Samantha is making pancakes. The recipes makes 12 pancakes with some flour, milk, and 4 eggs. Considering the amount of eggs she needs, what is the constant of proportionality?

 1/3

Step-by-step explanation:

If e represents the number of eggs Samantha needs for p pancakes, it appears we're being asked for k in the equation ...

  e = kp

Filling in the given values and solving for k, we have ...

  4 = k·12

  4/12 = k = 1/3

The constant of proportionality is 1/3.

answer: h

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
