I believe the answer is 50, hope this helps
1.)By dividing the given costs per pound (6÷9, or 12÷18) you will get the answer of 1.5. This means it is $1.50 per pound.
2.)If you buy 9 pounds of tomatoes at a $1.50 a pound, you have to multiply to find out how much you get. 9×1.5=13.5
They paid $13.50
3.) To find how many pounds you can buy for $19.50, you have to divide 19.5÷1.5 and you will get 13 pounds.
Answer:
The area covered by the planters is 113.6 square inches.
Step-by-step explanation:
Assuming that the dimmensions of the greenhouse are 4 1/4 by 1 2/3 inches. We first need to convert them from mixed fractions to normal fractions, we do that by summing the integer part to the fraction one. We have:
length = 4 + 1/4 = 16/4 + 1/4 = 17/4 inches
width = 1 + 2/3 = 3/3 + 2/3 = 5/3 inches
The area of the greenhouse is given by:
area = length*width
area = (17/4)*(5/3) = 85/12 = 7.1 square inches
Since there is an array of 4x4 there is a total of 16 greenhouses and it's total area is 16*7.1 = 113.6 square inches
