Answer:

Each class should get 17 tickets. 4 tickets will be left over.

Step-by-step explanation:

157/9=17.444... -> 17 per class

17 x 9 = 153

157-153= 4 left

Joseph has 1/2 of a sub left after lunch. He eats 1/4 of this amount for snack. what fraction of a whole sub did Joseph eat fo

TiliK225 [7]

Answer:

Step-by-step explanation:

I believe the answer would be 1/4 of the sub. Because they asked about the whole sub. And it says he ate 1/4 of the amount of that half of the sub for snack. So out of the whole sandwich it would be 1/4!

If it’s not the answer your looking for you can take it off...

The measurement of an arc in degrees is the same as the central angle. We must assume that the central angle is the measurement given.
$\overset{\LARGE{\frown}}{AB}$ = 49

To find the next one you need to find the measurement from B to C, the arc that is over 180 degrees. Maybe you could put another letter between B and C so that we could refer to that top arc greater than 180 degrees. Call the point you inserted D.

$\overset{\LARGE{\frown}}{BDC}$ = 360 - 49 - 107 = 204
$\overset{\LARGE{\frown}}{ABC}$ = $\overset{\LARGE{\frown}}{BDC}$ + $\overset{\LARGE{\frown}}{AB}$

Arc(ABC) = 204 + 49 = 253

Arc(BAC) = Arc(BC) + Arc(AB)
Arc(BAC) = 107 + 49
Arc(BAC) = 156

Arc(ACB) = 107 + 204 = 311
