Polygons abcd and a'b'c'd' are shown on the following coordinate grid: what set of transformations is performed on abcd to form a'b'c'd'? a 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left a translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin a 270-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left a translation 1 unit to the left followed by a 270-degree counterclockwise rotation about the origin

(A) rotated 90° and shifted left 1 unit

Step-by-step explanation:

A: (2, -2)

    rotated 90° → (2, 2)

                                    shifted left 1 unit → (1, 2)

B: (4, -2)

    rotated 90° → (2, 4)

                                    shifted left 1 unit → (1, 4)

C: (1, -3)

    rotated 90° → (3, 1)

                                    shifted left 1 unit → (2, 1)

D: (5, -3)

    rotated 90° → (3, 5)

                                    shifted left 1 unit → (2, 5)

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
