use six unit multipliers to convert 33 cubic feet to cubic centimeters
Converting 33 cubic feet to cubic centimeters would give 934454. 4 cubic centimeters
How to determine the conversionIt is important to note that conversion of units requires the appropriate equivalent values
For
I cubic foot is equivalent to 28316. 8 cubic centimeters
But we were given
33 cubic feet for the conversion
If 1 cubic foot = 28316. 8 cubic centimeters
Then 33 cubic feet = x
Cross multiply, we get
x = 28316. 8 × 33
x = 934454. 4 cubic centimeters
Thus, converting 33 cubic feet to cubic centimeters would give 934454. 4 cubic centimeters

A container is the shape of an inverted right circular cone has a radius of 4.00 inches at the top and a height of 5.00 inches. At the instant when the water in the container is 2.00 inches deep, the surface level is falling at the rate of -2.00 in./s. Find the rate at which water is being drained.
The rate at which the water from the container is being drained is 24 inches per second.
Given radius of right circular cone 4 inches .height being 5 inches, height of water is 2 inches and rate at which surface area is falling is 2 inches per second.
Looking at the image we can use similar triangle propert to derive the relationship:
r/R=h/H
where dh/dt=2.
Thus r/5=2/5
r=2 inches
Now from r/R=h/H
we have to write with initial values of cone and differentiate:
r/5=h/5
5r=5h
differentiating with respect to t
5 dr/dt=5 dh/dt
dh/dt is given as 2
5 dr/dt=5*-2
dr/dt=-2
Volume of cone is 1/3 π[tex]r^{2} h[/tex]
We can find the rate at which the water is to be drained by using partial differentiation on the volume equation.
Thus
dv/dt=1/3 π(2rh*dr/dt)+([tex]r^{2}[/tex]*dh/dt)
Putting the values which are given and calculated we get
dv/dt=1/3π(2*2*2*2)+(4*2)
=1/3*3.14*(16+8)
=3.14*24/3.14
=24 inches per second
Hence the rate at which the water is drained from the container is 24 inches per second.

Javid travels to work by bus or by train.
The daily bus fare is £2.50
The daily train fare is £3.50
In 5 days he spends a total of £14.50
On how many days did he travel by bus?
Javid travelled by bus for 3 days using a simultaneous equation
What is simultaneous equation?
This refers to equations that are solved together in order to determine the values of unknown variables.
In this case, the total amount spent on daily bus or train can be determined as the fare price multiplied by the number of days
Let X be the number of days that Javid took bus
total spent on bus=2.50X
Let Y be the number of days that Javid took train
total spent on train=3.50Y
Total spent=2.50X+3.50Y
14.50=2.50X+3.50Y
Secondly, X plus Y gives 5 days
5=X+Y
multiply the second equation by 2.50 and the first by 1
14.50=2.50X+3.50Y
12.50=2.50X+2.50Y
subtract the second equation from first

The number of days that he travelled by bus is; 3 days
How to Solve Simultaneous Equations?Let x be the number of days that Javid travelled by bus.
Let y be the number of days that Javid travelled by train.
Thus;
Total spent on bus = 2.50x
Total spent on train = 3.50y
Overall total spent is;
2.5x + 3.5y = 14.50 -----(1)
Total number of days is 5 days and so;
x + y = 5 -----(2)
Making x the subject in eq 2 gives us;
x = 5 - y -----(3)
Put eq 3 in eq 1 to get;
2.5(5 - y) + 3.5y = 14.50
12.5 - 2.5y + 3.5y = 14.5
y = 14.5 - 12.5
y = 2 days

x = 5 - 2

How to determine the decreasing intervals of the function?The complete question is added as an attachment
The polynomial function f(x) is represented by the graph.
From the graph, the polynomial function decreases at (-2, 2)
The absolute function is given as;
f(x) = =5|x + 1| + 10
The vertex of the above function is
Vertex = (-1, 10)
Because a is negative (a= -5), the vertex is a maximum.
This means that the function decreases at (-1, ∞)
So, we have
(-2, 2) and (-1, ∞)

Answer:
10 just find the difference between the two
Step-by-step explanation:
16-6=10
Wangmo have 6 years of teaching experience.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Let Wangmo has x years of experience.
Jigsel has 6 more years of teaching experience than Wangmo.
So, Jigsel has x + 6 years of experience.
According to the question,
the two of them have 16 years of teaching experience altogether.
That means,
we have the equation,
(x+6) + x = 16
2x = 16 -6
2x = 10
x = 10/2
x = 5
Therefore, Wangmo has 6 years of experience.

Which of the following steps would you perform to the system of equations
below so that the equations have opposite y-coefficients?
4x+2y = 4
12X - Y = 26
A. Divide both sides of the top equation by 3
•
B. Divide both sides of the bottom equation by 3
• C. Multiply both sides of the bottom equation by 2
• D. Multiply both sides of the top equation by 2
Answer: Choice C
Multiply both sides of the bottom equation by 2
Reason:
The y coefficient of the first equation is 2. For the other equation, that y coefficient is -1. We need these coefficients to be equal but opposite. One way to do this is to double everything in the bottom equation
The bottom equation 12x-y = 26 doubles to 24x - 2y = 52
At this point we have the equivalent system of
[tex]\begin{cases}4x+2y = 4\\24x-2y = 52\end{cases}[/tex]
And we can see that we have equal but opposite y coefficients (2 and -2). The y terms add to 0 since 2y + (-2y) = 0y = 0 meaning we've eliminated y.

And a solid line that is constant of the form y = c.
We can see that the shaded region is above the constant line and below the line with a positive slope, so the system of inequalities is of the form:

The 95th percentile for the average number of residents within five miles of each store is 20219.86.
Given mean of 19000 , sample size of 75 stores and standard deviation of 7600.
We have to find the 95th percentile for the average number of residents within five miles of each store in a sample of 75 stores.
We have to first find the margin of error to calculate the upper level of confidence interval.
Margin of error is the difference between the real values and calculated values.
Margin of error=z*σ/[tex]\sqrt{n}[/tex]
where z is the critical value of z at given confidence level.
σ is standard deviation
n is the sample size.
z value at 95% confidence level is 1.39. (one tailed)
