Answer:
D) 5
Step-by-step explanation:
If we multiply 5 and an odd number, the end value will not be 0, 1, and 3. For example,
5 × 1 = 5
5 × 9 = 45
Therefore, in both the product, the end value is 5 and not 0, 1, and 3.
Therefore, option D is correct.
If we multiply 5 by any of the odd number, we can get the end value of 5. The following examples are the valid reasons why we will get 5.
5 × 3 = 15
5 × 5 = 25
So, option A, B, and C are wrong.

Out of the 1236 employees who work for a particular company, 748 of them work in an office. One employee is selected every month to receive a free
lunch. The probability that the selected employee does not work in an office is
Answer:
458
Step-by-step explanation:
Final answer:
The probability that the selected employee does not work in an office is calculated by dividing the number of employees not working in an office (488) by the total number of employees (1236), resulting in a probability of approximately 0.395.
Explanation:
The question asks for the probability that the selected employee does not work in an office from a total of 1236 employees, where 748 work in an office. To find this, we first need to determine the number of employees who do not work in an office.
Employees not working in an office = Total employees - Employees working in an office
= 1236 - 748 = 488
Now, the probability of selecting an employee who does not work in an office is calculated by dividing the number of employees not working in an office by the total number of employees:
Probability = Number of employees not working in an office / Total number of employees
Probability = 488 / 1236
Therefore, the probability that the selected employee does not work in an office is approximately 0.395.

The equations for the regular cost is [tex]y=18.50 x[/tex] and
The equation for the party special is [tex]y=15 x+28[/tex],
where y is the total cost in dollars and x is the number of students in the group.
Step-by-step explanation:
Step 1:
The regular cost per person is $18.50 per person.
So to calculate the total cost, all we need to do is multiply the number of students in the study group with the cost per person i.e. $18.50.
So the equation is [tex]y=18.50 x[/tex].
If x = 5, [tex]y=18.50(5)[/tex] = $92.50,
If x = 10, [tex]y=18.50(10)[/tex] = $185.00.
Step 2:
The party special costs $15 per person but has an additional fee of $28 for a private room where they can have lunch.
So to calculate the total cost we multiply the number of students in the group with the cost per person i.e. $15 and add it with the private room fee i.e. $15.
So the equation is [tex]y=15 x+28[/tex].
If x = 5, [tex]y=15 (5)+28[/tex] = $103.00
If x = 10, [tex]y=15 (10)+28[/tex] = $178.00.

You move down 3 units and right 6 units. You end at (4, -5). Where did you start?
(-2, -2)
Step-by-step explanation:
In this problem, you only know the coordinates of the final point and the distance moved in order to get there (which was moving 3 units down and 6 units to the right). If you want to find the starting point, you simply have to go backwards by subtracting 3 from -5 because the y coordinates move upwards/downwards, and then subtracting 6 from 4 because the x coordinates go left/right in order to get your final answer, (-2, -2).
The sequence of movements can be reversed to find the initial position, which is (-2, -2).
To determine the starting point, we can reverse the given movements: moving down 3 units and right 6 units from the final position (4, -5). If we move 3 units up from the final y-coordinate (-5), we get -5 + 3 = -2.
Similarly, if we move 6 units left from the final x-coordinate (4), we get 4 - 6 = -2. Therefore, the starting point is (-2, -2).
To visualize this, imagine a coordinate plane where moving down represents decreasing the y-coordinate and moving right represents increasing the x-coordinate.
Starting at (-2, -2), moving down 3 units brings us to (-2, -5), and then moving right 6 units from there leads us to the final position (4, -5).

The line 2y - x + 5 = 0 and the curve (10 – x)^2+ (y – 5)^ 2= 10 intersect at points A and B.
Find the coordinates of A and of B.
Answer:
A(9, 2 ), B(13, 4 )
Step-by-step explanation:
Given the 2 equations
2y - x + 5 = 0 → (1)
(10 - x)² + (y - 5)² = 10 → (2)
Rearrange (1) expressing x in terms of y by adding x to both sides
x = 2y + 5 → (3)
Substitute x = 2y + 5 into (2)
(10 - (2y + 5))² + (y - 5)² = 10, that is
(10 - 2y - 5)² + (y - 5)² = 10
(5 - 2y)² + (y - 5)² = 10 ← expand the factors using FOIL
25 - 20y + 4y² + y² - 10y + 25 = 10
5y² - 30y + 50 = 10 ( subtract 10 from both sides )
5y² - 30y + 40 = 0 ( divide through by 5 )
y² - 6y + 8 = 0 ← in standard form
(y - 2)(y - 4) = 0 ← in factored form
Equate each factor to zero and solve for y
y - 2 = 0 ⇒ y = 2
y - 4 = 0 ⇒ y = 4
Substitute these values into (3) for corresponding values of x
y = 2 : x = 2(2) + 5 = 4 + 5 = 9 ⇒ (9, 2 )
y = 4 : x = 2(4) + 5 = 8 + 5 = 13 ⇒ (13, 4 )
Since we are not given the position of A or B in relation to each other then either of the points can represent A or B, that is
A(9, 2), B(13, 4)
OR
A(13, 4), B(9, 2)

Step-by-step explanation:
A is K divided by the wavelength (m) 301,500 / 450
B is wavelength(m) multiplied by the Frequency (Thz) 520x580
C is K divided by the Frenquency (Thz) 302400 / 540
The value of a is 670, b is 301,600, and c is 560.
What is Inverse Variation?When a variable varies inversely with the other variable, i.e. on increasing one variable the other decreases is called Inverse Variation.
The table consists of data of wavelength, frequency and k, the product of wavelength and frequency.
The missing values of a, b, and c has to be determined.
The wavelength is in inverse relation to frequency, on increasing the wavelength, the frequency decreases.
Wavelength ∝ ( 1 / frequency)
Wavelength * Frequency = k
For determining a,
450 * a = 301500
a = 301500/450 = 670
a = 670
For determining b,
520 * 580 = b
b = 301600
For determining c,
c * 540 = 302400
c = 302400 / 540
c = 560

Absolute value equation |x-3|=5
Answer:
x = - 2, x = 8
Step-by-step explanation:
The absolute value function always returns a positive value, but the expression inside can be positive or negative, thus
x - 3 = 5 OR - (x - 3) = 5
Solving both equations
x - 3 = 5 ( add 3 to both sides )
x = 8
OR
- x + 3 = 5 ( subtract 3 from both sides )
- x = 2 ( multiply both sides by - 1 )
x = - 2
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are solutions.
x = 8
| 8 - 3 | = | 5 | = 5 = right side
x = - 2
| - 2 - 3 | = | - 5 | = 5 = right side
Thus the solutions are x = - 2, x = 8
The equation given is the same as x - 3 = 5 or -(x - 3) = 5
Steps to solve:
x - 3 = 5
x - 3 + 3 = 5 + 3
x = 8
Steps to solve:
-(x - 3) = 5
-x + 3 = 5
-x + 3 - 3 = 5 - 3
-x = 2
-x/-1 = 2/-1
x = -2
Therefore, the solutions are x = 8 and x = -2

The length of a rectangular piece of sheet metal is 3 times it’s width. What is its length if it’s area is 192 square centimeters
To find the missing number, you will need to divide the numbers you already have.
192 divided by 3 = 64
Your answer/length will be 64.
Area = 192
Width = 3
Length = 64
64 x 3 = 192
Hope this helps :)
To determine the length of the rectangular piece of sheet metal with an area of 192 square centimeters and a given length-to-width ratio, solve for the width using the area formula, then use the ratio to find the length. The calculated length is 24 centimeters.
The problem involves finding the length of a rectangle given the area and the relationship between the length and width. Let's denote the width of the rectangle as w and the length as L. We are given that L = 3w and the area (A) of the rectangle is 192 square centimeters. The area of a rectangle is calculated by multiplying its length and width.
A = L x w
Substituting L from the given relationship into the area equation:
192 cm² = (3w) x w
Now we can solve for w:
192 cm² = 3w²
w² = 192 cm² / 3
w² = 64 cm²
w = 8 cm
Now, use the value of w to find L:
L = 3 x 8 cm
L = 24 cm
Therefore, the length of the rectangular piece of sheet metal is 24 centimeters.

A lizard is jumping across the water in search of food. The equation h = -12t2 + 6t
models the lizard's height in feet above the water t seconds after he jumps. How long
after Jumping is he back on the water?
To find the time when the lizard is back on the water, set the height equation equal to zero and solve for t. The lizard is back on the water 1/2 second after jumping.
Explanation:To find the time when the lizard is back on the water, we need to set the height, h, equal to zero, and solve for t in the given equation, h = -12t^2 + 6t.
Substitute 0 for h:
0 = -12t^2 + 6t
Now we can solve for t. Rearrange the equation to quadratic form:
12t^2 - 6t = 0
Factor out a common factor of 6t:
6t(2t - 1) = 0
Set each factor equal to zero:
t = 0 or 2t - 1 = 0
If t = 0, it means the lizard is on the water at the time it jumps. Therefore, t = 0 is not the solution we're looking for. If 2t - 1 = 0, solving for t:
2t = 1
t = 1/2
Therefore, the lizard is back on the water 1/2 second after jumping.
