The answer is        A .2d/T
Since d is directly proportional to the heat lost it should be the numerator
since T is inversely proportional to the heat lost it shoudl be the denormirator
 that is      1/T ;         2 is the constant
the actual formula is        R = kd/T

A pottery maker an make 24 vases in 8 days, if the pottery maker works 6 hours each day, how long does it take to make 1 vase???
kolbaska11 [484]


first of all you must find out how many vases he makes per day;

24 ÷ 8 = 3 vases per day

So if he makes 3 vases per day now to find how much time he takes per vase you must divide the number of hours he works per day by the number of vases he makes per day;

6 hours ÷ 3 vases =

6 ÷ 3 = 2

so your final answer would be: 2 hours per vase

Finding Slope On a coordinate plane, a line goes through points (0, 1) and (4, 2). What is the slope of the line? m =
ivolga24 [154]

Answer:

slope = \frac{1}{4}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (4, 2)

m = \frac{2-1}{4-0} = \frac{1}{4}
