9. The diagram shows a triangle inscribed in a circle with centre O.
The lengths of the shorter sides of the triangle are 6 cm and 8 cm.
Work out the area of the circle.
Use π = 3.14.​

Answers

Answer:

25π

Step-by-step explanation:

let c = length of third side of triangle

since you are working with a right triangle you can find the third side by using the pythagorean theorem:  8^2 + 6^2 = c^2

64 + 36 = c^2

100 = c^2

c = 10

10 is also the diameter of the circle and radius is 5

A = π · r²

Answer:

  see the attachment

Step-by-step explanation:

There are no roots, fractional powers, or denominators containing variables, so each of these expressions is the sum of multiples of products of variables to integer powers. (One is a constant.) That makes each expression a polynomial. Some polynomials can be further classified by their degree.

The degree is the highest sum of powers of the variables in the terms. For example, the term a^2·b·c^2 has variables with powers 2, 1, and 2. The sum of those powers is 2+1+2 = 5, so this is a term of degree 5.

A constant is a term with no variables.

__

It is customary in algebra problems to use variables that are a single lower-case letter. Sometimes, a variable may be represented by a letter in uppercase, or in a special font or language (usually Greek). Sometimes, it may be a word or phrase. Here, we assume each variable is one letter, so xyz is the product of three variables.

Perhaps the table below answers the questions you are asking about these expressions.

Step-by-step explanation:  You can order without knowing the areas because of the size

Answer:

From Left to Right:

Large, Medium, Small

Explanation:

Assuming all the numbers are the same (chances are that they are seeing as they use the same variable ((the Greek lowercase letter known as Psi - Ψ)), then we should determine the area based on formulas.For the leftmost shape, you have to use the length * width formula TWICE and then subtract the missing area value to find the remaining area (which is--even after subtracting, the greatest than out of all the other shapes).For the middle shape, the formula you use is length * width-- which is less than that of the leftmost shape, but more than the rightmost shape.For the rightmost shape, the formula you use is (length * width)/2--which is half of the middle shape and less than the largest shape.

Answer:

Step - by - step explanation :

[tex] \underline{ \underline{ \sf{Solution}}} : [/tex]

USING ELIMINATION METHOD :

[tex] \sf{ - 3x - 9y = - 12}[/tex] ••••••• equation ( i )

[tex] \sf{ - 3x + 7y = 4}[/tex] ••••••• equation ( ii )

Subtracting equation ( ii ) from ( i )

Note that while subtracting equation ( ii ) from ( i ) , sign of each term of equation ( ii ) changes and hence becomes 3x - 7y = -4.

[tex] \sf{ \cancel{ - 3x} - 9y = - 12}[/tex]

[tex] \sf{ \cancel{3x} - 7y = - 4}[/tex]

_____________________

➺ [tex] \sf{ - 16y = - 16}[/tex]

➺ [tex] \sf{ \frac{ - 16y}{ - 16} = \frac{ - 16}{ - 16}} [/tex]

➺ [tex] \sf{y = 1}[/tex]

The value of y is 1. Since , we are asked to find the value of x , substituting the value of y in equation ( i) , we get :

➺ [tex] \sf{ - 3x - 9 \times 1 = - 12}[/tex]

➺ [tex] \sf{ - 3x - 9 = - 12}[/tex]

➺ [tex] \sf{ - 3x = - 12 + 9}[/tex]

➺ [tex] \sf{ - 3x = - 3}[/tex]

➺ [tex] \sf{ \frac{ - 3x}{ - 3} = \frac{ - 3}{ - 3}} [/tex]

➺ [tex] \sf{ x = \boxed{ \bold{ \red{ \sf{1}}}}}[/tex]

Hence , the value of x is 1 .

There are many methods to solve such simultaneous equations. They are :

Graphical method : In this method , we find a few pairs of solutions to each of two given equations. The pairs of solutions of each equation are plotted in a graph and by joining them, two separate straight line lines are obtained. The coordinates of the point of intersection of two straight lines are the solutions to the given equation.

Elimination method : In this method, we add or subtract the given equations to eliminate one of the two variable by making their coefficients equal. Then , a single equation with one variable so obtained is solved to find the value of the variable. The value of the variable is substituted to any one equation to find the value of the eliminated variable.

Substitution method : In this method , a variable is expressed in terms of another variable from one equation and it is substituted in the remaining equations.

What is the largest 2-digit composite number divisible by 46? ​

Answers

Answer:

92

Step-by-step explanation:

its 92 because its is a 2-digit number and is considered composite because its divisible by 2, 4, 23 and 46

The largest 2-digit composite number divisible by 46 is 92 and this can be determined by using the definition of composite numbers and by arithmetic operations.

Given :

Number - 46

The following steps can be used to determine the largest 2-digit composite number divisible by 46:

Step 1 - Remember that composite numbers are those numbers that are divisible by more than two numbers.

Step 2 - The two-digit composite numbers which are divisible by 46 are 46 and 92.

Step 3 - The largest number between 46 and 92 is 92.

So, the largest 2-digit composite number divisible by 46 is 92.

-5x+7y=-34
-5x+3y=-6

Answers

Answer:

        x = -3,  y = -7

Step-by-step explanation:

-5x + 7y = -34     ⇒  -5x = -34  - 7y

    -5x + 3y = -6

-34  - 7y + 3y = -6

-34 - 4y = -6          {add 34 to both sides}

  -4y = 28             {divide both sides by (-4)}

     y = - 7

-5x + 3y = -6

-5x + 3(-7) = -6

-5x - 21 = -6        {add 21 to both sides}

-5x = 15            {divide both sides by (-5)}

  x = -3

Step 2: Add x to both sides.
