s344n2d4d5 [400]

Answer: There were 741 books in the library a year later.

Step-by-step explanation:

Given: Total books in library = 570

Number of books increased by 30%.

One year later, Number of books in the library = (Total books in library) + 30% x (Total books in library)

= 570 + (0.30) x (570)

= 570 (1+0.30)

= 570 (1.30)

= 741

Hence, there were 741 books in the library a year later.

Answer:

93.75 Kg

Step-by-step explanation:

Farmer spreads 25 kg fertilizer over an area of 4000 m square .

So, Over 1 m square , $\frac{25}{4000}$ kg of fertilizer will be needed

As we know , 1 hectare = 10,000 m square.

So, 1.5 hectare equals 15,000 m square.

So, for 15,000 m square , Fertilizer needed will be equal to $\frac{25}{4000}$ ×15,000 = 93.75 Kg

So, 93.75 Kg of fertilizer is needed for 1.5 ha of land.
