Answer:
1) 90 mi
2) 4 inch
Step-by-step explanation:
1)
Given that the distance between Fairview and Abbots Rise on the map = 5 in
Scale of the map = 1 in: 18 mi
i.e. 1 inch on map is equivalent to an actual distance equal to 18 mi between the cities.
Given that the map has a distance of 5 inches.
Therefore, the actual distance between the cities = 5 
18 = <em>90 mi</em>
<em></em>
2) A particular satellite is 12 ft wide.
Model's scale = 1 in : 3 ft
i.e. 1 inch on map is equivalent to actual distance of 3 ft.
OR
3 ft of actual distance = 1 in on map
1 ft of actual distance = 
in on map
12 ft of actual distance = 
Answer:≥2
Step-by-step explanation:
First, we need to translate the problem into algebraic expressions and equations:
[length][is][ten inches more than][twice the width]
⟹[][=][10+][2×]
⟹=10+2
==(10+2)()=22+10
[Area][is at least][28]
[][≥][28]
⟹≥28
Putting these together, we have a quadratic inequality:
22+10≥28
The most straightforward way [I know of] to solve this is to compare to zero, find the roots, and go from there:
22+10−28≥0
⟹2+5−14≥0
Finding the zeros using your favorite method — factoring, quadratic formula, etc. — yields zeros of ={−7,2} .
Since the width of the rectangle can’t be negative, our solution involves =2 . The graph of the quadratic function is concave up (due to the positive leading coefficient), meaning the function is non-negative for ≤−7 or ≥2 — giving us our solution, ≥2 !
