Answer:
m = 3.5
Step-by-step explanation:
So here we will just Cross-Multiply;
2(m) = 9(3)
2m = 27
Divide both sides by 2;
m = 13.5
The statement which best compare the mold growth rates is: C. the mold growth rate of the banana bread was half the mold growth rate of the whole wheat bread.
<h3>How to compare the mold growth rates?</h3>
First of all, we would determine area of mold growth B(t) on the piece of banana bread by using this equation:
B(t) = 20(1.06)^t
At t = 1, we have:
B(t) = 20(1.06)^1
B(t) = 21.2 mm².
At t = 2, we have:
B(t) = 20(1.06)^2
B(t) = 22.47 mm².
At t = 3, we have:
B(t) = 20(1.06)^3
B(t) = 23.82 mm².
At t = 4, we have:
B(t) = 20(1.06)^4
B(t) = 25.25 mm².
Now, we can compare the mold growth rates by using this expression:
B(t) = xW(t)
x = B(t)/W(t)
x = 21.2/40.8
x = 0.5.
At t = 2, we have:
x = 22.47/41.62
x = 0.5.
At t = 3, we have:
x = 23.82/42.45
x = 0.5.
At t = 4, we have:
x = 43.30/25.5
x = 0.5.

Answer:
So we must determine the distance between our two given points and that can be found using the distance formula .
Plugging the values into the equation and solve
Therefore, our final answer is that the distance is 16.125 units
