Triangle PQR is scaled up by a factor of 2 and then reflected about the y axis and is named as triangle XYZ. Which statement is true?

Answers

Answer 1

[tex]\triangle PQR[/tex] is not congruent to [tex]\Delta XYZ[/tex] because a non-rigid motion was performed. (Correct choice: B)

A motion is rigid if and only if the Euclidean distance between any two points of an affected geometrical figure is conserved, there are four operations considered for rigid motion:

TranslationRotationReflectionGlide reflection

Thus, scaling is not a rigid motion as Euclidean distances between any two points of the figure are altered. In a nutshell, [tex]\triangle PQR[/tex] is not congruent to [tex]\Delta XYZ[/tex] because a non-rigid motion was performed. (Correct choice: B)

Explain why the dividing-out method is incorrect. You may want to start with a simpler expression and work your way up to polynomials. (For example, compare fraction numerator 3 left parenthesis 5 right parenthesis over denominator 3 end fraction and fraction numerator 3 plus 5 over denominator 3 end fraction.)
Explain when you can cancel a number that is in both the numerator and denominator and when you cannot cancel out numbers that appear in both the numerator and the denominator.

Answers

For this exercise we must correct the error of the given fraction, differentiating the properties of addition and multiplication, so:

1)This error occurs frequently because when simplifying in a multiplication or division it cannot be done in the operations of subtraction and addition.

2)As this error is very common, it has probably already occurred. But one way to resolve this is to pay attention and redo the math.

to understand this error we have to:

[tex]\frac{(3)(5)}{3} = 5[/tex]

In the case of multiplication the 3 of the numerator can be simplified with the 3 of the denominator, the other case will be:

[tex]\frac{3+5}{3} = \frac{8}{5}[/tex]

In the case of addition or subtraction, you should always keep the denominator.

how do you solve 25/6 divided by 25/12?

Answers

ANSWER:

Step-by-step explanation:

Nayeli is driving on a long road trip. She currently has 14 gallons of gas in her car. Each hour that she drives, her car uses up 1.5 gallons of gas. How much gas would be in the tank after driving for 4 hours? How much gas would be left after t hours?

Answers

Answer:

8 gallons

Step-by-step explanation:

Total gas in the car = 14 gallons

Each hour gas usage = 1.5 gallons

Total hours traveled = 4 hours

Left gas after 4 hours

= 14-1.5(4)

=14-6

=8 gallons

Left gas after t hours

=14-1.5t

Hence the answer is after 4 hours, 8 gallons are left after t hour(s) 14-1.5t

The amount of gas in the tank after driving for 4 hours will be 6 gallons. The amount of gas that is left after t hours will be 14 - 1.5t.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Nayeli is driving on a long road trip. She currently has 14 gallons of gas in her car. Each hour that she drives, her car uses up 1.5 gallons of gas.

The amount of gas in the tank after driving for 4 hours will be

⇒ 1.5 x 4

⇒ 6 gallons

The amount of gas that is left after t hours will be

⇒ 14 - 1.5t

The amount of gas in the tank after driving for 4 hours will be 6 gallons. The amount of gas that is left after t hours will be 14 - 1.5t.
