The number of bags bought by Javier will be 2.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Javier bought three more bags of Reese's than lollipops and two fewer bags of starburst than lollipops. bags of lollipops cost $3.75 each, bags of Reese's cost $5.50 each, and bags of starburst cost $4.25 each. He spends a total of $48.50.

From the equations and solve them to get the number of lollypops.

R = L+3

L = S - 2

The equation for total cost will be,

3.75L + 5.5R + 4.25S = 48.5

3.75( s - 2) + 5.5( S + 1) + 4.25S

3.75S - 7.5 + 5.50S + 5.5 + 4.25 S = 48.5

13.5S = 48.5 + 2

13.5S = 50.2

S = 4

The number of lollypops will be,

L = S - 2

L = 4 - 2

L = 2

Therefore, the number of bags bought by Javier will be 2.

The physical characteristics of a landscape and can be used in various applications such as habitat modeling and land-use planning.

A metric that measures terrain ruggedness as the variation in three-dimensional orientation of grid cells within a neighborhood is called Terrain Ruggedness Index (TRI). This index is used to quantify the variation in elevation in a specific area. It measures the difference between the elevation of a central grid cell and the average elevation of the surrounding grid cells. The greater the difference, the higher the ruggedness of the terrain. The TRI is a useful measure for understanding the physical characteristics of a landscape and can be used in various applications such as habitat modeling and land-use planning.

Answer:

the third one from the top

Step-by-step explanation:

If point P(2k, k) is equidistant from A(-2, 4) and B (7,-5), the numerical value of k is 3.

The distance formula used in finding the distance between two points is expressed as;

d = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² )

The distance between P(2k, k) and A(-2, 4) is:

d = √((2k - (-2))² + (k - 4)²)

d = √((2k +2)² + (k - 4)²)

The distance between P(2k, k) and B(7, -5) is:

d = √((2k - 7)² + (k - (-5))²)

d = √((2k - 7)² + (k + 5)² )

Since the distances are equal, we can set the two equations for d equal to each other and solve for k.

√((2k +2)² + (k - 4)²) = √((2k - 7)² + (k + 5)² )

Square both sides

(2k +2)² + (k - 4)² = (2k - 7)² + (k + 5)²

(2k +2)² + (k - 4)² = 5k² - 18k + 74

5k² + 20 = 5k² - 18k + 74

Collect like terms

5k² - 5k² + 18k = 74 - 20

18k = 74 - 20

18k = 54

k = 54/18

k = 3

Therefore, the value of k is 3.

Step-by-step explanation:

Answer:

\( \displaystyle 2 {x}^{2} + 4x - 30 = 0\)

Step-by-step explanation:

we are given the zeros and a point where it goes through of a quadratic equation

remember that when the roots are given then the function should be

\( \displaystyle \: y = a(x - x_{1})(x - x_{2}) \)

where a is the leading coefficient and x1 and x2 are the roots

substitute:

\( \displaystyle y = a(x - (3))(x - ( - 5)) \)

simplify:

\( \displaystyle y = a(x - 3)(x + 5) \)

now the given point tells us that when x is 2 y is -14 therefore by using the point we can figure out a

substitute:

\( \displaystyle a(2 - 3)(2 + 5) = - 14\)

simplify parentheses:

\( \displaystyle a( - 1)(7) = - 14\)

simplify multiplication:

\( \displaystyle - 7a = - 14\)

divide both sides by -7:

\( \displaystyle a = 2\)

altogether substitute:

\( \displaystyle y = 2(x - 3)(x + 5) \)

since it want the equation y should be

\( \displaystyle 2(x - 3)(x + 5) = 0\)

recall quadratic equation standard form:

\( \displaystyle {ax}^{2} + bx + c = 0\)

so simplify parentheses:

\( \displaystyle 2( {x}^{2} + 2x - 15 ) = 0\)

distribute:

\( \displaystyle 2 {x}^{2} + 4x - 30 = 0\)

hence,

the equation of the parabola in standard form is 2x²+4x-30=0

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that two sides have lengths 6 and 9, we can analyze the possibilities:

6 + 9 > x

x > 15 - The sum of the two known sides is greater than any possible third side.

6 + x > 9

x > 3 - The length of the unknown side must be greater than the difference between the two known sides.

9 + x > 6

x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.

Based on the analysis, the possible values for the length of the third side are:

A. 7

C. 4

□E. 10

Answer: Bob has to run at a speed of 21.31ft/s to catch the elevator.

Step-by-step explanation:

Let's call Bob's running speed "V".We know that the door is closing at a rate of 1.5ft/s, so the time it takes to close completely is 4.2ft / 1.5ft/s = 2.8 seconds.During this time, Bob has to travel 46ft to reach the elevator. So the time it takes Bob to reach the door is 46ft / V.We also know that the door needs to be at least 0.7ft open when Bob reaches it. So, the time that the door is open when Bob reaches it is 2.8s - (2.8s * 0.7ft / 4.2ft) = 2.8s - 0.6364s = 2.1636s.So, Bob has to cover 46ft in 2.1636s. Solving for V, we get:V = 46ft / 2.1636s = 21.31ft/s (rounded to the nearest hundredth).Therefore, Bob has to run at a speed of 21.31ft/s to catch the elevator.

artin has offered a flat rate of $329, while Jared charges $46 per hour plus $53 for materials. If Jared takes 6 hours to complete the job, his total cost would be the same as Martin's flat rate of $329.

Let's assume the total time taken by Jared to paint the window is 't' hours. Since Jared charges $46 per hour, the labor cost would be $46t. In addition, there is a fixed cost of $53 for materials. Therefore, the total cost for Jared can be expressed as C = 46t + 53.

To find the time at which the cost is the same as Martin's quote of $329, we set C equal to $329 and solve for t:

46t + 53 = 329

Subtracting 53 from both sides gives:

46t = 276

Dividing both sides by 46, we find:

t = 6

So, for the cost to be the same as Martin's quote, Jared would need to take 6 hours. At this time, the cost would be:

C = 46(6) + 53 = 276 + 53 = $329

Therefore, if Jared takes 6 hours to complete the job, his total cost would be the same as Martin's flat rate of $329.

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

It takes 1/5 hours or 12 minutes for 1 centimeter of snow to accumulate in Harper's yard.

We are given that the depth of snow that accumulates in Harper's yard during the first h hours of a snowstorm is given by the equation d = 5h.

To find out how many hours it takes for 1 centimeter of snow to accumulate, we need to find the value of h when the depth of snow d is equal to 1 centimeter.

Substituting d = 1 in the equation d = 5h, we get:

1 = 5h

Dividing both sides by 5, we get:

h = 1/5

In summary, the equation d = 5h gives the depth of snow in centimeters that accumulates in Harper's yard during the first h hours of a snowstorm. To find how many hours it takes for 1 centimeter of snow to accumulate, we substitute d = 1 and solve for h, which gives us h = 1/5 hours or 12 minutes.

We cannot make a fractional number of batches, we would need to round up to 99 batches of muffins and 53 batches of waffles. This would use a total of 253.5 lbs of starter dough,  

To maximize profit, the bakery should find the optimal combination of waffles and muffins to make using their available starter dough. We can start by calculating the maximum number of batches they can make within their 20-hour timeframe.

If it takes 6 minutes to make a half-dozen waffles and 3 minutes to make a half-dozen muffins, then in one hour, they can make 10 batches of waffles and 20 batches of muffins (assuming they work continuously without breaks). Therefore, within 20 hours, they can make a maximum of 200 batches of muffins or 100 batches of waffles.

Next, we can calculate the amount of starter dough required for each batch of waffles or muffins. A half-dozen muffins require 1 lb of the starter dough, so each muffin requires 1/12 lb of dough. On the other hand, 6 waffles require 3/4 lb of dough, so each waffle requires 1/8 lb of dough.

Using this information, we can set up the following system of equations to find the optimal combination of waffles and muffins:

1/12M + 1/8W ≤ 250

M, W ≥ 0

where M is the number of batches of muffins and W is the number of batches of waffles.

The objective function is the profit, which is given by:

P = 2M + 1.5W

To maximize profit, we can use linear programming to solve this problem. However, it is important to note that the solution may not necessarily be an integer value, since we are dealing with fractional amounts of dough.

After solving the system of equations and maximizing the objective function, we find that the optimal combination is approximately 98 batches of muffins and 53 batches of waffles. This would require a total of 223.125 lbs of starter dough.
The bakery would need to either adjust their recipe or obtain additional starter dough to produce the optimal combination of waffles and muffins.

Among the given options, the "Success/Failure Condition" is not a requirement for testing means. The other three options—Randomization, Nearly Normal Condition, and 10% Condition—are necessary conditions to be considered when conducting hypothesis tests on means.

Randomization: Randomization is essential to ensure that the samples being compared are representative of the population and to minimize bias. Random assignment of individuals to treatment groups helps control for confounding variables and increases the validity of the statistical analysis.

Nearly Normal Condition: The Nearly Normal Condition assumes that the data follows a roughly normal distribution within each group being compared. This condition is important because many statistical tests, such as t-tests, rely on the assumption of normality to provide accurate results.

10% Condition: The 10% Condition is relevant when sampling from a finite population. It states that the sample size should be no more than 10% of the population size to ensure that the sampling process does not significantly affect the population distribution.

Success/Failure Condition: The Success/Failure Condition is not directly related to testing means. It is typically associated with tests involving proportions, where the condition specifies that both the number of successes and the number of failures should be at least 10 in each sample or category being compared.

The asymptotes of the original function f(x)=10x and the transformed function g(x) remain the same.

The transformation of reflecting the graph of f(x)=10x about the x-axis followed by shifting it left 12 units creates the new function g(x). The reflection about the x-axis results in the graph of g(x) being upside down compared to the graph of f(x). The shift left 12 units means that the entire graph of g(x) is shifted to the left on the x-axis by 12 units.

However, the transformation does not have any effect on the asymptotes of the function. Asymptotes are vertical or horizontal lines that a function approaches but never touches. They are determined by the behavior of the function as it approaches infinity or negative infinity. Reflecting the graph about the x-axis or shifting it left or right does not change the behavior of the function as it approaches infinity or negative infinity.

21) To simplify 2log6 u - 8log6 v, we use the property of logarithms:

logb xy = logb x + logb y

so, 2log6 u - 8log6 v = log6 (u^2/v^8)

so, 2log6 u - 8log6 v = log6 (u^2/v^8)23)

Using the same property of logarithms, we simplify:

8log3, 12+ 2log3,

5 = log3 (3^8 × 5^2 / 12)

8log3, 12+ 2log3, 5 = log3 (3^8 × 5^2 / 12)25)

To combine the two logarithms, we use the quotient rule of logarithms:

logb x/y = logb x - logb y

So, 2log5 z + log5 x/2 = log5 (z^2 × x^(1/2))

2log5 z + log5 x/2 = log5 (z^2 × x^(1/2))27)

To simplify 6log8 - 30log11, we use the quotient rule of logarithms:

logb x/y = logb x - logb y

So, 6log8 - 30log11 = log8 (8^6 / 11^30)

6log8 - 30log11 = log8 (8^6 / 11^30)22)

Using the property of logarithms, we simplify:

8log5, a + 2log5, b = log5 (a^8b^2)

8log5, a + 2log5, b = log5 (a^8b^2)24)

To simplify 3log4, u - 18log4, v, we use the quotient rule of logarithms:

logb x/y = logb x - logb y

So 3log4, u - 18log, v = log4 (u^3 / v^18)

3log4, u - 18log, v = log4 (u^3 / v^18)26)

To simplify 6log2, u - 24log, v, we use the quotient rule of logarithms:

logb x/y = logb x - logb y

6log2, u - 24log, v = log2 (u^6 / v^24)

6log2, u - 24log, v = log2 (u^6 / v^24)28)

Using the same property of logarithms, we simplify:
