\dfrac{19}{840}

Step-by-step explanation:

The given fraction is:

\dfrac{1}{168}+\dfrac{3}{180}

We need to solve it.

The LCM of 168 and 180 is 2520.

So,

\dfrac{1}{168}+\dfrac{3}{180}=\dfrac{15+3\cdot14}{2520}\\\\=\dfrac{19}{840}

So, the required answer is equal to \dfrac{19}{840}.

What is the value of y? ​
alexira [117]

9514 1404 393

Answer:

  y = 8√3

Step-by-step explanation:

In the 30°-60°-90° "special" triangle, the ratio of sides lengths is ...

  1 : √3 : 2 = 8 : y : hypotenuse

In order for these ratios to be equal, we must have ...

  y = 8√3

__

If you want to solve this using your trig skills, you recognize that ...

  Tan = Opposite/Adjacent

  tan(30°) = 8/y

  y = 8/tan(30°) . . . . where tan(30°) = 1/√3

  y = 8√3

Drey makes $10 an hour plus $15 an hour for every hour of overtime. Overtime hours are any hours more than 40 hours for the week
gregori [183]
Part A:  W = 10x

Part B:  S = 400 + 15y

Part C:  490 = 400 +15y
              -400  -400
              90 = 15y
              6 = y,  so he worked a total of 46 hours.

PLZZZ HELP ASAP!!!!!!!
patriot [66]

Answer:

2. y = x + 16; 0.21y = 0.27x + 2.88

Step-by-step explanation:

You have two conditions:

  • Volume of 18 % + volume of 27 % = volume of 21 %
  • Mass of acid in 18 % + mass of acid in 27% = mass of acid in 21 %

For the first condition,

16 + x = y     Transpose

(1)    y = x + 16

=====

For the second condition

  V₁c₁    +  V₂c₂  =  V₃c₃

16×0.18 + 0.27x = 0.21y

   2.88 + 0.27x = 0.21y               Transpose

(2)           0.21y = 0.27x + 2.88

The system of equations is y = x + 16; 0.21y = 0.27x + 2.88
