Step-by-step explanation:
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

What is the probability that a randomly chosen male voter is a registered Democrat? Round your answer to the nearest tenth of a percent.
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:
49%

A wall measures 2 meters 30 centimeters in width.
What is the width of the wall in millimeters?
A:0.0023 mm
B:0.23 mm
C:2.3 mm
D:2,300 mm
Answer:
The answer is D
Step-by-step explanation:
1 meter = 1,000 millimeters
1 centimeter = 10 millimeters
2 meters = 2,000 millimeters
30 centimeters = 300
2,000+30=2,300
Answer: D. 2,300
Step-by-step explanation:
There is 1000 millimeters in a meter which gets you 2000 plus the 30 centimeters. 30 centimeters is equal to 300 millimeters because for every centimeter its 10 millimeters. Add the 2000 to the 300 and get 2300 millimeters.

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. *
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.
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 hourtrain journey from Euston to Bimingham = 1 hour 10 minutesTrains 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 walkTotal 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

HELP HELP HELP What is the slope of the line that passes through the points (-3,-2) and (1,3)
Answer:
5/4
Step-by-step explanation:
Use rise over run, which is (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are points on the line
Plug in the points:
(y2 - y1) / (x2 - x1)
(3 + 2) / (1 + 3)
= 5/4
So, the slope is 5/4

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

Lara took a total of 10 pages of notes during 2 hours of class. After attending 9 hours of
class, how many total pages of notes will Lara have in her notebook? Solve using unit rates.
Fast please i need it asap thanks
Answer:
45 pages
Step-by-step explanation:
The unit rate is the number of pages divided by the unit of time
10 pages /2 hours
5 pages per hour
To find the total number of pages of notes take, multiply the unit rate by the total amount of time
We have 9 hours
5 pages per hour * 9 hours
45 pages
Answer:
take x to be the no. of pages for 9 hours
10 pages 2 hours
x pages 9 hours
Cross multiplication:
90 = 2x
x = 90/2
x = 45
Lara will cmplte 45 pages in 9 hours.
