Put them in order:

4.7

5.6

7.4

7.9

8.4

10.2

10.6

11.2

13.1

15.4

15.5

Find the middle number:

Since there are 12 numbers, you will have 2 middle numbers which will be the 6th and 7th number: 8.4 and 10.2

Add them together:

8.4 + 10.2 = 18.6

18.6/2 = 9.3

Answer:

the last one 18,36,54,72

Answer:

x = 3, x = 11

Step-by-step explanation:

Since PR is an angle bisector then it divides the opposite side into segments which are proportional to the other 2 sides, that is

[tex]\frac{PQ}{PS}[/tex] = [tex]\frac{QR}{SR}[/tex] , substitute values

[tex]\frac{x+1}{16}[/tex] = [tex]\frac{x-2}{x+1}[/tex] ( cross- multiply )

(x + 1)(x + 1) = 16(x - 2) ← expand left side using FOIL

x² + 2x + 1 = 16x - 32 ( subtract 16x - 32 from both sides )

x² - 14x + 33 = 0 ← in standard form

(x - 3)(x - 11) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 11 = 0 ⇒ x = 11

Answer:

40

Step-by-step explanation:

so first we need to figure out how many money did she save

so she saved 10 dollars

then 50-10=40

so she paid 40 dollars

Answer:

x _> 9 I dont have the symbol on my phone so I just put the greater than sign there

Step-by-step explanation:

1. Subtract 3 from both sides

5x > 48 - 3

2. simplofy 48 - 3 to 45

5x > 45

3. Divide both sides by 5

x > 45/5

4. Then simplify 45/5 to 9 which gives us the answer

And again I dont have the sign thats why I used the greater than sign

Answer:

27

Step-by-step explanation:

In this case, because we have a polynomial where all x-values exist, we can plug the value (x=2) straight into the function:

[tex]\lim_{x \to \ 2} (2x^3+x^2+7)[/tex]

[tex]= 2(2)^3+(2)^2+7[/tex]

[tex]= 2(8)+4+7[/tex]

[tex]= 27[/tex]

The limit of (2x^3+x^2+7) as x approaches 2 equals 27, which makes sense since the value of (2x^3+x^2+7) at x = 2 is 27.

Answer:

Difference = 36

Step-by-step explanation:

Given that,

The boiling point of Oxygen = -183

The melting point of Oxygen = -219

We need to find the temperature difference of the melting point and the boiling point.

Difference = boiling point - melting point

= -183-(-219)

= -183+219

= 36

Hence, the required temperature difference is 36.

Answer:

25 in

Step-by-step explanation:

Hypotenuse is the longest side in the right angle triangle. It is proven by the fact that the square of hypotenus is the sum of the squares of the two other sides.    

The hypotenuse of the Pythagorean triple 25 in, 15 in, 20 in is 25 in

The Pythagoras theorem is used to find the sides of a right angle triangle. The formula below is used to find the sides of a right angle triangle(Pythagoras's theorem) is represented below

where

c = hypotenuse

a and b are either opposite or adjacent sides

A right angle triangle is a triangle that has one of its angles as 90°.

A right angle triangle has the following sides :

The longest side of a right angle triangle is the hypotenuse. Base on the Pythagorean triple, the hypotenuse is 25 inches because its the longest side.
