On a scale drawing of Caleb’s house, the four bedroom walls each measure 10 inches wide by 6 inches tall. The scale of the drawing is 1 inch = 1.5 feet. Caleb will paint all four walls. If a gallon of paint covers 250 square feet, how many gallons of paint will Caleb need? A. 1 gallon B. 2 gallons C. 3 gallons D. 4 gallons

Explanation:

1 inch = 1.5 feet

10 inches = 15 feet (multiply both sides by 10)

6 inches = 9 feet (multiply both sides of the first equation by 6)

The scale drawing is 10 inches by 6 inches, which corresponds to real life dimensions of 15 ft by 9 ft.

The area of the one wall is 15*9 = 135 square feet.

There are four identical walls of equal area, so 135*4 = 540 square feet is the total area we need to paint.

1 gallon = 250 square feet

0.004 gallon = 1 sq ft  (divide both sides by 250)

2.16 gallon = 540 sq ft (multiply both sides by 540)

You'll need exactly 2.16 gallons of paint to cover all four walls.

Since Caleb cannot buy 0.16 of a gallon, he'll need to buy an additional gallon to cover the fractional portion. So he'll need to buy 3 gallons of paint and he'll have 3-2.16 = 0.84 gallons of paint left over.

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
