A farmer builds a rectangular pen with a perimeter of 116 feet. If the length is 5 feet more than the width, what is the width?

1 answer:

3 0

The formula for the perimeter of a rectangle is:
A=2l+2w.
We know the area is 116, so we can plug that in for A. Now, we cant solve the equation yet because it still has two variables. Since we know the length is 5 feet greater than the width, we can rewrite l in terms of w. So here is what our new equation will look like:
116=2(w+5)+2w
Now lets solve:
116=2w+10+2w
106=4w
w=26.5 ft.
The width is 26.5 ft.

How many terms are there in the following expression? x - 5 + 16x + 4 - 2x - 3

k0ka [10]

Answer:

Two terms

Step-by-step explanation:

First, we have to simplify reducing the number of terms, since there are like terms

x-5+16x+4-2x-3

Eventually, you'll get 15x-4, thus there are two terms.

Please correct me if I'm incorrect, and I'll change the answer, but I hope I helped :)

Find, to the nearest tenth, the area of the region that is inside the square and outside the circle. the diameter of the circle

Doss [256]

Answer:

Option $42.1\ in^{2}$

Step-by-step explanation:

we know that

The area of the region that is inside the square and outside the circle is equal to the area of the square minus the area of the circle

see the attached figure to better understand the problem

Step 1

<u>Find the area of the square</u>

Remember that

The area of the square is

$A=b^{2}$

where

b is the length side of the square

we have

$b=14\ in$

substitute

$A=14^{2}=196\ in^{2}$

Step 2

<u>Find the area of the circle</u>

Remember that

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=14/2=7\ in$

substitute

$A=\pi(7^{2})=153.9\ in^{2}$

Step 3

<u>Find the area of the region</u>

$196\ in^{2}-153.9\ in^{2}=42.1\ in^{2}$

<h3>Answers: </h3><h3>A) satellites</h3><h3>D) Weather balloons</h3><h3>E) Automated weather stations</h3>

=====================================================

Explanation:

Satellites are used to measure things like the formation of storms and predicting where they will go. They provide a big picture of the climate as a whole, and they're useful for studying climate patterns.

Weather balloons are used to measure humidity, wind speed, temperature and pressure in the atmosphere. They are useful because they are very inexpensive compared to satellites, and can be made quicker.

Automated weather stations are locations where much of the same things are measured with weather balloons, though on the ground rather high in the air. In addition, weather stations will likely have a rain gauge to measure how much rain has fallen in a certain area.
