12 in | 11 in 10 in | 9 in can you find the rate of change for the two sets of points?

If we are to treat these as two ordered pairs, then the rate of change is 0.90625

Step-by-step explanation:

To find this, use the slope equation with the ordered pairs.

m(slope) = (y2 - y1)/(x2 - x1)

m = (11 9/16 - 9 12/16)/(12 - 10)

m = (1 13/16)/2

m = 1.8125/2

m = 0.90625

Now we know that this could be a function since we have a constant slope.

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
