Answer:
32.5
Step-by-step explanation:
The measure of an arc of a circle is half the measure of the angle that is created when two chords from the endpoints of the arc intersect on the circumference of the circle, so 65/2 = 32.5.
Take the # in the last week and times it by 3.5 than you should get the next week. ex: if you wanted to find the 9th week you could do 84 times 3.5 8 times
1.)100+80+7+0.5+0.04 or you could do it like 2.)1x100+8x10+7x1+5x0.1+4x0.01
