The Sumerians were different from other people of their time as they wee more advanced.
Who were the Sumerians?The Sumerians were a southern Mesopotamian people whose civilisation flourished between approximately 4100 and 1750 BCE. Sumer was an ancient civilization that flourished in the Fertile Crescent region of Mesopotamia, between the Tigris and Euphrates rivers. Sumerians are regarded as the creators of civilisation as we know it today, according to their advancements in language, governance, building, and other fields.
They were able to take technologies produced elsewhere and use them on a far larger scale. This allowed them to mass-produce commodities such as textiles and pottery, which they could subsequently trade with others.

the difference of t and five multiplied by six is four
Answers
The expression of the mathematical statement given as the difference of t and five multiplied by six is four is 6(t - 5) = 4
How to express the mathematical statement as an expression?From the question, the mathematical statement is given as
the difference of t and five multiplied by six is four
The difference of numbers means that we subtract the numbers
i.e. difference means subtraction
So, we have
the difference of t and five multiplied by six is four ⇒ (t - five) multiplied by six is four
The multiplication of numbers means that we take the product of the numbers
i.e. multiply means product
So, we have
the difference of t and five multiplied by six is four ⇒ (t - five) x six is four
Lastly, we have
(t - five) x six = four
Express as numbers
(t - 5) x 6 = 4
This becomes
6(t - 5) = 4
Hence, the expression represented by the statement is 6(t - 5) = 4

how do I simplify it to find the determinant in an easy way

The determinant of the given matrix is [tex]2a^4bc+2c^4ab+6a^3b^2c+6a^3bc^2+6c^3ab^2+6a^2b^3c+12a^2b^2c^2+6a^2c^3b+6c^2ab^3+2acb^4[/tex]
Determinant of the matrix:
Determinant of the matrix is defined as a scalar value which is associated with the square matrix.
Given,
Here we have the matrix show in the question.
Now, we need to find the determinant of the matrix.
To find the determinant of the matrix we have to do the following steps:
1) First we have to pick any row or column in the matrix. It does not matter which row or which column you use, the answer will be the same for any row or column.
2) After the selection you have to multiply every element in that row or column by its cofactor and add. The result is the determinant.
This process can be elaborated in the following steps:
[tex]=(b+c)^2 \times ((a+c)^2 \times (a+b)^2 - b^2 \times c^2) -a^2 \times (b^2 \times (a+b)^2 - b^2 \times c^2) +a^2 \times (b^2 \times c^2 - (a+c)^2 \times c^2)[/tex]
When we expand the equation then we get,
[tex]=(b+c)^2 \times (a^4+2a^3b+2a^3c+a^2b^2+4a^2cb+c^2a^2+2c^2ab+c^2b^2+2acb^2 -b^2c^2) -a^2 \times(b^4+2b^3a+b^2a^2 -b^2c^2) +a^2 \times(b^2c^2 -c^4-2c^3a-c^2a^2)[/tex]
Group the similar terms and arrange them in order,
[tex]=(b+c)^2 \times (a^4+2a^3b+2a^3c+a^2b^2+4a^2cb+c^2a^2+2c^2ab+2acb^2) -a^2 \times (b^4+2b^3a+b^2a^2-b^2c^2) +a^2 \times (-c^4-2c^3a+b^2c^2-c^2a^2)[/tex]
Again we have to expand it and then we get,
[tex]= a^4b^2+2a^4bc+a^4c^2+c^4a^2+2c^4ab+2a^3b^3+6a^3b^2c+6a^3bc^2+2a^3c^3+6c^3ab^2+a^2b^4+6a^2b^3c+10a^2b^2c^2+6a^2c^3b+6c^2ab^3+2acb^4 -b^4a^2-2b^3a^3-b^2a^4+b^2c^2a^2 -c^4a^2-2c^3a^3+b^2c^2a^2-c^2a^4[/tex]
After the simplification, the resulting determinant is
[tex]=2a^4bc+2c^4ab+6a^3b^2c+6a^3bc^2+6c^3ab^2+6a^2b^3c+12a^2b^2c^2+6a^2c^3b+6c^2ab^3+2acb^4[/tex]

Calculate the area of the

Answers
Answer :- 60 cm^2
Step-by-Step Solution :-
Let ABCD be the Rectangle.
Given :
AD = 12 cm
BD = 13 cm
To Find : Area of ABCD
Solution :
In ∆ADB,
AD = 12 cm and BD = 13 cm
By Pythagoras Theorem,
(BD)^2 = (AD)^2 + (AB)^2
13^2 = 12^2 + (AB)^2
169 = 144 + (AB)^2
AB^2 = 169 - 144 = 25
AB = √25
Therefore, AB = 5 cm
Now, to find the Area,
Area of Rectangle = length × breadth
Area of ABCD = 12 × 5
Therefore, Area of ABCD = 60 cm^2

The average speed of this particle over the interval 2 ≤ t ≤ 10 is 25 , the correct option is (b)25 .
In the question ,
it is given that
the position of the particle that travels along the x-axis at time t is given by the function
x(t)=2t²+t
the average speed of the particle can be calculated by using the formula
average speed = (change is distance)/(change in time)
particle position at t=2
x(2) = 2(2)²+2 = 2*4+2 = 10
particle position at t=10
x(10) = 2(10)²+(10)
= 2*100+10
= 200+10
= 210
So, change in distance = 210-10= 200
change in time = 10-2 = 8
Putting the values in the average speed formula we get
average speed = 200/8
= 100/4

Step-by-step explanation:
The flat rate is the base, in which no matter how long you rent it for, they'll still charge you that much. You have 200 dollars, and negative 75 is 125 dollars, which you can spend on the hours. Assuming you can rent the jet ski for half an hour, you can divide 125 by 10 for the amount of hours, and the answer is 12.5 hours. However, if you can't rent the jet skis for half an hour, the answer is 12 hours.
