Step-by-step explanation:
For every 1 hour across, the graph rises by 4 to 6 miles.
Therefore the constant of proportionality is around 4 to 6.
The best answer here is 4.5. (B)
Answer:
her degree of accuracy in measurement is 0.05 cm (Option D)
Step-by-step explanation:
The degree of accuracy in the measurement of the botanist depends on the instrument used.
For a length of 3.56 centimeters, it shows that the length of the tomato seedling was measured using meter rule or tape.
Meter rule is graduated in 1 mm or 0.1 cm. The estimated uncertainty in measurement using meter rule is half of its graduation i.e ( ¹/₂ of 0.1 cm = 0.05 cm).
If the botanist measured the length of tomato seedling as 3.56 centimeters, then her degree of accuracy in measurement is 3.56 cm ± 0.05 cm.
Therefore, her degree of accuracy in measurement is 0.05 cm (Option D)
Equation:
Time*speed= distance
1.7(time)*22.4(speed)=38.08meter(distance)
A rational number is a number that can be made by dividing two integers. An integer is a number that doesn't have a fraction part.
1. 2.4 - rational
2. 74 - rational
3. 17.3333333… - rational
4. π -irrational
5. there is no number
6. –18 - rational
7. there is no number
8. 87.125 - rational
9. –30 - rational
10. –8.3 -rational
11. 58.25 -rational
12. 121 -rational
13. 4.5 -rational
14. 3 7/10 -rational
As you can see, most numbers are rational. But, when you come across pi or when you have a decimal that goes on forever without repeating (like some square roots), it tends to be irrational.
