Xaivier played video games for 1 hour and 45 minutes before he went to bed. If he went to bed at 9:00 pm,what time did he start playing video games
Answer:7:15 pm
Step-by-step explanation:
We know he went to bed at 9:00 PM and spent 1 hr and 45 minutes playing games. Start by subtracting one hour away, so we get 8:00 PM. subtract 45 minutes from that and he would have started playing at 7:15 PM.

The profit in 2012 must be 4.5(in hundreds of dollars) to break even.
Profit for a company is defined as the difference between the revenue and cost of a product.
Let us take an example to learn more about profit.
A company sells a product at a price of 'S' dollars and the company spends 'C' dollars to manufacture the product. Here C includes the cost of raw materials, labor cost, transport etc.. Now the net profit for the company for selling one unit of this particular product is given by
Profit=S-C
When S>C the profit is positive.When S<C the profit is negative or loss .When S=C then the company breaks even.In the given chart it is shown the profit of the company is given as
2.5,1.75,-3.3 and -1.4 (in thousands of dollars) over 4 years.
Net profit over four years=[tex]2.5+1.75-3.3 -1.4=-0.45[/tex]
So over the past four years the company incurred a loss of
[tex]=0.45\times 1000\\[/tex]
[tex]=450[/tex] dollars
Now the company needs to break even in 2012.
So net profit must be zero over 5 years.
Therefore Profit in 2012=0-(-450)=450 dollars
Profit=4.5 (hundreds of dollars)

the central value of a set of data is expressed by the average of a list of data. It is defined mathematically as the ratio of the total number of data points to the number of units in the list. In terms of statistics, the term "mean" also refers to the average of a certain set of numerical data. The average of 2, 3, and 4 is, for instance, (2+3+4)/3 = 9/3 = 3. The center value of 2, 3, and 4 in this instance is 3, thus. Finding the mean value of a bunch of numbers is the definition of average.
Average = Total Values / Total Values

How many solutions does the following system of equations have? 5x−2y=10 y=5/2x-5
Answer:
Infinite number of solutions
No unique solution
Step-by-step explanation:
5x - 2y = 10 (1)
y = 5/2x - 5 (2)
Multiply (2) by 2 to get
2y = 5x - 10
Rewrite the above equation as 5x - 2y = 10 (3)
Since both equations are the same, we are provided with a single equation in 2 variables there are infinite solutions
You are going down a road with a 5% grade.
You are going down 1 feet every 20 feet horizontally.
The slope of the road as a reduced fraction is??
The slope of the road as reduced fraction [tex]\frac{1}{20}[/tex] for grade which is 5%.
The slope of a road is defined as the ratio of the vertical height that a road rises to the horizontal distance covered to rise to that height.
While slope is expressed as a fraction grade is the percentage form of that fraction. The slope can also be defined as [tex]tan[/tex] [tex]\theta[/tex] where [tex]\theta[/tex] is the angle of elevation of the road. For example a slope of [tex]\frac{1}{4}[/tex] has a grade of 25%.
Here the given grade is 5%.
Per-cent refers to per one-hundred. So a 5% grade is 5 per one -hundred.
That means if the road is climbing then for every 100 units of horizontal distance covered, the altitude increases by 5 units.
Now slope of the road=vertical distance ÷ horizontal distance
[tex]=\frac{5}{100}\\=\frac{1}{20}[/tex]
Therefore we can say that the slope of the road is [tex]\frac{1}{20}[/tex]

Find the unique solution to this system of equations. Give your answer as a point
Answer:
(x, y, z) = (-4, -5, 2)
Step-by-step explanation:
You want the solution to the 3×3 system of equations ...
3x -y -4z = -15-4x -4y -z = 342x +3y +5z = -13ToolsThere are many tools available for solving a system of equations. A typical hand-held graphing calculator offers at least two methods. An online graphing calculator solution is shown in the attachment.
For the attached solution, we defined z in terms of x and y using the second equation. This effectively reduces the system to a 2×2 system, which is easily solved. The same "substitution" method can be used when solving the system by hand.
The graph shows the solution to be (x, y, z) = (-4, -5, 2).
Manual solutionUsing z = -4x -4y -34 from the second equation, the system reduces to ...
3x -y -4(-4x -4y -34) = -15
19x +15y = -151
and
2x +3y +5(-4x -4y -34) = -13
-18x -17y = 157
Writing these equations in general form, we have ...
19x +15y +151 = 018x +17y +157 = 0The "cross multiplication method" gives the solution for x and y as ...
D = (19)(17) -(18)(15) = 53
x = (15(157) -17(151))/D = -212/53 = -4
y = (151(18) -157(19))/D = -265/53 = -5
Then z is ...
z = -4(-4) -4(-5) -34 = 16 +20 -34 = 2
The solution is (x, y, z) = (-4, -5, 2).

Based on the two equivalent forms of the function h(t)=96t−16t2=t⋅(96−16t),At what time(s) is the ball 50 feet above the ground?
the height will be 50 ft after 0.575 seconds and after 5.424 seconds.
At what time(s) is the ball 50 feet above the ground?The equation that models the height is:
h(t) = 96*t - 16*t^2
Here we want to find the time such that the height is 50ft, then we need to solve the equation:
h(t) = 50 = 96*t - 16*t^2
Now we can solve that for t, we have the quadratic equation:
50 = 96*t - 16*t^2
0 = -16*t^2 + 96*t - 50
Then the solutions are:
t = (-96 ± √(96*96 - 4*(-50)*(-16))/(2*-16)
t = (-96 ± 77.6)/(-32)
The two solutions are:
t = (-96 + 77.6)/(-32) = 0.575t = (-96 - 77.6)/(-32) = 5.424This means that the height will be 50 ft after 0.575 seconds and after 5.424 seconds.

9x-6y= 18
By evaluating the given linear relation, we conclude that the complete table is:
x: 2, 0, 1, 14/3
y: 0, -3, -3/2, 4
How to determine the values of the missing entries?Here we have the linear relation:
9x - 6y = 18
And we want to complete the given table, to do so, we just need to evaluate the relation in the given values and with that we can find the missing ones.
For example, the first pair has y = 0.
Evaluating that we get:
9x - 6*0 = 18
9x = 18
x = 18/9 = 2
Then we have the pair (2, 0).
The second has x = 0, replacing that we get:
9*0 - 6*y = 18
y = 18/-6 = -3
So we have the pair (0, -3)
The third has x = 1, replacing that:
9*1 - 6y = 18
-6y = 18 - 9 = 9
y = 9/-6 = -3/2
So we have the pair (1, -3/2)
The last value on the table is y = 4, replacing that:
9x - 6*4 = 18
9x - 24 = 18
9x = 18 + 24 = 42
x = 42/9 = 14/3
Then the complete table is:
x: 2, 0, 1, 14/3
y: 0, -3, -3/2, 4

I have 200 hours to make as much Lemonade as possible, and I can make 1 pitcher every 10 minutes.
Write an inequality to represent my time constraint.
Answer:
33.33
Step-by-step explanation:
Well, we already know the amount of time it takes to make the lemonade, and we know the rate as well.
We need to find out how many pitchers you can make in an hour. If you can make one pitcher in 10 minutes, then you can make 6 pitchers in 60 minutes, AKA an hour.
So we make 6 pitchers per hour.
If we make 6 an hour, then we multiply 6 by 200 to get the number of pitchers we can make in 200 hours.
We can make 33.33 pitchers in 200 hours
