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

A number is selected randomly from the integer from 10to30 what is the probability of picking a multiple of 4or5​
arlik [135]

Answer:

\frac{3}{7}

Step-by-step explanation:

Start by finding how many integers there are from 10-30...

30-10+1=20+1=21

Note we have to add 1 since it is inclusive.

Now, let's find how many multiples of 4 or 5 there are from 10-30...

4*3=12

4*4=16

4*5=20

4*6=24

4*7=28

5*2=10

5*3=15

5*4=20

5*5=25

5*6=30

5+5-1=9

Note we have to subtract 1 since 20 is counted twice.

The probability would be...

\frac{Multiples\ of\ four\ and\ five\ from\ 10-30}{Amount\ of\ integers\ between\ 10-30}=\frac{9}{21}=\frac{3}{7}

Find 10 onomatopoeia words and use them to write your OWN onomatopoeia poem,
blondinia [14]

Answer:

“Oh, the bells, bells, bells!

What a tale their terror tells

Of Despair!

How they clang, and clash, and roar!

What a horror they outpour

On the bosom of the palpitating air!

Yet the ear it fully knows,

By the twanging,

And the clanging,

How the danger ebbs and flows;

Yet the ear distinctly tells,

In the jangling,

And the wrangling.”

21. Angela until the same restaurant four times. Each time she ordered a salad and left at $ 5 tip. She spent a total of $ 54. W
Natalka [10]

So if Angela entered the same restaurant 4 times, we have 4 "instances" of her entering the restaurant.

Each instance, she ordered a salad. The price of this salad is unknown, so we'll say the price is "S".

Each instance, she payed a $5 tip.

So we have 4 instances of spending S, and 4 instances of spending 5.

We know this totals 54.

Knowing all of this information, we can write our equation like this:

4(S + 5) = 54

Divide

S + 5 = 13.50

Subtract

S = 8.50

The cost of salad is $8.50

How do you do this question?
raketka [301]

Answer:

The required relation is,

  \frac {dV}{dt} = c{\frac{dT}{dt}}

Step-by-step explanation:

We know that for a certain amount of dry gas when the pressure is kept constant it's volume V and temperature T is related by the function,

V = cT -----------------------(1) [where "c" is a constant]

So, in that case rate of change of volume(V) with respect to time (t),

             = \frac {dV}{dt}

will be equal to ,

               c{\frac{dT}{dt}}

where \frac {dT}{dt}  is equal to rate of change of temperature (T) with  respect to time (t) and c is the constant stated before.

So, the required relation is,

  \frac {dV}{dt} = c{\frac{dT}{dt}}
