It takes them 208 minutes to paint 20 walls.
Answer:
We can determine if the graph shows a function by using the vertical line test.
If we draw a vertical line and there are 2 or more points on that line than the graph is not a function. This is because each x value has one corresponding y value. If an x value has more corresponds to more than one y value than the relation is not a function.
If we were to draw a vertical line at x = 5, 2 points would be one that line meaning that the x value 5 corresponds to more than 1 y value, therefore the graph does not show a function.
Answer:

Step-by-step explanation:
Because the electro has a smaller mass than the mass of the proton, scientific notation is usually used so that the numbers are on the same "scale" but if we see the scientific notation we may be able to identify which is greater and which is less, due to that the exponent is less the number is smaller and on the contrary if the number is greater, it is a larger number.
In the image I leave an example of the use of scientific notation in this area
Perimeter = 72m
length = x
width = x - 4
P = 2l + 2w
72 = 2x + 2(x - 4)
72 = 2x + 2x - 8
72 = 4x - 8
72 + 8 = 4x
80 = 4x
80/4 = x
x = 20
Therefore, the length = 20m and width = 16m
Answer:
Carbon Bonds are a source of energy
Step-by-step explanation:
If this were a free answer response question, I would say that the reason would be that carbon can form bonds with many other element, but it wasn't there, so the first option is the closest to my answer.
