Answer and Step-by-step explanation:

<u>For question A) </u>

ABC is similar to PQR because of the AA similarity postulate. This postulate states that <u>if any two angles in a triangle are congruent to the other two angles in a triangle, then the triangles are similar. </u>

<u>For question B) </u>

The area would be k times more than the area of ABC.

The area of a triangle is bh/2, or base times height, divided by 2.

And since they both have 4, the one with the k will be k times greater.

Hopefully this helps!!

Answer:

  • (a) yes
  • (b) Area of ΔPQR is k² times greater

Step-by-step explanation:

(a) As per the diagram, the triangles are similar.

  • ∠B ≅ ∠Q and ∠C ≅ ∠R

ΔABC ~ ΔPQR as per AA similarity postulate (two congruent angles)

(b) The area is the product of two dimensions. Area of ΔABC

  • A = 1/2bh

Since each side of ΔPQR is k times greater than corresponding sides of ΔABC, the base and height will be both k times greater.

<u>So the area of ΔPQR will be:</u>

  • A = 1/2bkhk = 1/2bh*k²

The area of PQR is k² times greater than the area of ΔABC

Kiera used place value and the distributive property to find the product of 12 and 597. Her work is shown below. 12(597) = 12(50
olya-2409 [2.1K]

Answer:

(90)(7) ⇒ the error was multiplying 90 and 7.


Step-by-step explanation:

12(597) = 12(500 + 90 + 7)

            = 12(500) + (90)(7)

             = 6000 + 630

                = 6,630

The part in bold shows where the error is. It was not correct to multiply 90 and 7.

The process was to proceed as follows:

12(597) = 12(500 + 90 + 7)

            = 12(500) + 12(90) + 12(7)

             = 6000 + 1080 + 84

                = 7,164

convert to inproper fracton first

1 and 1/2=1+1/2=2/2+1/2=3/2

3 and 1/2=3+1/2=6/2+1/2=7/2


3/2dozen=7/2cups
times 2 both sides
3dozen=7cups
divide by 3 both sides
1dozen=7/3cups=2 and 1/3 cup
