The width of the bookcase is 6 feet and height is 4 feet if the carpenter expects to use 28 feet of lumber to make it.

Let w = the width and h = the height of the bookcase. The width of the lumber you are using is not given.

Also, Let the height is x.

and, the width is 3x -14.

Since, we stated that this equals 28 feet and also that w = 3h - 14, we can insert this into the equation and use it to solve for h:

Now,

The total amount of lumber used to make the bookcase is:

L = 4w + 2h             -------------------------- (1)

Now Putting Width and height in the Equation (1):

⇒ 28 = 4(3h - 14) + 2h

⇒ 28 = 12h - 56 + 2h

⇒ 28 = 14h - 56

⇒ 84 = 14h

⇒ h = 84/14

      = 6 feet

Putting the value of height, h= 6 feet in

w = 3x -14

⇒ w = 3(6) - 14 = 4.

Therefore,

The width is 4 feet and the height is 6 feet.

So the time taken to fill the pool by the slower pipe is 30 hours .

As mentioned about the time in the question stated below.

Let the slower pipe's  time be x and the quicker pipe's time be x/2.

By slower pipe in an hour = 1/x, quicker pipe in an hour = 2/x, and by both = 1/10.

2/x+1/x = 1/10

we have to take reciprocal of the time taken by each pipes.

Elijah has a 41% debt-to-credit ratio. This means that for every $100 of available credit, he has used up $41. This ratio is calculated by dividing total debt by total credit limit.

Elijah's debt-to-credit ratio = Total Debt/Total Credit Limit

= $2,127.50/$5,750.00

= 0.37

= 37%

= 41% (rounded to the nearest whole percent)

Elijah's debt-to-credit ratio is a measure of how much of his available credit he has used. It is calculated by dividing his total debt by his total credit limit. In this case, Elijah currently owes a total of $2,127.50 on his revolving credit account, and his total credit limit is $5,750.00. When we divide his debit of $2,127.50 by his total credit limit of $5,750.00, we get a debt-to-credit ratio of 0.37. This is equivalent to 37%. When we round to the nearest whole percent, we get a debt-to-credit ratio of 41%. This means that for every $100 of available credit, Elijah has used up $41.

Heritability is typically divided into two categories, namely broad sense and narrow sense heritability.

The following formulas are used to calculate heritability in the broad sense:

H² = Vg / Vp

Where,

H² = Heredity

Vg = Genotypic Variance

Vp = Phenotypic Variance

FOR BACK FAT:

Vg = 13.7

Vp = 28.9

H² = Vg / Vp

H² = 13.7 / 28.9

H² = 0.474

FOR BODY LENGTH:

Vg = 27.2

Vp = 49.1

H² = Vg / Vp

H² = 27.2 / 49.1

H² = 0.553

These formulas are used to calculate narrow sense heredity:

H² = Vg / Vp

Where,

H² = Heredity

Vg = Genotypic Variance

Va = Additive Genetic Difference

FOR BACK FAT:

Vp = 28.9

Va = 7.98

H² = Va / Vp

H² = 7.98 / 28.9

H² = 0.276

FOR BODY LENGTH:

Vp = 49.1

Va = 12.4

H² = Va / Vp

H² = 12.4 / 49.1

H² = 0.252

Because back fat has a high narrow sense of heredity and a low broad sense of heritability, it is the best pick. Additionally, heritability in the restricted sense has good breeding value.

The triangles are similar because all the pairs of corresponding angles are congruent.  Therefore, the answer is D.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

In a simpler term, similar triangle have the same shape but the sizes might varies.

Therefore,  Let's check if ΔACB is similar to ΔDCE.

If two triangles have two of their angles equal, the triangles are similar.

Hence,

m∠A = 55 degrees

m∠E = 35 degrees

Therefore, using sum of angles of a triangle is 180 degrees,

∠ACE = ∠DCE =  90 degrees

m∠B = 35 degrees

Therefore,

m∠B = m∠E

∠ACE = ∠DCE =  90 degrees

An equation, also known as an equality, formula, or identity, is a mathematical phrase that states that two or more quantities are equal to one another.

A declaration of the mathematical equivalence of two quantities. The similarity A=B signifies that "A is equal to B."

A mathematical relationship that equalizes one quantity to another is known as an identity (which may initially appear to be different).

A proof in mathematics that one quantity is bigger or smaller than another A>b is used to indicate "A is bigger than B," whereas A<B is used to indicate "A is smaller than B." The symbols A<=B and A>=B stand for "A is less than or equal to" and "A is greater than or equal to B" respectively. The terms "A is much less than B" and "A is much more than B," respectively, are denoted by the symbols A<<B and A>>B.

The number of ways of dealing a five-card hand from a regular 52-card deck, such that the hand contains at least one card in each suit is 2,593,812

What is the combination?

In simple words, combination involves the selection of objects or things out of a larger group where order doesn't matter. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set.

In order to find the number of ways of dealing with a five-card hand from a regular 52-card deck, such that the hand contains at least one card in each suit, we can use the combination formula.

The combination formula is used to find the number of ways to select a certain number of items from a larger group without regard to order.

First, we need to find the total number of ways to select 5 cards from a 52-card deck.

This is given by the combination formula: nCr = n! / (r!(n-r)!)

Where n is the total number of items (52) and r is the number of items to be selected (5).

So, nCr = 52! / (5!47!) = 2, 598, 960

Now we need to subtract the number of ways to select a hand that doesn't contain at least one card of each suit.

We can select 4 cards from one suit and only one card from another suit in 4C1 * 48C4 ways = 448454239/24 = 5148.

Now we can subtract this number from the total number of ways to select 5 cards from a 52-card deck to find the number of ways to select a five-card hand that contains at least one card in each suit:

2598960 - 5148 = 2,593,812

Hence, the number of ways of dealing a five-card hand from a regular 52-card deck, such that the hand contains at least one card in each suit is 2,593,812

Answer:

x= -9.17

Step-by-step explanation:

To solve for x, we can use the information provided about the rectangle to set up an equation. Since opposite sides of a rectangle are congruent (have the same length), we know that MO = NP.

Therefore, we can set up the equation:

-6x + 10 = 65

To solve for x, we can subtract 10 from both sides:

-6x = 55

And then divide both sides by -6:

x = -9.17

A hyperbola is a geometric shape made up of two branches that are symmetric about a center point and asymptotic to two lines called the asymptotes. It is defined by the equation (x^2/a^2) - (y^2/b^2) = 1. It is a type of conic section, similar to a parabola and an ellipse.

If the vertices and foci's of hyperbola have specified coordinates are of the form (0,10) and (0,14)

then

The y-axis serves as the transverse axis.

so

The formula for the equation is:

(y-k)^2/a^2-(x-h)^2/b^2=1

A 5th degree polynomial have five complex roots. This means that the polynomial can be written as the product of five linear or quadratic polynomials.

The general formula to calculate the roots of a 5th degree polynomial is:

[tex]x^5 + ax^4 + bx^3 + cx^2 + dx + e = 0[/tex]

The roots of the polynomial can be found by solving the following equation:

[tex]x^4 + (a - x)x^3 + (b - a x + x^2)x^2 + (c - bx + ax^2 - x^3)x + (d - cx + bx^2 - ax^3 + x^4) = 0[/tex]

To calculate the roots of the polynomial, we need to solve the quartic equation, which can be done by using the quadratic formula. Then, we can use the solutions of the quartic equation to find the roots of the 5th degree polynomial.

For example, if we have the polynomial x^5 + 2x^4 + 3x^3 + 4x^2 + 5x + 6 = 0, then the roots can be calculated as follows:

The convergence set of the given power series is the set of all values of x in the interval (-|x-7|, |x-7|).

In order to determine the convergence set of the given power series, we can use the ratio test.

The ratio test states that if the limit as n goes to infinity of the absolute value of aₙ₊₁ / aₙ is less than 1, then the series converges for all x in the interval (-R, R) where R is the reciprocal of the limit.

The given power series is:

sigma n = 1 to infinity (17/ (n² + 5n))×(x - 7)ⁿ

We can apply the ratio test as follows:

aₙ₊₁ / aₙ = |(17/(n+1)² + 5(n+1))×(x - 7)⁽ⁿ⁺¹⁾ | / |(17/ (n² + 5n))×(x - 7)ⁿ|

aₙ₊₁ / aₙ = |(17/(n+1)² + 5(n+1))/(n² + 5n) × |(x - 7)|⁽ⁿ⁺¹⁾ | / |(x - 7)|ⁿ

As we can see the limit as n goes to infinity of the absolute value of

aₙ₊₁ / aₙ = |(x - 7)|

Let R = |x - 7|, therefore, the series converges for all x in the interval (-R, R)

So the series converges for all values of x in the interval (-|x-7|, |x-7|).
