Platelets and red blood cells are components of the blood. A typical platelet and red blood cell have diameters of approximately 2.33×10−6 m and 0.0000075 m, respectively. Which blood component has a bigger diameter, and approximately by how much?
To compare the diameters of the blood components, we need to find the difference between the diameters of the platelets and red blood cells.
The diameter of a platelet is approximately 2.33×10^(-6) m.
The diameter of a red blood cell is approximately 0.0000075 m.
To find the difference, we subtract the diameter of the platelet from the diameter of the red blood cell:
Difference = Diameter of red blood cell - Diameter of platelet
Difference = 0.0000075 m - 2.33×10^(-6) m
Using scientific notation for easy comparison, we have:
Difference = 7.5×10^(-6) m - 2.33×10^(-6) m
Difference = 5.17×10^(-6) m
Therefore, the red blood cell has a bigger diameter than the platelet by approximately 5.17×10^(-6) m.
China and India are the most populous countries in the world. China’s population is approximately 1.45×109 , while India’s population is approximately 1,400,000,000. How many more people live in China than in India?
To find out how many more people live in China than in India, we subtract the population of India from the population of China.
Population of China = 1.45×10^9
Population of India = 1,400,000,000
Difference = Population of China - Population of India
Difference = 1.45×10^9 - 1,400,000,000
Using scientific notation for easy comparison, we can convert the population of India to scientific notation:
Population of India = 1.4×10^9
Now we can subtract the population of India from the population of China:
Difference = 1.45×10^9 - 1.4×10^9
Difference = 0.05×10^9
To simplify, we can convert 0.05×10^9 to standard form:
Difference = 0.05×10^9
Difference = 5×10^7
Therefore, China has approximately 50,000,000 (or 50 million) more people than India.
To determine which blood component has a bigger diameter and by how much, we can compare the diameters of the platelet and red blood cell.
Given:
Diameter of a platelet = 2.33 × 10^(-6) m
Diameter of a red blood cell = 0.0000075 m
To compare the diameters, we subtract the smaller diameter from the larger diameter:
0.0000075 m - 2.33 × 10^(-6) m = 0.000005168 m
Therefore, the red blood cell is bigger in diameter than the platelet by approximately 0.000005168 m.
To determine which blood component has a larger diameter and approximately by how much, we'll compare the diameters of platelets and red blood cells.
Given:
Diameter of a platelet = 2.33×10−6 m
Diameter of a red blood cell = 0.0000075 m
To find the difference in diameter, we can subtract the diameter of the smaller blood component from the diameter of the larger one.
Let's start by comparing the diameters:
Platelet diameter = 2.33×10−6 m
Red blood cell diameter = 0.0000075 m
Since the red blood cell diameter is expressed in millimeters (0.0075 m), let's convert the diameter to meters to have a consistent unit for comparison:
Red blood cell diameter = 0.0075 m
Now we can compare the two diameters: 2.33×10−6 m and 0.0075 m.
The red blood cell has a larger diameter because 0.0075 m > 2.33×10−6 m.
To find the approximate difference in diameter, we can subtract the smaller diameter (platelet) from the larger diameter (red blood cell):
Approximate difference in diameter = 0.0075 m - 2.33×10−6 m
To simplify the calculation, we'll subtract the numbers using scientific notation since the difference in magnitudes is significant.
0.0075 m - 2.33×10−6 m = 0.0074997667 m
So, the approximate difference in diameter between the red blood cell and platelet is 0.0074997667 meters or 7.4997667 mm.
