Let the time taken by train be 't' hrs.

Then,

40t = 35t + 1560

40t = 35t + 35/4

t = 7/4 hrs

Therefore, Required length of the total journey d = s x t

= 40 x 7/4

= 70 kms.

Answer 1)  

1/3 x (54 x 150 + 60 x 300 + 36 x 450)

= 1/3 x 42300

= 14100.

Answer 2)

Required ratio of chairs = 64 x 450 + 56 x 50036 x 450 + 44 x 500

= 56800/38200

= 284/191.

Answer 3)

Required number of chairs =  35 x 12100 x 50000
= 3600.

A compound sentence is a sentence that has at least two independent clauses joined by a comma, semicolon or conjunction. An independent clause is a clause that has a subject and verb and forms a complete thought.

Here except option A) other two options dependent.

Hence, A) We can go see a movie, or we can get something to eat is a compound sentence.

In the question it is asked for 5% of 1500

5 x 1500/100 = 15 x 5 = 75.

Hence, 5% of 1,500 is equal to 75.

The state of California uses a mechanism known as NOTS.

NOTS stands for Negligent Operator Treatment System.

What is this:

It is a program that is known to rehabilitate chronic violators of the driving laws in California. It consists of a series of computer generated warning letters and sanctions against violators. It affects drivers with age 18 years old and above in California.

How it works:

The actions in this program are based on "negligent operator points" that is being recorded every time period. These are added continuously until it reaches a certain degree which it needs an administrative hearing. Points are being assigned depending on the degree of the offense. It would range from zero to three points.

In a chemical reaction, substances (elements or compounds) called reactants are changed into other substances (compounds or elements) called products. Hence, reactants are those which start the chemical reaction.

For example:

1. In the burning of natural gas, methane (CH4) and oxygen (O2) are the reactants in the chemical reaction. are the substances formed by a chemical reaction. In the burning of natural gas, carbon dioxide (CO2) and water (H2O) are the products formed by the reaction.

2. H2+O2 ----> H2O

Here H2 & O2 are called Reactants and H2O is called Product.

Use HTML tag <ol> element to define an ordered list.

Use the HTML type attribute to define the numbering type. Use the HTML <li> element to define a list item. Use the HTML <dl> element to define a description list.

Hence, as numbered list come under ordered list tag <ol> tag is used for numbered list.
