Answer:
(C)c= 
f
Step-by-step explanation:
Clare uses 
cups of flour to make 4 cakes.
It means she uses 1 cup of flour to make 
cakes.
Let us simplify that expression first for future use.
Therefore, Clare uses 1 cup of flour to make cakes.
If Noah follows the same recipe,
He uses f cups of flour to make c cakes
Using Ratio Method
→ Name : Cup : Cake
→ Clare : 1 :
→ Noah : f : c
By using cross multiplication
c X 1 = f
c= f
The equation c= f represents the relationship between c and f
Answer:
part a is A and E
Step-by-step explanation:
I had token the test
Hi there!
To solve this problem, we need to simplify.
2/3x = 12
To isolate x, we should multiply both sides of the equation by the reciprocal of 2/3 to make x equal to a value:
Reciprocal of 2/3 = 3/2
x = 12 * 3/2
x = 18
Hope this helps!
Answer:
9990 years
Step-by-step explanation:
The exponential function with given values filled in can be solved for the unknown using logarithms.
__
Q(t) = 12 = 36e^(-0.00011t)
1/3 = e^(-0.00011t) . . . . . . divide by 36
ln(1/3) = -0.00011t . . . . . . take natural logs
t = ln(1/3)/(-0.00011) . . . . divide by the coefficient of t
t ≈ 9990 . . . years
