Triangle ABC has Vertices A(1, 2), B(3, 5), and C(4, 3). Using the origin as the center of dilation, Triangle ABC is dilated by a scale factor of 3 to create Triangle A ′ B ′ C ′ . Which statement can be used to justify that Triangle ABC is similar to Triangle A ′ B ′ C ′ ?

Answers

Answer:

AA ≅ AA postulate

Step-by-step explanation:

Given

[tex]A=(1,2)[/tex]

[tex]B = (3,5)[/tex]

[tex]C = (4,3)[/tex]

[tex]k = 3[/tex] --- scale factor

Required

Determine which statement that justifies the similarities between ABC and A'B'C'

When ABC is dilated by a scale factor of 3 to form A'B'C', the sides A'B'C are 3 times as large as the sides of ABC.

However, all three angles of both triangles remain the same. This is so, because dilation do not affect angles.

So, a statement that can be used to justify the similarities is:  AA ≅ AA

A carton of milkshake comped with 25% extra free. A normal size carton is 320ml calculate the volume of milkshake in the larger carton. find 25% of 320

Answers

Step 1: Our output value is 350.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$350=100\%$.

Step 4: Similarly, $x=25\%$.

Step 5: This results in a pair of simple equations:

$350=100\%(1)$.

$x=25\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{350}{x}=\frac{100\%}{25\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{350}=\frac{25}{100}$

$\⇒x=87.5$

Therefore, $25\%$ of $350$ is $87.5$

ill tell em to ya right now


Jorge’s weight change was approximately 5%.

Marie’s weight change was approximately 14%.

Marie had the greater percent change.

Jorge had the greater percent change.

Marie’s weight change was approximately 1.4%.


#edge2021

Answers

Answer:

1 ,2, and 3

Step-by-step explanation:

Jorge's weight percent decrease is (190-180)÷190, or amount of change/original amount. Simplified, 10÷190=5.2637157894...%, approximately equal to 5%. The first option is correct. Marie's percent decrease is (175-150)÷175. Simplified, that is 25÷175=14.2857142857...%, which is about 14%. The second option is correct. Clearly, we can tell that Marie had the greater percent change, about 14% to about 5%. Also clearly, Jorge did not have the greater percent change, so we can tell Option 4 is wrong. We already know that Jorge's change is about 5% and Marie's is about 14%, so they can't be about 0.5% or about 1.4%. Options 5 and 6 are incorrect. The correct answers are 1, 2, and 3.

Hope this helps you!
