Answer:
200(−91x+2)
Step-by-step explanation:
Answer:
k = 9
Step-by-step explanation:
n = 3, so substitute 3 for n in the equation
k = 3(3)
k = 9
Answer:
Option D
Step-by-step explanation:
Formula for the surface area of rectangular prism = 2(lb + bh + hl)
Here, l = Length of the prism
b = Width
h = Height
If l = 25 cm, b = 12 cm and h = 20 cm
Surface area of the rectangular prism = 2(25×12 + 12×20 + 20×25) cm²
Therefore, Option D will be the correct option.
Answer:
41.04 g/L
Step-by-step explanation:
The relationship is modeled by the following function:
S(t) = 500*e^(-0.25*t)
where t is time elapsed after the dilution begins (in hours) and S(t) the concentration of salt in the tank (in g/L)
Replacing with t = 10
S(t) = 500*e^(-0.25*10)
S(t) = 41.04 g/L
This is a one-step equation. All you need to do is multiply the 2.5 over to the 20 to get x by itself.
x=50
Hope this helps!
