Which two numbers add up to ___ and multiply to ___?can you help me with this? Multiplied 1 adds to 10

irina [24]

Begin by following the herd . . . call the two numbers 'x' and 'y' .

You said that xy=1 , so y = 1/x

You said that x + y = 10, so x + 1/x = 10

Multiply each side by 'x': x² + 1 = 10x

Subtract 10x from each side: x² - 10x + 1 = 0

Use the quadratic formula to solve this, and the two solutions
that you get for 'x' are also the two numbers 'x' and 'y' .
They are

 9.89898
and

Answer:

The ratio of their volumes is: $\frac{729}{64}$

Step-by-step explanation:

If the cones are similar, then the ratio of their heights should equal the ratio of their radiuses. If we call R the radius of the larger cone (the one of height 9 cm) and r the radius of the smaller cone (the one of height 4 cm), then the following proportion should be verified:

$\frac{R}{r} =\frac{9}{4} \\R=\frac{9\,r}{4}$

where we have solved for "R" in terms of "r".

Now we input this information in the formula for the volume (V) of the largest cone, and for the volume (v) of the smaller cone, recalling that the volume of a cone is the product of the area of the cone's circular base ( $\pi *\,radius^2$ ).

$v=\frac{\pi\,r^2\,4\,}{3} =\pi r^2\,\frac{4}{3} \\V=\frac{\pi\,R^2\,9}{3}=\frac{\pi\,(\frac{9\,r}{4} )^2\,9}{3}=\frac{\pi\,r^2\,729}{16*3}=\pi r^2\,\frac{243}{16}$

So now the ratio of their volumes (V/v) can be obtained:

$\frac{V}{v} =\frac{\frac{243}{16}}{\frac{4}{3}} =\frac{729}{64}$
