Answer:
6.93
Step-by-step explanation:
√48 = √16 × √3
√48 = 4 × √3
√48 = 4 × 1.7321
√48 = 6.9284
Rounding up to 2 decimal places;
√48 = 6.93.
Note: In Mathematics, to round a number to 2 decimal places simply means to round up to the nearest hundredths.
1 decimal place = tenths.
2 decimal places = hundredths.
3 decimal places = thousandths.
Answer: Required expression: ![\dfrac{[ (86) + 0.18 \times(86 ) + 0.06 \times (86 )]}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5B%20%2886%29%20%2B%200.18%20%5Ctimes%2886%20%29%20%2B%200.06%20%5Ctimes%20%2886%20%29%5D%7D%7B4%7D)
Each person need to pay =$ 26.66
Step-by-step explanation:
Given: Bill amount = $86
Tip percent = 18%
Sales tax = 6%
Now, total bill = (Bill amount ) + 18% of (Bill amount ) + 6% of (Bill amount )
= $[ (86) + 18% of (86 ) + 6% of (86 )]
= $[ (86) + 0.18 x(86 ) + 0.06 x (86 )]
Total persons = 3+1 = 4
Each person need to pay= 
![=\dfrac{[ (86) + 0.18 \times(86 ) + 0.06 \times (86 )]}{4}\\\\=\dfrac{[ (86) (1+ 0.18 +0.06 )]}{4}\\\\=\dfrac{86(1.24)}{4}=\dfrac{106.64}{4}=26.66](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5B%20%2886%29%20%2B%200.18%20%5Ctimes%2886%20%29%20%2B%200.06%20%5Ctimes%20%2886%20%29%5D%7D%7B4%7D%5C%5C%5C%5C%3D%5Cdfrac%7B%5B%20%2886%29%20%281%2B%200.18%20%20%2B0.06%20%29%5D%7D%7B4%7D%5C%5C%5C%5C%3D%5Cdfrac%7B86%281.24%29%7D%7B4%7D%3D%5Cdfrac%7B106.64%7D%7B4%7D%3D26.66)
So, each person need to pay =$ 26.66
If there are 27 posts, then there are (n - 1) total spaces between the posts . . . 27 - 1 = 26 total spaces (since there has to be a post at each end of the line)
Here's an example of 7 posts equally spaced . . . so you can see there are one less spaces between posts than there are posts (i.e. 6 total spaces between 7 posts) . . .
[] . . . [] . . . [] . . . [] . . . [] . . . [] . . . []
27 posts = 27*(10cm) = 270 cm = 2.7m
26 spaces = 26*(30m) = 780 m
<u><em>Length of Fence = L = 780m + 2.7m = 782.7m</em></u>
still need help Orr? you got the answer already
I think it’s C but I don’t know
