Answer:
Step-by-step explanation:
To calculate a+1/a, we first need to calculate for a.
a = 7 - 4 * ![\sqrt[2]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B3%7D)
square root of 3 = 1.73
a = 7 - 4 * 1.73
a = 7 - 6.9
a = 0.1
0.1 + 1 / 0.1 = 0.1 + 10 = 10.1
Now, in case 4 wasn't being multiplied with the square root of 3, and instead, it was four root of 3, I am gonna do the calculations again:
a = 7 - ![\sqrt[4]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B3%7D)
a = 7 - 1.31
a = 5.69
5.69 + 1 / 5.69 = 5.69 + 0.17 = 5.86
Hope I Helped!
The answer is -6
So you need to drop the word sum on -6
UUUUhhhhhh....i cant really see it sorry.
Answer:
Therefore, the error is 52-50.27=1.73.
Step-by-step explanation:
We know that Sid used geometry software to draw a circle of a radius 4 units on a fgrid. He estimated the area of the circle by ciunting the squares that were mostly inside the circle and got an answer of 52 sq units.
We use the formula:

Therefore, the error is 52-50.27=1.73.
