The fish box is 6 * 6 * 4 = 144 cubic square inches
144 = one box so divide 3456 by 144 to see how many boxes will go into the aquarium
3456 / 144 = 24
24 boxes of fish food could fit in the aquarium
Profit = revenue (income) - expenses
600 = 120x - 300
600 + 300 = 120x
900 = 120x
900/120 = x
7.50 = x ....this is how much 1 kg costs
so to cover her weekly expenses of 300, she would have to sell :
300/7.5 = 40 kg of cumin <===
Answer:
only the first two are correct (top to bottom)
Step-by-step explanation:
For the first one, we know this because the the opposite of -3.5 is 3.5, and the rightside of zero is positive.
For the second one, we know the expression, -(-3.5) is equal to 3.5 because whenever there is a minus before a parentheses and there's a minus sign inside of the parentheses it automatically becomes positive.
For the third one, we know it's incorrect because the opposite of a positive is a negative.
Lastly, for the last one, (the most bottom one) we know that the opposite of zero is negative zero.
Hope this helps!!!
