You and a classmate have a bug collection for science class. you find 5 out of every 9 bugs in the collection. you find 4 more bugs than your classmate. how many bugs are in the collection?

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed
