The sides of one right triangle are 6, 8 and 10. The sides of another right triangle are 10, 24 and 26. Determine if the triangle are similar. If so, what is the ratio of corresponding sides

Answers

corresponding sides are 6,10 8,24 10,26 now my question is these numbers out side the triangle or in side cuz if so in side u need the out side numbers to determine if is similar or not add the out side numbers then subtract it from 180 to get ur 3rd missing number in the triangle now if there more than 2 triangle wich of (how ever many u got) of triangles find the ones in wich have to the same numbers sooo for example if there's 3 triangles one big one medium and one large find the corresponding sides of the 3 triangles is step one then there should be a missing number in all three triangles add the to first in the triangle then subtract it from 180 to get the missing number then you can determine if the correspond or not then you need to take that outside measures that correspond and put them in the fraction then you will simplify it with the greatest number that can divide the two numbers in the fraction

What times 10 equals 400

Answers

The answer is 40

10
x 4
----
00
+400
-------
400

So this is your equation to figure it out: n*10 = 400
To get rid of the times 10, you need to divide both sides by 10.
Now you have n*10/10 = 400/10
The 10's on the left cancel each other out, so now you have n=400/10
400 divided by 10 is 40
ANSWER: 40

Answer:

Step-by-step explanation:

State whether every point on the graph is a solution of the equation. Explain why or why not.

3x – 2y = –6

A.
Every point shown on the graph is a solution of the equation because when the coordinates of the points are substituted into the equation, the equation is true for all the points.

B.
Every point shown on the graph is not a solution of the equation because when the coordinates of the points are substituted into the equation, the equation is not true for all the points.

Answers

I believe that the answer is A.

Every point shown on the graph is a solution of the equation because when the coordinates of the points are substituted into the equation, the equation is true for all the points.

because if we take the points (0,3) from the picture and put in them in the equation, so it will gives you;

3x – 2y = –6

3*0-2*3=-6

-6=-6

hope you understand it :)
