Answer: skin cells were not burned.
Step-by-step explanation:
<h3><u> The complete exercise is: Two percent of Sennie's skin cells were burned when she escaped from a fire. IfLet be "x" the number of Sennie's skin cells that were not burned when she escaped from the fire.
According the the data given in the exercise, you know that 2% represents of Sennie's skin cells that were burned. This means that the percent of her skin cells that were not burned is:
With this information you can write the following proportion:
Solving for "x", you get:
To express the result in Scientific notation, the decimal point must be after the first digit; then you must move the decimal point two places to the left:
ΔABC is a 45 - 45 - 90 triangle. The pattern of its sides is as follows:
Each leg = 1 unit (and both legs are that way, since the triangle is isosceles - so two sides are the same)
Hypotenuse = √2 units.
So if we know either leg, we multiply by √2 to get the hypotenuse. In reverse, we divide by √2 if we know the hypotenuse to get the measurement of a leg.
Our problem tells us that the hypotenuse AC is 10 units. We divide 10 by √2 to get the measurement of leg AB. Since it's a 45 -45 - 90 triangle, AB = BC.
to rationalize the radical
Thus, each leg is 5\sqrt{2} [/tex].
