Answers
Answer 1
Answer:
I believe it is 84 cm^2. It is the only reasonable answer with logic I can come up with.
the 3rd one because you need to find the area of the square and times it by 3.
Arrange the following numbers in ascending order: 2/9, 21%, 4.3 x 10-2, -3/5, 0.023
Answers
2/9=0.223 21%=0.21 4.3x10-2=41 -3/5=-0.6 0.023 arrange these in ascending order and you have -3/5=-0.6 21%=0.21 0.023 2/9=0.223 4.3x10-2=41
so in ascending order they are -3/5, 21%, 0.023, 2/9, 4.3x10-2

one half liter of lemonade concentrate is added to 3 liters of water. how many 1/3 liter servings of lemonade are made.
Answers
The way I understand this, is that we will have 3 (liters of water) +0.5 (half a liter of lemonade) =3.5 liters of liquid
so the question would be: how many times does fit into 3.5?
I count this like this:
if you want to divide by a fraction, you need to multiply by the reverse of it.
so the answer is: 10 servings of lemonade ( and a little bit will be left over for half a serving).

Dmitri wants to cover the top and sides of the box shown with glass tiles that are 3 5 mm square How many tiles does he need 20 cm 15 cm
Answers
lets split the box in pieces and then add: top = 20*15 = 300 sidesA = 2*20*9 = 360, is multiplied by 2 cause there are 2 sides like this sidesB = 2*9*15 = 270, is multiplied by 2 cause there are 2 sides like this so in total we have: total = 300 + 360 + 270 = 930 cm^2 if we express this quantity in mm^2 we have: 1cm² = 100 mm²total = 930*100 = 93000 mm^2 so if the tiles are 5 mm^2 we need: total tiles = 93000/5 = 18600 we need 18600 tiles of 5 mm^2
