The length of a rectangle is 7 more than the width the area is 744 square centimeters find length and width of rectangle
andrezito [222]

Answer:

l=31\ cm\\\\w=24\ cm

Step-by-step explanation:

The formula that is used to calculate the area of a rectangle is:

A=lw

Where "l" is the lenght and "w" is the width.

You know that the area of that rectangle is:

A=744\ cm^2

And, according to the exercise, its lenght is 7 more than its width; then:

l=w+7

Then, you can make the corresponding substitution into the formula A=lw:

 744=(w+7)w

Simplify:

744=w^2+7w\\\\w^2+7w-744=0

Factor the equation. Find two numbers whose sum is 7 and whose product is -744. These are 31 and -24.

Then, you get:

(w-24)(w+31)=0\\\\w_1=24\\\\w_2=-31

The width of the rectangle is the positive value:

w=24\ cm

Then, the lenght is:

l=24+7\\\\l=31\ cm

Determine the value of cos 79º 15' (cosine of 79 degrees, and 15 minutes). In this case, minutes are 1/60 of a degree.
yKpoI14uk [10]

Answer:

A. 0.186524036

Step-by-step explanation:

Cosine 79° 15'

But, 1° = 60'

Thus; 15' = 15/60 = 0.25°

Therefore;

cos 79° 15' = cos 79.25°

Cos 79.25° = 0.186524036

                  = 0.186524036

A walker has travelled 9 km along a trail. If he has completed 80% of the trail, how much further does he still have to go?
Anit [1.1K]

Answer:

2.25 km to go

Step-by-step explanation:

In order to get this answer, you have to figure out how many km 10% is, 0.1125. Then multiply that by the remaining 20% because he already finished 80% of the trail. So, 0.1125 x 20 = 2.25.

Hope this helps! :)
