Two cells are viewed and measured under a microscope. The approximate diameter of each cell is listed.
Cell P: 5.0×10^−4 m
Cell Q: 3.0×10^−5 m
Which expression would you use to find the difference between the two diameters? (1 point)
(5.0×10^−4)(3.0×10^−5)
(3.0×10^−5)÷(5.0×10^−4)
(5.0×10^−4)÷(3.0×10^−5)
(3.0×10^−5)−(5.0×10^−4)
(5.0×10^−4)−(3.0×10^−5)
(3.0×10^−5)(5.0×10^−4)
(5.0×10^−4)−(3.0×10^−5)
Two cells are viewed and measured under a microscope. The approximate diameter of each cell is listed.
Cell P: 5.0×10^-4
Cell Q: 3.0×10^−5
What is the difference in the diameters of the two cells? (1 point)
0.05 m
0.047 m
0.00047 m
0.002 m
To find the difference in the diameters, we subtract the diameter of cell Q from the diameter of cell P:
(5.0×10^-4 m) - (3.0×10^-5 m) = (5.0 - 0.3) x 10^-4 = 4.7 x 10^-4 meters
Therefore, the difference in diameter between the two cells is 0.00047 m or 4.7 x 10^-4 m.
The closest option is:
0.00047 m
