Mr. Malone can heat his house in the winter by burning three cords of wood, by sing natural gas, or by combination of the two. H

Xelga [282]

Answer:

The linear equation can be written as

$3x+y-(x+y)=$600$

Step-by-step explanation:

Given that "Mr. Malone can heat his house in the winter by burning three cords of wood, by sing natural gas, or by combination of the two"

And his heating budget for the winter is $600

To find a linear equation that describes the problem:

Let the cords of wood be x and let sing natural gas be y

So that the combination of the cords of wood and sing natural gas is x+y

Now the linear equation can be written as

$3x+y-(x+y)=$600$

My circumference is 20 cm what is my diameter and radius?

Musya8 [376]

Answer:

The diameter of the circle would be: 6.4 cm. rounded or 6.36619772 cm.

The radius of the circle would be: 3.2 cm. rounded or 3.18309886 cm.

Step-by-step explanation:

<h3>The diameter can be solved using: D = $\frac{C}{\pi }$ </h3>

So, the first step would be : D = $\frac{20}{\pi }$

Then : D = 20 ÷ $\pi$

Finally, the answer will be : 6.36619772 cm. or 6.4 cm.

<h3>The Radius can be Solved using: r = $\frac{c}{2\pi }$ </h3>

The first step would be : r = $\frac{20}{2\pi }$

Then : 20 ÷ 6.2831853071796 (2 $\pi$ )

Finally, the answer will be : 3.18309886 cm. or 3.2 cm.
