Answer:
3a. 8t + 12c = 72
3b. t + c = 7
Step-by-step explanation:
number of tapes is t
number of Cds is c
so 8t + 12c = 72
and t + c = 7
so t = 7 - c
replace t = 7 - c in to the first equation
8(7 - c) + 12c = 72
56 - 8c + 12c = 72
4c = 72 - 56 = 16
c = 4
if c = 4, then t = 7 - c = 7 - 4 = 3
B. 60 m is the height of the triangle
Answer:
0.0098 < 0.01935 < 0.02 < 0.14999 < 0.1589
C, because half of 50 is 25 therefore since it has landed on the head 28 which is a little bit more means the answer is gonna be a little more than 50%
