Answer: 1,596 cubic cm. To find the volume, you need to multiply all the three sides given.
Step-by-step explanation:
12cm * 7 cm* 19cm = 1596 cm^3
 
        
             
        
        
        
Y = 2x +13
We know the slope to be 2 because lines that are parallel have the same slope. Then we can solve using slope-intercept form and  the known point. 
y = mx + b ----> Input known values
7 = (2)(-3) + b ---> Multiple
7 = -6 + b ----> Subtract 3 from both sides
13 = b
Now we can use the y-intercept found and the slope to write the equation above. 
        
                    
             
        
        
        
we know that


To find how long are  sections placed end to end
  sections placed end to end
Multiply the number of sections by the length of one section
so


therefore

Answer:
0.292
Step-by-step explanation:
Combinations can be used to solve the following problem.
We are choosing 5 widgets from 25 = ²⁵C₅
We want to select zero widgets from defective widgets = ⁵C₀
From the 20 non-defective widgets we want to select 5 = ²⁰C₅
So the probability is:
P = ( ⁵C₀ * ²⁰C₅) / ²⁰C₅
P = (1 * 15504) / 53130
= 15504/ 53130
=0.292 ..
 
        
             
        
        
        
Answer:
1 9/16
Step-by-step explanation:
F(1/4) means u plug in 1/4 for x 
so the equation would be 
f(1/4)=1/4^2+2 1/4 + 1
f(1/4)=1/16+1/2+1
f(1/4)= 9/16 +1 
f(1/4)= 1 9/16
its not nine teen its one and 9 over 16 just clarification
