y varies jointly as x and z. y equals 80y=80 when x equals 5x=5 and z equals 4z=4. Find y when x equals 4x=4 and z equals 6z=6.
Lubov Fominskaja [6]
\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad  y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad  variation
\end{array}\\\\
-------------------------------\\\\

\bf \textit{\underline{y} varies jointly as \underline{x} and \underline{z}}\implies y=kxz
\\\\\\
\textit{we also know that }
\begin{cases}
y=80\\
x=5\\
z=4
\end{cases}\implies 80=k(5)(4)\implies 80=20k
\\\\\\
\cfrac{80}{20}=k\implies 4=k\qquad thus\qquad \boxed{y=4xz}\\\\
-------------------------------\\\\ if~\begin{cases}
x=4\\
z=6
\end{cases}~\textit{what is \underline{y}?}\qquad y=4(4)(6)

What is the measure of xyz
kakasveta [241]

Answer:

The correct answer is option B.  65

Step-by-step explanation:

<u>To find the measure of <VYX</u>

Central angle of arc VW = 44°

Therefore m<VXY = 44/2 = 22°

And central angle of arc XZ = 86° therefore <XVY = 86/2 = 43

<u>To find the mesure of <XYZ</u>

m<XYZ = m<VXY + m<XVY

  = 22 + 43

 = 65°

Therefore the correct answer is option B. 65°

A large tire company has 230 employees. There are 4 times as many mechanics as supervisors, and 10 more supervisors than account
Alex787 [66]
So your variable are these
x= # of accountants
x+10= # of supervisors
4(x+10)= # of mechanics
So you get the equation x+ (x+10) + (4x+40) = 230
and you solve for x
6x + 50 = 230
6x = 180
x=30
so accountants = 30
supervisors = 40
Mecahnics = 160
