Answer: ![\frac{\sqrt{65}}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B65%7D%7D%7B4%7D)
Step-by-step explanation:
By the Pythagorean theorem, the unknown side has length
![\sqrt{9^{2}-4^{2}}=\sqrt{65}](https://tex.z-dn.net/?f=%5Csqrt%7B9%5E%7B2%7D-4%5E%7B2%7D%7D%3D%5Csqrt%7B65%7D)
Therefore,
![\tan \theta=\boxed{\frac{\sqrt{65}}{4}}](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%3D%5Cboxed%7B%5Cfrac%7B%5Csqrt%7B65%7D%7D%7B4%7D%7D)
Answer:
the temperature drops 2 degrees F
Step-by-step explanation:
So the first one is 1 square meter of ceiling, and it says 1 square meter of cieling is 10.75. <em>So the first one is just that, 10.75</em>
The second one says 10 square meters, so just multiply 10.75, by 10.
In which case you get <em>107.5.</em> So that's the answer.
Third one, it gives you how many ceiling tiles you have. So you divide the 100 tiles by 10.75, which gives you 9.30232558, which becomes <em>9.3</em>
I'm sure you can figure out the last one.
Answer:
Step-by-step explanation:
Since the number of bagels sold already is 47, the total number of bagels sold will be b+47. The revenue from each sale is $0.85, so the total revenue will be ...
A = 0.85·(b +47)
This equation can be written in different forms, but this satisfies the requirement for "an equation."
__
Since b is the number of addition bagels, when 122 additional bagels are sold, the value of b is 122. Then the equation becomes ...
A = 0.85·(122 +47)
A = 0.85·169 = 143.65
Revenue will be $143.65 when 122 additional bagels are sold.
