What is a product?
In mathematics, a product is the outcome of multiplication or an expression that specifies the elements, or objects that can be numbers or variables, that are to be multiplied. The commutative law of multiplication states that the result is unaffected by the order of multiplying real or complex numbers. A number that is obtained by multiplying two or more other numbers together is known as the product .Multiplication in other algebras in general, as well as matrix multiplication as an example, is non-commutative.To learn more about products, refer:

A recipe book shows measurement conversions for cups to tablespoons. It shows that 0.5 cup equals 8 tablespoons and 1.5 cups equals 24 tablespoons.
Write an equation that shows the proportional relationship between cups and tablespoons where c represents cups and n represents tablespoons.
n = 0.0625c
c = 0.0625n
n equals 0.5 over 8 times c

AND THANK YOU SO MUCH
An equation that shows the proportional relationship between cups (c) and tablespoons (n) is: B. c = 0.0625n
What is a proportion?A proportion is an equation which is typically used to indicate the equality of two (2) ratios. Therefore, proportions can be used in mathematics to show that two (2) ratios are equivalent and then used to calculate or determine all of the unknown quantities.
Mathematically, a proportional relationship can be represented by the following equation:
y = kx
Where:
y and x represent the variables in a proportional relationship.k is the constant of proportionality.Let the cups be represented by c.
Let the tablespoons be represented by n.
Next, we would determine the constant of proportionality (k) as follows:
c = kn
Making k the subject of formula, we have:
k = c/n
k = 0.5/8 ≡ 1.5/24
k = 0.0625.
Substituting the parameters into the equation for a proportional relationship, we have;
c = kn
c = 0.0625n

Write the next three terms of each of the following sequences.
-67, -75, -83,
Answer:
- 91, - 99, - 107
Step-by-step explanation:
there is a common difference between consecutive terms , that is
- 75 - (- 67) = - 75 + 67 = - 8
- 83 - (- 75) = - 83 + 75 = - 8
thus to find the next 3 terms subtract 8 from the previous term
- 83 - 8 = - 91
- 91 - 8 = - 99
- 99 - 8 = - 107
the next 3 terms are - 91 , - 99 , - 107
A bee flies at 15 feet per second directly to a flowerbed from its hive. The
bee stays at the flowerbed for 10 minutes, and then flies directly back to
the hive at 9 feet per second. It is away from the hive for a total of 14
minutes. Let d be the distance of the flowerbed from the hive. How far is
the flowerbed from the hive?
The flowerbed is 3600 feet away from the beehive.
How is distance related to speed and time?
Speed is determined by dividing the distance travelled by the time taken to travel it. It gives the distance travelled and the time it took to travel that distance.
Distance is equal to speed times time, and time is equal to distance divided by speed. As a result, as the speed increases, the amount of time required will decrease, and vice versa.
Mathematically, Distance = Speed*Time
Given, the total time of flight for the bee = (14 - 10) minutes = 240 seconds
Speed of the bee = 15 feet s⁻¹
Distance of the flowerbed from the hive = d
Thus using the formula described above in the literature part, we get,
Distance, d = Speed * Time = 15*240 = 3600 feet
Thus, the flowerbed is 3600 feet away from the beehive.

which one of these constructiond would construct a line of relection that takes the point A to point B
Option D is the constructions that would construct a line of reflection from point A to point B. Make a line parallel to line AB.
A line parallel to line AB will generate a line of reflection that connects points A and B because a parallel line never intersects, resulting in direct imagery of Line AB.
What is a Parallel lines?Parallel lines are two lines in the same plane that are equal distance apart and never intersect. They can be both horizontal and vertical in orientation.
We have,
-Make a perpendicular bisector of segment AB.
A perpendicular bisector does not create a line of reflection that connects points A and B, but rather divides the line AB into two equal parts.
-Draw a line through B that is perpendicular to segment AB.
A perpendicular line through B to segment AB WILL NOT Make a line of reflection from point A to point B.
-Build the line that connects A and B.
A line passing through A and B will NOT create a line of reflection that connects points A and B, but will instead create Line A and B and not its reflection.
Hence,
Make a line parallel to line AB.
A line parallel to line AB will generate a line of reflection that connects points A and B because a parallel line never intersects, resulting in direct imagery of Line AB.

How much would you tip someone if the total cost of the meal is 13.40$?
The amount that you would tip someone if the total cost of the meal is 13.40$ is: $2.01.
How much is the standard tip in the United States?In the United States, the standard tip for good service is 15%. So, assuming that the meal service offered could be classified as a good service, we can say that 15% of 13.40$ will be the tip to provide.
15% of 13.40$ is equal to $2.01.
Therefore, the amount that the person who received the service is expected to pay is $2.01. Also, note that the tip for delayed service is 10% and the tip for excellent service is 20%. Bad service requires no tip.

By using the fact that the two triangles are equivalent, we will find that the value of n must be 18.4
How to find the length of n?Here we can see that the horizontal line divides the triangle in such a way that the left and right sides are divided in two halfs. (we can see this because both parts have the same symbol on them)
Also both of these triangles are equivalent, so:
if x is the measure of each part in the right side we can write the equivalent relation
11.3/x = (n + 4.2)/(2x)
Now wen solve this for n:
(11.3/x)*2x = (n + 4.2)
22.6 = n + 4.2
22.6 - 4.2 = n

1. The difference between the number of squares in subsequent figure is 5 - 3 = 7 - 5 = 2
Which gives;
The equation that gives the number of blocks in each figure is a linear equation of the form, y = m•x + c
Where;
