The height of the water decreases at a rate of 0.012 ft/sec if a cylindrical tank of a radius of 2.5 feet is being drained of water at a rate of 0.25 ft³/sec.
What is a cylinder?In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.
We know the volume of the cylinder is given by:
[tex]\rm V = \pi r^2 h[/tex]
It is given that:
A cylindrical tank of a radius of 2.5 feet is being drained of water at a rate of 0.25 ft³/sec
As we know,
The volume of the cylinder is given by:
V = πr²h
Let V is the water draining rate
V = 0.25 ft³/sec
The radius r = 2.5 feet
0.25 ft³/sec = π(2.5 feet)²(h)
h = [0.25/(2.5²π)] [ft³/(sec×feet²]
h = 0.012 ft/sec
Thus, the height of the water decreases at a rate of 0.012 ft/sec if a cylindrical tank of a radius of 2.5 feet is being drained of water at a rate of 0.25 ft³/sec.

-8x + y = -16
-3x + y = -5
Answer:
x= 11/3
y= 6
Step-by-step explanation:
-8x+y=-16
-3x+y = - 5
Multiply the second equation by -1, we get,
-8x + y = -16
3x -y = 5
--------------------
-3x = -11
x= 11/3
x=11/3. so,
-3×11/3 +y = -5
-11+y=-5
y= -5+11
y=6

Answer:
The median is 5
Step-by-step explanation:
The median is the value that is in the middle of a data set. One can find this value by lining up all of the values in the data set in ascending order (from smallest to largest). Then one will cross out answers on either side of the data set until one is left with a single value. In the event that one is left with two values, one will take the average of the two values. In other words, add the two values and then divide the result by 2.
The first step in finding the median is to list out all of the given data. Transcribe the visual data that is given in the problem into numerical data. In other words, rewrite the numbers represented by the dots as actual numbers.
1, 1, 3, 4, 4, 5, 6, 6, 6, 7, 9
Now take out numbers from each side until a single number is left in the middle.
1, 1, 3, 4, 4, 5, 6, 6, 6, 7, 9
1, 3, 4, 4, 5, 6, 6, 6, 7

Solve for the two variables in the following system of equations. 7x-8y=-12
--4x+2y=3
Answer:
x=0, y=3/2. (0, 3/2).
Step-by-step explanation:
7x-8y=-12
-4x+2y=3
----------------
7x-8y=-12
4(-4x+2y)=4(3)
-----------------------
7x-8y=-12
-16x+8y=12
----------------
-9x=0
x=0/-9
x=0
7(0)-8y=-12
0-8y=-12
8y=0-(-12)
8y=0+12
8y=12
y=12/8
simplify
y=3/2

A tank is draining water such that the volume is given which an exponentially decreasing graph as shown in the graph below. If the volume was modeled with an equation of the form V=a(b)^t, where t is the number of hours then which of the following is the best value for b?
(1) b=20
(2) b=0.6
(3) b=2.8
(4) b=0.3
Answer:
[tex]b = 0.3[/tex]
Step-by-step explanation:
Given
[tex]V = ab^t[/tex]
See attachment for graph
From the graph
V = 20 when t = 0
This implies that:
[tex]V = ab^t[/tex]
[tex]20 = ab^0[/tex]
[tex]20 = a * 1[/tex]
[tex]20 = a[/tex]
[tex]a = 20[/tex]
Also:
V = 4 when t = 1.5
So:
[tex]4 = ab^{1.5[/tex]
Substitute 20 for a
[tex]4 = 20 * b^{1.5[/tex]
Divide by 20
[tex]0.2 =b^{1.5[/tex]
[tex]b^{1.5} = 0.2[/tex]
Take 1.5th root of both sides
[tex]b = 0.34199518933[/tex]
[tex]b = 0.3[/tex] --- approximated

It takes 1/2 of a cup of flour to make a batch of pancakes, Curtis has 5 cups of flour.
How many batches of pancakes can he make?
Answer:
10 Batches
2 halfs make a whole therefore every cup would count as 2 batches
using this we can multiply 5 by 2 to get 10 batches.
The number of batches of pancakes Curtis can make is A = 10 batches
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
If Curtis takes 1/2 cup of flour to make a batch of pancakes, then the number of batches of pancakes that can be made from 5 cups of flour is:
5 cups / (1/2 cup per batch) = 5 / 0.5
On simplifying the equation , we get
A = 10 batches
Therefore, Curtis can make 10 batches of pancakes with 5 cups of flour
Hence , the number of batches is 10

A large van is being used for a picnic. There will be 8 people riding in the van, and there are 8 seats in the van (one of which is the driver's seat). One of the 8 people will have to drive, but only 4 of the people are licensed to drive the van. In how many different ways could the people seat themselves in the van so that they have a licensed driver
Answer:
The people can seat themselves in 20160 different ways.
Step-by-step explanation:
Arrangements of n elements:
The number of arrangements of n elements is given by the following formula:
[tex]A_{n} = n![/tex]
In this question:
For the first seat, that is, the driver seat, 4 possible people can sit.
For the remaining 7 seats, the number of ways in which the people can sit is an arrangement of 7 elements. So
[tex]T = 4*7! = 4*5040 = 20160[/tex]
The people can seat themselves in 20160 different ways.
