Answer 1

Answer:

47) 3

Explanation:

average of 1+2+3+4+5/total no of element is 5

= 1+2+3+4+5/5

=15/5

=3

Answer 2

Answer:

45.5 is equal to 46.

A right angle has 90°.

Average of 1+2+3+4+5 is 15.

The area of a rectangle is L x H.

The simple interest on 10000 in 2 years at the rate of 5% per annum is 50.

The expression of algebraic formula ( x - y

) is (x - y) (x - y).
