-step explanation:
I don't know about estimate but the answer is 7 7/8 hours
you would do 7.8 times 0.5 and would get 3.9. You would add 7.8 and 3.9 and get 11.7 That is your answer

Answer:
Part 1) ![x=\frac{10\sqrt{3}}{3}\ units](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B10%5Csqrt%7B3%7D%7D%7B3%7D%5C%20units)
Part 2) ![y=5\ units](https://tex.z-dn.net/?f=y%3D5%5C%20units)
Step-by-step explanation:
step 1
Find the value of x
In the right triangle of the figure
---> opposite side angle of 30 degrees divided by the hypotenuse
Remember that
![sin(30^o)=\frac{1}{2}](https://tex.z-dn.net/?f=sin%2830%5Eo%29%3D%5Cfrac%7B1%7D%7B2%7D)
substitute
solve for x
![x=\frac{5\sqrt{3}}{3}(2)](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5%5Csqrt%7B3%7D%7D%7B3%7D%282%29)
![x=\frac{10\sqrt{3}}{3}\ units](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B10%5Csqrt%7B3%7D%7D%7B3%7D%5C%20units)
step 2
Find the value of y
In the right triangle of the figure
---> adjacent side angle of 30 degrees divided by the hypotenuse
we have
![x=\frac{10\sqrt{3}}{3}\ units](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B10%5Csqrt%7B3%7D%7D%7B3%7D%5C%20units)
![cos(30^o)=\frac{\sqrt{3}}{2}](https://tex.z-dn.net/?f=cos%2830%5Eo%29%3D%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D)
substitute
![y=(\frac{\sqrt{3}}{2})(\frac{10\sqrt{3}}{3})](https://tex.z-dn.net/?f=y%3D%28%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D%29%28%5Cfrac%7B10%5Csqrt%7B3%7D%7D%7B3%7D%29)
![y=5\ units](https://tex.z-dn.net/?f=y%3D5%5C%20units)
