Inverse variation:  y = k/x.  Here x=7 and y=8.  Thus,

y = k/x becomes 8 = k/7, or k=56.  The const. of var. is 56.

uranmaximum [27]

Answer:

It'd be 4/15

Step-by-step explanation:

The total marbles is 6, so for black it's 4/6, but it's not being put back in so for the next one, the denominator would be 5. For green it's 2/5

4/6 times 2/5 equal 4/15

Hope this helps!

What is the inverse function of f(x)= 4- x/6
Westkost [7]

Answer:

f^{-1}(x) = 6(4-x) = 24-6x

Step-by-step explanation:

Let y=f(x) and swap x and y:

x = 4 - \frac{y}{6}

Then, rearranging for y:

x+\frac{y}{6} = 4

\frac{y}{6}= 4-x

y= 6(4-x) = 24-6x

What is the lateral area of a right cylinder if the radius of the base is 12 mm and the altitude of the cylinder is 5 times the
lakkis [162]
The lateral area of a cylinder is given by:
Area=πrl+2πr^2
radius,r=12 mm
length,l=5*12=60mm
therefore the lateral area will be:
Area=π*12*60
Area=2,261.95 mm^2
The area of the bases will be:
A=2*π*12^2=904.78 mm^s
The lateral area will be:
2,261.95+904.78
=3,166.73
=3167 mm^2
