The second one is the right answer
The scale is likely to show the mass is either 270.9g or 245.1g
Step-by-step explanation:
Actual mass = 258g
Percent error = 5% = ±0.05
Mass shown by scale = Actual mass*percent error

Therefore,
Mass shown by scale = 258+12.9 , Mass shown by scale = 258-12.9
Mass shown by scale = 270.9g , Mass shown by scale = 245.1g
The scale is likely to show the mass is either 270.9g or 245.1g

Answer:
16+w
Step-by-step explanation:
The problem to solve is:
6+4+(w+2)+4
6+4 evaluates to 10
w+2 evaluates to w+2
10 + 2 = 12
The answer is 12+w
6+4+(w+2) evaluates to 12+w
12 + 4 = 16
The answer is 16+w
6+4+(w+2)+4 evaluates to 16+w
The final answer is
16+w
Answer:
2/3 or 0.66 repeated
Step-by-step explanation:
Since 2022 is only divisible by 1,2,4, and 5, the probability of getting a number that is a divisor of 2020 is 4/6, simplified to 2/3 or %0.66.
Should be no solution, cant divide a number by a fraction
