6th-grade math, help me please:)

1. b) 1/4

2. c) 70

Step-by-step explanation:

1. There is 100% in a whole and you are trying to find 25%, so if you multiply 25 by 4, you get 100, therefore, 25% is the same as 1/4

2. 50% is half of 100%, so you need to find half of 140. Half of 140 is 70.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
