Answer:
10 rows with 6 passengers per row
Step-by-step explanation:
Let x be the number of rows and y the number of passengers per row.
Then we can interpret the story as the following two equations:
xy=60
(x+2)(y-1)=60
Solving these two equations:
y=60/x
(x+2)(60/x-1)=60 (substitute y)
60 - x + 120/x - 2 = 60 (multiply by -x)
x² + 2x - 120 = 0 (factor)
(x-10)(x+12) = 0
x = 10
y = 60/10 = 6
and indeed 10 * 6 = 60 and also 12 * 5 = 60
$661.6-ish
$661.6432918 to be exact
Not sure if I preformed that correctly though
Answer:
Not function
Step-by-step explanation:
sin 40° / x = sin 90° / 35
x = (sin 40° x 35) / sin 90°
x = 22.498 m
