Answer:

a=c/b-d/b

Step-by-step explanation:

Answer:

a=c-d/b

Step-by-step explanation:

We first need to isolate the variable "a" by doing the opposite operation.

1. subtract "d" on both sides

After step 1-     ab=c-d

2. divide both sides by "b" because that is the only way to isolate a permanently

After step 2-     a=c-d/b

Step-by-step explanation:

QS bisects the ^PQR^ :

So -----¢ PQS = SQR = 45°

_________________________________

PQR = PQS + SQR = 45°+ 45° = 90 °

Q^ = 90° ----¢ So the PQR triangle is a

right triangle.

Complete Question

Engineers must consider the breadths of male heads when designing helmets. The company researchers have determined that the population of potential clientele have head breadths that are normally distributed with a mean of 6.4-in and a standard deviation of 0.9-in.If you were to draw samples of size 47 from this population, in what range would you expect to find the middle 50% of most averages for the breadths of male heads in the sample

Answer:

The range is  from   [tex] \=x_1   = 6.312 [/tex]  to  [tex] \=x_2  = 6.488  [/tex]

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = 6.4 \ in[/tex]

   The standard deviation  [tex]\sigma =  0.9 \  in[/tex]

    The sample  size is  n  =  47  

Generally the standard error is mathematically represented as

               [tex]\sigma_{\= x} =  \frac{0.9}{\sqrt{47} }[/tex]

=>             [tex]\sigma_{\= x} =   0.13128 [/tex]

Generally the proportion where the middle 50% of most average for the breaths of male heads in the sample is mathematically evaluated as

 [tex]P(\= x_1 <  \= X  <  \= x_2 ) =  P(\frac{\=x_1 - \mu }{\sigma_{\= x} } < \frac{\= X - \mu }{\sigma_{\= x} }   <  \frac{\=x_2 - \mu }{\sigma_{\= x} } ) =  0.5[/tex]

Generally  [tex]\frac{\= X - \mu }{\sigma_{\= x} }  =  Z(The \  standardized \  value  \  of  \  \= X )[/tex]

So

 [tex]P(\= x_1 <  \= X  <  \= x_2 ) =  P(\frac{\=x_1 - 6.4}{ 0.13128 } <Z  <  \frac{\=x_2 - 6.4 }{0.13128} ) =  0.5[/tex]  

From the z table  the z-score of  0.5 is

  [tex]z-score =   \pm 0.674[/tex]

So

      [tex]\frac{\=x_1 - 6.4}{ 0.13128 } = -0.674[/tex]

       [tex] \=x_1   = 6.312 [/tex]

and

        [tex]\frac{\=x_2 - 6.4}{ 0.13128 } = 0.674[/tex]

          [tex] \=x_2  = 6.488  [/tex]

Answer:

75feet

Step-by-step explanation:

To measure a stone face carved on the side of a​ mountain, two sightings 700 feet from the base of the mountain are taken. If the angle of elevation to the bottom of the face is 35 and the angle of elevation to the top is 38 ​, what is the height of the stone​ face?

Iet us say we have two right triangles. With a base of 700. The first has angle of 35o and the other has an angle of 38degree

Then we need the Height

From trigonometry

Tan = opposite/adjacent.

In this case the adjacent is 800

Tan 35 = 0.7002

Tan 38 = 0.781

Answer:

the final cost is $31.74

Answer:

If the discriminant is less than 0, the equation has no real solution. Looking at the graph of a quadratic equation, if the parabola does not cross or intersect the x-axis, then the equation has no real solution. And no real solution does not mean that there is no solution, but that the solutions are not real numbers.  The Zero-Product Property states that for all real numbers a and b, if [tex]ab=0[/tex], then a=0 or b=0.

We can The Zero-Product Property to solve a quadratic equation when we can factor the standard form of the equation. Because when we apply The Zero-Product Property to a factored quadratic equation we can find the x-intercepts of the graph of the related functions. Respectively we can find the solutions to the quadratic equation.

Answer:

The function is Speed, f(t) = x/t

Step-by-step explanation:

The given information are;

The distance the man drove = 40 miles

The duration of time the man drove = 2-hours

Given that a function maps each item of the input domain to a single item of the output domain, we can have the following relation for the above parameters;

Speed = (Distance travelled)/(Time taken)

Where, speed f(t), is a function of the time taken, t, to travel a distance x

The function is therefore;

Speed, s = f(t) = x/t

Speed = 40/2 = 20 mile per hour.

Answer:

The function is Speed, f(t) = x/t

Answer:

47°

Step-by-step explanation:

a staight angle equals 180 degrees

180=6x+29+3x+124

x=3

18+29=boc

boc=47

btw, if u know how to do my question could u plz help

thx

Answer:  angle BOC is 47°

Step-by-step explanation:

Supplementary angles add to 180°

6x + 29 + 3x + 124 = 180

6x + 3x + 29 + 124 = 180

9x + 153 = 180

9x = 180 -153

9x = 27

x = 3

Substitute 3 for x in   ∠BOC = 6x +29

6(3) + 29 = ∠BOC

18 + 29

47° =m∠BOC

Answer:

x = -1/2

Step-by-step explanation:

50x + 54 = 34x + 46

Subtract 34x from each side

50x-34x + 54 = 34x-34x + 46

16x +54 = 46

Subtract 54 from each side

16x+54-54 = 46-54

16x = -8

Divide by 16

16x/16 = -8/16

x = -1/2

Answer:

[tex]x=-\frac{1}{2}[/tex]

Step-by-step explanation:

So we are given an equation and we are asked to solve for x.

50x + 54 = 34x + 46

Subtract 54 from both sides.

50x = 34x - 8

Subtract 34x from both sides.

16x = -8

Divide both sides by 16.

[tex]x=-\frac{1}{2}[/tex]

So now we have solved for x. We have found that [tex]x=-\frac{1}{2}[/tex].

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

Step-by-step explanation:

m<1 = 90 -38 = 52

m<3 = 90 - 52 = 38\

m<2 = 180-38-63 = 79

Answer:

Step-by-step explanation:

<1 + <3 = 90                 Parallel lines produce interior angles that add to to 90

<1 + 38 = 90                 Substitution

<1 = 90 - 38                  52

<3 = 90 - 52

<3 = 38

38 + 63 + <2 = 180      Sum of angles in a triangle always = 180

101 + <2 = 180

<2 = 79

Answer:

2(-2)2=0

Step-by-step explanation:

if you meant to put it a different way tell me and i can do the correct one, just because this one seems weird lol

The value of the function when x = -2 then g(-2) = 4.

A function is defined as a relation between the set of inputs having exactly one output each. The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can be represented by mathematical symbol.

WE have been given an function as g(x) = 2x² - 4

Now plug the value x = -2 in the given function;

g(-2) = 2(-2)² - 4

g(-2) = 2 x 4 - 4

g(-2) = 8 - 4

g(-2) = 4

Therefore, the value of the function when x = -2 then g(-2) = 4.
