The graph models the amount of radioactive element present over the cours of a 2 minute experiment. What is the avearge rate of change of the amount of the element over the 2 minute experiment?

a -12.5 g/min
b 2 g/min
c. 2.5 g/min
d. -3.75 g/min

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
