Marissa is reading over her blood work results from her doctor. According to the report, there are about 3.7 × 105 platelets and about 9,300 white blood cells in a microliter of blood.
What is the total number of platelets and white blood cells in a microliter of blood?
A.
4.63 × 105
B.
3.8 × 105
C.
4.63 × 104
D.
3.8 × 104
A. 4.63 × 105
are you sure
Apologies for the confusion. Let's calculate the total number of platelets and white blood cells in a microliter of blood.
Platelets: 3.7 × 10^5
White blood cells: 9,300
Total = 3.7 × 10^5 + 9,300
Total = 370,000 + 9,300
Total = 379,300
So, the correct answer is B. 3.8 × 10^5. Thank you for pointing that out!
