A man earns Rs 20 on first day and spends Rs 15 on next day. He again earns rs 20 on third day and spends Rs 15 on fourth day.If
finlep [7]

Answer:

It will take him 24 days to have Rs 60 in hand.

Step-by-step explanation:

A man earns Rs 20 on first day and spends Rs 15 on next day. He again earns rs 20 on third day and spends Rs 15 on fourth day. It means that in 2 days, the man saves Rs 5, in 4 days, he saves 5 + 5 = Rs 10. On the sixth day,he would be having 5+5+5 = Rs15 and on the eighth day, he would be having 5+5+5+5 = Rs 20

If he continues to save in this way, the number if days it will take him to save Rs 60 would be

(60×2)/5 = 24

For an Isosceles triangle of base b and congruent sides, x units long, what is the range of angle measures for the angle measure
olga2289 [7]

Answer:

the desired range is 0° < angle < 180°

Step-by-step explanation:

If 2x were just slightly less than b, then the angle opposite the base would be just less than 180 degrees.

The larger the value of x, the further the intersection of the two congruent sides is moved away from the base b.  The angle between these two congruent sides would approach but never equal zero.

Thus, the desired range is 0° < angle < 180°
