There are 98.4252 inches in 2.50m.
Unit Conversion is defined as a process that involves multiplication and division by a numerical factor or a particular conversion factor.
For Example .Convert 2m into cm.
As we know that 1m=100cm
multiplying both sides by 2 we get
2m = 200 cm.
According to the question
It is given that 2.54 cm = 1 inch
( as 100cm = 1m)
we need 2.50 m So we multiply both sides by 2.50
Therefore , there are 98.4252 inches in 2.50m.

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:
Step-by-step explanation:
So we have the inequality:
This means that our solution is all numbers <em>less than or equal to </em>-4. Therefore, in interval notation, this is:
This represents all the numbers from negative infinity up until -4. This is equivalent to the inequality.
