Step-by-step explanation:
Answer: the lower limit is 1.555g and the upper limit is 1.564g
Step-by-step explanation:
a mg is:
1mg = 0.001g
Then we need to look at the third digit after the decimal point.
Then the weight 1.56g is rounded around this.
Remember that if the third digit after the decimal point is 5 or bigger, then we round up.
if the third digit is smaller than 5, then we round down.
Now, the maximum possible value of this weight is when the third digit is equal to 4 (4 mg) where because it is smaller than 5, we round it down to 1.56g
Then the maximum is 1.564g
And the minimum value is when we have:
w = 1.555g
Because the third digit is a 5, we round it up to 1.56g.
So the lower limit is 1.555g and the upper limit is 1.564g

Answer:
A
Step-by-step explanation:
The diameter is 2πr or 4032π in this. The arc from B to C counterclockwise is 130° out of 360°. 130/360 multiplied by 4032 is 1456
12.74 rounds up to 13; 5.45 rounds down to 5. Recatangles gave 4 sides, two sides are thto same length as each other, and the other two sides are the same length as each other (which is a poor way to explain it). What that means in the context of this question is that there are two sides with length 13 and two sides length 5. So, added together 13+13+5+5 would be th total perimeter. As an expression, 2(13)+2(5)=26+10=36. The perimeter is approximately 36 meters.
