If each linear dimension is scaled by a factor of 10, then the area is scaled by a factor of 100. This is because 10^2 = 10*10 = 100. Consider a 3x3 square with area of 9. If we scaled the square by a linear factor of 10 then it's now a 30x30 square with area 900. The ratio of those two areas is 900/9 = 100. This example shows how the area is 100 times larger.
Going back to the problem at hand, we have the initial surface area of 16 square inches. The box is scaled up so that each dimension is 10 times larger, so the new surface area is 100 times what it used to be
New surface area = 100*(old surface area)
new surface area = 100*16
new surface area = 1600
Final Answer: 1600 square inches
The x-intercept is the point on the graph where it crosses the x-axis. It’s also the value of the x-coordinate when y = 0.
To find the x-intercept, set y = 0:
-5x + 1/5(0) = 15
-5x + 0 = 15
-5x = 15
Divide both sides by -5:
x = -3.
Therefore, the x-intercept is (-3, 0).

Answer:
To find the inverse interchange the variables and solve for y.
Step-by-step explanation:
f−1(x)=6x−53(1+x)
800+16x=720+21x
80+16x=21x
80=5x
X=16
So 16 hours :)
Answer:
1. Marcia
2. (I do not understand what this question is asking)
3. Marcia's estimation is closer
4. 690 people per year
Step-by-step explanation:
1. Marcia's estimation has a greater number of people because he estimated 600 people per year, while Adam estimated 2% of 12,500 (250 people per year).
2. (I do not understand what this question is asking)
3. marcias guess was 600 (600x50+12,500 = 42,500. 42,500 - 35,400 = 7,100) while Adam's guess was 250 per year (250x50+12,500 = 10,400). Therefore, Marcia's guess was closer to 35,400.
4. If Marcia adjusted her answer so that the population in Burbville was ACTUALLY going to be 34,500, she would need to adjust her estimation to 690 people per year.
Hope this helps! So sorry I couldn't understand question 2!
