Answer:
The angle is 1/4 the circumference is the arc
Step-by-step explanation:
To solve this, we are to set up a fractional relation between the central angle subtended by the arc and the total angle subtended by the circle.
At this point, we can note that the circumference of a circle actually subtends an angle of 2π radians at the center.
To express the angle subtended by the central angle [angle at the centre of the arc] as a fraction of the total circle, we do this:
The central angle of arc / total angle at the centre of the circle
= π/2 ÷2π
=
Therefore the angle is 1/4 the circumference is the arc
Answer:
The ratio of girls and boys = 9/7
Step-by-step explanation:
32 members there are 18 girls
so boys = 32 - 18 = 14
The ratio of girls and boys = 18/14 = 9/7
Answer:
Yes, this relation is a function.
Step-by-step explanation:
It is a function because every input (left side) only has one output (right side). It doesn't matter if an output has multiple inputs. As long as an input has only one output, it is a function
Ex: 3 = 8 & 7 NOT an input
4 & 3 = 8 AN input
The answer is _________
9*4=36
9*7=63
7*4=28
9*4=36
9*7=63
7*4=28
Now add the numbers all up. You get <span>254, </span>
The independent variable would be the percent rates/unemployment rates because they change. The dependent variable would be the years... i think
