Answer:
a - 30.2
b - 271.8
Step-by-step explanation:
60/4=15
60/3=20
9+6.45+2.4+8.15+4.2=30.2
30.2x9=271.8
His hourly rate is $13.75.
Let x be the hourly rate. Since he works 20 hours that week, the hourly wages are given by 20x. We add to that his commission, which is 16% of the $1500 in sales, or 0.16(1500). This totals to 515:
20x + 0.16(1500) = 515
20x + 240 = 515
Subtract 240 from both sides:
20x + 240 - 240 = 515 - 240
20x = 275
Divide both sides by 20:
20x/20 = 275/20
x = 13.75.
If you say its easy, then why don't you figure out yourself? Or ask the teacher?
-100 is rational.
-100 can be turned into a fraction by doing the following...
Just put 1 underneath -100 and you get 
So that means it is rational since it can be a fraction!
Given:
The graph of a function.
To find:
The zeros of this function on the graph.
Solution:
We know that, zeros are the values at which the values of the function is 0. It means, the points where the graph of function intersect the x-axis are know as zeros of the function.
From the given graph it is clear that, the graph intersect the x-axis at two points.
Therefore, the marked points on the below graph are the zeros of the function.
