Carla has 1 gallon of paint. She is going to pour it into a paint tray that measures 10 inches wide, 10 inches long, and 7 cm deep.

(1 gallon = 231 in3, 1 inch = 2.54 cm) Thanks

ybarrap · Answer

So do you want to know if that gallon of paint will fill the tray without spilling over then?

anonymous · Answer

Yes

ybarrap · Answer

Ok. let's figure out the volume of the tray: Length x Width x Height: 10 * 10 * 7 = ?

That's the volume of the tray in cubic inches.

anonymous · Answer

140

ybarrap · Answer

But we need to convert that 7 cm to inches right. So 7 cm * 1 inch/2.54 cm = 7/2.54 = depth of tray in inches.

ybarrap · Answer

So the volume of the tray is really, 10 * 10 *7/2.54 = ? This will then be in cubic inches.

anonymous · Answer

55.11?

anonymous · Answer

Which of the following scenarios will happen?

 The paint will not fill the tray by 44.59 in3.

 The paint will not fill the tray by 469 cm3.

 The paint will fill the tray exactly.

 The paint will overfill the tray by 44.59 in3.

ybarrap · Answer

Compare that to the volume of a gallon, which is 231 cubic inches. Is 10*10*7/2.54 = 276 greater or less than a gallon of paint?

anonymous · Answer

greater

ybarrap · Answer

anonymous · Answer

Kenya is reserving a room in a hotel in France where they use euros (€). The room charge is €75. Suppose the conversion rate is €1 = $1.298. What is the cost of the room in dollars?

 $57.78

 $77.56

 $97.35

 $129.80

ybarrap · Answer

For any type of conversion from one unit to the other use this trick:

$ \cfrac{$1.29}{€1}\times€75 = \cfrac{$1.29}{\cancel{€}1}\times\cancel{€}75=  $?
Notice how the units I'm converting FROM canceled and leaves me with the units I'm converting TO.

ybarrap · Answer

You are left with just 1.29 x 75 = ? In dollars.
