The problem involves calculating the change received when Pedro buys four books at $7 each and pays with $30. The equation to solve this is c = $30 - $28. Therefore, Pedro receives $2 change.
Explanation:The subject of this question is a straightforward mathematics problem involving buying books and receiving change. We know that Pedro buys 4 books that each cost $7 and that he gives the cashier $30. To find out the change, represented as c , Pedro will get, we first figure out the total cost of the books: 4 books x $7 per book equals $28. Pedro pays with $30 so the calculation for the change would be: $30 (the amount Pedro paid) - $28 (the total cost of the books). This gives us the equation c = $30 - $28. Therefore, Pedro would receive $2 in change.

Pedro buys 4 books for $28 and pays with $30, so he would receive $2 in change. The equation to represent this is: c = $30 - $28.
To calculate the change Pedro receives, we can set up an equation where c represents the unknown change. Pedro buys 4 books at $7 each, so the total cost of the books is 4 books x $7/book = $28. He hands the cashier 3 ten dollar bills, which equals $30. The equation to find the change is then:
c = $30 - $28
Solving this equation, we get:
c = $2
So, Pedro would receive $2 in change after buying the books.

that of the reactants.
B) The mass of the reactants equals the mass of the products.
C) The mass of the reactants is less than the mass of the products.
D) The mass of the reactants is greater than the mass of the products.
Answer:
Option (B) is correct.
The mass of the reactants equals the mass of the products.
Step-by-step explanation:
According to law of conservation of mass :
In a balanced chemical equation, the mass of reactants is always equal to the mass of products.
Here, Water [tex]2H_{2}O[/tex] is the reactant which has 4 units of Hydrogen and 2 units of oxygen.
and [tex]2H_2+O_2[/tex] are products which also has 4 units 4 units of Hydrogen and 2 units of oxygen.
Thus, The mass of the reactants equals the mass of the products.
Thus, option (B) is correct.

Hexagon ABCDEF has has vertices A(-2,4), B(0,4), C(2,1), D(5,1), E(5,-2), F(-2,-2). Sketch the figure on the coordinate plane. What is the area of the hexagon?
Answer:
The area of the hexagon is 30 square units.
Sketch of figure on the coordinate plane below.
Step-by-step explanation:
Separate the hexagon into simpler shapes: a triangle, and two rectangles.
Find the area of the simpler figures. Count units to find the dimensions.
The triangle with vertices at (0, 4), (2, 1), and (0, 1):
A = 1 /2
BH
A = 1 /2
(2)(3)
A = 3
The area of the triangle is 3 square units.
The rectangle with vertices at (0, 1), (5, 1), (5, −2), and (0, −2):
A = LW
A = 5 × 3
A = 15
The area of the rectangle is 15 square units.
The rectangle with vertices at (−2, 4), (0, 4), (0, −2), and (−2, −2):
A = LW
A = 6 × 2
A = 12
The area of the rectangle is 12 square units.
Find the area of the hexagon.
A = 3 + 15 + 12
A = 30
The area of the hexagon is 30 square units.
A 1.5 lb package of seedless grapes costs $3.81. Round to the nearest
hundredth of a dollar. Find the unit price
A unit price of an object is simply the ratio of the total price of the object over the total mass, hence:
unit price = total price / total mass
unit price = $3.81 / 1.5 lb
unit price = $2.54 per pound
Answer:
$2.54
Final answer:
The unit price of the seedless grapes is calculated by dividing the total cost ($3.81) by the weight (1.5 lb), resulting in a unit price of $2.54 per pound.
Explanation:
To find the unit price of seedless grapes, you divide the total cost of the package by the weight of the package. If 1.5 lb of grapes costs $3.81, you would calculate the unit price by doing the following:
Divide $3.81 (total cost) by 1.5 lb (total weight).
The unit price is $2.54 per pound ($3.81 ÷ 1.5 lb = $2.54).
The unit price is helpful for comparing costs of similar products and making informed shopping decisions. Unit prices are displayed in stores to assist consumers with these comparisons.

what is the structure of a poem
Answer:
Poems are mostly written in lines and stanzas but it doesn't necessarily have a specific structure as such.
Explanation:
Structuring of a poem can be in multiple ways and there are no hard and fast rules. Though it is written in lines and stanzas, aside from that, there is no definite rule for writing a poem. Depending on the type of poem you are planning to write, it is required to try to follow the characteristics of the certain genre. For e.g, a sonnet is a fourteen line poem while an epic will deal with heroes, the free verse will be written in the author's own way, how long the lines will be or what shape it will take etc all depending on the writer. In short, the length of the line, the breaks, arrangement, rhythm or speed all depend on the content of the poem, and what it is about. Structure of a poem will all vary, depending on the type of poem written. So, to conclude, there is just no particular solution for writing a poem. It can be written in whatever way the writer wishes to, except that depending on the type of poetry s/he decides to write, it will have to follow the corresponding genre of that poetry.

Use the data set to answer the question. Correct value: 27 Data set: 19, 31, 22, 28, 24 Which best describes the data set?
The dataset shows moderate variability around a median of 24. The mean is 24.8, the mode is not available, and the range of the data is 12.
Explanation:To describe the given data set: 19, 31, 22, 28, 24, we need to analyze several statistical measures including mean, median, mode, range, and possibly standard deviation.
First, let's calculate the mean which is the total sum of the data points divided by the number of points. Therefore, (19+31+22+28+24)/5 = 24.8
Next, the median is the middle term when the data is written in ascending order. In this case, 24 is the median as it is the middle value.
This data set has no repeating numbers hence there is no mode.
The range tells us the spread of the values, determined by subtracting the smallest value from the largest. Therefore, 31( largest) - 19(smallest) = 12.
Without further data, standard deviation is impractical to calculate. Based on the numbers we do have, this dataset appears to have somewhat moderate variability and a median value of 24.
