If rectangle ABCD is dilated by a scale factor of 1.5 with a center of dilation at vertex A, how does the area of A'B'C'D' compa re with the area of ABCD?
2 answers:
Answer:
A’/A = 2.25
Step-by-step explanation:
Let the length and width of ABCD be l and w respectively.
A = lw
=====
For rectangle A’B’C’D’
l’ = 1.5l and w’ = 1.5w
A’ = l’w’
A’ = 1.5l × 1.5 w
A’ = 2.25 lw
=====
A’/A = 2.25lw/(lw) Cancel lw
A’/A = 2.25
The area of the dilated rectangle is 2.25 times that of the original.

Lets x = the number of songs
The product of the number of songs and $0.99 = 0.99 times x = 0.99x
The product of the number of songs and $0.99 is $7.92:
=
0.99x = 7.92

Answer: 1/10
Step-by-step explanation:
At the end of the day, she still had 2/5 of the book to read. Which meant that she had read 3/5 of the book. Since she read 1/2 of the book in the day, we would read 3/5 - 1/2 = 6/10 - 5/10 = 1/10 of the book at night.
