If segment DF is an angle bisector, solve for x

Mathematics
1 answer:
klasskru [66]3 years ago
8 0

Answer:

x = 19

Step-by-step explanation:

Since DF is an angle bisector then it divides the opposite sides into segments that are proportional to the other 2 sides, that is

\frac{DE}{DG} = \frac{EF}{GF} , substitute values

\frac{25}{22.5} = \frac{x-9}{9} ( cross- multiply )

22.5(x - 9) = 225 ( divide both sides by 22.5 )

x - 9 = 10 ( add 9 to both sides )

x = 19

valkas [14]

Answer:

800 bacteria

Step-by-step explanation:

Over here, we have exponential growth.

So we have 50 bacteria

Every 30 minutes, it doubles in size

In 120 minutes, there are four 30 minutes.

So you do 50 * 2 * 2 * 2 * 2

Do that out and you get 800

JulijaS [17]

The measure of center that would best describe a typical value of the data set is a mean since the values are close.

<h3>What is a measure of center?</h3>

It should be noted that the measure of center include the mean, median, mode, and the mid-range.

In this case, when there is a close distribution of different numbers, he beta measurement will be the mean.

Therefore, the mean of the numbers will be:

= (20 + 21 + 21 + 25 + 20 + 23 + 27 + 23 + 24 + 25 + 26 + 24 + 23 + 22 + 24)/15

= 348/15

= 23.2
