The cost of the baker's shelf is $1,448.94
How to calculate the cost of the baker's shelf ?
The length of the bakery is 12 meters
The width of the bakery is 19 meters
The wooden shelf costs £23.37 per meter
The cost can be calculated as follows
2(12+19) × 23.37
= 2(31) × 23.37
= 62 × 23.37
= 1,448.94

Clearly indicate what the variable represents.
Answer:
5 hoursStep-by-step explanation:
Let the hours of actual work be x and total charge be y.
The greenhouseTotal amount of charge is:
y = 11x + 20Garden prosTotal amount of charge is:
y = 15xSince y is same for both companies, set the equation and solve for x:

The rate unit of the cost of the juice bought by Megan is $1.28 per quart.
What is defined as the unitary method?The unitary method is a methodology that involves determining the value of a single unit and then calculating the value of the requisite number of units based on that value.The unitary method's formula is to obtain the price of a single unit and afterwards multiply that value by the number of components to get the required value.For the given question;
The price of 2-quart bottle of juice bought by Megan = $2.56.
For calculating the price of 1 bottle, simply divide the total cost by number of bottles.
Price of a single quart bottle = $2.56/2.
Price of a single quart bottle = $1.28 per quart.
Thus, the price of single quart bottle of juice is 1.28 per quart.

The catering cost was determined if the cost per person is R225,00. then the cost of 50 people is equal to = 1,125,000 R.
The catering cost was determined if the cost per person is R 225,00.
The cost per person = 225,00 R
To calculate the cost per unit, add all of your fixed costs and all of your variable costs together and then divide this by the total amount of units you produced during that time period.
Let us assume,
Suppose you can find the cost for 50 people.
Then,
We can write,
Catering cost = x
x = 225,00 * 50
x = 1,125,000 R
Therefore,
The catering cost was determined if the cost per person is R225,00. then the cost of 50 people is equal to = 1,125,000 R.

It is true. For all rational numbers a and b, a−b = a + (−b).
Given that,
To determine whether the statement, "For all rational numbers a and b, a−b = a + (−b)." is true or false.
In mathematics, a rational number is a number that can be described as the result of a fraction of value or does not have face value.
Here,
= a + (-b)
Since in the parenthesis there is a negative value, when we open the parenthesis the sign of the arithmetic operator will change accordingly,
So,

Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.61 and a standard deviation of 0.39. Using the empirical rule, what percentage of the students have grade point averages that are between 1.83 and 3.39?
As a result, 95% of the students had grade point averages ranging from 1.83 to 3.39.
What exactly is a normal distribution?A normal distribution is a data set design in which the majority of values cluster around the middle of the range and the remainder taper off symmetrically toward either end.
What is the significance of the term "normal distribution"?The normal distribution is also known as the bell curve because the probability density graph resembles a bell. It is also known as the Gaussian distribution, after German mathematician Carl Gauss, who described it initially.
According to the given data:A bell-curve distribution is a normal Distribution.
Let X be the grade point averages of undergraduate students at one university.
X ~ Normal Distribution(2.61,(0.39)2)
P(1.83 < X < 3.39)
= P(X < 3.39) - P(X < 1.83)
= P((X - μ)/σ < (3.39 - 2.61)/.39) - P(((X - μ)/σ)< (1.83 - 2.61)/039)
= P(z < 2) -P(z < -2)
= P(-2 < z < 2)
Thus, given a regular normal distribution (μ=0, σ =1), z is between 2 standard deviations away from the mean.
According to the Empirical Rule, 95% of the data obtained after a normal distribution is within two standard deviations of the mean.

Consider the system of linear equations.
−4x+6y = 4
2x−3y = k
Determine the constant so that the system of linear equations has infinitely many solutions. (Hint: Graph the equations in the same coordinate plane. What should you see in order for the system to have infinitely many solutions?)
The value of the constant k such that the system has infinitely many solutions is; -2.
What is the value of k such that the system has infinitely many solutions?It follows from the task content that the system of equations given upon observation are multiples.
Hence, by multiplying the second equation by -2; we have;
-4x +6y = 4
-4x +6y = -2k
Hence, for the system to have infinitely many solutions; 4 = -2k.
Ultimately, k = -2 by dividing both sides of the equation above by -2.

Rounding to an estimate, Sachin will have enough gas to go to both places before he runs out of gas.
What is an estimate?An estimate is an equivalent numerical value obtained by rounding off.
The result of an estimate is not an exact value. The value represents the nearest rounded value.
For instance, 75.9% can be estimated or rounded off to 76%. 32 minutes can be rounded off or approximated to ¹/₂ hour.
Data and Calculations:Driving distance before getting gas = 110 miles
The distance to his friend's house = 67 miles
The distance to his mom's house = 32 miles
The total distance to be covered on the available gas = 99 miles
Estimated distance to be covered = < 100 miles
Thus, using estimation, Sachin will still have more than 10 miles to drive before he gets gas.

What is the line of reflection?
A line of reflection is defined as a line that lies in a position between two identical mirror images so that any point on one image is the same distance from the line as the same point on the other flipped image
Now, from the attached image, we see that the two given congruent triangles are; ΔAHJ and ΔADB
Now, we see that the coordinates are transformed as folllows;
D(5, 2) → H(-5, 2)
B(3, 0) → J(-3, 0)
Now, this type of transformation follows the transformation rule; (x, y) → (−x, y). This means it was reflected over the y-axis.

P(x,y)----> P'(2h-x,2k-y)
P(-4,-4)---->P'(8,5)
Now comparing the corresponding sides;
2h+4=8
2h=8-4
2h=4
h=2
