Answer:

1331:216

Step-by-step explanation:

Given the ratio of the lengths of two similar solids as a:b

The ratio of the surface areas = $a^2:b^2$

The ratio of the volume = $a^3:b^3$

We are given that the ratio of the surface areas of two similar geometrical solids is given by 121:36

Therefore:

$a^2:b^2=121:36\\\implies a^2:b^2=11^2:6^2\\\implies a:b=11:6$

Since the ratio of the lengths is 11:6

The ratio of their volumes = $11^3:6^3$

=1331:216

The ratio of the volume of the two similar geometrical solids is 1331:126.

Which number line represents the solution set for the inequality-1/2x>_4

Vesna [10]

Answer:

Step-by-step explanation:

Firstly, we solve for x

-x ≥ 2 * 4

-x ≥ 8

Multiply both sides by -1

x ≤ -8

So we look at the inequality represented by this;

We can see that the correct inequality is option B;

What does it mean for a differential equation to be autonomous?

andrew11 [14]

The term "autonomous" refers to an ordinary differential equation that relates the derivatives of the dependent variable as a function *only* of the dependent variable. In other words, the ODE doesn't explicitly depend on the independent variable.

Examples:

$y'=y^2-1$ is autonomous

$y'=y^2-1+x$ is *not* autonomous

What does x=?........................

Bas_tet [7]

Answer:

x = -25 / 3

Step-by-step explanation:

10 / 3 = x / (-5/2)

10 / 3 * (-5 / 2) = x

x = -50 / 6

x = -25 / 3

Convert the cartesian equation x2 +y2=16 to a polar equation

VARVARA [1.3K]

X^2+y^2 = 16
can be written as
(x-0)^2+(y-0)^2 = 4^2

We see that the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2

where
(h,k) = (0,0) is the center
r = 4 is the radius

The polar form of the equation is simply r = 4. Why is this? Because the radius is fixed to be 4 no matter what happens with theta. As theta goes from 0 to 360, the points generated all form a circle centered at (0,0) with radius 4.

Answer: r = 4

Help plzzz!!! Find a a= 12 a= 10 a= 1 a= 29

RideAnS [48]

Answer:

a=22.6549

Step-by-step explanation:

Calculated based on 2 given angles and 1 given side.

∠C = 180° - A - B = 0.99484 rad = 57°

a = c·sin(A)/sin(C) = 22.6549

b = c·sin(B)/sin(C) = 12.33874
