Identify the percent of change as an increase or a decrease. 54 to 38 Increase Decrease Question 2 Find the percent of change. Round to the nearest tenth of a percent if necessary. %

  decrease of 29.6%

Step-by-step explanation:

The percentage change can be calculated as ...

  percent change = ((new value)/(old value) -1) × 100%

  = (38/54 -1) × 100%

  = -0.2963 × 100%

  = -29.6%  . . . . . . . . . negative means decrease

54 to 38 is a decrease of 29.6%.

29.6% increase

Step-by-step explanation:

Percent of change is calculated by

(old number - new number) / old number x 100

54 - 38/54 ×100

= 16/54 × 100

=29.6%

the image of (6, 9) under a dilation is (4, 6). the scale factor is

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
