Answer:
Is the 4 divided by everything?
Step-by-step explanation:
Well by adding that up it would be 272.94
<h3>
Solution (a):</h3>
<em>~Let's change 9.9² to 10² since we have to estimate.~</em>
<u>We know that:</u>
- 10² = 100
- Given expression: 9.9² × 1.79
<u>Solving the expression:</u>
- 9.9² × 1.79
- => 10² × 1.79
- => 100 × 1.79
- => 179
The estimated value of 9.9² × 1.79 is 179.
<h3>Solution (b):</h3>
<em>~Let's change √97.5 to √100 and 1.96 to 2</em> <em>since we have to estimate.~</em>
<u>We know that:</u>
- √100 = 10
- Given expression: √97.5 ÷ 1.96
<u>Solving the expression:</u>
- √97.5 ÷ 1.96
- => √100 ÷ 2
- => 10 ÷ 2
- => 5
The estimated value of √97.5 ÷ 1.96 is 5.
Answer:
Step-by-step explanation:
The answer is Option A. Because the rate of change is that the tire loses 3 air pressure every hour, it is a constant, making it a linear relationship.
