Answer:
135 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =  h(a + b)
 h(a + b)
where h is the height and a, b the parallel bases
Here h = 9, a = 13 and b = 17 , thus
A =  × 9 × (13 + 17)
 × 9 × (13 + 17)
    = 0.5 × 9 × 30
    = 135 cm²
 
        
             
        
        
        
Isosceles triangle because it has two equal sides
        
             
        
        
        
48 cups because there are 8 cups in a bottle and 8 times 6 is 48
        
             
        
        
        
Answer:

Step-by-step explanation:
You have to use the property of quotient of powers, you subtract the power of the fraction denominator from the numerator 
 
        
                    
             
        
        
        
The first thing we must keep in mind is the following unit conversion:
 
 We have then that for 35 gigabytes: 
 Part A:
 Part A:
 For this case we make the following rule of three:
 2000 bytes --------------> 1 page
 35*10^9 bytes ----------> x
 From here, we clear x: 
 Part B:
 Part B:
 Then, the number of 500-page books is:
