Answer:
36
Step-by-step explanation:
You add all of them together which is 9
Then you take the combination of A to C
Which is 9C2
Answer:
A = number of adult tickets
S = number of student tickets
1033 = total tickets sold
A + S = 1033
5A = money collected for adult tickets
S = money collected for student tickets
2265 = total money collected
5A + S = 2265
two equations and two unknowns:
5A + S = 2265
A + S = 1033
subtract 2nd equation from 1st and solve for A:
4A = 1232
A = 308
Plug in value for A in 1st equation and solve for S:
A + S = 1033
308 + S = 1033
S = 725
First step is square root both sides leaving with
x-6=+/-3
closest one is A
answer is A
Answer:
S(t) = -4.9t^2 + Vot + 282.24
Step-by-step explanation:
Since the rocket is launched from the ground, So = 0 and S(t) = 0
Using s(t)=gt^2+v0t+s0 to get time t
Where g acceleration due to gravity = -4.9m/s^2. and
initial velocity = 39.2 m/a
0 = -4.9t2 + 39.2t
4.9t = 39.2
t = 8s
Substitute t in the model equation
S(t) = -49(8^2) + 3.92(8) + So
Let S(t) =0
0 = - 313.6 + 31.36 + So
So = 282.24m
The equation that can be used to model the height of the rocket after t seconds will be:
S(t) = -4.9t^2 + Vot + 282.24
