The difference between 4 x 3 and 43 is that 4 x 3 is the mathematical operation of multiplying 4 and 3, which equals 12, while 43 is just a number.
The Mathematical OperationsThe difference between the expression "4 times 3" and the number 43 is that the former indicates the mathematical action of multiplying "4 times 3," which results in the value 12, while the latter simply represents the number itself.
To prove this, you can perform the mathematical operation of 4 x 3 = 12 and compare it to the number 43. As 12 is not equal to 43, it is clear that these are two different values.
In general, when we see a number with multiple digits, like 43, it is generally not thought of as the result of a mathematical operation. However, when we see an expression like 4 x 3, we know that it is the result of a multiplication operation and it is not just a number.

Your cla had an ant farm with 32 ant. If the number of ant increaed by a factor of 5 every week, how many ant would there be after 3 week? Write your anwer in numerical form
The ant population increases by factor of 5 every week. After 3 weeks, there will be 800 ants in the farm.
The problem can be solved by considering the ant population growth as a geometric sequence.
In a geometric sequence, a term is obtained by multiplying the previous term by a constant, which is called a common ratio. We can consider this common ratio as a growth factor.
In this case, the common ratio = 5
week 1 = 32 ants
week 2 = 32 x 5 ants = 160 ants
week 3 = 160 x 5 ants = 800 ants
We can also find the number of ants using the geometric sequence formula for the nth term:
a(n) = a . rⁿ⁻¹
Where:
a = first term = 32
r = common ratio = 5
Hence,
a(3) = 32 x 5² = 800 ants

Max's dad bought his friends 5 bottles of water and 8 slices of pizza at the concession stand and spent $20.25. He had to go back and get 1 more bottle of water and 3 slices of pizza. This time the total was $6.50. What is the cost of one slice of pizza?
Step by step explanation please?!
Using simultaneous equations, the cost of one slice of pizza bought by Max's dad at the concession stand is $1.75.
What are simultaneous equations?Simultaneous equations are two or more equations solved concurrently or simultaneously.
Simultaneous equations are also called a system of equations.
Bottles Slices of Total
of Water Pizza Cost
1st purchase 5 8 $20.25
2nd purchase 1 3 $6.50
Let the cost of bottles of water = b and the cost of slices of pizza = p
Equations:Equation 1: 5b + 8p = 20.25
Equation 2: b + 3p = 6.50
Multiply Equation 2 by 5:
Equation 3: 5b + 15p = 32.50
Subtract Equation 1 from Equation 3:
5b + 15p = 32.50
-
5b + 8p = 20.25
7p = 12.25
p = 1.75
The cost of one slice of pizza (p) = $1.75
Check:
b + 3p = 6.50
b + 3(1.75) = 6.50
b + 5.25 = 6.50
b = 1.25
= $1.25

According to estimates, there were 7,060,268,214 people on Earth as of August 16, 2012. Rounding to the nearest hundred million, 7,060,268,214 equals 7,100,000,000.
How do you round to the nearest hundred million?Find the digit that is 100,000,000 places away first. The next step is to check if the number that comes after the hundred million place is 5 or higher. Next, multiply the result by 100 million to the nearest billion. 200,000,000 is the reply. 4,000,000 or 5,000,000 may be the million closest to you.
Take a glance at the number in the right-hand column, the hundred thousands, to determine the nearest million. 5 appears in the column for "hundred thousands." It is standard practise to round up numbers that are five or more. This means that you should look at the digit in the ten thousand spot to round numbers out to the nearest hundred thousand. 1,000,000 is added as a rounding error.

Given the point (10,5) and the perpendicular line y = 1/2x - 4, write the equation of a line.
The linear equation perpendicular to the line y = 1/2x - 4 is:
y = -2x + 25
How to find the linear function?A general linear equation can be written as:
y = m*x + b
Where m is the slope and b is the y-intercept.
And two lines are perpendicular if the product between the slopes is -1, then if we want to find a line perpendicular to:
y = 1/2x - 4
Then the slope m must be sch that:
m*(1/2) = -1
m = -2
Then the line is like:
y = -2*x + b
And we know that this passes through (10, 5), replacing these values:
5 = -2*10 + b
5 = -20 + b
5 + 20 = b

The average price of a gallon of milk was $2.78 in 2000 and increased by about $0.11 per year. Write an inequality that could be used to determine the years, y, in which the price of a gallon of milk is between 3 and 4 dollars.
We know that the average price of a gallon of milk in 2000 was $2.78 and that it increased by about $0.11 per year. To find the years in which the price of a gallon of milk is between $3 and $4, we can use the following inequality:
2.78 + 0.11y < x < 4
Where x is the price of a gallon of milk in a given year y, and y represents the number of years since 2000.
The inequality can also be written as:
2.78 + 0.11y < x < 4
That can be simplified as
y > (3-2.78) / 0.11 = (0.22) / 0.11 = 2
y < (4-2.78) / 0.11 = (1.22) / 0.11 = 11
So, the years in which the price of a gallon of milk is between $3 and $4 are y > 2 and y < 11

Amount paid by each student = Rs.45765 / 150 = Rs.305
The school contributed an extra 1.7%. for the payment order on top of the registration fee of Rs. 45000.
To find the total amount paid by the school, we need to calculate the additional amount and add it to the registration fee:
Additional amount = (1.7/100) * 45000 = Rs. 765
Total amount paid by the school = registration fee + additional amount = 45000 + 765 = Rs.45765
To find the amount paid by each student, we need to divide the total amount paid by the school by the number of students:

The Biquadratic equation is given as : x⁴ - 5x² - 14 = 0 ;
to change the given equation to a quadratic equation ,
we substitute x⁴ = y² and x² = y .....equation(1)
the quadratic equation becomes as : y² - 5y - 14 = 0;
Now, we observe that to factor this expression, we find the two number whose product is 14 and whose difference is 5, such numbers are 7 and 2.
that means ⇒ y² - 5y - 14 = (y - 7)(y + 2);
from equation(1) ,
we get ; ⇒ x⁴ - 5x² - 14 = (x² - 7)(x² + 2) = 0;

You want a function that describes the value of a $900 sound system that decreases in value by 9% per year.
Exponential functionWhen the amount of change is proportional to the amount, the amount is described by an exponential function:
y = ab^x
where 'a' is the initial value, and 'b' is the "growth factor."
ApplicationHere, the change is expressed as a "growth rate" of -9% per year. The growth factor is 1 added to the growth rate:
b = 1 +(-9%) = 1 -0.09 = 0.91
The initial value is given as ...

any negative exponent of 1.3 means we have to consider it as 1/1.3 with the positive exponent.
so, if the given temperature (x) is negative, 1.3 has a positive exponent and gets bigger and bigger the lower (smaller) x gets.
if the given temperature (x) is positive, 1.3 has a negative exponent and gets smaller and smaller the higher (bigger) x gets.
the domain is the interval or set of all valid x-values.
there is no need for any restriction for x.
so, the domain is all real numbers.
the question is : up to what temperature will there be heating ?
at 5°C ? yes, sure.
at 10°C ? yes, sure.
at 15°C ? some people still need heating.
at 20°C ? most likely not.
but f(20) = $0.042094266... ≈ $0.04
so, still a tiny little bit of heating is happening for the function, but in reality most likely not at all.
the information about such a limit is missing in the question. so, again no limit for x.
f(-8) means that x = -8.
f(-8) = 8(1.3)^--8 = 8(1.3)⁸ = 8×8.15730721 =

what are the next five terms and conjuncture of 1, 8, 27, 64
Answer:
125, 216, 343, 512
Step-by-step explanation:
The next number in the sequence 1, 8, 27, 64 is 125.
This sequence follows the pattern of starting with the number 1, then finding the cube of each subsequent integer (the cube of a number is found by multiplying the number by itself twice, so the cube of 2 is 222=8). Therefore, the next number in the sequence would be 555=125.

What is the solution to an equation?
In order to make the equation's equality true, the unknown variables must be given values as a solution. In other words, the definition of a solution is a value or set of values (one for each unknown) that, when used as a replacement for the unknowns, transforms the equation into equality.
Vertical angles are equal
2x+1=53
=> 2x=53-1 = 52
x=52/2 = 26 degrees
similarly,
5x+1=66
=> 5x=66-1 = 65
=> x=65/5 = 13 degrees
