Quadrilateral FLAG has coordinates F(1,5), L(6,3), A(3,-1), and G(-2,1). Which
Anettt [7]

Answer:

  • B. Quadrilateral FLAG is a parallelogram because opposite sides are parallel.

Step-by-step explanation:

<em>Refer to attached.</em>

Plot the point and connect in order FLAG.

<u>We see </u>

  • FL ║ GA
  • GF ║ AL
  • FA and GL are not perpendicular

<u>All the above can be confirmed by calculating the slopes:</u>

  • m(FL) = (3 - 5)/(6 - 1) = -2/5
  • m(GA) = (1 + 1)/(-2-3) = -2/5
  • These are same.
  • m(GF) = (5 - 1)/(1 + 2) = 4/3
  • m(AL) = (3 + 1)/(6 - 3) = 4/3
  • These are same
  • m(FA) = (-1 - 5)/(3 - 1) = -3
  • m(GL) = (3 - 1)/(6 +2) = -1/4
  • These are negative but not reciprocal

The quadrilateral is a parallelogram.

Correct choice is B

Pat has been assigned the job of picking apples from the family orchard. He could do the job alone in 8 hours. He knows that his
schepotkina [342]

Answer:

3.7 hours

Step-by-step explanation:

Pat could do the job alone in 8 hours.

Patti could do the job alone in 7 hours

Output = Rate * time

Let the rate at which pat does the work = Rp

Let the rate at which Patti does the work = Rt

Let X be the total output

Rp * 8 = X

Rp = X/8

Rt * 7 = X

Rt = X/7

If both pat and Patti pick apples, we have

(Rp+Rt)T = X

(X/8 + X/7)T = X

[(7X + 8X)/56]T = X

[X(7+8)/56]T = X

Divide both sides by X

[(7+8)/56]T = 1

(15/56)T = 1

T = 56/15

T = 3.7 hours
