Answer: they are 3 miles apart
Step-by-step explanation:
Answer:
4.5
Step-by-step explanation:
∠BAC ~ ∠EDF means that the triangles are similar. So the legs of the triangle share the same proportions, even if the sizes are different.
Since they share the same proportions, the same operations can be performed on each base to find the area.
The answer can be found with the knowledge that the area of a triangle is half of the height * width. You know the width of ∠BAC is 4, and the area is 8, so 16 (the area doubled) / 4 is the height. The width and height of ∠BAC are the same, and since the proportions are also the same, the width and height of ∠EDF are both 3. So the area is the width (3) times the height (3) divided by 2.
3*3 = 9
9/2 = 4.5
So the area is 4.5
What variable can you give the problem?
My answer to the problem is as follows:
Expressed as an absolute value.
<span>
The difference between the actual length, x, and the specification, 43.6, can be no more than 0.1 </span>
<span>
|x - 43.6| ≤ 0.1 <–––––
</span>
<span>The 43.6 is the target length, and the tolerance of 0.1 is how far off from the target is acceptable.</span>
0.25 represents the slope of the line. For every 1 unit it goes up, it goes 4 to the right.
