Step-by-step explanation:
Given: a graph
To find: the average rate of change of the amount of the element over the 10-minute experiment
Solution:
A rate of change of one quantity with respect to another quantity is known as rate of change. If y is the dependent variable and x is the independent variable then average rate of change = change in y /change in x.
From the graph,
change in x (time) = minutes
change in y ( amount of the element) = g
So, average rate of change =

Answer:
A = 10.9 cm^2
Step-by-step explanation:
If a circle has a radius of 13 and a sector defined by a 7.4 degree arc, the area, in cms, of the sector is 10.9 cm^2 or 10 cm^2 to the nearest tenth.
You need to find out 0,5$ is what pourcentage of 2$
So you need to do a cross product :
0,5 → 2
× → 100
(0,5 × 100) ÷ 2 → 50 ÷ 2 = 25%
So the answer is : The percent markup that is being charged is 25%!
Another way to see it is :
There is 4 times 0,5$ in 2$
So if you take 1/4 of 2$ it’s the same thing as saying that you’re taking 0,5$.
And 1/4 = 25% :)!
