A Concrete Block Has A Volume Of 48 Cubic Meters And The Dimensions Show. Find The Value Of X.

Answers

Answer 1
the value of x is 2.
substitute 2 in place of x on each length of the block
3(2) + 2 = 8m
2(2) - 1 = 3m
2m
multiply the three lengths by each other (length x width x height) (l x w x h)
8 x 3 = 24
24 x 2 = 48m

What is the length of the hypotenuse? If necessary, round to the nearest tenth.

Answers

Answer:

The length of the hypotenuse is 6.4 yards.

Step-by-step explanation:

We can use the Pythagorean Theorem to evaluate the hypotenuse.

The formula for the Pythagorean Theorem is

[tex]a^2+b^2=c^2[/tex]

Where [tex]a[/tex] and [tex]b[/tex] are the legs of the triangle; and [tex]c[/tex] is the hypotenuse.

We are given the values of both legs.

[tex]a=4\\b=5[/tex]

Inserting these values into the equation gives us

[tex]4^2+5^2=c^2[/tex]

Lets solve for [tex]c[/tex].

Evaluate [tex]4^2[/tex].

[tex]16+5^2=c^2[/tex]

Evaluate [tex]5^2[/tex].

[tex]16+25=c^2[/tex]

Add [tex]16[/tex] and [tex]25[/tex].

[tex]41=c^2[/tex]

Take the square root of both sides to eliminate the exponent.

is it possible to have a connected graph with six (6) vertices of degrees 1, 1, 2, 2, 2, and 3? if possible, why possible explain. if not possible, why not possible explain.

Answers

No, it is not possible to have a connected graph with six vertices of degrees 1, 1, 2, 2, 2, and 3.

As we know that the sum of the degrees of the vertices in a connected graph must be equal to twice the number of edges.

So, in this case, the sum of the degrees must be equal to 2 * K, where K is the number of edges in the graph.

Since the degrees of the vertices are 1, 1, 2, 2, 2, and 3,

the sum of the degrees is 1 + 1 + 2 + 2 + 2 + 3 = 11.

The number of edges must be K = 11 / 2 = 5.5,

which is not possible as the number of edges must be a positive integer.

Therefore, it is not possible to have a connected graph with six vertices of degrees 1, 1, 2, 2, 2, and 3.

What are parallel lines?

Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline. No matter how far we extend a parallel line, it will never meet another parallel line.

The slope of two parallel lines are equal.

The equation of the given line is:

y = x + 6

Final answer:

To calculate the total amount of apples Alan has bought, we simply apply the concept of Algebraic Expressions and add the pounds of red apples (which is 4) to the pounds of green apples (which is represented by g). This can be represented in a mathematical expression as 4 + g.

Explanation:

Alan bought 4 pounds of red apples and g pounds of green apples. To find out how many pounds of apples he bought in total, we need to add the quantities together.

three married couples have bought 6 seats in the same row for a concert. in how many different ways can they be seated

Answers

The 3 couples can be seated in 20 ways.

Permutations Calculations

The answer I provided uses the concept of permutations. In permutation, we calculate the number of arrangements or ways in which a set of elements can be arranged.

In this case, the question is asking for the number of ways in which 6 individuals (3 married couples) can be seated in a row. To find the number of arrangements, we can use the formula for permutations of multiples:

P(n, k) = n! / (n-k)!

Where n is the number of items to arrange and k is the number of identical items. In this case, n = 6 (number of individuals) and k = 3 (number of married couples).

However, we need to also account for the fact that within each married couple, the two individuals can be seated in either order. Hence, we need to divide the result by 2! for each couple, giving us the formula:

P(6, 3) / (2! * 2! * 2!) = 6! / (3! * 3!) = 20

So there are 20 different ways in which the 3 married couples can be seated in a row.
