Answer:
true
Step-by-step explanation:
Pam saved 40
her bro saves 100
let us take this as ration 40 is to 100 which can also be written in fractional for like 40/100 now we simplify it how by dividing both by 20 so (40/20)/(100/20) which will give 2/5 which can be written as 2 is to 5 so this is true
 
        
                    
             
        
        
        
In the problem with the white circle, x=100, in the problem with the blue circle, x might equal 165, but I'm not entirely certain.  But I am certain about the first one.
        
             
        
        
        
Let's start by imagining a rock being thrown to the air.
Let's say that going up is the positive direction and so, going down is the negative.
The acceleration is pointing down (because of gravity) so it's always negative. While the rock is going up, it's velocity/speed is positive, but the acceleration is negative.
While the rock is going down, both acceleration and speed are negative.
This shows that the first statemente is true, but the second is false.
You can also think that if you define going DOWN as the POSITIVE direction, you can have both positive acceleration and speed, or positive acceleration and negative speed.
        
             
        
        
        
The answer would be 400$. This is because 40 x 10 = 400.
