Answer: 1 .Thus for a graph to have an Euler circuit, all vertices must have even degree. The converse is also true: if all the vertices of a graph have even degree, then the graph has an Euler circuit, and if there are exactly two vertices with odd degree, the graph has an Euler path.

2. A graph has an Euler circuit if and only if the degree of every vertex is even. A graph has an Euler path if and only if there are at most two vertices with odd degree.

This handy application of LCMs is used by astronomers. All the planets in our solar system revolve around the sun. The planets o

TiliK225 [7]

To find number of years we take LCM of planets revolution times.

Planet's revolution times are given in the chart

Solar System Planet Revolution Time

Earth 1 year

Mars 2 years

Jupiter 12 years

Saturn 30 years

Uranus 84 years

Neptune 165 years

We take LCM of 1,2,12,30,84 and 165

Prime factorization of 2 = 2

Prime factorization of 12 = 2^2 * 3

Prime factorization of 30 = 2 * 3* 5

Prime factorization of 84 = 2^2 * 3 * 7

Prime factorization of 165 = 3*5*11

We take set of prime factors that has highest exponent,

So LCM = 2^2 * 3 * 5 * 7 * 11 = 4620

Therefore it will take 4620 years.

Explain why 15.839 rounded to the nearest tenth is 15.8

makvit [3.9K]

Step-by-step explanation:

A tenth is 0.1

To round of to the nearest tenth means to round it of to 1 decimal place.

Now, look at the number after the tenth place with is 0.03 or simply 3.

If the digit is 0-4, you round the whole number down.

Hence, 15.839 is 15.8 to the nearest tenth digit.

If the tenth digit is 5-9 such as 15.85 or 15.87, you round the number up, to give 15.9

Alex is building a rectangle fence around his yard. the total perimeter of the fence is 68 feet and the area of his yard is 240

Alisiya [41]

Let's call the length of the rectangular fence $l$ and the width of the rectangular fence $w$ .

Based on the information in the problem, we can make two equations, based on the formulas for perimeter and area:

$A = lw$

$P = 2l + 2w$

Now, let's substitute in the values we are given in the problem:

$240 = lw$

$68 = 2l + 2w$

Now, let's solve the system using substitution.

$240 = lw \Rightarrow \dfrac{240}{w} = l$

Solve for $l$ from the first equation

$68 = 2\Bigg( \dfrac{240}{w} \Bigg) + 2w$

Substitute this value into the second equation

$68 = \dfrac{480}{w} + 2w$

Simplify

$68w = 480 + 2w^2$

Multiply both sides of the equation by $w$

$2w^2 - 68w + 480 = 0$

Subtract $68w$ from both sides of the equation

$(2w - 48)(w - 10) = 0$

Factor

$2w - 48 = 0$ and $w - 10 = 0$

Use the Zero Product Property and solve both factors

$2w - 48 = 0 \Rightarrow 2w = 48 \Rightarrow w = 24$

$w - 10 = 0 \Rightarrow w = 10$

We are given two possible lengths. However, the funny thing is that both produce the same dimensions: 24 ft by 10 ft:

$w = 24 \Rightarrow 240 = l(24) \Rightarrow l = 10$

$w = 10 \Rightarrow 240 = l(10) \Rightarrow l = 24$

Thus, our answer is Choice C, or 10 feet by 24 feet.
