5. Two trains travel in the same direction on

Mathematics
1 answer:
Sedbober [7]1 year ago
6 0

If the speed of train A is 90 kilometers per hour and the speed of train B is 100 kilometers per hour then after 5 hours they will be in the same place.

Given that the speed of train A is 90 kilometers per hour and the speed of train B is 100 kilometers per hour.

We are required to find the time after which both the trains will be in same place.

Speed is basically the distance travelled in a particular time.

Speed=Distance/Time.

Because the difference between both the train A and train B is 10 kilometers per hour so train B will cover 50 kilometers in 5 hours.

They will be at same place after 5 hours.

Hence if the speed of train A is 90 kilometers per hour and the speed of train B is 100 kilometers per hour then after 5 hours they will be in the same place.

The price of a pair of pants is $29.95 and the sales tax is 5%.
Vika [28.1K]

Answer: $31.45

Step-by-step explanation:

Given : The price of a pair of pants is $29.95.

The sales tax is 5% = 0.05

Required formula :

Total cost = Price + sales tax percent × Price

Total cost= Price (1+Sales tax percent)

i.e. Total cost of the pair of pants= 29.95 (1+0.05) =29.95(1.05)=31.4475 ≈ 31.45

Hence, the total cost of the pair of pants = $31.45

One number is 18 more than another number. The sum of the numbers is 36. find the numbers
tatuchka [14]

We can use a system of equations in order to solve for both of the numbers. Let's start off by assigning variables to each number. The bigger number can be 'x', and the smaller number can be 'y'.

We can make two equations from the given:

x = 18 + y

("One number is 18 more than another number")

x + y = 36

("The sum of the numbers is 36")

If you look at the first equation, the variable 'x' already has a value (18 + y). We can input its value into the second equation in order to solve for y:

x + y = 36

(18 + y) + y = 36

18 + 2y = 36

2y = 18

y = 9

Input the value of 'y' into the first equation:

x = 18 + y

x = 18 + 9

x = 27

<u>One number is 27 and the other number number is 9.</u>

<u></u>

Let me know if you'd like me to explain anything I did here.
