What is the equation of the line which intercepts x-axis and y-axis at 3/4 and 2/3 respectively?

Accepted Answer

Use the intercept form of a line, x/a + y/b = 1, where a = 3/4 and b = 2/3. Substitute values to get x/(3/4) + y/(2/3) = 1, which simplifies to 4x/3 + 3y/2 = 1. Multiply by 6 to clear denominators: 8x + 9y = 6.

Accepted Answer

Find the LCM of 15 and 35, which is 105. Divide the greatest four-digit number (9999) by 105. Subtract the remainder (99) from 9999 to get 9900. Then add 75 (105-30) to get 9975.

Question 5

The total surface area of a hemisphere is 462 sq cm, what is its curved surface area? (Take π = 22/7)

Accepted Answer

Total surface area of hemisphere = 3πr². Given 3πr² = 462, so πr² = 154. Curved surface area = 2πr² = 2 * 154 = 308 sq cm.

Question 6

In the following question, a sentence has been given in Direct/Indirect speech. Out of the four alternatives suggested, select the one which best express the same sentence in Indirect/Direct speech."Please don't hit me" Rita said to the attacker.

The direct speech is an imperative negative. 'Please' indicates a request or begging. The correct indirect form uses 'begged' and 'not to' before the verb, making option 1 correct.

Question 7

Improve the bracketed part of the sentence. Human beings are social animals, (who are living in communities), regulated by social norms and laws.

The phrase 'who are living' is redundant. The present participle 'living' alone effectively conveys the same meaning while making the sentence more concise and grammatically sound.

The value of tan3A is a standard trigonometric identity. It is given by the formula (3tanA - tan³A) / (1 - 3tan²A).

Question 11

Which of the following points lies on the line 5x + 4y = 2?

Accepted Answer

Substitute the coordinates of each option into the equation 5x + 4y = 2. Only option 3, (-2,3), satisfies the equation: 5(-2) + 4(3) = -10 + 12 = 2.
