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.

Find the measure of one interior angle for the following regular polygon

garik1379 [7]

To find the sum of the interior angles you use the formula (n-2)(180), where n is the number of sides. In this case, the number of sides is 12, so you get 1800 degrees. Then you divide by number of angles which is 12. So your answer is 150 degrees.

Show your work AND the answer a research showed that 45% of sixth graders have dogs for pets 35% have cats 10% have fish and 5%

Arturiano [62]

Answer: 600 students

Step-by-step explanation:

Of the total number of sixth graders who were surveyed, 5% owned birds.

This 5% translated to 30 students.

30 students is therefore 5% of the total number of sixth graders surveyed.

Assume that number to be x:

x * 5% = 30

x = 30 / 5%

= 600 students
