Answer:
The measurement was off by 0.7%
Step-by-step explanation:
To find the relative error in the measurement, start by finding the difference.

Answer:
The first option
Step-by-step explanation:
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
Hope this helps :)
R=8+I
S=4R
R+I+S=112
R+R-8+4R=112
6R=120
R=20
So therefore, Ruby worked 20 hours, Svetlana worked 80 hours, and Isaac worked 12 hours.
