Answer:

109

Step-by-step explanation:

Formula

<ZHG + <IHZ = <IHG

Givens

<ZHF = 11x - 1

<IHZ = 24

<IHG = 12x + 13

Solution

11x - 1 + 24 = 12x + 13             Combine terms on the left

11x + 23 = 12x + 13                  Subtract 13 from both sides

     - 13             - 13  

11x + 10 = 12x                           Subtract 11x from both sides

-11x           -11x

        10 =   x

Answer

11x - 1 = 11*10 - 1 = 110 - 1 = 109

Answer:

It would be A

Step-by-step explanation:

difference means subtraction, in in order to avoind PEMDAS making it the difference of 3 times 8 and x, you need to add parentheses.

sorry if that made no sense lol

Answer:

A. 3(8-x)

Step-by-step explanation:

the difference means subtracting and the times means multiple

to multiple the difference of 8 and x, you must find a way to changed the order in a way that one portion is solved before the other. you must add parenthesis to force 8 to subtract from x before 8 can be multiplied by 3.

therefore 3(8-x)

Answer:

13.7

Step-by-step explanation:

c^2 - b^2 = a^2

16.5^2 - 9.2^2 = a^2

272.25 - 84.64 = square root of a

square root of 187.61

= about 13.66 or 13.7

Answer:

X=80

Step-by-step explanation:

I suppose the graph will be like this:

Since isosceles trapezoid, red lines are parallel.

X+x+20= 180

Answer:

Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.

Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m.

There are two ways to write 32 as the sum of two prime numbers: i) 13 + 19 = 32 ii) 3 + 29 = 32

Answer:

[tex]a_{n}[/tex] = 1.3n - 4.7

Step-by-step explanation:

There is a common difference d between consecutive terms

d = - 2.1 - (- 3.4) = - 0.8 - (- 2.1) = 0.5 - (- 0.8) = 1.8 - 0.5 = 1.3

This indicates the sequence is arithmetic with nth term ( explicit rule )

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 3.4 and d = 1.3 , then

[tex]a_{n}[/tex] = - 3.4 + 1.3(n - 1) = - 3.4 + 1.3n - 1.3 = 1.3n - 4.7

A recursive rule allows a term in the sequence to be found by adding d to the previous term, that is

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 1.3 : a₁ = - 3.4

Answer:

My theory is that it is a pyramid and that you have to find the volume of it??

6*7=42

42*3=126??????

????

i dont know sorry if wrong

As we know that,

[tex]\bigstar \: \boxed{\sf {Area_{(Trapezium)} = \dfrac{1}{2} \times ( a + b) \times h}} \\ [/tex]

Substituting values, we get :

[tex] \longmapsto [/tex] Area = [tex]\sf \dfrac{1}{2} [/tex] × ( 60 + 40 ) × 30 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = [tex]\sf \dfrac{1}{2} [/tex] × 100 × 30 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = 1 × 100 × 15 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = 100 × 15 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = 1500 ft[tex] \sf ^2 [/tex]

Therefore,

C:section c

Given:

The table of values of a linear function.

To find:

The equation of linear function in slope intercept form.

Solution:

The slope intercept form of a linear function is:

[tex]y=mx+b[/tex]

Where, m is the slope and b is the y-intercept.

If a linear function passes through two point, then the equation of the linear function is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Consider any two points from the given table. Let the two points are (-6,12) and (-5,14). So, the equation of the linear function is:

[tex]y-12=\dfrac{14-12}{-5-(-6)}(x-(-6))[/tex]

[tex]y-12=\dfrac{2}{-5+6}(x+6)[/tex]

[tex]y-12=\dfrac{2}{1}(x+6)[/tex]

[tex]y-12=2x+12[/tex]

Adding 12 on both sides, we get

[tex]y-12+12=2x+12+12[/tex]

[tex]y=2x+24[/tex]

Therefore, the slope intercept form for the given linear function is [tex]y=2x+24[/tex].

Answer: 117

Step-by-step explanation:

Formula for arithmetic sequence is:

= a + (n - 1)d

22nd term = a + (n - 1)d

= a + (22 - 1)d = a + 21d

where, a = 12

d = 17 - 12 = 5.

Therefore, 22nd term will be:

= a + 21d

= 12 + 21(5)

= 12 + 105

= 117

The 22nd term is 117
