Answer:
174 people preferred drinking water.
Step-by-step explanation:
Given that:
A total of 450 males and females were surveyed.
203 were males.
Number of females = 450 - 203 = 247 females
247 females were surveyed.
Now, we will find the number of females who prefer water.
Let,
x be that number.
Total number of females = Soda + Iced tea + Lemonade + Water
247 = 28 + 44 + 67 + x
247 = 139 + x
247-139 = x
x = 108
Number of people who prefer water = 108 + 66 = 174
Hence,
174 people preferred drinking water.
Answer:
22 sides
Step-by-step explanation:
The expression to find an interior angle of a polygon is:

The expression to find an exterior angle of a polygon is:

Please note that "n" represents the number of sides the polygon has.
We can use these two expressions to set up an equation.

Multiply both sides by "n":

Now, distribute:

Divide both sides by 10:


Add 36 to both sides:

Divide both sides by 18:

The polygon has 22 sides
The value of the 5 in 756 is 50
Rewrite 3 3/4 as an improper fraction
3 3/4 = 15/4
Now you have
15/5 / 5/7
When you divide fractions, change the division to multiplication and flip the second fraction over:
15/4 x 7/5
Now multiply the top numbers together and the bottom numbers together:
( 15 x 7) / (4 x 5) = 105/20
Write as a proper fraction:
105/20 = 5 1/4
