Answer:
48 sq inches
Step-by-step explanation:
Given that,
Ribbon used around a bulletin broard is 28 inches
The length of her board is 6 inches
Let B is breadth of her board. 28 inches is perimeter. The perimeter of rectangle is given by :
P = 2(L+B)
28=2(6+B)
14=6+B
B=8 inches
The area of a rectangle is given by :
A = L×B
A = 8×6
A=48 sq inches
So, the area of her board is 48 sq inches

Answer:
1 year
Step-by-step explanation:
The population can be modelled by the equation:
![P=P_0(1 + r)^{t}](https://tex.z-dn.net/?f=P%3DP_0%281%20%2B%20r%29%5E%7Bt%7D%20)
From the question, the initial population is
![P_0=19000](https://tex.z-dn.net/?f=P_0%3D19000)
The annual growth rate is r=0.04
We want to find how long it will take for that population to reach 43500.
We substitute the values to get:
![43500=19000(1 + 0.04)^{t}](https://tex.z-dn.net/?f=43500%3D19000%281%20%2B%200.04%29%5E%7Bt%7D%20)
![435=190(1.04)^{t}](https://tex.z-dn.net/?f=435%3D190%281.04%29%5E%7Bt%7D%20)
![\frac{435}{190} = (1.04)^{t}](https://tex.z-dn.net/?f=%20%5Cfrac%7B435%7D%7B190%7D%20%20%3D%20%281.04%29%5E%7Bt%7D%20)
![t = \frac{ \ln(2.289) }{1.04}](https://tex.z-dn.net/?f=t%20%3D%20%20%5Cfrac%7B%20%20%5Cln%282.289%29%20%7D%7B1.04%7D%20)
![t = 0.7965](https://tex.z-dn.net/?f=t%20%3D%200.7965)
To the nearest year, t= year
