On Thursday Mabel handled 90 transactions. Therefore, we determine 19/6 = 4/27 is not proportion so, the answer is false.ġ1. Which method did you use to determine whether this proportion is true or false? Therefore, unit used for this case = hours/mile.ġ0. Similarly, if we divide 2 by 80 then, we get time taken to cover 1 mile. Therefore, Jody drove 40 miles in 1 hour.īut if we divide total time by total distance then, we get time taken to cover 1 mile. Total distance 80 miles divided by total time 2 hours = 80/2. Here, speed = distance covered in 1 hour. When total distance is divided by total time we get the speed. If we divide 2 by 80 what information would this give us? Give an interpretation of the rate. The units for this rate are miles per hour (mi/hr). Dividing 80 by 2 tells us how many miles Jody drove in each hour. Suppose that Jody drove 80 miles in 2 hours. Similarly, the cost a pizza depends on its area not its diameter.ĩ. So, we can clearly say that area of a circle is proportional to the square of the diameter. Do you agree with his reasoning? If not, explain why not.Īnd we know that area of a circle depends on the radius.Īrea of a circle = πr 2, here pi (π) is constant. Tommy says the smaller pizza is a better buy because the larger pizza is twice as big and more than twice as expensive. If x -1 – 1 is divided by x – 1 the quotient is: The side AC extended through C intersects the circle at D. A circle of radius 10 inches has its center at the vertex C of an equilateral triangle ABC and passes through the other two vertices. The roots of the equation ax 2 + bx + c = 0 will be reciprocal if a = c.ģ. We know that, product of the roots of the equation = c/a. Let k be one of the root of the given equation.ġ/k will be the other root of the given equation. The roots of the equation ax 2 + bx + c = 0 will be reciprocal if: The number of legs was 14 more than twice the number of heads. Let the number of chicken be y and their legs be 2x. Let the number of cows be x and their legs be 4x. In a group of cows and chickens, the number of legs was 14 more than twice the number of heads.
