Two right triangles on a coordinate plane are similar but not congruent.Each of the legs of both triangle are extended by 1 unit,creating two new right triangles.Are the resulting triangles similar? explain using an example

Answers


Virtually every time you try this stunt, the new triangles
are NOT similar.

Example:

Triangle A₀ . . . legs = 3 and 4;  hypotenuse = √25  = 5 .
Triangle B₀ . . . legs = 6 and 8;  hypotenuse = √100 = 10 .

Ratio of short legs = 6/3 = 2
Ratio of long legs  = 8/4 = 2
Ratio of hypotenuses = 10/5 = 2
The triangles are similar. 

Add 1 unit to all legs:

Triangle A₁ . . .  legs = 4 and 5;  hypotenuse = √41
Triangle B₁ . . .  legs = 7 and 9;  hypotenuse = √130

Ratio of short legs = 7/4 = 1.75
Ratio of long legs  = 9/5 = 1.8
Ratio of hypotenees = √(130/41) = 1.78 .

New triangles are NOT similar.

I think this ONLY works when the original triangles are
congruent, so the ratio of their similarity is 1:1. 
When each leg of both triangles is extended by the same
amount, they are still congruent.
 
But the question stipulates that they are NOT congruent.
So the answer to the question is:   No.  Never.
 
They are similar, by SSS. This shows that the sides are all similar but may not be congruent. And they started out similar, and they have the same scale factor. If you had one more angle besides the 90, you would be able to figure out the angles inside and have AA to justify. 
Sorry if this is a bad explanation. 

A coin-operated machine sells plastic rings. It contains 6 yellow rings, 11 blue rings, 15 green rings, and 3 black rings. Suzy puts a coin into the machine. Find the theoretical probability that she will get a green ring. Express your answer as a fraction in simplest form.

Answers

1) you have to add all the rings together to find the denominator

6 + 11 + 15 + +3 = 35

2) the numerator is the amount of rings of the certain color you are trying to find the probability of

15

3) find the theoretical probability! 15/35

4) simplify

15/35 (divide both by 5) = 3/7

The Track Team has 72 water bottles. They pack them 10 to a box. How many boxes do they fill? How many water bottles are left over?

Answers

10 x 7 = 70 ( water bottles each box )

= 2 more left overs ( 72 water bottles in total )

How many boxes did they fill?

They filled 7 boxes.

How many water bottles are left over?

There are 2 more water bottles that are left over.

Solve open parentheses square root of 7 close parentheses to the 6 x power = 49x−6.x = negative 21 over 2
x = −6
x = negative 6 over 5
x = −12

Answers

Answer:

Option D is correct.

x = -12

Step-by-step explanation:

Solve:  (√(7))^(6x) = 49^(x-6)

We can write 49 as:

49 = 7 \cdot 7 = 7^2

using exponent rules:

\sqrt[n]{a^m}=a^{(m)/(n)}

(a^m)^n = a^(mn)

Apply this rules on the given equation:

((7)^{(1)/(2)})^(6x) = (7^2)^(x-6)

7^{(6x)/(2)} = 7^(2(x-6))

Simplify:

7^(3x) =7^(2x-12)

On comparing both sides we get;

3x = 2x-12

Subtract 2x from both sides we get;

x = -12

Therefore, the value of x is -12
The equation is not setup properly, possibly it is your teacher's fault.

From external research, I would say the answer is x = -12.

What is the smallest negative integer? Explain.

Answers

There is an INFINITE amount of numbers out there, including BOTH positive and negative.
So, the more closer you go to infinite (that is toward bigger numbers EX: -100,000,000) the smaller the number gets while in the positive direction, the closer the numbers are close to 0, the numbers are small (EX: 1)
Since there is an infinite amount of numbers, there is not really a definite answer to this question.
