9) LCM = 36; GCF = 3
10) LCM = 108; GCF = 6
11) LCM = 48; GCF = 4
Explanation:
9)
36 = 2 x 2 x 3 x 3 = 2² x 3²
3 = 3
12 = 2 x 2 x 3 = 2² x 3
LCM = 2 x 2 x 3 x 3 = 36
GCF = 3
10)
6 = 2 x 3
54 = 2 x 3 x 3 x 3 = 2 x 3³
12 = 2 x 2 x 3 = 2² x 3
LCM = 2 x 2 x 3 x 3 x 3 = 108
GCF = 2 x 3 = 6
11)
16 = 2 x 2 x 2 x 2 = 2⁴
8 = 2 x 2 x 2 = 2³
12 = 2 x 2 x 3 = 2² x 3
LCM = 2 x 2 x 2 x 2 x 3 = 48
GCF = 2 x 2 = 4

1. A cone-shaped filter has a diameter of 10 inches and a height of 4 inches.
What is the volume of liquid the filter can hold? Round your answer to
the nearest hundredth.
Answers
The volume of liquid contained by cone is 105 inches cube.
What is volume?
It can be defined as the total content which can be held inside a container.
Main body:
the volume of a cone = [tex]\frac{1}{3}\pi r^{2} h[/tex] , where r = radius and h = height of cone
diameter = 10 , so radius = d/2 = 5 inches
V = [tex]\frac{1}{3}\pi 5*5*4[/tex]
V = 3.14 *5*5*4*1/3
v≈105 inches cube
Hence the volume is 105 inches cube.

the side length of a square is √8 find the area.
is the number rational or irrational?
Answers
The area of a square with a side length √8 represents a rational number, which is equal to 8 square units.
Is the number behind the area of the square a rational number?
Rational numbers are real numbers of the form m / n, where m and n are integers, where n ≠ 0. The rest of real numbers are irrational (i.e. π, √5, ∛7, e) Besides, the area of the square is determined by the following formula:
A = l²
Where l is the side length of the square.
First, substitute the side length of the square in the area formula:
A = (√8)²
Second, use algebraic properties to simplify the expression and find the corresponding result:
A = ([tex]8^{\frac{1}{2} }[/tex])²
A = 8
This number represents a rational number as 8 is equivalent to the rational number 8 / 1.

A couple bought a rental house for $195,000 it’s assessed value was $180,000 if the tax rate is $1.50 per $100 of assessed value what is the monthly contribution the lender will require for taxes round to the nearest cent
Answers
Step-by-step explanation:
there is no interest and such involved. it is a straight forward calculation to allow the lender to accumulate enough funds (= the ESCROW account as part of the mortgage account structure) to be able to pay the taxes once a year on behalf of the owners.
so, the tax is $1.50 for every $100 of the assessed value of the house.
how many $100 units are in that value ?
180,000 / 100 = 1,800 units.
that means the tax for that house is
1800 × 1.5 = $2,700
in order for the lender to accumulate $2,700 in the ESCROW account in a year (= 12 months), the monthly contribution has to be
2700 / 12 = $225.00
A model rocket is launched with an initial upward velocity of 235 feet the Rockets height H in feet after t seconds is given by the following
Answers
By assuming that the initial height of the rocket is the ground, we will get the height equation:
H(t) = -16*t^2 + 235*t
How to find the equation for the height?The height equation for any object near the surface of the heart that is not being subject to any other forces than the gravitational one is:
H(t) = -16*t^2 + v*t + h
Where:
t represents the time in seconds.
the first coefficient -16 is half of the gravitational acceleration in feet over squared seconds.
v is the initial velocity, which in this case is 235 ft/s
h is the initial height, in this case we assume is zero (the rocket is launched from the ground)
Replacing all that in the height equation, we will get:
H(t) = -16*t^2 + 235*t

Step; 2. 3^x = 27; This step is correct because she got it by using division property of equality to divide both sides by 7.
Step 3; log^3 (^3) = log^27; This step is incorrect because from basic rules of logarithm, we know that; log 3^x = x log 3
Step 4. xlog^33=9; This is incorrect because you cannot remove the log on one side of the equation without doing the same on the second side. Thus, what she she should have had here is;

Inflation causes things to cost more, and for our money to buy less (hence your grandparents saying "In my day, you could buy a cup of coffee for a nickel"). Suppose inflation decreases the value of money by 4% each year. In other words, if you have $1 this year, next year it will only buy you $0.96 worth of stuff. How much will $100 buy you in 20 years?
Answers
The amount that $100 will be able to buy in 20 years, given an inflation rate of 4% is $44.20
How to find the value of money?When given the inflation rate, know that this rate is the rate at which the value of money decreases per year.
If given a rate of 4% as inflation, then the value of a dollar would decrease by 4% a year.
In 20 years therefore, the value of $100 would be:
Value in 20 years = Value today x (1 - inflation rate) ^ number of years
= 100 x (1 - 4%) ²⁰
= $44.20

A hexagon has exterior angle measures of (7n + 3), (10n-17)°,
(8n - 16), (4n+17), (-n + 16), and (5n - 6)°.
Find the value of n.
Answers
Using the sum of exterior angle, the value of n is 11.
In the given question,
A hexagon has exterior angle measures of (7n + 3), (10n-17), (8n - 16), (4n+17), (-n + 16), and (5n - 6)°.
We have to find the value of n.
As we know that the sum of exterior angle of any polygon is equal to 360°.
As the given measures are (7n + 3), (10n-17), (8n - 16), (4n+17), (-n + 16), and (5n - 6)°.
So we can find the value of n by adding the all measures.
So the expression should be
(7n + 3) + (10n-17) + (8n - 16) + (4n+17) + (-n + 16) + (5n - 6)° = 360°
Simplifying the bracket.
7n + 3 + 10n-17 + 8n - 16 + 4n+17 - n + 16 + 5n - 6 = 360°
Solving the expression by solving the same term
(7n+10n+8n+4n-n+5n)+(3-17-16+17+16-6)= 360°
33n-3 = 360°
Add 3 on both side
33n-3+3 = 360°+3
33n = 357°
Divide by 33 on both side
33/33 n= 363°/33
n = 11
Hence, the value of n is 11.

Subtraction serves as a representation for the act of removing items from a collection. The minus sign stands for subtraction. For example, if four of the nine oranges that are stacked together (as in the above figure) are then moved to a basket, the stack will now contain five oranges rather than nine. Therefore, the difference between 9 and 4 is 5, or equals 9 minus 4. In addition to applying it to natural numbers, subtraction can also be used with other kinds of numbers. The letter "-" represents subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation.

The length of a rectangle is 6 m longer than its width. If the perimeter of the rectangle is 64 m find its length and width in meters
Answers
The length and width of the rectangle with a perimeter of 64m are 19m and 13m respectively.
What is the length and width of the rectangle?The perimeter of a rectangle is expressed as;
P = 2( l + w )
Where l is length and w is width.
Given the data in the question;
Let x represent the width be represented by variable x.
Width w = xLength l = x + 6Perimeter = 64Plug the values into the equation above above.
P = 2( l + w )
64 = 2( (x + 6 ) + x )
64 = 2( 2x + 6 )
64 = 4x + 12
64 - 12 = 4x
52 = 4x
x = 52/4
x = 13
Hence, the dimensions of the rectangle are;
Width = x = 13m
Length = x + 6 = 13 + 6 = 19m
Therefore, the dimension of the rectangle are 13m by 19m.

Add x² to both sides :
x² + y = 100
Subtract y from both sides :
