Answer: 12

Step-by-step explanation: The mean is basically the average. So, start by lining up the numbers from smallest to largest. 1, 3, 4, 8, 14, 18, 19, 19, 22. Then, add them all together. You get 108. Then, divide 108 by the number or numbers in the data set, which in this case is 9. So 108 divided by 9 = 12. Your answer is A. --> 12

Hope that helped!!

The two solids are similar and the ratio between the lengths of their edges is 2:7 what is the ratio of their surface areas?

vovangra [49]

Answer:

The ratio of their surface areas is $\frac{4}{49}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

In this problem the scale factor is equal to the ratio $\frac{2}{7}$

and

Remember that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

therefore

In this problem the ratio of their surface areas is $(\frac{2}{7})^{2}=\frac{4}{49}$

Geometry math question please help

stiks02 [169]

You need this key result: in any polygon, the sum of the interior angles is

$(n-2)\times 180$

where $n$ is the number of sides of the polygon.

Your polygon has seven sides, and the measures of all angles are given. So, we can write

$2x+4x+4x+4x+4x+2x+10x = (7-2)\times 180$

Again, we've simply written that the sum of all interior angles is the number of sides, minus two, times 180.

We can simplify both sides: we sum like terms on the left hand side, and we easily compute the right hand side:

$30x = 5\times 180 = 900$

and we can solve this equation for $x$ by dividing both sides by 30:

$x = \cfrac{900}{30} = 30$

Finally, the required angles is $2x = 2\times 30 = 60$
