Answers
Answer:
1 . Therefore the product of two rational numbers is always a rational number.
2 .5t – 3 = 3t – 5 is a linear equation having a single variable in it. Therefore, this equation has only one solution. Therefore, we can write: Value of 't' is −1 in this case
3 . a is answer
4 . Regular polygon - A polygon having all sides of equal length and the interior angles of equal measure is known as a regular polygon i.e. a regular polygon is both 'equiangular' and 'equilateral'.
5 . 2 is the smallest number by which 98 should be divided so that the quotient may be a perfect square.
6 . 8 The value of the cube root of 512 is 8.
7 . cube of 300 ends with 300 = 27000000 so answer is 6
8 . 1 rupees= 100 paise
so , 30:200=3:20
9 . Data available in an unorganised form are called raw data. The number of times a particular observation occurs in a given data is called its frequency.
10 . The pictorial representation of a grouped data, in the form of horizontal or vertical rectangular bars, where the lengths of the bars are equal to the measure of data, are known as bar graphs or bar charts.
