The Kendal Company manufactures automobile engine parts. Running the manufacturing operations requires 12 watts (units of electricity per hour). The amount of electricity required to run the manufacturing operations and lighting the facility is given by y = 12x + 24, where x is the number of hours of manufacturing and y is the amount of electricity expended. How much electricity is used on a day when no parts are manufactured? (x 0, y 0)
Answers
Answer:
The answer is 24 watts.
Step-by-step explanation:
Running the manufacturing operations requires 12 watts (units of electricity per hour).
The amount of electricity required to run the manufacturing operations and lighting the facility is given by [tex]y=12x+24[/tex]
Here x is the number of hours of manufacturing and y is the amount of electricity expended.
When there are no parts manufactured, then x = 0
[tex]y=12(0)+24[/tex] = 24.

Find an equation of a linear function given h(1)=6 and h(4)=-3
Answers
We can rewrite this in the form of h (t):
at t = 1, h = 6
at t = 4, h = -3
The linear equation is in the form of:
h = mt + b
where m is the slope and b is the h-intercept
So calculating for the slope m:
m = [-3 – 6] / (4 – 1)
m = (-9) / 3
m = -3
So,
h = -3t + b
Solving for b by plugging in any pair:
6 = -3(1) + b
b = 9
Therefore:
h = -3t + 9

I thought of a number, multiplied it by 2 1/2 , divided the result by 1 1 /5 , subtracted 7/18 from it, and got 1 5/6 . What was my number?
Answers
The student's original number was 1 3/45. This was obtained by reversing the processes described in the problem and applying them to the final number.
Explanation:
To solve this problem, we basically need to reverse the operations given in the problem and perform them on the final answer 1 5/6. Let's start:
Add 7/18 to 1 5/6. The sum is 2. Multiply 2 by 1 1/5. The product is 2 2/5. Finally, divide 2 2/5 by 2 1/2. The quotient, which is the number the student originally thought of, is 48/45 or 1 3/45.
So the student's original number was 1 3/45.

The Hamptons family has a fish tank holding 10,450 ml of water. The water is leaking at a rate of 270 ml per minute. Define the input and output in the given scenario
Answers
The input is any variable which goes into the system. In this case there is no input.
While the output is any variable going out of the system. In this case the output is the amount of water which leaked out.
Answer:
The number of minutes represents input and remaining water represents output.
Step-by-step explanation:
Given,
The original quantity of the water in the tank = 10,450 ml,
Also, the quantity of the water leaked per minute = 270 ml,
Thus, the quantity water leaked in x minutes = 270x
∵ Remaining water in the tank ( say y ) = Original water - leaked water
⇒ y = 10450 - 270x,
Which is the equation that shows the given scenario.
In this equation, x represents the input value and y represents the output value,
Hence, the number of minutes represents input and remaining water represents output.

Whats the rule for this pattern, 3,1.5,0,-1.5,-3
Answers
Final answer:
The rule for the pattern 3, 1.5, 0, -1.5, -3 is to subtract 1.5 from the previous term in the sequence.
Explanation:
The rule for the number pattern 3, 1.5, 0, -1.5, -3 is subtracting 1.5 from the previous number each time. To identify this, observe the difference between consecutive terms:
From 3 to 1.5 we subtract 1.5 (3 - 1.5 = 1.5).
From 1.5 to 0 subtract 1.5 (1.5 - 1.5 = 0).
From 0 to -1.5 subtract 1.5 (0 - 1.5 = -1.5).
And from -1.5 to -3, again subtract 1.5 (-1.5 - 1.5 = -3).
This pattern consistently decreases by 1.5, and it can be continued indefinitely by keeping this rule in mind.
what is 3(7x-6)<-81?
Answers
3(7x - 6) < -81
First, we need to apply the Distributive Property to the left side of the inequality.
This mathematical term means to multiply the number or variable outside of the parenthesis to all numbers and/or variables on the inside of the parenthesis.
Here's an example;
3(2 + 1)
Multiply the outside number by all inside numbers.
3(2) + 3(1)
Multiply.
6 + 3
Simplify the expression.
9.
Now that we've explained our concept for distributing, let's apply what we now know to our current problem.
3(7x - 6) < -81
Apply the Distributive Property to the left side of the inequality.
3(7x) + 3(-6)
Multiply.
21x - 18
We now have:
21x - 18 < -81
Now we need to isolate the variable. To do this, we need to make sure that 'x' is by itself. Since x is being subtracted by 18, we need to apply the opposite order of operations to both sides of the inequality.
Add 18 to both sides to isolate the variable.
21x < -63
We now need to solve for x. To solve for x, we need to divide both sides by 21, as iur variable is being multiplied by 21.
We are now left with:
x < -3
This is your final solution to your inequality.

a. The fraction of states with a four-star hotel ........ (Simplify your answer.)
Answers
the portion of states that have a four star hotel compared to how many states there are uses the fraction 35/50. You must simplify this, and to do this you find the greatest value with can divide the numerator and the denominator. This is 5. 35/5=7, and 50/5= 10, therefore, 7/10
(b) 15
simply subtract the number of states which have a four star hotel from the total number of states
(c) 3/10
this is the same logic as (a). use the answer you got from part b, and simplify the fractions
The fraction of states with at least one four-star hotel is 7/10, 15 states do not have a four-star hotel, and the fraction of states without a four-star hotel is 3/10.
Answer to Student's Question
(a) To find the fraction of states with at least one four-star hotel, we divide the number of states with a four-star hotel by the total number of states. Therefore, the fraction is 35/50, which simplifies to 7/10.
(b) To determine how many states do not have a four-star hotel, we subtract the number of states with a four-star hotel from the total number of states: 50 - 35 = 15. So, there are 15 states without a four-star hotel.
(c) Finally, the fraction of states without a four-star hotel is the number of states without such hotels divided by the total number of states. This is 15/50, which can be simplified to 3/10.

If r = x, y, z and r0 = x0, y0, z0 , describe the set of all points (x, y, z) such that |r − r0| = 5.
Answers
We are concern about the vector (x-x0, y-y0, z-z0) equaling to 5.
This happens when √(x-x0)^2 + (y-y0)^2 + (z-z0)^2 = 5
Square both side:
(x-x0)^2 + (y-y0)^2 + (z-z0)^2 = 25 , a sphere
Which you will recognize as a circle of radius one centered at (x0, y0, z0)
Answer:
Point [tex]\left ( x,y,z\right )[/tex] represents a sphere
Step-by-step explanation:
Take [tex]r=\left ( x,y,z \right )\,,\,r_0=\left ( x_0,y_0,z_0 \right )[/tex]
We need to describe the set of all points (x, y, z) such that [tex]\left | r-r_0 \right |=5[/tex]
Solution :
For [tex]r-r_0=\left ( x,y,z \right )-\left ( x_0,y_0,z_0 \right )[/tex], we will subtract the respective elements .
[tex]r-r_0=\left ( x,y,z \right )-\left ( x_0,y_0,z_0 \right )=\left ( x-x_0,y-y_0,z-z_0 \right )[/tex]
Therefore, [tex]\left | r-r_0 \right |=\sqrt{(x-x_0)^2+(y-y_0)^2+(z-z_0)^2}[/tex]
As [tex]\left | r-r_0 \right |=5[/tex], we get
[tex]\sqrt{(x-x_0)^2+(y-y_0)^2+(z-z_0)^2}=5[/tex]
On squaring both sides, we get
[tex]\left ( \sqrt{(x-x_0)^2+(y-y_0)^2+(z-z_0)^2} \right )^2=5^2\\(x-x_0)^2+(y-y_0)^2+(z-z_0)^2=25[/tex]
The general equation of a sphere is (x - a)² + (y - b)² + (z - c)² = r², where (a, b, c) denotes the center of the sphere and r represents the radius .
So, [tex](x-x_0)^2+(y-y_0)^2+(z-z_0)^2=25[/tex] represents a sphere with center as [tex]\left ( x_0,y_0,z_0 \right )[/tex] and radius equal to 5 units
