Answer:
anything less than 133 would be true
Step-by-step explanation:
35 ≥ 0.15m + 15
solve for m
subtract 15 from both sides
20 ≥ 0.15m
divide both sides by 0.15
133.33 ≥ m
m cannot be more than 133 minutes

Answer:
7/16
Step-by-step explanation:
There are a total of 32 marbles. Of these marbles, 14 are not blue. So the probability is 14/32, or 7/16.
Remark
This is a trig question. You need two function (Tan(C) and Cos(C)
Tan(C)
this will give you the value for BA
Tan(C) = BA / BC
Givens
C = 40 degrees
BC = 10
tan(C) = AB/BC
Tan(40) = AB / 10
0.8391 = AB / 10 Multiply both sides by 10
10*0.8391 = AB
AB = 8.391
Cos(C)
Cos(C) = BC/AC
BC = 10
C = 40 degrees.
Cos(C) = 0.76604
0.76604 = 10/AC Multiply both sides by AC
0.76604 * AC = 10
AC = 10/0.76604
AC = 13.054
