Question

Four percent of Jennie's skin cells were burned when she escaped from a fire. If 3.7 x 10^10 of her skin cells were burned then, how man skin cells were not burned?

Answer 1

Answer:

355.2

Step-by-step explanation:

Given:

Four percent of Jennie's skin cells were burned

Total skin cells having Jennie = 3.7 x 10^10

                                                  = $3.7\times10\times10 = 370$

To find:

How man skin cells were not burned ?

Solution:

Total skin cells having Jennie = 370

Percent of Jennie's skin cells were burned = 4%

Skin cells burned  from a fire = $370 \ of 4\%$

                                                = $370\times\frac{4}{100} =\frac{1480}{100}$

                                                = $14.8$

Remaining skin cells which not burned = 370 - 14.8 = 355.2

Therefore,  355.2 skin cells were not burned.
