Two percent of Jennie’s skin cells were burned when she escaped from a fire. If 3.7×10^10 of her skin cells were burned then, ho

gulaghasi [49]

$1813\times10^9$ cells were not burnt when Jennie escaped from the fire.

<u>Solution:</u>

Given:

2% of skin cells were burnt i.e, $3.7\times10^{10}$ of skin cells were burnt.

To find:

Number of skin cells that were not burnt

We can write $3.7\times10^{10} \text{ as } 37\times10^{9}$

Therefore, by equating the values we get,

2% of the cell is $37\times10^9$

1% of the cell is $\frac{37\times10^9}{3}=18.5\times10^9$

As, 1% of the cell is $18.5\times10^9$

98% of the cell will be $98\times18.5\times10^9=1813\times10^9$

$\therefore \text{ skin cells that are not burnt is } 1813\times10^9$

The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function?

gogolik [260]

Answer: If you plot a point in the y-axis at -6, you can plot two more points by using the slope "rise over run" Then draw a line connecting the points.

The coordinate of the y intercept is (0.-6) To find the first x values of the first 2 coordinates, add 1 then 2 to 0. To find the y values, add 2 then 4 to the -6

Step-by-step explanation:

From -6 go up 2 over 1 and plot at (1, -4 ) then up 2 over 1 again to (2, -2)

The x- intercept will be at (3,0)
