The perimeters of two similar triangles are 25 cm and 15 cm respectively. If one side of the first
Vanyuwa [196]

Answer:

5.4cm

Step-by-step explanation:

In similar triangles, the perimeter of the triangles will be in the ratio of their corresponding sides.

The ratio of their perimeter is  

perimeterofΔ2          15

---------------------   = -------------

perimeterofΔ1           25  

So, the side of triangle 2 will be  

  9  *  15                  15

----------------  =   --------------

​  sideofΔ2                25

=  

​⟹side of Δ2=           25  / 9∗15         =5.4.

A ratio is a rate. Sometimes always or never true
sineoko [7]
By definition, the ratio is the expression that would allow us to express the quotient of two numbers and/or any mathematical expressions. Let us take for example, numbers 4 and 5. The ratio between these values is 4/5. 

The statement given above, "A ratio is a rate" is only sometimes true. This is only true when the unit of measurement of the denominator is in terms of time (seconds, minutes, hours, years, etc) because this would tell us how fast is something being done, consumed, etc. Example, the speed or rate of a car is 4 meters / 5 seconds.

The system of equations shown is solved using the linear combination method
andriy [413]

Answer: When a system of two linear equations gives an answer of 0=0, there are infinitely many solutions. It also means that the graph represents parallel lines, so the answer is the third choice.

Step-by-step explanation: When it comes to systems of equations in algebra, you will see three types of solutions:

1. When you get an exact value & number for x and y, the system has <u>one solution</u> and is consistent/independent.

2. When you get 0=0 like in this case, the system has <u>infinitely many solutions</u> and is consistent/dependent.

3. When you get numbers that are not equal, for example, 3\neq 5, you have <u>many solutions</u> and the system is inconsistent/independent.
