Airida [17]
If the required rate is gallons per minute, then its obvious from the question, that the rate of filling the pool is 10 gallons per minute, and its obviously a constant number. 
But for the rate to be in gallons per hour, then 
1 minute corresponds to 10 gallons
so 
1 hour corresponds to 10x60 = 600 gallons
hence
rate (gallons per hour) = 120,000/600 =  200 gallons per hour. 
which is again a constant number.

Elan Coil [88]

The window that has the shape of a kite has the area of the glass as 648 centimetre squared.

<h3>What is area of a figure?</h3>

The window is the shape of a kite. Therefore, the square meters of the glass used for the window is the area of the window(kite).

Therefore,

area of kite = ab / 2

where

  • a and b are the length of the diagonal

Therefore,

a = 18 + 18 = 36 cm

b = 15 + 21 = 36 cm

area of the window = 36 × 36 / 2 = 1296 / 2 = 648 cm²
