Quadrilateral ABCD has coordinates A (3.1), B (4.4), C (7.5), D (6,2). Quadrilateral ABCD is a

rectangle, because opposite sides are congruent and adjacent sides are perpendicular

square, because all four sides are congruent and adjacent sides are perpendicular

parallelogram, because opposite sides are congruent and adjacent sides are not perpendicular

mombus, because all four sides are congruent and adjacent sides are not perpendicular

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

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
