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.

In ΔEFG, the measure of ∠G=90°, EF = 38 feet, and FG = 30 feet. Find the measure of ∠F to the nearest degree.
Mamont248 [21]

Answer:

∠F = 42° to the nearest degree

Step-by-step explanation:

In this question, we are asked to calculate the value of the angle.

Kindly note that since one of the angles we are dealing with in the triangle is 90°, this means that the triangle is a right-angled triangle

Please check attachment for the diagrammatic representation of the triangle

From the diagram, we can identify that the EF is the hypotenuse and the length FG is the adjacent. Thus , the appropriate trigonometric identity to use is the cosine

mathematically;

Cosine of an angle = length of adjacent/length of hypotenuse

Cos F = \frac{30}{38}\\Cos F =  0.7895\\F = Cos^{-1} 0.7895\\

F = 42.07

∠F = 42° to the nearest degree
