1 second = 2 megabytes

1\frac{1}{2}\ seconds=3\ megabytes

2 seconds = 4 megabytes

Step-by-step explanation:

Given,

Time taken to download 5 megabytes = 2\frac{1}{2}=\frac{5}{2} seconds

\frac{5}{2}\ seconds = 5\ megabytes

Multiplying both sides by \frac{2}{5} to find unit rate

\frac{2}{5}*\frac{5}{2}\ second = \frac{2}{5}*5\\1\ second = 2\ megabytes

1 second = 2 megabytes

1\frac{1}{2}\seconds = \frac{3}{2}\ seconds

\frac{3}{2}\ seconds = \frac{3}{2}*2

\frac{3}{2}\ seconds = 3\ megabytes

1\frac{1}{2}\ seconds=3\ megabytes

2 seconds = 2*2 megabytes

2 seconds = 4 megabytes

Find the measure of one interior angle for the following regular polygon ​
kipiarov [429]

Answer:

144 degrees

Step-by-step explanation:

We can use the formula (n-2)(180), where n = number of sides, to find the sum of all the interior angles in the decagon. Since a decagon has 10 sides:

(n-2)(180) = ?

(10-2)(180) = ?

(8)(180) = 1440.

Now, to find one interior angle in the decagon, divide 1440 by the number sides in our polygon (10).

1,440/10 = 144

               = <u>144 degrees</u>
