A high-speed train travels at a speed of 200km/h. If the train sets off from Station A at 12 24 and reaches station B at 14 12, find the distance between the two stations.
Given:
Speed to train = 200km/h
The train sets off from Station A at 12:24.
Reaches station B at 14:12.
To find:
The distance between both stations.
Solution:
We have,
Speed to train = 200km/h
Time taken by the train to cover the distance between station A and station B is the difference between 14:12 and 12:24.
Time = 1 hr 48 min
Time = 1.8 hours [ 1 hr = 60 minutes]
Let d be the distance between both stations.
We know that,
[tex]Speed=\dfrac{Distance}{Time}[/tex]
[tex]200=\dfrac{d}{1.8}[/tex]
[tex]200\times 1.8=d[/tex]
[tex]360=d[/tex]
Therefore, the distance between the two stations is 360 km.
What does it mean to isolate the variable?
А: Evaluate the coefficient.
B: Reverse the inequality sign.
С: Get zero by itself on one side of the inequality sign.
D: Get the variable by itself on one side of the inequality sign.
Answer: D
Step-by-step explanation: get the variable by itself on one side of the inequality sign.
Get the variable by itself on one side of the inequality sign. Option D
How to determine the meaningIsolating a variable in an equation or inequality refers to changing it so that it is on its own on one side of the equation or inequality sign.
In order to remove any additional terms or factors that are affecting the variable, this entails applying different operations to both sides of the equation or inequality, such as addition, subtraction, multiplication, or division.
The objective is to make the inequality or equation simpler so that the variable can be solved more easily.

(a) A company has 39 salespeople. A board member at the company asks for a list of the top 5
salespeople, ranked in order of effectiveness. How many such rankings are possible?
Answer:
69090840 possible rankings
Step-by-step explanation:
The number of possible ranking ordered in terms of effectiveness can be obtained using permutation
Number of salesperson = 39
Number of rank = 5
nPr = n! ÷ (n - r)!
nPr = 39P5
39P5 = 39! ÷ (39 - 5)!
39P5 = 39! ÷ 34!
39P5 = 39 * 38 * 37 * 36 * 35 = 69090840

You and your family go to dinner and you leave an 18% tip for the server. If the meal costs $52.50, how much should you leave for a tip?
Answer:
You should leave $9.45 for the tip!
Step-by-step explanation:
52.5 x 0.18 = 9.45
hope this helped! UwU
Answer:
You should leave a $9.45 tip.
Step-by-step explanation:
Here is a simple way to do this. Break it down into easy percentages.
$52.50 is a 100% tip.
$5.25 is a 10% tip.
$.525 is a 1% tip.
Multiply $.525 by 8 to get an 8% tip.
The answer to that will be $4.20.
Now add $4.20 and $5.25 to get an 18% tip.
Your answer is $9.45.

What is the missing value?
54
30%
100%
?
Answer:
the missing value is 18.
Step-by-step explanation:
First i converted the percentage to a fraction which was 30% was 3/10 or 0.3 or 3 and 100% was 1 so i took those numbers with 54, 1, 3, and Solve for an unknown value x with this fractions calculator. Find the missing fraction variable in the proportion using cross multiplication to calculate the unknown variable x. Solve the proportion between 2 fractions and calculate the missing fraction variable in equal's.
For the equation
543=x1
The cross product is
54×1=3×x
Solving for x
x=54×13
and reducing
x=18
Solution by Proportion
Since the equation is an equality
If
3 ÷ 1 = 3
Then it is true that
54 ÷ x = 3
Solving for x
x = 54 ÷ 3
x = 18

Answer:
-2 (filled in circle) to 7 (open circle)
Step-by-step explanation:
for the first equation x must be the equal to or smaller than 6. so -3(-2) equals 6 but anything less than -2, let's say -3(-3), will be BIGGER than six, so -2 including -2 which is a filled in circle.
solving it:
-3(x) [tex]\leq[/tex] 6
[tex]\frac{-3x}{-3} \leq \frac{6}{-3}[/tex]
[tex]x\leq -2[/tex]
for the second equation x must be smaller than 17. so first you take out + 3 by subtracting it, leaving the equation as 2x<14. 2(7)<14 is NOT true so anything bigger than 7 leaves it as true because 6.98934747483 can still make it true, so anything smaller than 7 which is 7 with a not filled in, or open, circle
solving it:
[tex]2x + 3 (- 3) < 17 (- 3)[/tex]
2x < 14
[tex]\frac{2x}{2} <\frac{14}{2}[/tex]
x < 7

Si elegimos un día de la semana al azar, ¿qué probabilidad hay de que sea fin de semana (ya sabemos que hay dos días…)?
Answer:
La probabilidad que hay de que sea fin de semana es [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
La Probabilidad es la mayor o menor posibilidad de que ocurra un determinado suceso. En otras palabras, la probabilidad establece una relación entre el número de sucesos favorables y el número total de sucesos posibles. Entonces, la probabilidad de un suceso cualquiera A se define como el cociente entre el número de casos favorables (número de casos en los que puede ocurrir o no el suceso A) y el número total de casos posibles. Esta se denomina Ley de Laplace.
[tex]P(A)=\frac{numero de casos favorables}{numero de casos posibles}[/tex]
En este caso:
número de casos favorables: 2 (cantidad de días del fin de semana)número de casos posibles: 7 (cantidad de días totales en la semana)Reemplazando:
P(A)= [tex]\frac{2}{7}[/tex]
La probabilidad que hay de que sea fin de semana es [tex]\frac{2}{7}[/tex]
