Answer:

25 degree

Step-by-step explanation:

The sum of angles is 180

so to find angle b, subtract 155 from 180

180 - 155 = 25

b = 25 degree

5. 0384748939

Step-by-step explanation:

let's take the ramp, if u draw a diagram 8, 10 and the unknown value makes a right angled triangle

So according to pythogaraos(dnot care the spelling) theorem a square + b square = c square

Now 10 is the hypothenuse, so let's rearrange them as c square - b square = a square

now apply the values, 10 square - 8 square = X square

100 - 64 = X square

36 = X square

now root of 32 is-------

I MESSED UP I GUESS

Answer:

See under for the sequence

Step-by-step explanation:

The term with -X⁴ comes first because 4 is the highest power of x.

Then comes 7x³y³ because 3 is the second highest power

Then 2x²y⁴ because 2 comes next

Then -3xy⁵ because x is raised to 1 power which is the lowest

Answer:

[tex]\large\boxed{75.4cm(1 d.p)}[/tex]

Step-by-step explanation:

Important Information:

Circumference of a cirlce= [tex]\pi*diameter[/tex]

Diameter= [tex]2*radius[/tex]

Method:

The first step in working out the circumference of this cirlce is to work out the diameter. You can work this out by multiplying the radius of 12 by 2, this gives you 24cm. This is because the radius is half of the diameter.

The next step is to work out the circumference. You can do this by multiplying pi by the diameter of 24, this gives you [tex]27\pi[/tex] or 75.4cm (1 d.p).

Step by Step:

1) Multiply 12 by 2.

[tex]12*2=24cm[/tex]

2) Multiply pi by 24.

[tex]\pi*24=75.4cm(1 d.p)[/tex]

______________________________

Use the distributive property to multiply [tex]2x-1[/tex] by [tex]x^2+4x+3[/tex] and combine like terms:

[tex]=2x^3+7x^2+2x-3[/tex]

- So this is True.

Combine like terms and subtract 8 from 6 to get −2:

[tex]=9x^2-3x-2[/tex]

- So this is True.

Combine like terms:

[tex]=3x-2x^2[/tex]

- So this is False.

Combine like terms and add -5 and 3 to get -2:

[tex]=-2x^2+9x-2[/tex]

- So this is False.

Combine like terms and add -5 and 6 to get 1:

[tex]=2x^3-3x+1[/tex]

- So this is True.

Answer:

The square root of 81 is 9, the square root of 9 is 3, your answer is 3

Step-by-step explanation:

3x3=9, 9x9=81

The required squared number that Bradley should give is 9.

Given that,
In a math game, Bradley was supposed to find the square root of a number. Instead, they squared the number and said "81."

To determine the number that should Bradley have given.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the number be x,
Bradley said it is 81
Now accoding to the question,
x = √81
x = √9*9
x = 9

Thus, the required squared number that Bradley should give is 9.

In fact, I can find a formula for them.

The two numbers will always be of the form:

[tex]x_1 =a+b\sqrt c \\x_2 =a-b\sqrt c \\[/tex]

A and B are rational

C is rational and not a perfect square of a rational number

These are irrational because the square root will not resolve to a rational number.

12=(+√)(−√)=2−(√)2=2−2 . Looks rational to me.

1+2=+√+−√=2 , which also is rational.

Answer:

13.7

Step-by-step explanation:

Let us imagine that 0 on the numberline. -9.2 is to the left, and 4.5 is to the right of zero.

Since distance as positive, we can simply add the absolute values of -9.2 and 4.5 to obtain the distance:

|-9.2|+|4.5|=

Answer:

a) The equation of the Parallel line to the given straight line is

       6 x + y + 13 =0

b) Slope - intercept form

        y = - 6 x - 13

c) The intercept - form

            [tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]

x - intercept  =  [tex]\frac{-13}{6}[/tex]

y - intercept = - 13

Step-by-step explanation:

Step(i):-

Given the equation of the straight line

                             y = -6x +1

                  6 x + y - 1 = 0

The equation of the Parallel line to the given straight line is

                6x + y + k=0 and it passes through the point (-3, 5 )

           ⇒ 6 (-3 ) + 5 + k =0

          ⇒  - 18 + 5 + k=0

         ⇒   -13 + k = 0

        ⇒     k = 13

The equation of the Parallel line to the given straight line is

       6 x + y + 13 =0

Step(ii):-

Slope - intercept form

                y = m x + C

                y = - 6 x - 13

Step(iii):-

Intercept - form

              6 x + y + 13 =0

              6 x + y = - 13

              [tex]\frac{6x + y}{-13} = \frac{-13}{-13}[/tex]

             [tex]\frac{6x}{-13} + \frac{y}{-13} = 1[/tex]

             [tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]

The intercept - form

            [tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]

x - intercept  =  [tex]\frac{-13}{6}[/tex]

y - intercept = - 13
