Answer:
1/2
Step-by-step explanation:
First count how many sections aren't red or green: 2 yellow + 2 blue
Now we know that the total number of sections is 8.
So out of those 8 sections, 2 yellow + 2 blue aren't red or green.
That is, 4 out of the 8 sections aren't red or green.
This can be expressed as a fraction: 4/8
Now we simplify the fraction by dividing by 4 on the top and bottom: 1/2
 
                                
             
                    
              
              
                
                
Answer:
1/2
(This is assuming all sectors are congruent)
Step-by-step explanation:
Well the other two colors that aren't red or green is blue and yellow.
There are 2 blues and 2 yellows.
There are 8 sections altogether.
We are asked to find the probability that our spinner will land on blue or yellow so we do (blue+yellow)/all = (2+2)/8=4/8=1/2.
This probability was assuming all sectors were congruent sectors.

Given: 
t = 1/2 √v
v = speed of object meters per second
t = 3 seconds
3 = 1/2 √v
3 * 2 = √v
6 = √v
6² = √v²
36 meters = v
v = 36 meters per second
        
             
        
        
        
Given that:
f(x) = -2x²-2x+10
f(2) = -2(2)²-2(2)+10
 = -2(2*2) - 4 + 10
 = -2(4) - 4 + 10
 = -8 - 4 + 10
 = -12 + 10
 = -2 Ans.

Answer:
5x5 = 25
5x0,5 = 2.5
5x0,03 = 0.15
Adding them makes: 25+2.5+0.15 = 27.75
 
        
             
        
        
        
Answer:
y=5 degrees
Step-by-step explanation:
It is an isosceles triangle so that means that there are two angles that equal 75, so that means the third side with 4y + 10 is equal to 30 degrees. 
4y+10=30
4y=20
y=5 degrees
