Answer:
2, 3
1.01, 1
Percentage uncertainty
Step-by-step explanation:
a) The significant figures in the number 99 is 2
The significant figures in the number 100 is 3
b) Uncertainty in each of the numbers for both the numbers is 1
Percentage uncertainty
99
Percentage uncertainty = 1.01
100
Percentage uncertainty = 1
c) Percentage uncertainty is a better way to express the numbers as the significant figures do not show the actual value of the numbers.
For this case, what we must do is find the scale factor.
We have then that the scale factor is given by:
Where,
L1: side length of polygon ABCD
L2: side length of polygon PQRS
Note: both sides belong to the same side of each polygon
Substituting the values we have:
Rewriting we have:
Answer:
The scale factor of dilation is given by:
Answer:

Step-by-step explanation:
Answer:
81 m/s
Step-by-step explanation:
If the box is sliding at 27 m per second, and it's been sliding for 3 seconds, then you should multiply 3 × 27 and your answer would be 81 m/s
