Answer:
x = 127 degrees
Step-by-step explanation:
The sum of the interior angles is (n-2)180, so in this case it would be
(6-2)180
(4)180
720
Then you can substitute the given angle measurements to get the equation:
112+133+128+100+120+x = 720
593+x = 720
x = 127
Answer:

Step-by-step explanation:
The equation for photon energy is given by:

Where:

This equation telling us that the higher the frequency of the photon, the greater its energy. And the longer the photon wavelength, the lower its energy.
So, replacing the data provided in the previous equation:

Answer:
Simplifying the expression:
we get 
Step-by-step explanation:
We need to simplify the expression: 
First we will solve terms inside the bracket

Converting mixed fraction
into improper fraction, we get: 
Replacing the term:

Now, taking LCM of: 5,3,4,2 we get 60
Now multiply 60 with each term inside the bracket

Now, combine like terms

Now, multiply all terms with 2

So, Simplifying the expression:
we get 
Answer:
-2/-3
Step-by-step explanation:
(75, 60) (45, 40)
75 60 since 75 is larger than 45, we subtract = -30
45 40 since 60 is larger than 40, we subtract = -20
= -20/-30
reduce
= -2/-3
Answer:
18 ounce package for $6.30
Step-by-step explanation:
For each one, you divide the money by the package to see how much it is per ounce.
2.59 / 7 = $0.37 per oz
4.56 / 12 = $0.38 per oz
6.30 / 18 = $0.35 per oz
