A 27 foot piece of cotton cloth costs $45.63 What is price per yard

  $5.07 per yard

Step-by-step explanation:

There are 3 feet in a yard, so 27 feet is 27/3 = 9 yards. To find the price per yard, divide the price by the corresponding number of yards:

  $45.63/(9 yd) = $5.07/yd

The price per yard is $5.07.

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
