Answer:
2⅝
Step-by-step explanation:
You must convert each fraction to a <em>common denominator</em>.
The <em>least common multiple</em> of 2, 4, and 8 is 8.
   1/4  +3/8  + 1/2  + 5/8 + 7/8     Convert to a common denominator
= 2/8 + 3/8 + 4/8 + 5/8 + 7/8
= (2   + 3     + 4    + 5     + 7)/8
 = 21/8                                        Convert to a mixed number
= (16 + 5)/8
=  2  +  ⅝
= 2⅝  
 
        
             
        
        
        
Answer: The answer is the first bubble
Step-by-step explanation:
1. When you identify the pairs you get: { ( -5,-4), (-1,5), ( -5,3) , (7,8) }
2. When figuring out whether or not it is a function, you have to see if there are any same y values. If there is no y values that are the same, then the relation is a function.
3. This relation is a function.
* Also, if you have a relation that has the two or more of the same x values, the relation is still a function no matter what.
 
        
             
        
        
        
Answer:
16, see below :)
Step-by-step explanation:
Hello!
We can use the pythagorean theorem because one of the angles is 90 degrees. According to the theorem, a^2 + b^2 = c^2
a is 12, b is unknown, and c is 20
Now we use the theorem
12^2 + b^2 = 20^2
144 + b^2 = 400
b^2 = 256
b = sqrt(256)
b = 16

Answer:
32 cups
Step-by-step explanation:
To find the total number of cups, we have to convert the measures that are not in cups to cups and add
1 quart  = 4 cups
4 quarts = 4 x4 = 16 cups
1 pint = 2 cups
6 pints = 2 x 6 = 12 pints
total number of cups = 16 + 12 + 4 = 32 cups
