The fastest train on Earth, the TGV from France can travel at faster speeds than most any other train. During a test, the train travel 800 miles in 2.5 hours. What is its speed?

Answer:

39

Step-by-step explanation:

sum of interior angles of a triangle is 180

180-(102+39)=x

180-141=x

39=x

Answer:

39

Step-by-step explanation:

it should all add up to 180

102 + 39 = 141

180 - 141 = 39

Answer:

C: $30/hr

Step-by-step explanation:

In order to find the rate per hour you must divide: 150 ÷ 5

Which will give you 30

Also if you took away the 0 in "150" then it would be like says "15 ÷ 5" which is 3 but then you have to add the zero back making it 30

Therefore your overall answer is going to be C, $30/hr

Answer:

680kg

Step-by-step explanation:

The average weight of ten bulls is 500kg and the standard deviation of the weight is 30kg. What would be the weight of a bull that is 6 standard deviations above the mean weight

The formula to solve for the weight that is 6 standard deviation above the mean weight =

μ + 6σ = w

Where

μ = Mean weight = 500kg

σ = Standard deviation = 30kg

Hence:

w = 500kg + 6(30kg)

w = 500kg + 180kg

w = 680kg

Therefore, the weight of a bull that is 6 standard deviations above the mean weight is 680 kg

Using the normal distribution, it is found that the weight of a bull that is 6 standard deviations above the mean weight is of 680 kg.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are, respectively, of [tex]\mu = 500[/tex] and of [tex]\sigma = 30[/tex].

The weight of a bull that is 6 standard deviations above the mean weight is X when Z = 6, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]6 = \frac{X - 500}{30}[/tex]

[tex]X - 500 = 6 \times 30[/tex]

[tex]X = 680[/tex]

The weight of a bull that is 6 standard deviations above the mean weight is of 680 kg.

Answer:

The answer should be [tex]9*10^{16}[/tex]

Step-by-step explanation:

Answer:

angle ADB = 41 degrees

angle ABD = 90 degrees

angle AFE = 70 degrees

angle ACE = 31 degrees

Step-by-step explanation:

angle ADB = 41 degrees because minor arc AB = 82 degrees and it's inscribed angle is 1/2 of it's arc.

angle ABD = 90 degrees because arc AED = 180 degrees and inscribed angles are equal to 1/2 of the arc.

arc ABD = 180

arc ABE = arc ABD + 70 degrees = 250 degrees

minor arc AE = 360 degrees-250 degrees = 110 degrees

angle AFE = 1/2 (250-110) = 70 degrees

angle ACE = 1/2(110-48) = 31 degrees

the answer is 2 or 2/1 hope this helps

Answer:

In fraction form, the slope is 2/1.

Or, the slope is just 2.

Step-by-step explanation:

Using the equation:

m =  

y2 - y1  /

x2 - x1

Plug in the x and y points and solve.

note: m = slope in slope intercept form, y - mx + b

y2 = 14     y1 = 18

x2 = -16     x1 = -14

14 - 18 / -16 -(-14)

-4 / -2

Simplified: -2 / -1

In fraction form, the slope is -2 / -1, or 2/1 because either way works.

Or, the slope is just 2.

Answer:

8n+16.2=1.6

n=-1.825

Step-by-step explanation: Subtract 16.2 from both sides 8n+16.2-16.2=1.6-16.2

Simplify 8n=-14.6/8

n=-1.825

Answer:

-1.825

Step-by-step explanation:

8n  +  16.2  =  1.6

(step1)      

8n  +  16.2  =  1.6

        - 16.2     -16.2

8n      =      -14.6

(step2)

8n =  -14.6

----    ------

 8      8

(step3)

-1.825

1. subtract 16.2 from both sides, you have to get rid of the number that is being add/subtracted to get the n and result alone

2. divide by the number next to the variable since you have to get the variable alone in order to find out what it is. you divide because you have to do the opposite of what the variable IS doing.

3. get the result lol

The minimum average score Ethan can earn on his fifth and final test is option (D) 60% is the correct answer.

An average of a list of data is the expression of the central value(mean) of a set of data. Average is calculated by adding quantities together and dividing the total by the number of quantities.

For the given situation,

The scores for 4 exams are 68%,72%, 85%, and 90%.

Let the score for the fifth test be x.

Formula for the average,

[tex]A = \frac{Sum of individual scores}{Total number of tests}[/tex]

⇒ [tex]75=\frac{68+72+85+90+x}{5}[/tex]

⇒ [tex]375=315+x[/tex]

⇒ [tex]x=60[/tex]

Hence we can conclude that the minimum average score Ethan can earn on his fifth and final test is option (D) 60% is the correct answer.

Answer:

75

Step-by-step explanation:

You will set the equation up as part/whole = percent/100 and when you replace it with your numbers you get 60/x = 80/100 now you cross multiply and do 60*100 = 80 * x and you get 6,000 = 80x now you divide both sides by 80 then you get 75 was the original price

The option C. Driver's License is not necessary to book a flight.

Driver's License is an official document given to a person who is permitted to drive vehicle on the road.

This is usually given after certain tests including Physical driving and other general knowledge of driving.

Now, when we book a flight, credit card can be used to book a flight, but not necessary.

But there is a chance than you can use the credit card.

Arrival city is necessary when you book a flight because then only other procedures will follow.

Similarly, date of travel is also required in order to book the flight on a particular day.

So the least necessary document is Driver's License.

Hence Driver's License is not necessary to book a flight.

Approximate difference between 1 mile and 2 km in meters = 390.66meters

Step-by-step explanation:

I mile =1609.34meters

also 1000m = 1km

therefore 2km = 2 x 1000= 2000m

Approximate difference = 2000m - 1609.34m

=390.66 meters.

 Approximate difference between 1 mile and 2 km in meters = 390.66meters
