Firstly, given this information there could be 25 labradors and poodles and only 4 boxers and 1 spaniel. However, assuming that there are only boxers and spaniels at the dog show the first thing to do is to divide 30 by 5 = 6 so the answer is, There are 6 spaniels.

1/4x -2 = -6 + 5/12x
3x - 24 = -72 +5x
3x -5x = -72 +24
-2x = -48
x = 24

water in a canal , 6m wide and 1.5m deep , flowing with a speed of 10km/h . How much area will it irrigate in 30 minutes , if 8
icang [17]

The area covered by the canal in 30 mins is 562500 sq m

Step-by-step explanation:

Step 1 :

Given,

The canal's width = 6 meter

The canal's Depth is given as 1.5 meter

Speed of the water flowing = 10 kilometer per hour  

We need to determine the area which will be irrigated in 30 mins

Step 2 :

In one hour the canal flows 10 kilometer , therefore in 30 minutes it covers 5 kilometer = 5 × 10^{(3)} meter

Hence the volume of the water irrigated per 30 minutes = 6 × 1.5 × 5 × 10^{(3)}

= 45 × 10^{(3)}   cubic meter

The standing water is 8 centimeter = 8 × 10^{(-2)}  meter

Hence the area covered in 30 min = Volume ÷ the height of the standing water

= (45 × 10^{(3)} )  ÷ 8 × 10^{(-2)}   meter

= 562500 square meter

Step 3 :

The area covered by the canal in 30 mins is 562500 square meter
