If you are looking for the answer of z when x=7 and y=6, you’ve got the right page. We have approximately 10 FAQ regarding z when x=7 and y=6. Read it below.
z varies jointly as x and y and z=60 when
Ask: z varies jointly as x and y and z=60 when x=5 and y=6 Find z when x=7 and y=6
z=kxy
60=k(5)(6)
k=60/30
k=2 Therefore the equation is z=2xy
z=kxy
z=(2)(7)(6)
z=(14)(6)
z=84 Therefore the equation is 84=kxy
Z varies jointly as X and y and Z=60 when
Ask: Z varies jointly as X and y and Z=60 when X=5 and y=6
A.find Z when X=7 and Y=6
B.find X when Z=72 and Y=4
C.find Y when Z=80 and X=4
Pleaseeeeeeee Answeeeer
Step-by-step explanation:
a.Z=7
sorry yan lang ang kaya koh
Answer:
B. find X when Z=72 and Y=4
z varies jointly as x and y and z=60 when
Ask: z varies jointly as x and y and z=60 when x=5 and y =6.
a.Find z when x=7 and y=6
b.Find x when z=72 and y=4
c.Find y when z =80 and x=4
Step-by-step explanation:
z varies jointly as x and y and z=60 when x=5 and y =6.
z = kxy
60 = k(5)(6)
60 = k30
k=60/30
k = 2
a.Find z when x=7 and y=6
z = 2(7)(6)
z = 84
b.Find x when z=72 and y=4
72 = 2(4)x
72 = 8x
x = 72 /8
x = 9
c.Find y when z =80 and x=4
80 = 2(4)y
80 = 2(4)y 80 = 8y
80 = 2(4)y 80 = 8y y = 80/8
80 = 2(4)y 80 = 8y y = 80/8 y = 10
1. z varies jointly as x and y and z
Ask: 1. z varies jointly as x and y and z = 60 when x = 5 and y = 6.
a. Find z when x = 7 and y = 6.
b.Find x when z = 72 and y = 4.
c. Find y when z = 80 and x = 4.
Answer:
a. Z = 84
b. X = 9
c. Y = 10

JOINT VARIATION
==============================
Solve:
[tex] implies sf large z = kxy[/tex]
[tex] large tt red{given} begin{cases} sf : z = 60 \ sf : x = 5 \ sf : y = 6 end{cases}[/tex]
[tex] : [/tex]
Find the constant of the variation (k), use the given to substitute.
[tex] implies sf large 60 = k(5)(6)[/tex]
[tex] implies sf large 60 = k(30)[/tex]
[tex] implies sf large frac{60}{30} = frac{k( cancel{30})}{ cancel{30}} \ [/tex]
[tex] implies sf large therefore : k =2[/tex]
==============================
A. Find z when x = 7 and y = 6.
[tex]large tt red{given(A)} begin{cases} sf : k = 2 \ sf : x = 7 \ sf : y = 6 end{cases}[/tex]
[tex]implies sf large z = 2(7)(6)[/tex]
[tex] sf large implies huge orange{z = 84}[/tex]
==============================
B. Find x when z = 72 and y = 4.
[tex]large tt red{given(B)} begin{cases} sf : k = 2 \ sf : z = 72 \ sf : y = 4 end{cases}[/tex]
[tex]implies sf large 72 =2x(4)[/tex]
[tex]implies sf large 72 =8x[/tex]
[tex]implies sf large frac{72}{8} = frac{ cancel8x}{ cancel8} \ [/tex]
[tex]sf large implies huge orange{x = 9}[/tex]
==============================
C. Find y when z = 80 and x = 4.
[tex]large tt red{given (C)} begin{cases} sf : k = 2 \ sf : x = 4 \ sf : z = 80 end{cases}
[/tex]
[tex]implies sf large 80 =2(4)y[/tex]
[tex]implies sf large 80 =8y[/tex]
[tex]implies sf large frac{80}{8} = frac{ cancel8y}{ cancel8} \[/tex]
[tex]sf large implies huge orange{y = 10}[/tex]

Z varies jointly as x and y and z=60 when
Ask: Z varies jointly as x and y and z=60 when x=5 and y=6.
a.Find z when x=7 and y=6.
b.Find x when z=72 and y=4.
c.Find y when z=80 and x=4.
EQUATION: Z = kxy
60 = k (5)(6)
60 = k (30)
60 / 30 = k 30 / 30
2 = k
a. z = (2)(7)(6)
z = 84
ANSWER: z = 84
b. 72 = (2) x (4)
72 = 8x
72 / 8 = 8x / 8
9 = x
ANSWER: 9 = x
c.80 = (2)(4) y
80 = 8y
80 / 8 = 8y / 8
10 = y
ANSWER: 10 = y

[tex]cary : on : learning : \ \ brainlest : bunch \ \ \ stay : safe [/tex]
Answer:
84
Step-by-step explanation:
z = k xy
60 = k 5*6
k = 60 / 30
k = 2
z = (2) * 7 * 6
z = 84
Z varies jointly as x and y and z=60 when
Ask: Z varies jointly as x and y and z=60 when x=5 and y=6
Find z when x=7 and y=6.
Answer
Um Z varies jointly as x and y and z=60 when x=5 and y=6
Find z when x=7 and y=6. aswer iiiissss 7? iguess
Step-by-step explanation:
ok
Z varie jointly a x and y and z=60 when
Ask: Z varie jointly a x and y and z=60 when x=5 and y=6. Find z when x=7 and y=6.
z = kxy
60 = k(5)(6)
60 = 30k
60/30 = k
k = 2
z = 2xy
z = 2(7)(6)
z = 84
