This equation can be solved any of several ways. One that doesn't require much thought is using the quadratic formula.

For ax² +bx +c = 0, the solutions are ...

  [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

In the given equation, a=2, b=11, c=5, so this becomes ...

  [tex]x=\dfrac{-11\pm\sqrt{11^2-4\cdot2\cdot5}}{2\cdot2}=\dfrac{-11\pm\sqrt{81}}{4}\\\\x=\dfrac{-11\pm9}{4}=\left\{-\dfrac{20}{4},-\dfrac{2}{4}\right\}=\{-5,-\frac{1}{2}\}[/tex]

The solutions are ...

  C. x = -5

  D. x = -1/2

My personal favorite is using a graphing calculator. The solutions are the x-intercepts of the expression on the left. That is, where its value is zero, as the equation says.

8. In a triangle, the three angles are: 60, 11x and 13x degrees. Find the value
of x and plug it in to find the measure of the other two angles. Then classify
the triangle BASED ON ITS ANGLES. *

Answers

Answer:

x=5

Step-by-step explanation:

60+11x+13x =180° (sum of angles in a triangle )

60+24x=180

24x=180-60

24x=120

x=120/24

x=5

Therefore the angles are 60, 55, 65

Which shows that it is a scaleness triangle and an acute angle

Annabelle lives at Bermondsey in London. She has to speak at a conference inBirmingham at 10.30am.

It will take her an hour from her home to get to Euston Rail
Station, from where she will get a train to Birmingham.

The train journey from Euston
to Bimingham is an hour and 10 minutes.

Trains to Birmingham run at the following times: 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.

The meeting venue in Birmingham is a 5-minute walk from the station.

What is the latest time that Annabelle can leave home, if she is to make it on time for
the meeting in Birmingham

Show your work.

Please HELP!!! DUE TODAY!!
Thank you so much.

Answers

Answer:

7:45

Step-by-step explanation:

work backwards from 10:30!

u need 5 min to walk from meeting place to station, therefore u need to done riding the train by 10:25.

then u know that the train is an hour and 30 min, therefore u have to ride the train before or at 8:55 (10:25 minus an hour and a half)

the latest time for the train to leave is 45 min past the hour. therefore you will ride the 8:45 train.

since we already know that we are riding the 8:45 train by latest, you have to leave an hour early to get to the station. so you need to leave home by 7:45.

hope i was helpful !

The latest time that Annabelle can leave home is the she leaves home and she won't be late for her meeting

Time of meeting = 10.30am

Time she will spend before getting to meeting:

home to get to Euston Rail Station = 1 hour

train journey from Euston to Bimingham = 1 hour 10 minutes

Trains to Birmingham = 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.

The latest time is 45 minutes

Walk from the meeting venue in Birmingham from the station = 5 minute walk

Total time = 1 hour + 1 hour 10 minutes + 45 minutes + 5 minutes

= 3 hours

Counting 3 hours backward from 10:30 am = 7:30 am

Therefore, the latest time Annabelle can leave home is 7:30 am

Answer:

A. The triangles are similar because the ratios of the corresponding sides are the same

Step-by-step explanation:

Both ∆sloom similar in shape. Let's find out if they are actually similar.

∆TUV and ∆QRS are similar if the ratio of their corresponding sides are the same all through.

Thus:

TU = 70, QR = 25, UV = 84, RS = 30, TV = 42, QS = 15

If both ∆s are similar, then, TU/QR = UV/RS = TV/QS

TU/QR = 70/25 = 2.8

UV/RS = 84/30 = 2.8

TV/RS = 42/15 = 2.8.

Ratio of corresponding sides is the same, therefore, both triangles are similar.

Therefore, the following statement is true:

What is the probability that a randomly chosen male voter is a registered Democrat? Round your answer to the nearest tenth of a percent.

Answers

Answer:

49%

Step-by-step explanation:

Well, you would just divide the "male democrat" category and the "male total" category and then move the decimal over 2 spaces, because you need to multiply by 100 to turn your answer into a percent, so:

[tex]\frac{600}{1222}=0.49[/tex]

Then once you multiply by 100, or move the decimal to the left 2 spaces, it becomes:

Answers

Answer:

10 pages                      2 hours

x pages                         9 hours

Cross multiplication:

90 = 2x

x = 90/2

x = 45
