Question:
Solve each calculation. Be sure to report your answer with the correct number of significant figures.
5.61000 dg × 1.1010 dg
12.0 m ÷ 3.1415 m
Answer:
1.
=
2. 
Step-by-step explanation:
1. 5.61000 dg × 1.1010 dg
We start by representing each digit using scientific notation


Then, Multiply both numbers

First, rearrange


From law of indices,
;
So, we have

Because 5.61000 is given in 3 significant figures and 1.1010 is given in 4 significant figures, we approximate the result to 4 significant figures
This gives
Hence,
=
2.
12.0 m ÷ 3.1415 m
Using proper notation
12.0 m ÷ 3.1415 m = 
We start by representing 3.1415 using scientific notation

By substitution;

Take
to the numerator

From law of indices,
= 10000

Multiply

Divide

Because 12.0 is given in 2 significant figures and 3.1415 is given in 5 significant figures, we approximate the result to 5 significant figures

Answer:
28
Step-by-step explanation:
6x + 7y - 5
x = 2
y= 3
6(2) + 7(3) - 5
12 + 21 - 5
33 - 5
