Which of the quantities below represents a velocity?
A. 25 m/s
B. 10 km/min
C. 15 mi/h eastward
D. 3 mi/h
Step-by-step explanation:
Velocity is a measure of the rate at which an object moves through space. It is a vector quantity, meaning that it has both magnitude (size) and direction. The standard unit for velocity is meters per second (m/s).
Of the quantities listed above, the following represent velocities:
A. 25 m/s: This represents a velocity of 25 m/s, because it gives both the speed (magnitude) and direction of the object's movement.
C. 15 mi/h eastward: This represents a velocity of 15 miles per hour (mi/h) in an eastward direction, because it gives both the speed and direction of the object's movement.
D. 3 mi/h: This represents a velocity of 3 mi/h, because it gives both the speed and direction (implied to be eastward or westward) of the object's movement.
B. 10 km/min: This does not represent a velocity, because it gives the distance traveled (10 km) but not the time over which the distance was traveled. Without the time, it is not possible to determine the speed or rate of movement.

Last year, the average monthly revenue at the Cedarburg Times newspaper was $66,490. This year, the average monthly revenue so far has been $59,841. What is the percent of decrease in the average monthly revenue?
The percent of the decrease in the average monthly revenue is 10%.
How to calculate the percent of the decrease?We can calculate the percent of the decrease by using the following formula:
The percent of the decrease = (previous revenue - current revenue) / previous revenue × 100%
Last year, the average monthly revenue at the Cedarburg Times newspaper was $66,490.
This year, the average monthly revenue so far has been $59,841.
The percent of the decrease = (previous revenue - current revenue) / previous revenue × 100%
previous revenue = $66,490.
current revenue = $59,841
The percent of the decrease = ($66,490 - $59,841) / $66,490 × 100%
The percent of the decrease = 6,649 / $66,490 × 100%
The percent of the decrease = 0.1 × 100%
Apply the multiplication operation, and we get
The percent of the decrease = 10%
Thus, the drop in the average monthly revenue is 10%.

Solve the equation:5(3+6a)=-15+6(5+5a)
Answer:
0.5Step-by-step explanation:
To solve the equation 5(3+6a) = -15+6(5+5a), we need to use the rules of algebra to isolate the variable "a" on one side of the equation and simplify the other side.
First, we can distribute the 5 on the left side of the equation to obtain 53 + 56a = -15+6(5+5a). This gives us 15 + 30a = -15+6(5+5a).
Next, we can distribute the 6 on the right side of the equation to obtain 15 + 30a = -15+65 + 65a. This gives us 15 + 30a = -15+30 + 30a.
Now we can combine like terms on both sides of the equation to obtain 30a = -15 + 30, which simplifies to 30a = 15. Finally, we can divide both sides of the equation by 30 to obtain a = 0.5.
Therefore, the solution to the equation 5(3+6a) = -15+6(5+5a) is a = 0.5

If you have a good credit rating and can afford monthly payments of $539, how much can you borrow from E-loan? What is the total interest you will pay for this loan?
I can borrow $17717.48from E-Loan.
The interest I will pay for the loan is $1,686.52
Now, According to the question:
We know,
The formula of present value is
PV = PMT [tex](\frac{ 1-(1+i)^-^n}{i} )[/tex]
PMT = The monthly payment = $539
i= Rate of interest per period = 6%/12 = 0.005

a rectangular field will be bounded by a wall on one side and by fencing on the other three sides. what is the largest area you can enclose with 120 feet of fencing?
The largest area you can enclose with 120 feet of fencing is 900 square feet.
To find the maximum area you can enclose with 120 feet of fencing, you can use the formula for the area of a rectangle, which is A = lw, where A is the area, l is the length, and w is the width. Since the length of the rectangle is bounded by a wall and cannot be changed, the width will be the variable we seek to maximize.
Since the perimeter of the rectangle is fixed at 120 feet, we can set up the following equation:
2l + 2w = 120
This equation represents the total length of the fence needed to enclose the rectangular field. We can solve for w in terms of l by rearranging the equation as follows:
2w = 120 - 2l
w = (120 - 2l)/2
To maximize the area of the rectangle, we want to maximize the value of w. We can do this by making l as small as possible, since this will make w as large as possible. Therefore, we can set l equal to the minimum possible value, which is the length of the wall.
Let's say the length of the wall is x feet. Then, we can substitute x for l in the equation for w to find the maximum possible width:
w = (120 - 2x)/2
To find the maximum area, we can then substitute this value for w back into the formula for the area of a rectangle:
A = lw
= x((120 - 2x)/2)
= (120x - 2x^2)/2
This is a quadratic function, and we can use the techniques for maximizing quadratic functions to find the maximum value of A. To do this, we take the derivative of the function and set it equal to zero:
A' = (120 - 4x)/2 = 0
120 - 4x = 0
x = 30
Substituting this value back into the equation for A, we find that the maximum possible area is:
A = (120 * 30 - 2 * 30^2)/2
= (3600 - 1800)/2
= 1800/2
= 900 square feet

How do you identify the type of similarity that two triangles might be?
To easily recognize comparable triangles, you can apply three theorems that are peculiar to triangles.
Two triangles can be compared using one of three theorems: Angle-Angle (AA), Side-Angle-Side (SAS), and Angle-Angle-Side (SS-AS) (SSS).
The symbol representing two triangles with the same angles on all three sides is SSS, which stands for "side, side, side." If two triangles' third sides match those of another triangle, the two triangles are said to be congruent.
The SAS regulation states as much. If the two sides and included angle of one triangle match the two sides and included angle of another triangle, the triangles are congruent. Any angle formed by two specified sides is considered to be an included angle.
A triangle is comparable to another if its two matching angles are congruent, according to the AA postulate of Euclidean geometry. The AA postulate is derived from the observation that the total internal angle of a triangle is always equal to 180°.

what is the largest integer that always divides $(n 1)(n 3)(n 5)(n 7)(n 9)$ for all positive even integers $n$?
The largest integer that always divides (n+1)(n+3)(n+5)(n+7)(n+9) for all positive even integers n is 15.
What is positive integer?Positive integers are numbers such as 1, 2, 3, etc. They are also called countable or natural numbers. A positive number is any number greater than zero.
Let P(n) = (n+1)(n+3)(n+5)(n+7)(n+9) be a polynomial for all positive even integers, n . We have to calculate the largest integer that always divides the P(n) .
Let "l" be the largest integer that divides P(n) for each n∈N . Then, l must divide both P(1) and P(2)
i.e, P(1) = (1+1)(1+3)(1+5)(1+7)(1+9) = 2×4×6×8×10
= 2^8×5×3
P(2) = 3×5×7×9×11 , hence , l divides 15.
Since, n + 5 ≡ (n+2) mod(3), one (and exactly one) of the numbers n+1 , n+3 , n+5 must be multiple of 3 . Thus, 3/P(n) for each n∈N.
Since, n+7 ≡ (n+2)mod(5) and n+9 ≡ (n+4)mod(5),
one (and exactly one) of the numbers n+1 , n+3 , n+5 , n+7 and n+9 , must be multiple of 5.
Thus, 5/P(n) for each n∈N.
Therefore, 15/p(n) for each n∈N , so that l = 15 .
So, required value of n is 15.
