Answer:
For Skyhigh : 40 friends 
For Jump it up : 90 friends 
Step-by-step explanation:
Given that :
Maximum spending = $250
SKY HIGH FEES :
Party set up fee = $50 ; Amount paid per person = $2
JUMP IT UP FEES :
Party set up fee = $70 ; Amount paid per person = $2
THEREFORE, the inequality statement to obtain the number of friends for eack trampoline center goes thus:
Party setup fee + Number of persons * fee per person ≤ maximum spending 
SKY HIGH:
50 + 5x ≤ 250
5x ≤ 250 - 50
5x ≤ 200
x ≤ 200/5
x ≤ 40
Hence, 
Skyhigh can accommodate 90 friends Given the conditions
JUMP IT UP:
70 + 2x ≤ 250
2x ≤ 250 - 70
2x ≤ 180
x ≤ 180/2
x ≤ 90
Jump it up can accommodate up to 90 friends Given the conditions.
 
        
             
        
        
        
Answer:
I believe it is A
Step-by-step explanation:
Because if you take a point go up 1 and over 2 you get your next point. Rise over run would be 1/2 so the constant of proportionality would be 1/2 or .5

Answer:
3 times
Step-by-step explanation:
heaviest : 9/10 kg.. 0.9kg
lightest : 3/10 kg.... 0.3kg
0.3/0.9 = 1/3
 
        
             
        
        
        
Check the pictures below.
if we knew the roots/solutions of the equation, we can set h(s) = 0 and solve for "s" to find out how many seconds is it when the height is 0.
if you notice in the first picture, when f(x) = 0, is when the parabola hits a root/solution or the ground, for David he'll be hitting the water surface, and the equation that has both of those roots/solutions conspicuous is
h(s) = -4.9(s - 2)(s + 1).
