The direct variation equation that relate the amount of concrete needed and the number of posts is y = 5/4x

An equation is the equality between two algebraic expressions, which have at least one unknown or variable.

To solve this problem, we have to state the equation using the information of the problem:

Information about the problem:

Calculating the number of concrete according to the number of posts we have:

6 1/4

= [(4*6)+1] / 4

= (24 + 1) / 4

= 25/4

Number of concrete per post = 25/4 bags / 5 post

Number of concrete per post = 5/4 bags / post

Writing the equation according to the information gave, we have:

y = 5/4x

Lets called (y) the amount of concrete needed and (x) the number of posts

The "y" variable is the dependent variable, it will change according to the number of posts x (x).

The "x" variable is the independent variable, because it doesn't depend on any other value, just the the number of posts.

Step-by-step explanation:

There is no Tuesday in the set to the right, so the set to the left is not a subset of the set to the right.

Answer: B. ⊄

Answer:

Alright so the Diameter ratio of cylinder a & b = 1:2 and Length (height) ratio of cylinder a & b = 3:1

We have to find the volume ratio of cylinder a & b.

Let the diameter of cylinder a = 1r and,the diameter of cylinder b = 2r, the length of cylinder a = 3h, and,the length of cylinder b = h

(h & r are assumed as variables)

So,

The radius of cylinder a = 1r/2

The radius of cylinder b = 2r/2 = r

So,

The volume of cylinder a = π × (1r/2)² × 3h = π × 1r²/4 × 3h = 3πr²h/4

The volume of cylinder b = π × (r)² × h = πr²h

Ratio of volume = 3πr²h/4 : πr²h = 3πr²h/4 × 1/πr²h = 3/4 = 3:4

So,the ratio of their volume is 3:4

Answer:

A(n) = 1500 * (1 + 0.0367)^n

Step-by-step explanation:

Given that Ted's account has $1535.25 after 1 year, we can use that value to write an explicit expression for the function A(n).

The amount in the account after n years is given by the formula:

A(n) = A(0) * (1 + r)^n

where A(0) is the initial amount in the account and r is the interest rate.

Since A(1) = $1535.25 and A(0) = $1500, we can substitute these values into the formula:

1535.25 = 1500 * (1 + r)^1

Solving for r:

r = (1535.25/1500) - 1 = 0.0367

So, the interest rate is 3.67% and the explicit expression for the function A(n) is:

A(n) = 1500 * (1 + 0.0367)^n

The factorization of 3x² - 6x - 24 will be (x + 8)(x - 10).

The equation is a polynomial with leading coefficient 3, the equations os in standard form, where the leading coefficient is positive and the terms are ordered from highest degree to lowest degree.

To solve thw equation goes thus:

3x² - 6x - 24

Divide through by 3

x² - 2x - 80

x² - 10x + 8x - 80

x(x - 10) + 8(x - 10)

(x + 8)(x - 10)

The value will be (x + 8)(x - 10).

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables." from Wolfram Math World: linear.

If the automaker facility operates for five days out of the week and 60 trucks are produced each week, then the number of trucks assembled per day is:

= daily 12 trucks

The number of trucks assembled every hour at the automaker's plant, which runs for 12 hours in a half-day, is:

The Probability that 4 games will be played in total and determine the likelihood that b will win the game are 2[(p³(1-p) + p(1-p)³] and p² / [p² + (1-p)²]

Given that,

A and B engage in a number of games. A and B each win a game with a probability of p and 1-p, respectively. They come to an end when one player has two more victories overall than the other player. The contest is decided by whoever player has accrued the most victories overall.

To find : The Probability that 4 games will be played in total and determine the likelihood that b will win the game.

Determine first which exact order of wins causes games.

The first game is won by A: B triumphs in game two ( if A wins again, Awon and the game is over)A or B might win the following two games to give themselves a two-game lead equivalently in the scenario if B triumphs in game one.

The ordering can be ABAA, ABBB, BAAA, or BABB.

P(4 games  precisely) = P(ABAA) + P(ABBB) + P(BAAA)+ P(BABB)

P(4 games  precisely)  = 2[(p³(1-p) + p(1-p)³]

The measures of the two angles is 40° and 50° list your angles from smallest to largest is 40° to 50°.

When two straight lines or rays meet at the same place, an angle is formed. The vertex of an angle is the location at which all points meet. Angle is derived from the Latin word angulus, which means "corner." In the Early Middle Ages, England was home to a particular cultural group known as the Anglo-Saxons. They were the offspring of settlers who came to Britain from continental Europe in the fifth century. However, the ethnogenesis of the Anglo-Saxons occurred in Britain; they did not merely accept a foreign identity.

Let the angle be X

Let the complimentary angle be Y

X + 60 = 2Y … equation 1

Y + X= 90

(complimentary angles always equal to 90°)

Y = 90 - X …. equation 2

Substitute equation 2 into equation 1

[tex]X + 60 = 2 x (90 - X)\\X + 60 = 180 - 2X\\X + 2X = 180 - 60\\3X = 120\\X = 40[/tex] … equation 3

Therefore, the angle (X) equals 40°

To calculate Y, substitute equation 3 into equation 2.

[tex]Y = 90 - 40\\Y = 50°[/tex]

Therefore the complimentary angle is 50°

To check if the answer is correct

The angle (40) plus 60 is 100

The complementary angle (50) divided by two equals 100.

The gallons of 16%salt solution required to obtained 20% of salt solution is equal to 5 gallons.

Let us consider 'x' be the salt solution of 16%

And 'y' be the salt solution with 25%

Total gallons of salt used is equal to 4 gallons

Required salt solution = 20%

Equation formed as per given information :

16% of x + 25% of 4 = 20% of ( 4 + x )

⇒ ( 16 / 100 ) × x + ( 25 / 100 ) × 4 = ( 20 / 100 ) × ( 4 + x )

⇒ 0.16x + 1 = 0.8 + 0.20x  

⇒ 0.20x - 0.16x  =  1 - 0.8

⇒ 0.04x = 0.2

⇒ x  = 0.2 / 0.04

⇒ x =  20 / 4

A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.

Each line of the polygonal circuit's segments are referred to as its edges or sides.

The figure has six sides so it is a hexagon and we know the sum of all the interior angles in a hexagon is 720°.

Therefore, 142° + 169° + 59° + 131° + 127° + x = 720°.

x + 628° = 720°.

The required probability is P(G|F) = 0.5.

Renate's chance of winning a Green Card, given that she was a finalist, can be calculated as follows:

P(G|F) = P(G and F) / P(F)

Where P(G and F) is the probability of both Renate winning a Green Card and Renate being a finalist, and P(F) is the probability of Renate being a finalist.

Since Renate was one of 110,000 finalists, P(F) = 110,000 / 6.5 million = 0.016923076923076924

Out of the 110,000 finalists, 55,000 won a Green Card, so P(G and F) = 55,000 / 6.5 million = 0.008461538461538462

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

We have to given that;

You buy 10 vegetarian pizzas and pay with $100.

Here, The cost of the three vegetarian pizzas is 25 dollars and 50 cents.

Hence, The cost of the three vegetarian pizzas = $25.5

Thus, The cost of the 10 vegetarian pizzas = $25.5 × 10 / 3

2. Then you multiply the numbers across from each other. (both numerators and denominators)

So, it would then be [tex]\frac{-45}{1-}[/tex]

(remember, when multiplying or dividing negatives and positives, a negative to a positive (vice versa) will always come out to be a negative, and a positive to a positive or negative to a negative, it'll always be a positive)
