Grace got a haircut for $26.95, bought three shirts on sale for
$18.50 each and a pair of jeans for $48, and purchased two cds
for $18.50 each. round each amount to the nearest ten dollars to
find a reasonable estimate of how much grace spent.
oa) $90
ob) $130
oc) $180
od) $210

I got 132, but since you're rounding it would be B. $130 ...

Step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
