What set of transformations is performed on triangle rst to form triangle r’s’t’? a. a 90-degree counterclockwise rotation about the origin followed by a translation 2 units left b. a 270-degree counterclockwise rotation about the origin followed by a translation 2 units to the right c. a translation 2 units down followed by a 90-degree counterclockwise rotation about the origin d. a translation 2 units down followed by a 270-degree counterclockwise rotation about the origin

D. A translation 2 units down followed by a 270-degree counterclockwise rotation about the origin

Step-by-step explanation:

The given triangle has vertices at R(3,4), S(1,1), and T(5,1)

Translating the the vertices down by 2 units, we apply the rule;

Rotating the resulting vertices through an angle 270 degrees counterclockwise, we apply the rule:

Therefore the correct choice is D.

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
