anyone know inverse operations, cause I am confused, I looked online and it said
Example: 20 + 9 = 29 can be reversed by 29 − 9 = 20 (back to where we started)
And the other way around:

Example: 15 − 3 = 12 can be reversed by 12 + 3 = 15 (back to where we started)
so like when do we do the 2nd way or can we just do either one of them???

Answers

Answer:

For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.

Inverse operations are also very helpful for linear equations.

To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.

Ex:

13 - 2 = 11    (now change plus to minus)

13 + 2 = 11      (not the answer yet)

Now we switch the first number with the answer!

11 + 2 = 13

Hope this helped, I tried to explain it easily.

11+2=13 that’s the answer maybe

Do 2 or more shapes with the same perimeter have to have the same area? Explain with examples. AND Do 2 or more shapes with the same area also have to have the same perimeter? Explain.

Answers

Yes. Take for example a square and an ellipsis with the same perimeter. The family of ellipses with the same perimeter can have any area between that of a circle to zero (if it is extremely “thin” i.e. if its eccentricity is large). The circle has the maximum area of any other shape with the same perimeter, so the square has the same area of one of the intermediate ellipses.

In a laboratory experiment, two mice will be placed in a simple maze with one decision point where a mouse can turn either left (L) or right (R). When the first mouse arrives at the decision point, the direction it chooses is recorded. Then, the process is repeated for the second mouse.

The tree diagram should be drawn where the first stage represents the decision made by the first mouse and the second stage represents the decision made by the second mouse.

Determine all four possible decision outcomes for the two mice.


Using the information from the previous problem, answer the following question.

If the probability of turning left is 0.5 and the probability of turning right is 0.5 for each mouse, what is the probability that only one of the two mice will turn left?

an isosceles triangle is when 2 angles are the same measure. an triangles angle equal to 180 degrees. therefore angle A is 80 degrees as well as angle B equals 80 degrees. since the angles of a triangle equal to 180 you subtract the two known angles to find angle C. So 180-80-80 which equals to 20.


Therefore angle C=20 degrees
