Answer:
1/5
Step-by-step explanation:
formula is y = kx
k is the constant of proportionality
when x is 5 y is 1
when x is 10 y is 2
so 1 = k * 5
so k = 1/5
Answer:
n = -3
Step-by-step explanation:
-5 = -8 - n
3 = -n
-3 = n
Answer:
3
Step-by-step explanation:
6L/1.89L =3.174 bottles so 3 bottle is almost 6L
Answer:
42.875
Step-by-step explanation:
First you find the x-intercepts and the vertex of the equation.
(-5, 0), (-2, 0), (-3/2, 49/4)
You use those coordinates to find the sides of the triangle and then you use the lengths to find the semiperimeter.
Lastly, you use Heron's formula to compute the area.
A(n) = 16 + 8(n - 1)
A(16) = 16 + 8(16 - 1)
A(16) = 16 + 120
A(16) = 136 people
