Answer:
203 1/3 calories
Step-by-step explanation:
I make a proportion for inches of pizza to calories
[tex]\frac{6}{610}[/tex] = [tex]\frac{16}{x}[/tex] I know that a 6 inch pizza has 610 calories, so I am trying to figure out how many calories are in a 16 inch pizza.
I can cross multiply to get
6x = (16)(610)
6x = 9760 Divide both sides by 6
x = 1626 [tex]\frac{2}{3}[/tex] This is how many calories are in a whole pizza. Now I want to know how many calories are in 1 slice. I would take this number and divide by 8.
1626 2/3 as an improper fraction would be
[tex]\frac{4880}{3}[/tex] ÷ 8 Which is the same as
[tex]\frac{4880}{3}[/tex] x [tex]\frac{1}{8}[/tex] =[tex]\frac{4880}{24}[/tex]=203 [tex]\frac{1}{3}[/tex]
If the straight-line distance from her home to the university is 10. 3 km in a direction 25. 0° south of east, what was her average velocity in km/h?.
The average velocity in km/h is: 34.3km/hr
What is average velocity?Average velocity refers to speed at which the time intervals (t) change in position or displacement happens, divided by the change in position or displacement (x).
=> Average velocity = [tex]\frac{displacement}{time}[/tex]
Now,
The time taken is missing in the question; the time taken = 18 mins = [tex]\frac{18}{60}[/tex] hours.
The distance of her home to the university = 10.3 km
As, average velocity = [tex]\frac{displacement}{time}[/tex]
=> Velocity = [tex]\frac{10.3\times60}{18}[/tex] = 34.3 km/hr
Hence, the average velocity = 34.3 km/hr

Explain the difference between ethics and security. are they related? if so, how?
Information security and ethics is defined as an all encompassing term that refers to all activities needed to secure information and systems that support it in order to facilitate its ethical use
ETHICS:
Derived from the Greek word “ethos”, which means “way of living”, ethics is a branch of philosophy that is concerned with human conduct, more specifically the behaviour of individuals in society. Ethics examines the rational justification for our moral judgments; it studies what is morally right or wrong, just or unjust.
In a broader sense, ethics reflects on human beings and their interaction with nature and with other humans, on freedom, on responsibility and on justice. It can be said that in general, ethics is concerned with human independence when it focuses on the relationship that exists between humans and the world
This independence is the primary condition in ethical decision-making and in any objective analysis of the facts. Individuals demonstrate independence when, in a decision-making process, they choose to free themselves as much as possible from their conditioning. Insofar as this operation assumes a degree of lucidity that allows us to judge objectively and to decide what direction to take, it will be understood that making ethical decisions is difficult.
SECURITY:
Security for information technology (IT) refers to the methods, tools and personnel used to defend an organization's digital assets. The goal of IT security is to protect these assets, devices and services from being disrupted, stolen or exploited by unauthorized users, otherwise known as threat actors. These threats can be external or internal and malicious or accidental in both origin and nature.

At a cross-country track meet, Alicia ran 8 mph for the first part of the race, then increased her speed to 12 mph for the second part. If the race was 21 miles long and Alicia finished in 2 hours, how far did she run at the faster pace?
She ran 15 miles at a quicker speed based on the information supplied. See explanation below. This is a distance time problem.
What is the justification for the above result?The distances between the two "half" of the race are our unknowns here. We must assign them to variables - Alicia ran x miles in the first half of the race and y miles in the second.
Since the race is 21 miles in total, x and y together must add up to 21.
Hence,
x + y = 21
The speeds at which she raced and the total time involved are then given; we can link this to the distances using the speed and distance equation
d = st, or t = d/s.
Because she completed in two hours, the hours spent running the first and second parts must sum up to two hours, or:
x/8 + y/12 = 2
Two equations are sufficient to solve for two unknowns. We can approach this by multiplying the second equation by the LCM, 24
3x + 2y = 48
And rearrange the first to get y = 21 - x, which we can plug into the above. This gives us:
3x + 2(21 - x) = 48
3x + 42 - 2x = 48
x = 6
Use y = 21 - x again:
y = 21 - (6) = 15.
Recall that the question asks how long she ran at the faster speed - this would be the second half of the race, which we've labeled y, so 15 miles. But first, let's make sure our solution works.
Obviously, 15 + 6 = 21, thus the overall distance is correct.
In terms of time, 6 miles at 8 mph takes
6/8 =.75 hours = 45 minutes, whereas
15 miles at 12 mph takes 15/12 = 1.25 hours = 75 minutes.
As stated in the question, the total time to complete would be.
75 + 1.25 = 2 hours.
As a result, this solution is correct, as Alicia ran 15 miles at a quicker rate.

We can write -1.64 as:
- 1.64 = -164 / 100 ( decimal into fraction)
= -1640 / 1000
We can write 2.05 as:
2.05 = 205 / 100 (decimal into fraction)
= 2050 / 1000
We can write 1 9/40 as:
1 9/40 = 49 / 40 ( mixed fraction converted into the improper fraction)
49 / 40 × 25 / 25
= 1225 / 1000
Arranging it from least to greatest, we get that:
-2350 / 1000, -1640 / 1000, 1225 / 1000 and 2050 / 1000
Therefore, we get the fractions in ascending order as -2350 / 1000, -1640 / 1000, 1225 / 1000 and 2050 / 1000.

What mass of water will change its temperature by 3.0 °C when 635 J of heat is added to it?
The mass of water will change its temperature is 44.09 g.
Given that the temperature is change by 3.0°C when 635 J of heat is added to it.
Based on the given information, we know the following variables:
ΔT=3°C
Q=635J
C=(4.8 J)/(g×°C)
Here, we want to do is rearrange the equation to solve for m and this can be done by dividing both sides by C and ΔT to get m by itself like this:
m=Q/(ΔT×C)
Now, we want to substitute all the given values in the above formula, we get
m=635J/(3°C×(4.8J/(g×°C)))
m=635J/(14.4J/g)
m=44.09g.
Hence, the mass of water will change its temperature by 3.0 °C when 635 J of heat is added to it 44.09g.

Gabriel is deciding between two different movie streaming sites to subscribe to. Plan 1 cost $22 per month plus $1 per movie watched. Plan 2 cost $14 per month plus $3 per movie watched. Create a system of equations to represent this situation. Explains how many movies, x, would cause the two plans to have an equal monthly cost.
The number of movies that would make the monthly cost equal is 4.
What is the number of movies when the plans' cost would be equal?The total monthly cost is a function of the cost per month, total movies watched and the cost per movie.
The equations that represent the total cost of using the streaming sites would be in the form:
Total cost = cost per month + (number of movies watched x cost per movie)
Plan 1: $22 + ($x)
Plan 2: $14 + (3x)
When both plans have the same monthly cost, the two above equations would be equal
$22 + x =$14 + 3x
In order to determine the value of x, take the following steps:
Combine similar terms: $22 - $14 = 3x -x
Add similar terms together: $8 = 2x
Divide both sides of the equation by 2: $8 /$ 2 = x

What is the line of symmetry for the parabola whose equation is y=x²-12x + 7?
Ox=12
Ox=6
Ox=-6
Answer:
x = 6
Explanation:
completing square:
[tex]y=x^2-12x+7[/tex]
[tex]y=(x^2-12x)+7[/tex]
[tex]y=(x-6)^2+7-(-6)^2[/tex]
[tex]y=(x-6)^2+7-36[/tex]
[tex]y=(x-6)^2-29[/tex]
Comparing with quadratic equation [tex]y=ax^2 + bx+c[/tex], in vertex form where [tex]y = a(x-h)^2+k[/tex]. In this x - h = 0, x = h defines the symmetry of equation.
So here the symmetry for parabola:
x - 6 = 0
x = 6
Answer:
x = 6
Step-by-step explanation:
The axis of symmetry of a parabola is the x-value of its vertex.
For a quadratic function in the form [tex]y=ax^2+bx+c[/tex], the x-value of the vertex is:
[tex]x=-\dfrac{b}{2a}[/tex]
Given function:
[tex]y=x^2-12x+7[/tex]
Therefore:
[tex]a=1, \quad b=-12, \quad c=7[/tex]
So the axis of symmetry of the given quadratic function is:
[tex]\implies x=-\dfrac{b}{2a}=-\dfrac{-12}{2(1)}=\dfrac{12}{2}=6[/tex]

|x^2 + x -12| = x^2 +2x - 6
Take the absolute values of the expression
x² + x + 12 = x² + 2x - 6
collect like terms
x² - x² + x - 2x = -6 + 12
- x = 6
x = 6
|x-5|+|x+2|<8
Take absolute values
x + 5 + x + 2 < 8
collect like terms
2x + 7 < 8
2x < 8 - 7
Make 'x' the subject
x < 1/ 2
Thus, the values of x are 3/ 2, 6 and 1/ 2 respectively.

find the gradient and y-intercept of x-2y=8
(show your working)
x-2y=8
Step-by-step explanation:
x=8+2y
The gradient is 2
Answer:
gradient = [tex]\frac{1}{2}[/tex] , y- intercept = - 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c is the y- intercept )
given
x - 2y = 8 ( subtract x from both sides )
- 2y = - x + 8 ( divide through by - 2 )
y = [tex]\frac{1}{2}[/tex] x - 4 ← in slope- intercept form
with gradient m = [tex]\frac{1}{2}[/tex] and y- intercept c = - 4
Find the unit vectors that are parallel to the tangent line to the curve y = 2 sin(x) at the point 6 , 1 .
[1/2, sqrt(3)/2] and [-1/2, -sqrt(3)/2] are the unit vectors that are parallel to the tangent line to the curve.
Explain what a unit vector is?
A quantity with both magnitude and direction is referred to as a vector. A unit vector is one with a magnitude of 1. It also goes by the name Direction Vector.y=2sin(x)
dy/dx equals 2 cos x at pi/6 for x.
pi/6 = 2 cos pi/6 = 2 sqrt(3)/2 = sqrt = dy/dx(pi/6) (3)
the line sqrt(3) (x-pi/6) is the tangent to y at pi/6.
Atan Theta = sqrt is the angle with the x axis (3)
θ = pi/3 radians at 60 degrees
the vectors of units at (pi/6,1) [cos(60), sin(60)] and [-cos(60), -sin(60)] are parallel to this line.
[1/2, sqrt(3)/2] as well as [-1/2, -sqrt(3)/2]
