A newborn baby has about 26,000,000,000 cells. An adult has about 4.94 x 10^*13 cells. How many times as many cells does an adult have than a newborn? Enter your answer in scientific notation.
An adult has about =
times more cells than a newbom baby.

I'm feeling alone and bored... innocent boy..

New born = 2.6 × 10¹⁰ cells.

Adult         = 4.94 × 10¹³ cells.

How many times more = adult cells ÷ newborn cells

                                      = 4.94 × 10¹³ cells ÷ 2.6 × 10¹⁰ cells

                                      =  1.9 × 10³ cells

the answer

b. they are parallel and will never intersect.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
