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.

Answer:
X=4
Step-by-step explanation:
We just have to see what equals 22 added with 6 and 16+6=22 and 16/4=4
Answer:
x=4
Step-by-step explanation:
First, we need to get rid of the integers:
4x = 22-6
Now, we solve that part:
4x = 16
If 4x is 16, then what is x? To solve this, we divide each side of the equation by 4:
x=4

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
A circular table top has a radius of 24 inches.
What is the area of the table top, to the nearest square inch? Use 3.14 for Pi.
75 in.2
151 in.2
1809 in.2
7235 in.2
Answer:
1809 in.2.
Step-by-step explanation:
So we know that the formula of a circle's area is r^2 * pi.
In this case, the radius is 24 inches. 24^2 = 576. They tell us to use 3.14 for pi.
576 * 3.14 = 1808.64.
The area is 1808.64, which rounds up to 1809 in.2.
Hope this helps!

Slope intercept form of y - 8 = -1/2(x+4)
Answer:
y = − 1 /2 x + 6
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
Step by step please and thank you
Answer:
x = -3
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
4x - 5 + 2x - 6 = 12x + 7
6x - 11 = 12x +7
6x - 12x = 7 + 11
-6x = 18
x = -3

Answer:
Step-by-step explanation:
the area of a parallelogram is the same as a rectangle, well, uses the same formula. therefore it uses base × height.
for this equation we need to do 7.1 × 11.4
7.1 × 11.4 = 80.94
if you need to round the number to a whole number, it will be 81 because the first decimal digit is the number 9, and any decimal number 5 or up rounds up to the next number :D
good luck :)

Answer:
is this median numbers or mean?
Step-by-step explanation:
Show whether each value in the set {2,3,4} is a solution of the equation x + 2 = 6.
PLEASE HURRY. THIS IS DUE IN 7 MINUTES
Answer:
4
Step-by-step explanation:
Plug in each given value into the expression to see if it is true.
Set given: {2 , 3 , 4}
Equation given: x + 2 = 6
First, plug in 2 for x. When x = 2:
x + 2 = 6
(2) + 2 = 6
4 ≠ 6.
Next, plug in 3 for x. When x = 3:
x + 2 = 6
(3) + 2 =6
5 ≠ 6.
Finally, plug in 4 for x. When x = 4:
x + 2 = 6
(4) + 2 = 6
6 = 6 (True).
In the given set, only 4 complete the equation.

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.

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.

(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
Karthik borrows 1200 from junaid for 2 years for 20% rate of interest how much karthik should play to compound annually
Answer:
1728
Step-by-step explanation:
1200 borrowed for 2 years at 20% compounded annually ;
Using the compound interest formula :
A = P(1 + r/n)^nt
P = 1200 = principal
Time, t = 2 years
Rate, r = 20% = 0.2
A = 1200(1 + 0.2)^2
A = 1200(1.2)^2
A = 1200 * 1.44
A = 1728
Final amount to be repayed = 1728
