If the ratio of the surface areas of two similar geometrical solids is given by 121:36, what is the

BigorU [14]

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.

19 3/4−4/9 no example

Jet001 [13]

Answer:

19 11/36

Step-by-step explanation:

19 3/4−4/9

Get a common denominator of 36

19 3/4 *9/9 = 19 27/36

4/9*4/4 = 16/36

19 27/36 - 16/36 = 19 11/36

A plane is approaching an aircraft carrier at 25° angle of elevation from 3.2 miles away how far above sea level is the plane

s2008m [1.1K]

Answer:

$Height\approx 1.35\ miles$

Step-by-step explanation:

The angle of elevation $=25\textdegree$

It is $3.2\ miles$ away from the point.

If we imagine a right triangle having an angle $25\textdegree$ .

Hypotenuse $=3.2$ , Opposite=Height from sea level $(h)$

$\sin 25=\frac{opposite}{hypotenuse}\\\\\sin 25=\frac{h}{3.2}\\\\h=3.2\times \sin 25\\\\h=3.2\times 0.4226\\\\h=1.3524\approx 1.35\ miles$
