2100 ones if I am thinking about this right. hope it helps
The equation computed simply shows that the number of months will be C. 9 months.
<h3>How to solve the equation</h3>
From the information given, the equation 8m+3=75 models how many months, m, it takes a tree to reach a height of 75 inches after being potted.
Therefore, the number of months will be calculated thus:
8m + 3 = 75
8m = 75 - 3
8m = 72
m = 72/8
m = 9
The correct option is 9 months.

First off, let's change the mixed fraction to "improper", and do the division then.
Downstream DATA:
distance = 12 miles
time = 2 hours
rate = 12/2 = 6 mph
----------------
Upstream DATA:
distance = 12 miles
time = 4 hrs
rate = 12/4 = 3 mph
----
Equations:
Downstream: b + c = 6
Upstream::: b - c = 3
------
Add to get:
2b = 9
b = 4.5 mph (speed of the boat in still water.)
-----
Solve for "c":
b + c = 6
4.5 + c = 6
c = 1.5 mph (speed of the current)
The answer is 1.5 mph
Answer:
Step-by-step explanation:
Given
--- Volume
--- Diameter
Required
Find the volume
First, we calculate the radius, r
Substitute 23 for D
Substitute 11.5 for r in
