Which formula can be used to find the sum of the measures of all the interior angles of a regular polygon with n sides?

The expression (2x^2)^3 is equivalent to _____. 6x^2 6x^5 8x^6

4vir4ik [10]

Answer:

$8x^{6}$

Step-by-step explanation:

To solve this problem is multiply 2 by 2 and then 2 which gives you 8.

Then you will add 2+2+2 and get six. For when multiply exponents you are adding.

What is the measure of one interior angle of a polygon that has 50 sides

pashok25 [27]

Answer: 172.8°

Step-by-step explanation:

For a regular polynomial of N sides, the sum of all interior angles must be equal to:

Sum = (N - 2)*180°.

In this case we have N = 50

Then:

Sum = (50 - 2)*180° = 48*180°

Now, if all the 50 interior angles have the same measure, then the measure of each one will be equal to the quotient between the sum and the number of sides, this is:

Sum/50 = (48/50)*180° = 172.8°

Then the interior angles of a regular polygon of 50 sides is 172.8°

A scientist measured the wavelength of an X-ray as 0.0000000065 meters.

ryzh [129]

Answer:

6.5 * 10 ^ -9

Step-by-step explanation:

0.0000000065

Scientific notation means a* 10 ^b

where a is number between 1 and less than 10

Move the decimal 9 places to the right which means the power of 10 is negative since we moved the decimal to the right

6.5

The power of 10 is -9

6.5 * 10 ^ -9

Lillian and Isabella went shopping for school supplies. Lillian found her favorite notebook on sale so she bought three of the e

ASHA 777 [7]

Answer:

Each girl had $7.50 when they arrived.

Step-by-step explanation:

We have to figure out what c (cost of each notebook) is first before we find out how much money each girl had. We also know they have the same money, so both sides are connected. The equation should be: 3x = x + 5.

3x = x + 5

First, subtract x from both sides. This cancels out the addition by x.

3x - x = 5

Now, subtract x from 3x. This equals 2x.

2x = 5

To cancel out the multiplication by 2, divide both sides by 2.

x = 5/2

Lastly, divide 5 by 2 to get 2.5.

x = 2.5

Substitute x for 2.5 in the earlier equation (3x = x + 5)

3(2.5) = 2.5 + 5

First, multiply 3 by 2.5 to get 7.5.

7.5 = 2.5 + 5

Add 2.5 to 5 to get 7.5.

7.5 = 7.5

Both sides are equal so we have our answer. So, both girls had $7.50 when they arrived at the store.
