Answer:

First find the area 72*63

A=4536

Then find the area 12*12

A=144

Then divide 4536/144

You would need 31.5 12 by 12in covers to decorate the rectangular region

As for the 6 by 6

You would need 126 album covers

As for the 9 by 9

You would need 51 covers

And as for the 15 by 15

You would need 20.6 covers

Find the measure or angle xyz
blagie [28]

Answer:

The answer to your question is: 85°

Step-by-step explanation:

Data

m∠ xyz = 2m∠x - 9

m∠w = 38°

Process

∠x = (∠xyz + 9) / 2

∠ y = 180 - ∠xyz

∠w + ∠y + ∠x = 180

                             

Substitution              38 + (180 - ∠xyz) +   (∠xyz + 9) / 2 = 180

                                 76 + 360 - 2∠xyz + ∠xyz + 9 = 360

Simplify

                                 85 - 2∠xyz + ∠xyz = 0

                                  85 = ∠ xyz

An express train travels 80km/h from Ironton to Wildwood. A local train, traveling at 48km/h, takes 2 hours longer for the same
masha68 [24]

Answer:

They are 240 kilometers apart.

Step-by-step explanation:

This question can be solved using the following relation:

v = \frac{d}{t}

In which v is the velocity, d is the distance and t is the time.

An express train travels 80km/h from Ironton to Wildwood.

Here we have v = 80, t = x. So

v = \frac{d}{t}

80 = \frac{d}{x}

d = 80x

A local train, traveling at 48km/h, takes 2 hours longer for the same trip.

This means that when v = 48, t = x + 2[tex]. So[tex]v = \frac{d}{t}

48 = \frac{d}{x+2}

Since d = 80x

48 = \frac{80x}{x+2}

Applying cross multiplication

80x = 48(x + 2)

80x = 48x + 96

32x = 96

x = \frac{96}{32}

x = 3

So the distance is:

d = 80x = 80*3 = 240

They are 240 kilometers apart.
