Alchen [17]

Answer: Andy covers all the walls of his kitchen using 6 rolls of a wallpaper.

To Find:

Number of rolls used per wall.

Solution:

Since, we know that the shape of a kitchen is a cuboid.

And a cuboid has total 6 faces, with 4 walls, one roof and one floor.

So, total number of walls in Andy's kitchen = 4

Now, it is given that he uses 6 rolls of wallpaper to cover 4 walls completely.

Number of rolls used per wall =

yan [13]

Answer: He will receive only $55080 against the fire insurance that caused damage the property.

Explanation:

Since we have given that a house worth $250,000 has a coinsurance clause of 90 percent .

But the owner insure the property for $191,250.

That means the owner does not insure the property for his full value ,

Amount incurred on fire that caused damage =$80,000

Amount he will receive against his insurance is given by

$80000\times \frac{90}{100}\times \frac{191250}{250000}\\\\=\$55080$

Hence, He will receive only $55080 against the fire insurance that caused damage the property.
