Answer:

B: cos e = 12/17

Step-by-step explanation:

<em>When </em><em>using </em><em>the </em><em>SOHCAHTOA </em><em>method </em><em>you </em><em>can </em><em>see </em><em>that </em><em>Cos </em><em>is </em><em>adjacent</em><em> </em><em>over </em><em>hypotenuse</em><em> </em><em>and </em><em>in </em><em>the </em><em>triangle </em><em>diagram </em><em>they </em><em>give </em><em>you </em><em>the </em><em>measurements </em><em>of </em><em>the </em><em>hypotenuse</em><em> </em><em>and </em><em>the </em><em>adjacent </em><em>only,</em><em> </em><em>so </em><em>you </em><em>know </em><em>that </em><em>they </em><em>would </em><em>be </em><em>using </em><em>the </em><em>cos </em><em>equation</em><em>.</em>

The circumference of a circular field is 279.46 yards. What is the radius of the field? Use 3.14 for π and do not round your ans
wel

Answer:

44.5 yards

Step-by-step explanation:

Start with the formula of the circumference of a circle.

C = πd

Now all you have to do is plug in the numbers.

279.46 = (3.14)d

Divide both sides by 3.14

d = 89

But since you're finding the radius, you have to divide the diameter by 2.

89/2 = 44.5

6v+12b=504<br> 2v+5b=204
ss7ja [257]

Answer:

Step-by-step explanation:

6v + 12b = 504       eq1

2v +  5b = 204        eq2

6v +  15b = 612       eq2  times 3    

0     -3b   = 504 - 612        subtraction of the two bolded eqs

         -3b  =  -108                solve for b

            b  =    36

    Another way to solve the problem

6v + 12b = 504        I would eliminate the v term by multiplying the bottom

2v +  5b = 204        equation by -3 on BOTH sides and then add the two eqs

   2v +  5b  = 204

-3(2v +  5b) = -3(204)

 -6v  -  15b  =  -612

   

6v  + 12b  =   504

-6v  -  15b  =  -612            add the like terms

(6v + (-6v)) + (12b + (-15b)  =  504 + (-612)

(6v -6v)) + (12b - 15b)  =  504 - 612)

    0       +         -3b     =    - 108            solve for b   divide both sides by -3

                           b   =  -108/-3

                             b =  36                  

use eq   2v +  5b = 204       to solve for v       and knowing b = 36

        2v +  5b = 204      b=36

        2v +  5(36)  = 204                 substract 5 times 36 from both sides

                 2v   =   204 - 180

                    v  =    24 / 2

                    v  =  12

NOW CHECK the values for b and v using the OTHER eq

       6v      +     12b      =    504

       6(12)   +   12(36)    =    504

         72    +     432      =    504

                        504      =    504           IT CHECKS
