Determine whether the following data should be represented on a graph as one-dimensional, two-dimensional, or three-dimensional. the number of fish in each aquarium at a pet store

The following data should be represented on a graph as : One-dimensional.

Step-by-step explanation:A data is represented on a graph as one-dimensional if only one variable is associated with it.A data is represented on a graph as two-dimensional if two variables are associated with it .

Example is: Distance vs time graph.

and corresponding definition holds for three-dimensional.

Example-- when a a graph of two-functions is embedded to one then we get a three-dimensional graph.

Now, the data:

The number of fish in each aquarium at a pet store will be represented by a one-dimensional graph since,there is only one variable i.e. number of fishes associated to it.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
