Proportionately, if Hayden uses 4 cups of flour and 5 cups of sugar to make cupcakes, he will eat 20 cupcakes.

Proportion refers to the relative size or ratio of one value compared to another quantity.

Proportions are represented as fractional values with decimals, percentages, or fractions.

The quantity of flour for 1 cupcake = 1/5 cups

The quantity of sugar for 1 cupcake = 1/4 cups

The quantity of flour Hayden uses = 4 cups

The number of cupcakes from 4 cups = 20 (4 ÷ 1/5)

The quantity of sugar Hayden uses = 5 cups

The number of cupcakes from 5 cups of sugar = 20 (5 ÷ 1/4)

Thus, according to the proportion of cupcake ingredients to the available quantities of ingredients, Hayden will make and eat 20 cupcakes.

Answer: 3 , 4 and 5 are correct options

Step-by-step explanation:

The event with a sample space of S = {A, B} is (d) choosing a tile from a pair of tiles, one with the letter A and one with the letter B.

From the question, we have the following parameters that can be used in our computation:

Sample space of S = {A, B}

In probability, the sample space is the set of all possible outcomes of a random event.

In the case of choosing a tile from a pair of tiles, one with the letter A and one with the letter B, there are only two possible outcomes: A or B.

Therefore, the sample space S is {A, B}.

In contrast, for the other events listed:

In each of these events, there are more than two possible outcomes, so the sample space is a set with more than two elements.

From the properties of similarity, the value of x is 24.

Euclidean geometry states that two objects are comparable if they have the same shape or the same shape as each other's mirror image. More specifically, by uniformly scaling (enlarging or decreasing), maybe with additional translation, rotation, and reflection, one can be created from the other. This indicates that one object may be properly aligned with the other object by rescaling, moving, and reflecting it. When two things are comparable to one another, one is consistent with the outcome of a specific uniform scaling of the other.

By comparing corresponding sides of the shapes, we get that

6/9 = 14/21 = 2/3

So that,

16/x =2/3

multiply both sides by 3/2 we get,

(16/x)*(3/2) = 1

multiply both sides by x we get,

16*3/2 = x

⇒ x = 48/2

⇒ x = 24

Answer:Let's call the two numbers x and y. We know that:

xy = 72

x + y = -38

We can use the first equation to solve for one of the variables in terms of the other:

x = 72/y

Then, we can substitute this expression into the second equation:

72/y + y = -38

y^2 + 72 = 38y

y^2 - 38y + 72 = 0

This is a quadratic equation that can be solved using the quadratic formula:

y = (-b ± √(b^2 - 4ac)) / 2a

where a = 1, b = -38, c = 72.

Plugging in these values, we get:

y = (38 ± √(38^2 - 4(1)(72))) / 2(1)

y = (38 ± √(1444)) / 2

y = (38 ± 38) / 2

So, we have two solutions for y:

y = 38 / 2 = 19

y = -38 / 2 = -19

With either of these values for y, we can use the first equation to solve for x:

x = 72/y = 72/19 = 3.8

or

x = 72/-19 = -3.8

So, the two numbers whose product is 72 and whose sum is -38 are x = 3.8 and y = 19, or x = -3.8 and y = -19.

Step-by-step explanation:

Let's call the two numbers x and y. We know that:

The equation of the horizontal asymptote of f(x) is given as follows:

x = 5/4.

The rational function f(x) in the context of this problem is defined as follows:

f(x) = (-4x² + 54x - 47)/(4x - 5).

The horizontal asymptote of a function happens at a value of x which is outside the function's domain.

For a rational function, the denominator cannot be zero, hence the value of x that represents the horizontal asymptote of f(x) is obtained as follows:

4x - 5 = 0

4x = 5

x = 5/4.

It took Bailey 45 days to paint the house and Andrew 11.25 days to paint the house.

A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Given that, Andrew can paint the neighbor's house 4 times as fast as Bailey. Andrew and Bailey worked together, it took them 5 days.

Let the time it took Bailey to paint the house be x days, and the time it took Andrew to paint the same house be y. Then,

Establishing the system of equation,

1/x + 1/y = 1/9. . . (1)

x = 4y. . . (2)

Putting (2) into (1) gives,

1/4y + 1/y = 1/9

If Jane took 30 min to drive her boat upstream to water-ski at her favorite spot. her boat speed in still water is;3 km/h.

Let's x represent the  Jane's boat speed in still water

Upstream, her speed was x - 2 km/h.

Downstream, her speed was x + 2 km/h.

Let's d represent the distance between the start and end point

Let the  time it takes to cover d at a speed of x - 2 km/h=  30 min.

Let the  time it takes to cover d at a speed of x + 2 km/h=  10 min.

So we have:

d / (x - 2) = 30 min and

d / (x + 2) = 10 min.

Multiplying both sides of each equation

d * x - 2d = 30 * (x - 2)

d * x + 2d = 10 * (x + 2).

Adding the two equations and solve for x

2d * x = 40 * x + 20

20 * x = 40 * x + 20

20 * x = 60 * x

x= 3 km/h

Step-by-step explanation:

Regarding shopping for a new card, it would depend on the terms and conditions of the new card, including the annual interest rate and any fees. Rachel should compare the options available and weigh the benefits and drawbacks of each before making a decision.

The length of time it will take Rachel to pay off her credit card balance can be calculated by dividing the outstanding balance by the monthly payment amount and then adding the number of months needed to pay off the balance.

Balance = $8,281

Monthly payment = $250

Annual interest rate = 16%

To calculate the length of time it will take to pay off the balance, we would first need to calculate the monthly interest rate, which can be done by dividing the annual interest rate by 12:

Monthly interest rate = 16% / 12 = 1.33%

Next, we can calculate the monthly payment amount, including the interest:

Monthly payment amount = $250 + ($8,281 * 1.33%)

By continually subtracting the monthly payment amount from the balance and adding the monthly interest, we can determine the length of time it will take to pay off the balance.

We know from the problem that l = 3w - 5. We also know the formula for area is A = w * l. Therefore, the area of the rectangle is A = w * (3w - 5). We can then set this equation equal to 50 as the question states and solve for w.

[tex]50 = w * (3w-5)[/tex]

Expand the multiplication

[tex]50 = 3w^{2}- 5w[/tex]

Subtract 50 from both sides.

[tex]0 = 3w^{2} - 5w - 50[/tex]

We now have a quadratic equation and can solve it using the quadratic formula to find w. We find that the solutions to the equation are 5 and -3.3. We know that the width can't be negative, so the width must be 5.

Finally, we can plug this solution into the length formula we found earlier to solve for length.

[tex]l = 3w - 5[/tex]

Plug in the solution to w.

[tex]l = 3(5) - 5[/tex]

Multiply 3 and 5.

[tex]l = 15-5[/tex]

Subtract 5

[tex]l = 10[/tex]

Therefore the width is 5 and the length is 10.

The annual interest you would earn on each bond depends on the bond's coupon rate, which can be calculated by dividing the bond's current yield (Column 2) by 100. For Bond A and C, the coupon rate would be 7.5%, and for Bond X and Y, it would be 8.4%. The annual interest you would earn on each bond would be the coupon rate multiplied by the bond's face value (Column 1). For Bond A and C, the annual interest would be 7.5% * $15 = $1.125, and for Bond X and Y, it would be 8.4% * $15 = $1.26.

The equation of the line that runs through the point (0,-1) and (1,2) in slope-intercept form is y = 3x - 1.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

From the diagram, the line runs through the point (0,-1) and (1,2).

First, we determine the slope of the line

Slope m = change in y / change in x

Slope m = (2 - (-1)) / (1 - 0)

Slope m = (2 + 1) / (1 - 0)

Slope m = 3/1

Slope m = 3

Next, plug the slope m = 3 and point (0,-1) into the point slope formula.

y - y₁ = m( x - x₁ )

y - (-1) = 3( x - 0 )

y + 1 = 3x - 0

y + 1 = 3x

Subtract 1 from both sides

y + 1 - 1 = 3x -1

y = 3x - 1

Therefore, the equation of the line is y = 3x - 1.
