Answer:

The height of the smaller cone is 19.52 cm

Step-by-step explanation:

Given that,

The volume of cone 1, V₁ = 3970 cm³

The volume of cone 2, V₂ = 3100 cm³

The height of the larger cone, h₁ = 25 cm

We need to find the height of the smaller cone. Let it is h₂. For similar cones,

$\dfrac{V_1}{V_2}=\dfrac{h_1}{h_2}$

Put values,

$h_2=\dfrac{h_1V_2}{V_1}\\\\h_2=\dfrac{25\times 3100}{3970}\\h_2=19.52\ cm$

So, the height of the smaller cone is 19.52 cm.

Paha777 [63]

Answer:

$y\le\dfrac{1}{2}x+2$

Step-by-step explanation:

On a coordinate plane, a solid straight line has a positive slope and goes through (negative 4, 0) and (0, 2). This line has the equation

$y-0=\dfrac{2-0}{0-(-4)}(x-(-4))\\ \\y=\dfrac{1}{2}(x+4)\\ \\y=\dfrac{1}{2}x+2$

The origin belongs to the shaded region, so its coordinates must satisfy the inequality. Since

$\dfrac{1}{2}\cdot 0+2=2\ge 0,$

then the correct inequality is

$y\le\dfrac{1}{2}x+2$

What is 922/21 as a mixed number?

Fed [463]

Answer:

The answer is 43 and 19 over 21

Step-by-step explanation:

21 goes into 922 43 times. This giving you 903. 43 Will then be your Whole number. You the subtract 922 by 903, this giving you 19. 19 is going to be your numerator. Then you always keep the denomonator which is 21. This giving you 43 and 19 over 21
