an equilateral triangle has a square root height if 3 so I'm guessing if you multiply square root of 3 times 8
The best estimate of the lateral area of the cube with edges that are 2.1 inches long is 4.2
The opposite of 12.1 is 12.2
That would be 6 just put the the whole number over one and keep flip change
Answer:
The error interval for x is:
[3.65,3.74]
Step-by-step explanation:
The number after rounding off is obtained as:
3.7
We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:
3.65 3.66 3.67 3.68 3.69 3.70 3.71 3.72 3.73 3.74
( Because if we have to round off a number present in decimals to n place then if there is a number greater than or equal to 5 at n+1 place then it will result to the one higher digit at nth place on rounding off and won't change the digit if it less than 5 )
Hence, the error interval is:
[3.65,3.74]
