Answer:

Step-by-step explanation:

To find the sum of an interior angle of a polygon, you have to follow these steps:

Interior angle= ( n - 2 ) ×180° all over n

So interior = ( 32 - 2 ) × 180° all over 32

Interior = 30 × 180 all over 32

Therefore your interior angle should be 168.75°

Answer:

i)  (x -y) -y  = 11

ii) (x+y) + x² = 8

iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation   x² + y² = 25

Step-by-step explanation:

Step(i):-

Given that x =3 and y=-4

i)  (x -y) -y = (3-(-4))-(-4) = 3+4+4 = 11

ii) (x+y) + x² = ( 3 -4) + (3)² = -1 + 9 = 8

Step(ii):-

Given equation  

                    x² + y² = 25

we can choose (x,y) = ( 3 , -4)

                 3²+(-4)² = 25

                     25    = 25

The ordered pair ( 3,-4) satisfies the equation

second ordered pair ( 3 ,4)

                        x² + y² = 25

                       9 + 16 = 25

                           25 = 25

Final answer:-

i)  (x -y) -y  = 11

ii) (x+y) + x² = 8

iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation   x² + y² = 25

Answer:

There are no simple factors to this expression.  You can however solve for x, giving you:

x = -1 ± √(y + 3)

Step-by-step explanation:

There is no simple pair of factors to this equation, so we'll have to go through the full process.  You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2.  We can however solve for x:

[tex]y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}[/tex]

Answer:

Find the exact value using trigonometric identities.

Exact Form: x=34

Decimal Form: x=0.75

Step-by-step explanation:

The value of x is 3.

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.

Given:

[tex]9^{-1/2} = 27^{1/4}[/tex]÷[tex]3^{x +1}[/tex]

[tex][3^{2}]^{{-1/2}} = [(3)^{4}]^{1/4}[/tex] ÷[tex]3^{x +1}[/tex]

[tex]3^{-1}[/tex] = 3 ÷[tex]3^{x +1}[/tex]

[tex]3^{-1}[/tex]= [tex]\frac{3}{3^{x+1}}[/tex]

[tex]3^{-1}= 3^{1-x+1}[/tex]

[tex]3^{-1}= 3^{2-x}[/tex]

On comparing we get,

-1=2-x

x= 3

Hence, the value of x is 3.

Answer:

Rs 64000

Step-by-step explanation:

Since breadth B = 80% of length L, B = 0.8L

Perimeter, P = 2(L + B) = 360m

Substituting B = 0.8L into P, we have

2(0.8L + L) = 360 m

2(1.8L) = 360 m

3.6L = 360 m

L = 360m/3.6

L = 100 m

So, B = 0.8L = 0.8(100 m) = 80 m

The area of the rectangular ground is A = LB = 100 m × 80 m = 8000 m²

So, the cost of planting the ground at Rs 8 per m² is  Rs 8 per m² × 8000 m² = Rs 64000

Answer:

  $25

Step-by-step explanation:

Let p represent the monthly payment. There are 5 of them, so the amount of their total is 5p. That, together with the down payment, makes up the entire cost of the system.

  5p +25 = 150 . . . . an equation representing the relationships

__

To solve this, subtract 25 and divide by 5.

  5p = 125

  p = 125/5 = 25

Each monthly payment is $25.

Answer:

Hello again! Your answer would be B and D

Step-by-step explanation:

A square is a shape with 4 sides and all of them have to equal. Right away you can see that D is without needing to look at it. You might think that B is not because of its angle but if you turn your paper/computer to the side a bit you can there see that it is square. C and A are not because of their unequal sides. Yes, they do have four sides but they are non-equal.

Answer: Displacement=12 m north

Step-by-step explanation:

12 m north

Let’s assume

north= positive

south=negative

12+(-16)+22+(-6)=12

Answer:

It is positive (9)

Step-by-step explanation:

Negative ÷ negative = positive

Negative ÷ positive = negative

positive ÷ positive = positive

positive ÷ negative = negative

Negative × negative = positive

negative × positive = negative

positive × positive = positive

Positive × negative = negative

If both symbols are the same, it is positive. If one is positive and one is negative (different symbols), it is negative.

The result is 9. Since both the divisor (-3) and the dividend (-27) are negative, the final result is positive.

When dividing -27 by -3, the result is positive. In this case, the negative signs cancel out each other, and two negatives make a positive.

To understand why, think of division as the process of finding out how many times one number (divisor) can fit into another number (dividend). In this case, we are trying to find out how many times -3 can fit into -27.

-27 ÷ (-3) = 9

Here's the step-by-step calculation: -3 times 9 equals -27, which matches the dividend. So, the result is 9.

Since both the divisor (-3) and the dividend (-27) are negative, the final result is positive.

In conclusion, -27 divided by -3 is positive 9.

Answer:

What is the Riemann hypothesis simply explained?

The Riemann hypothesis asks if every non-trivial root (white dot) would be on the line down the middle. If the answer is no, we say the "hypothesis is false". This would mean that there are white dots which are not on the line given.
