Answer:

40⁰

Step-by-step explanation:

Main principles:

1.Alternate angles equal

2.Vertically opposite angles are equal

If angle 2 is 40⁰, then using the second principle,angle 3 is also 40⁰

Then, using the first principle,(alternate angles/angles that form any variation of "z"), angle 6 is also 40⁰.

There are other ways to do this like using co-interior angles, straight angles and other methods, these are the easiest to understand

Answer:

[tex]4x + 8[/tex]

Step-by-step explanation:

Hi!

So we have to use the distributive property here and distribute 4 to both the x and the 2.

So we do

[tex](4*x)+(4*2)[/tex]

Simplify further:

[tex]4x + 8[/tex]

That's your answer

Answer:

$1.40

Step-by-step explanation:

Answer:

The price of the book is $7.75.

Step-by-step explanation:

Let's first establish an equation.

If I buy a book costing [tex]x[/tex] dollars and a bookmark costing 1 dollars, I will have spent [tex]x + 1[/tex] dollars. So a group of 15 people doing the same will have spent [tex]15(x+1) = 15x + 15[/tex] dollars.

Analogously, the group of 3 people has spent [tex]3(x+36) = 3x + 108[/tex] dollars.

Since we know that both groups spent the same amount of money, we can set the two expressions equal to each other:

[tex]15x+15=3x+108\\12x=93\\x=7.75[/tex]

Because [tex]x[/tex] was the price of the book, which was asked for in the question, we conclude that the answer is $7.75.

Answer:

Mean = average or the sum of all numbers divided by how many numbers there are.

2 + 2 + 8 + 10 + 15 + 30 + 36 + 40 + 50 + 51 = 244

244/10 = 24.4

Answer:

24.4

Step-by-step explanation:

Add all numbers together To get 244

Then divide by the number of numbers given (10)

244÷10 = 24.4

Answer:

2

Step-by-step explanation:

Simplify the following:

(-6 - 4)/(-5)

Hint: | Group the negative terms in -6 - 4 together and factor out the minus sign.

-6 - 4 = -(6 + 4):

(-(6 + 4))/(-5)

Hint: | Evaluate 6 + 4.

6 + 4 = 10:

(-10)/(-5)

Hint: | In (-10)/(-5), the numbers 10 in the numerator and -5 in the denominator have gcd greater than one.

The gcd of 10 and -5 is 5, so (-10)/(-5) = (-(5×2))/(5 (-1)) = 5/5×(-2)/(-1) = (-2)/(-1):

(-2)/(-1)

Hint: | Cancel common terms in the numerator and denominator of (-2)/(-1).

(-2)/(-1) = (-1)/(-1)×2 = 2:

Answer: 2

The equivalent value of the fraction is A = 2

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the numerator of the fraction be p

Let the denominator of the fraction be p

Now , A = p/q

when the value of p = ( -6 - 4 )

And , when the value of q = ( -5 )

On simplifying the equation , we get

A = ( -6 - 4 ) / ( -5 )

So , the left hand side of the equation is equated to the right hand side by the value of ( -6 - 4 ) / ( -5 )

A = ( -6 - 4 ) / ( -5 )

A = ( -10 ) / ( -5 )

On simplifying , we get

Divide by -1 on both numerator and the denominator , we get

A = 10/5

A = 2

Therefore , the value of A = 2

Hence , the fraction is A = 2

Step-by-step explanation:

Answer:

11.2 m

Step-by-step explanation:

The distance from the ground to the top of the tree = h

Using Pythagoras rule :

Adjacent² = hypotenus² - opposite²

h² = 15² - 10²

h² = 225 - 100

h² = 125

h = Sqrt(125)

h = 11.18

h = 11.2 m to the nearest tenth
