With the origin as the center of dilation, rectangle pqrs will be dilated by a scale factor of 1/3 to form rectangle pqrs'. what

sergeinik [125]

For a dilation centered around the origin
Dk (x,y) = (kx, ky)
So let's say you have a rectangle PQRS where
P = (0,0)
Q = (4,0)
R = (4,4)
S = (0,4)
To get the dilation of this PQRS to P'Q'R'S' with scale factor 1/4 you multiply every coordinate by 1/4.
P' = (0.0)
Q' = (1,0)
R' = (1,1)
S' = (0,1)
The new cordinates for point q(1,0)

Eduardo says that an increase from 10 to 40 is 300% therefore a decrease from 40 to 10 must be a 300% decrease do you agree with

attashe74 [19]

Answer:

Eduardo's second statement is wrong.

Step-by-step explanation:

Eduardo says that an increase from 10 to 40 is 300% which is true. Because there is an increase by (40 - 10) = 30 and the percent of increase is calculated with respect to 10.

So, % of increase = $\frac{30 \times 100}{10} = 300$ %.

But when we consider a decrease from 40 to 10, then the decrease is by (40 - 10) = 30, but the percent of decrease will be calculated with respect to 40.

Therefore, the % decrease = $\frac{30 \times 100}{40} = 75$ %.
