Answer:
(b) 0.5431
Step-by-step explanation:
The proportion of adult tickets sold is the ratio of the total number of adult tickets sold to the total number of tickets sold. Those totals are found on the bottom line of the table.
__
proportion = (adult tickets)/(total tickets) = 126/232 ≈ 0.5431
Approximately 0.5431 of the tickets sold were adult tickets.
In this question, it is given that the base radius is 2 , height is 6 and the value of pi is 3.14 .
And we have to find the volume of the cylinder, and for that, we have to use the following formula

Substituting the values of pi,r and h, we will get

There were 18 adults on the field trip. See, since 8x6=48, and there are 3 adults in each group, and there are 6 groups, there are 18 adults (6x3=18)
If you follow PEMDAS, multiplication would be first, so 3*2 is 6, then it's addition.
So 3*2=6 and 8*-16 is -128, then you add them both.
So 6+(-128) is equals to -122. YOU'RE WELCOME :D
