When lava is expelled from a volcano, it temperature may vary from 700 degrees Celsius to 1200 degrees Celsius. Write an absolut
ValentinkaMS [17]

Answer:

Ix - 950°C I ≤ 250°C

Step-by-step explanation:

We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.

And that this temperature is x.

This means that the minimum value of x is 700°C while maximum of x is 1200 °C

Let's find the average of the two temperature limits given:

x_avg = (700 + 1200)/2 =

x_avg = 1900/2

x_avg = 950 °C

Now let's find the distance between the average and either maximum or minimum.

d_avg = (1200 - 700)/2

d_avg = 500/2

d_avg = 250°C.

Now absolute value equation will be in the form of;

Ix - x_avgI ≤ d_avg

Thus;

Ix - 950°C I ≤ 250°C

How to divide fractions
Anna [14]

First leave the first fraction alone.

Then turn the division sign into a multiplication sign.

Flip the second fraction over ( find its reciprocal ).

Multiply the numerators of the two fractions together. This result will be the numerator ( the top part ) of your answer.

Multiply the denominators of the two fractions together. The result will be the denominator ( the bottom part ) of your answer.

Then simplify your fraction by reducing it to the simplest terms.
