Answer:
the third one
Step-by-step explanation:
9 to the power of 4 is 9 multiplied by it's self 4 times
 
        
             
        
        
        
6.5 x 10 to the 3rd power
remember the base must be less than 10 and greather or equal to 1
        
                    
             
        
        
        
Answer:
A) This is correct. The angles of <em>AEB </em>are the angles of <em>DEC. </em>This means that this is true. 
B) This is incorrect. This triangle is NOT an isosceles triangle. The angles of an isosceles triangle are supposed to be about 36° for the top angle, and 72° for the other two angles. (At least this is what I was told) 
Hope this helps :)
-wait. .___. they both might be true. 
According to G oogle: "All the three angles situated within the isosceles triangle are acute, which signifies that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°, which means we can find out the third angle of a triangle if the two angles of an isosceles triangle are known."
 
        
             
        
        
        
Answer:
Given:
I usually walk from home to work. This morning, I walked for 10 minutes until I was halfway to work. 
I then realized that I would be late if I kept walking. 
I ran the rest of the way. I run twice as fast as I walk. 
Find:
The number of minutes in total did it take me to get from home to work
Step-by-step explanation:
Had I kept walking, the second half of my trip would have taken 10 more minutes. 
By doubling my speed for the second half of my trip, 
I halved the amount of time it took me to finish. 
So, the second half of my trip took 5 minutes, for a total trip time of  10+5 = 15 minutes.
The number of minutes in total did it take me to get from home to work is 15 minutes.
 
        
                    
             
        
        
        
Let's calculate r of this G.P: (-20)/(4) = - 5(100)/(-20) = - 5So r = -5
The formula to find the nth term of a GP is;
a(n) = a(r)ⁿ⁻¹
<u />a₆ = a(r)⁶⁻¹
a₆ = 4(-5)⁵ = -12500<u />
