The perimeter of a rectangle is 86. The length of the rectangle is one more than twice the width. Determine the length and width of the rectangle.

Answers

Answer 1

There are two equation of the system

(1) The perimeter

    2(w + l) = p

    2(w + l) = 86

(2) The length and the width

     2w = l + 2

From the second equation

2w = l + 2

l + 2 = 2w

l = 2w - 2

Subtitute l with 2w - 2 in the first equation to find the width

2(w + l) = 86

2(w + 2w - 2) = 86

2(3w - 2) = 86

6w - 4 = 86

6w = 90

w = 15

Now, find the length by subtituting w with 15

l = 2w - 2

l = 2(15) - 2

l = 30 - 2

l = 28

The dimension of the rectangle

length = 28 cm

width = 15 cm

A bat is sitting in a tree. He leaves the tree and flies up to a speed of 4 meters per second in 8 seconds. How far does he travel?

Answers

Answer:

32 meters

Step-by-step explanation:

4*8=32 and you have to do this because he flies 4 meters per second and in 8 seconds

With the given speed and time a bat travelled 32 meters.

What is the speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given that, A bat is sitting in a tree. He leaves the tree and flies up to a speed of 4 meters per second in 8 seconds.

We know that, speed = Distance/Time

Now, 4 = Distance/8

Distance = 32 meters

Therefore, a bat travelled 32 meters.

Answers

Answer:

AE = CF .

Why?

BD acts as a shape bisector because it cuts the entire rectangle in half from points B and D.

Given that AE is perpendicular to BD, and CF is perpendicular to BD (which we know BD is a bisector), that means that both AE and CF are of equal length inside the rectangle.

Another way to look at it is:

AE = CF because they are technically just vertical angles, shifted and displaced in a weird way; it is a different representation of vertical angles, only distorted. (Don't use this as your answer though, it needs more context. I just want to make it look easier to comprehend.)

I believe that it would be better to use the second scale, or 1ft to 500ft.

Step-by-step explanation:

If you used the first scale(1in to 10ft) then you would have a 75in model, or 6.25ft, this would be to big to display on your desk. If you used the second then your model would be about 1.5in which all though is small it would be better for display.

Answer:

1 inch

Step-by-step explanation:

1 foot = 500 feet

1 inch = 10 feet

^ if you do 12 x 10 it equals 120, which is less than 1 foot = 500.

But, if you want it a big it would be 1 foot = 500.
