Answer:
width: 40 unitslength: 51 unitsarea: 2040 square unitsStep-by-step explanation:
Let w represent the width of the rectangle. Then w+11 is the length. The perimeter is given by ...
P = 2(L +W)
182 = 2((w+11) +w)
182 = 4w +22 . . . . . simplify
160 = 4w . . . . . . . . . subtract 22
40 = w . . . . . . . . . . . divide by 4
40 +11 = length = 51 . . . . determine length
The dimensions of the rectangle are 40 × 51 units.
__
The area of the rectangle is ...
A = LW
A = (51)(40) = 2040 . . . . square units
The area is 2040 square units.

Additional comment
The perimeter of a rectangle is double the sum of length and width, so that sum is 182/2 = 91 units. Now, this is a "sum and difference" problem, where the sum of length and width is 91, and the difference is 11. The solutions to such a problem are half the sum and half the difference of these numbers. Above, we found the smaller dimension (width) first: (91-11)/2 = 40. We could have found the length as (91+11)/2 = 51. The knowledge of the general solution to "sum and difference" problems often lets you work them with mental arithmetic.

An airplane is flying with a constant altitude at a speed of 450 mph in a direction 10° north of west directly towards its final destination. The airplane then encounters wind blowing at a steady 34 mph in a direction 85° north of east. If the pilot does not correct his course after encountering the wind, at what speed and in what direction (counterclockwise from east) will the plane be traveling? Speed: _____mph Direction:______ °
Answer:
your answer is gonna be 579 miles that would be your answer
The ground speed will be 454.2 mph in north east.
What is a vector?The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
Given that airplane is flying with a constant altitude at a speed of 450 mph in a direction 10° north of west directly towards its final destination.
The airplane then encounters wind blowing at a steady 34 mph in a direction 85° north of east.
The component of an airplane will be
x =450 sin 10
x = -244.8
y = 450 cos 10
x = -377.5
The component of wind will be
x =34sin 85
x = -5.98
y = 34 cos 85
x = -33.4
Then the ground speed will be 454.2 mph in north east.

A plane traveled 588 miles each way to Athens and back. The trip there was with the wind. It
took 7 hours. The trip back was into the wind. The trip back took 14 hours. Find the speed of
the plane in still air and the speed of the wind.
Answer:
The wind speed is 21 miles per hour, and the speed of the plane in still air is 63 miles per hour.
Step-by-step explanation:
Since a plane traveled 588 miles each way to Athens and back, and the trip there was with the wind and took 7 hours, while the trip back was into the wind and took 14 hours, to find the speed of the plane in still air and the speed of the wind, the following calculations must be performed:
Downwind travel = 588/7 = 84 miles per hour
Headwind travel = 588/14 = 42 miles per hour
84 - 42 = 42/2 = 21
84 - 21 = 63
Therefore, the wind speed is 21 miles per hour, and the speed of the plane in still air is 63 miles per hour.

Answer:
History
Dubai’s golden era began in 1966. Oil was found at the offshore Fateh field, which is also known as the Fath of Oil. At that time, even the brightest brains could not begin to imagine Dubai relishing in the opportunities that are present in Dubai today. Oil became the gateway to a brand new world. Although it wasn’t a gateway for the locals to connect outside of Dubai, it was a gateway for foreigners to come into Dubai.
Merely a half a century ago, all of these big edifices, businesses, and residential developments were not even thought to exist. It may be hard to believe, but the village was indeed replaced by a thriving city. In 1883, Dubai’s current leaders took control, and ruled the village. Back then, the most critical financial source was limited to pearl-fishing.
Step by step, the whole city was replenished by new buildings, modern edifices and high-end apartments. The number of residents and which is of more importance, tourists is still increasing, and thus the hotels, townhouses, penthouses and apartments for rent are of high demand. Today, when you look at the exceptional oasis created by Sheik Mohammed bin al-Maktoum, along with the crown prince, it is hard to believe that this was once a village with a limited source of finances.

How many yards of fence does Raul need to
fence in a garden that is 12ą yards long and 9
yards wide?
Don’t tell me to “download the answer” that’s bs
Answer:
Raul needs 42 yards of fence.
Step-by-step explanation:
Perimeter of a rectangle:
The perimeter of a rectangle of length l and width w is given by:
P = 2(l + w)
In this question:
The fence is rectangular.
12 yards long means that l = 12.
9 yards wide means that w = 9.
Perimeter:
P = 2(12 + 9) = 2(21) = 42
Raul needs 42 yards of fence.
