The number of square units, A, in the area covered by a bacteria culture is increasing at a rate of 20% every 7 days. If the bacteria culture initially covers an area of 10 square centimeters, which equation can be used to find the number of square units in the area covered by the bacteria culture after d days?

Find two areas greater than 20 square units for which you could use tiles to make a square.

The rate of increase in the number of bacteria in a certain bacteria culture is proportional to the number present. If in 5 hrs the number triples, then in 10 hrs, the number of bacteria present is

If the bacteria in a culture increase continuously at a rate proportional to the number present and initial number is N, then the number present at time t is

A scientist studies Bacteria Culture A, which grows then percent every hour. Bacteria Culture A initially contained 200 microbes, and she models the growth using the equation n=200(m)^(h) , where n is the number of microbes and h is the number of hours. Q. What is the value of m in the equation ?

The rate of increase in the numbers of bacteria culture is proportional to the number present.If initially there were 1000 bacteria and the number doubles in 1 hour,find the number of bacteria after a time of 2 1/2 hours.

A scientist studies Bacteria Culture A, which grows then percent every hour. Bacteria Culture A initially contained 200 microbes, and she models the growth using the equation n=200(m)^(h) , where n is the number of microbes and h is the number of hours. Q. The same scientist also studies another culture, Bacteria Culture B, which grows 15% every hour. The two cultures began at the same time with the same number of microbes. After 20 hours, how many more microbes will becteria Culture B contain than Bacteria Culture A ? (Round your answer to the nearest whole number).

What is the number of pallets, each with an area of 60 square yards, that would be needed to cover a field that in 3 acres in area? (1 acre=4,840 square yards)

The area of a rectangle gets reduced by 80 square units if its length is reduced by 5 units and the breadth is increased by 2 units. If we increase the length by 10 units and decrease the breadth by 5 units, the area is increased by 50 square units. Find the length and breadth of the rectangle.

A straight line forms a right angled triangle with the axes of coordinates . If the hypotenuse is 10 unit and the area of the triangle is 24 square unit , find the equation of the straight line.
