Answer:
414 tickets!
Step-by-step explanation:
If there were sold 92 adult tickets, and for every two of them, 7 student tickects are sold, we have the following:
92 / 2 = 46
Multiply by 7.
46 * 7 = 322 student tickets.
322 students tickets + 92 adult tickets = 414 tickets in total.
Answer:
Bl^2+4Bl*Fh
Step-by-step explanation:
I'm not quite certain what "draw a net" means here. But for part b, we are doing the formula. The bottom part is a square(assumingly so take this with a grain of salt), thus making the base equal to 3*3 cm or 9 cm^2. The triangular faces are each 3*2.24 cm or 6.72 cm^2. We then multiply this by 4 to get 26.88. Thus, the equation is Bl^2(Base length squared)+Bl*Fh(Face height, I forgot the official name sorry about that)*4 for part b.
Answer:
1.31 miles of the race course are uphill
Step-by-step explanation:

Hope this helped :)
Using Heron's formula:
A = √(p(p-a)(p-b)(p-c)) where a,b,c are the sides of the triangle and p is half the perimeter.
The answer is B. 149.4 square units.
