Answer:
6
Step-by-step explanation:
There are only 6 significant digits because in total there are 9 digits. We do not need the first 2 0's, so now we only have 7 digits. But the question is do we really need the last 0? The answer is no. No, you do not need the last 0 because we already know that it's .0049, and the 0 is just an extra. 
So without all the insignificant 0's, the number would look like this:
13.0049
 
        
             
        
        
        
1) Answer: A
because trangles RST is similar  to VUT as:
<RST=<VUT=55 (Angle)
<RTS=<VTU=90 (it seems right angled)  Angle
So by AA similarity...(two angles similarity is enough)
2) Answer:B
y+z=x because exterior angle of a triangle (which is x) must be equal to sum of non-adjacent (y and z) interior angles.
3) Answer: A should be right choice. Step 1 is wrong here which is,
m<m + m<n + m<p=180 (wrong)
It should be:
m<m + m<n + m<0=180 (right)
 
        
             
        
        
        
Answer: Each have to sell 91 candy bars to have the same amount of money.
Step-by-step explanation: Suppose x represents the amount of candy bars.
Team A already have $165 and they are selling each candy bar for $2. The mathematical equation that represents the amount of money they have is
A: 165 + 2x
Team B initially has $74 and will sell each candy bar for $3. Then, the mathematical equation representing their amount of money is
B: 74 + 3x
So, to have the same amount of money:
165 + 2x = 74 + 3x
x = 165 - 74
x = 91
<u>Teams A and B will have the same amount of money when each of them </u><u>sell 91 candy bars</u>.
 
        
             
        
        
        
Answer:
-4
Step-by-step explanation:
According to the rules of the distributive property, you have to multiply the term outside of the parentheses with the terms inside the parentheses first.
1. 2(-5)=-10    
2. 2(3)=6
The terms that we have are now -10 and 6. Add them together to get the final answer.
-10+6=-4
