Find MQ in parallelogram LMNQ .
Liula [17]

Answer:

MQ = 16.4

By the <u>Parallelogram Diagonals Theorem</u> , MP = <u>PQ</u>

So MQ = 2 · <u>MP</u>

<u />

Step-by-step explanation:

<u>Parallelogram Diagonals Theorem</u>

The diagonals of a parallelogram bisect each other, i.e. they divide each other into <em>two equal parts</em>.

P is the point of intersection of the diagonals.

Therefore, MP = PQ and LP = PN

If MP = 8.2, then PQ = 8.2

⇒ MQ = 8.2 + 8.2 = 16.4

A painter is painting a rectangular wall that measures 23.6 ft by 19.2 ft. Each gallon can of paint covers 200 square feet. What
ludmilkaskok [199]

Answer:

3 gallons

Step-by-step explanation:

Length of the rectangular wall = 23.6 feet

Width of the rectangular wall = 19.2 feet

Surface area of the wall = 23.6 × 19.2

                                        = 453.12 square feet

∵ 200 square feet of the wall is covered by the amount of paint = 1 gallon

∴ 1 square feet of the wall will be covered by the amount of paint = \frac{1}{200} gallons

∴ 453.12 square feet will require the amount of paint = \frac{453.12}{200}

                                                                                         = 2.2656 gallons

Therefore, minimum 3 gallons will be required to paint the wall.
