Describe how graphs,tables,and equations of nonprortional relationships are different than proportional relationships
Lynna [10]

If two quantities are proportional, then they have a constant ratio. If the ratio is not constant, the two quantities are said to be non-proportional. We will make tables and look at the relationship between the variables to determine proportionality.

Which of the following is an arithmetic sequence?
noname [10]
<h3>Answer:</h3>

1/2, 2, 7/2, 5

<h3>Step-by-step explanation:</h3>

The differences between adjacent terms of an arithmetic sequence are the same.

No sequence in which signs alternate can be an arithmetic sequence. This eliminates the 1st and 4th choices.

The denominators of the 2nd sequence are an arithmetic sequence, meaning that sequence is a "harmonic" sequence, not an arithmetic one. The differences between adjacent terms get smaller and smaller. They are not a constant.

Differences between terms of the 3rd sequence are all 3/2. This is your arithmetic sequence.

Help me please, ps u don't have to answers all of them
Leni [432]
A) To find the surface area of a cube, you have to use the formula 6•a^2
meaning you just have to calculate one side and multiply it by six.
541.5 is the surface area of the cube.
B) To find the surface area for just five sides, you'll be doing the same, except instead of 6 it'll be five.
so multiply 9.5 by itself
you get 90.25
Then you multiply 90.5 by 5
You get 451.25

Unfortunately I'm not sure how to do C. good luck
