Answer:
It would be 2
Step-by-step explanation:
Since they are looking for only 1 significant fig. you would round the number that would make this correct, for example:
You would look at 1.7 and ignore the others...
7 is greater than 5 so it'll affect the 1
And that how you get 2 : )
Answer:Cost per box: $95.94 ÷ (b)
Cost per tile: [$95.94 ÷ (b)]÷ (t)
First, we are trying to find the cost of each crate. Since the whole order was $95.94, we have to divide. The answer to the cost per box is $15.99.
Second, we are trying to find the cost of each of the tiles in the crates. Since they are in each crate, we divide the crate price from the tiles. The answer of the cost per tile is $.80.
Hope this helped you out!
Answer:
![x = 0.175\cdot (1-\cos 4\cdot \theta)](https://tex.z-dn.net/?f=x%20%3D%200.175%5Ccdot%20%281-%5Ccos%204%5Ccdot%20%5Ctheta%29)
Step-by-step explanation:
Let use the following trigonometric identities:
![\sin^{2}\theta = \frac{1-\cos 2\cdot \theta}{2} \\\cos^{2}\theta = \frac{1+\cos 2\cdot \theta}{2}](https://tex.z-dn.net/?f=%5Csin%5E%7B2%7D%5Ctheta%20%3D%20%5Cfrac%7B1-%5Ccos%202%5Ccdot%20%5Ctheta%7D%7B2%7D%20%5C%5C%5Ccos%5E%7B2%7D%5Ctheta%20%3D%20%5Cfrac%7B1%2B%5Ccos%202%5Ccdot%20%5Ctheta%7D%7B2%7D)
Then, the equation is simplified by substituting its components:
![x = 1.40\cdot \left(\frac{1-\cos 2\cdot \theta}{2} \right)\cdot \left(\frac{1+\cos 2\cdot \theta}{2} \right)](https://tex.z-dn.net/?f=x%20%3D%201.40%5Ccdot%20%5Cleft%28%5Cfrac%7B1-%5Ccos%202%5Ccdot%20%5Ctheta%7D%7B2%7D%20%20%5Cright%29%5Ccdot%20%5Cleft%28%5Cfrac%7B1%2B%5Ccos%202%5Ccdot%20%5Ctheta%7D%7B2%7D%20%5Cright%29)
