We're given s = 8^(3/2) as the side length. If we square both sides then we have s^2 = [8^(3/2)]^2 = 8^3. Note how the '2's effectively cancel out. This is because we multiply the exponents (3/2) and 2 to get (3/2)*2 = (3/2)*(2/1) = (3*2)/(2*1) = 6/2 = 3.

So A = s^2 = 8^3 = 512 is the area of the square

If you buy ice cream in 1 liter each tub cost $2 you can fill ten cones from each tub each empty cone cost 5 cents you can plan

weqwewe [10]

Answer:

You make 5.50 each 10 servings or tub you use. To find how much in a day multiply $5.50 by the number of tubs you use or number of 10 servings you sell.

Step-by-step explanation:

You buy a 1 liter tub for $2 and fill ten cones with the tub costing 10*0.05 = 0.50 for the cones. This means your total cost is $2.50 per tub (or 10 servings).

But you plan to sell the servings for 0.80 cents each. This means for 1 tub or 10 servings you'll make 10*0.8 = $8.00. You'll make $8.00.

Your profit is how much you make minus your costs.

$8.00 - 2.50 = $5.50.

You make 5.50 each 10 servings or tub you use.
