In the isosceles trapezoid ABCD, find the value of x.



10



15



35



5

Answer:

Step-by-step explanation:

Parts + 3($40 labor)=183.30

parts + 120=183.30

parts=63.30 but it includes tax. To find costs of parts before tax you

63.30/1.055=60 so parts are $60

or to solve with one equation:

parts(1.055) + 3($40 labor) = 183.30

parts(1.055) + 120=183.30

parts(1.055)=63.30

Parts = 63.30/1.055

parts = 60

Answer:

u = v - at

Step-by-step explanation:

v = u + at

v - at = u + at - at

v - at = u

u = v - at

Answer:

Which function is represented by this graph?

9

The last option is not even a function, because it ambiguously defines the endpoints.

The first option doesn't define the endpoint, because they are always excluded.

So, the correct option is the second one, because it includes the left endpoint and excludes the right one

the answer is

[tex]32 \sqrt{7} - 24 \sqrt{2} [/tex]

Answer:

[tex]A=75.37\ m^2[/tex]

Step-by-step explanation:

Given that,

The base of a trapezoid, b = 21.6 m

Height of the trapezoid, h = 4.5 m

The tope of the trapezoid, a = 11.9 m

We need to find the area of a trapezoid. The formula for the area of a trapezoid can be given by :

[tex]A=\dfrac{1}{2}\times (sum\ of\ parallel\ sides)\times height[/tex]

Put all the values,

[tex]A=\dfrac{1}{2}\times (21.6+11.9)\times 4.5\\\\=75.37\ m^2[/tex]

Hence, the area of a trapezoid is equal to [tex]75.37\ m^2[/tex].

Answer:

Answer:

Step-by-step explanation:

CI ( 95 % )   means   α = 5 %    α  = 0,05   α /2 = 0,025

If we have a normal distribution and build a CI by symmetry such CI has as a middle point the mean in this case

CI 95 %  =  ( 520 ;  560 )

the mean is (520 + 560 ) / 2  

mean  = 540

Step-by-step explanation:

Answer:

x = 35

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2/7*x-(10)=0

                 2

Simplify   —

                  7

  2        

 (— • x) -  10  = 0

  7        

Subtracting a whole from a fraction

Rewrite the whole as a fraction using  7  as the denominator :

             10             10 • 7

   10 =  ——  =  ——————

               1                 7  

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

           2x - (10 • 7)                       2x - 70

—————————————  =  ———————

                     7                                   7  

Pull out like factors :

  2x - 70  =   2 • (x - 35)

         2 • (x - 35)

 ————————————  = 0

                 7      

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

      2•(x-35)

 ———————— • 7 = 0 • 7

          7    

Now, on the left hand side, the  7  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  2  •  (x-35)  = 0

Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solve  :    x-35 = 0

Add  35  to both sides of the equation :

                     x = 35

Answer:

²¹⁄ₛ which is 21/s

Step-by-step explanation:

Answer:

Slope intercept form:

y = 2x + 8

Step-by-step explanation:

Parallel lines have same slope. SO find the slope of 2x - y = 2

2x - y = 2

    -y = -2x + 2

Multiply both sides by (-1)

-y*(-1) = -2x*(-1) + 2 *(-1)

y = 2x  - 2

Slope = 2

m =2 and point (1 , 10)

Slope point form: y - y1 = m(x -x1)

y - 10 = 2(x - 1)

y - 10 =2x - 2

    y = 2x - 2 + 10

   y = 2x + 8

The expanded form is y=716x7

Step-by-step explanation:

Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression. 5,325 in expanded notation form is 5,000 + 300 + 20 + 5 = 5,325.

Answer:

[tex]Mother = 30\ years[/tex]

[tex]Son = 10\ years[/tex]

Step-by-step explanation:

Given

[tex]M = Mother[/tex]

[tex]S = Son[/tex]

From the first statement:

[tex]M = 3S[/tex]

From the second:

[tex]M - S = 20[/tex]

Required

Find M and S

We have:

[tex]M = 3S[/tex] and

[tex]M - S = 20[/tex]

Substitute [tex]M = 3S[/tex] in [tex]M - S = 20[/tex]

[tex]3S -S =20[/tex]

[tex]2S = 20[/tex]

Divide both sides by 2

[tex]S = 10[/tex]

Substitute [tex]S = 10[/tex] in [tex]M = 3S[/tex]

[tex]M = 3 * 10[/tex]

[tex]M = 3 0[/tex]

Hence;

[tex]Mother = 30\ years[/tex]

[tex]Son = 10\ years[/tex]
