Step 1:
Find how many microliters of blood there are in a 140lb person.
=140 * (2.7*10^4)
=140*(2.7*10*10*10*10)
=140*27,000
=3,780,000 # of microliters of blood in a 140lb person
Step 2:
Find how many white blood cells in a 140lb person
=3,780,000* (7*10^4)
=3,780,000*(7*10*10*10*10)
=3,780,000*(70,000)
=264,600,000,000 # of white blood cells in a 140lb person
(or 2.646 * 10^11 using scientific notation)
Hope this helps! :)
Ricky jogged 6 miles on tuesday and 6 miles on friday
<em><u>Solution:</u></em>
Given that,
Rick jogged the same distance on tuesday and friday
Let "x" be the distance jooged on each tuesday and friday
He also jogged for 8 miles on sunday
Total of 20 miles for the week
Therefore, we frame a equation as,
total distance jogged = miles jogged on tuesday + miles jogged on friday + miles jogged on sunday
20 = x + x + 8
20 = 2x + 8
2x = 20 - 8
2x = 12
x = 6
Thus Ricky jogged 6 miles on tuesday and 6 miles on friday

Multiplying by 2/2 is like multiplying by 1, so it doesn't affect the value.
To add fractions with the same denominator just add the numerator, the denominator stays the same.
