Use ratio and proportion
5.25/x= 82/100
cross multiply
82 x= 525
x= 6.4 miles
Hope this helps
Answer:
94.90
Step-by-step explanation:
Let
be the number of days spent at Tahoe and San Francisco, respectively.
We don't know the values of
and
yet, but we know that the holiday lasted 9 days:
![T+S=9](https://tex.z-dn.net/?f=T%2BS%3D9)
We also know that each day spent in Tahoe costed 350 and each day spent in San Francisco costed 475. So, the total cost of the holiday is the sum of the number of days muliplied by their cost:
![350T+475S=3650](https://tex.z-dn.net/?f=350T%2B475S%3D3650)
If we put the two equations together, we have the system
![\begin{cases}T+S=9\\350T+475S=3650\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7DT%2BS%3D9%5C%5C350T%2B475S%3D3650%5Cend%7Bcases%7D)
Which yields
![S=4,\quad T=5](https://tex.z-dn.net/?f=S%3D4%2C%5Cquad%20T%3D5)
Answer:
no solution
Step-by-step explanation:
#4 = B
Explanation= Because C&A are the same angle measurement, and the 90 angle is along a straight line making the other angle 90, and the triangles share the same side the postulate you can use is AAS because you can prove that the triangles share 2 common angles and 1 common side
#5 = B
Explanation= Because the triangles already have 1 congruent angle, and 1 congruent side the only thing left we can prove is that because the triangles mirror each other, they have congruent opposite angles (may be called vertical angles) as well so they have 2 angles and 1 side in common which tells you to use AAS
