gizmo_the_mogwai [7]
A square will have the same length and width and area= length times width. its set up in a 4x4 square because there are 16 squares total; 4 across and 4 down. if the sides are 4 miles each then one whole side will be 16 miles. so the equation is 16 times 16 which equals 256. so the answer is 256 square miles.

Two percent of Jennies skin cells were burned when she escaped from a fire. If 
andreev551 [17]

1.813*10^{12} cells of Jennies skin were not burned.

Step-by-step explanation:

Given,

Burned skin cells = 3.7*10^{10}

This represents 2% of total skin cells.

Let,

x represents the total number of skin cells.

2% of x = 3.7*10^{10}

\frac{2}{100}x=3.7*10^{10}\\\\0.02x=3.7*10^{10}

Dividing both sides by 0.02

\frac{0.02x}{0.02}=\frac{3.7*10^{10}}{0.02}\\\\x=1.85*10^{12}

Number of not burned cells = Total - burned

Number of not burned cells = 1.85*10^{12}-3.7*10^{10}

Number of not burned cells = 1.813*10^{12}

1.813*10^{12} cells of Jennies skin were not burned.
