570 adults and 215 children
Step-by-step explanation:
did this assignment and got it right
5a + 2c = 3280 where a is adults and c is children
subtraction eliminates c, find a
3a + 0 = 1710
a = 1710/3
a = 570 adult and then you have to subtract 785-570= 215 children
Answer:
25.9 feet per second.
Step-by-step explanation:
For the first 14 seconds, the change in elevation was –65×14= –910 feet.
For the remaining 6.5 minutes, the change in elevation was –1,470×6.5 = –9,555 feet.
The overall change in elevation was –910+ –9,555= –10,465 feet.
The total number of seconds was
6.5×60=14+390=404 seconds. The Average change in elevation was −10,465÷404=25.9 feet per second.

0=44-25t-5t^2
t^2+2t-8=0
(t+4)(t-2)=0
t=-4 (not a solution) or t=2
Answer: after 2 seconds
X is 90°
A triangles angles add up to 180° so
180 - 47 - 90 = y
180 - 137 = y
y = 43°
