Answer:
36 dream catcherss
Step-by-step explanation:
Jane's production rate:
1 dream catcher
6 days
Zena's production rate:
1 dream catcher
4 days
Production rate when working together:
1
6
+
1
4
=
5
12
. This ratio means it will take 12 days to make 5 dream catchers.
Set up a ratio for 15 dream catchers.

d
→ 5d = (12)(15) → 5d = 180 → d = 36
We can calculate for the slope of the line using the
formula:
m = (y2 – y1) / (x2 – x1)
From the given values:
m = (4,000 – 10,000) ft / (15 – 0) min
m = -400 ft/min
This means that the altitude is decreasing by 400 ft per
minute.
> The slope is –400 . This means that the helicopter
descends 400 ft each minute.
Because the route forms an isosceles right triangle, two legs of the triangle are equal.
There will be two angles, equal to 45°, and a 90° angle as shown in the figure below.
The distance from Old Mill is the same as the distance from Clarksville to Hamilton, equal to 48 miles.
Let x = distance between Old Mill and Hamilton.
By definition,
cos 45° = 48/x
or
x = 48/cos 45° = 67.882 mi
Answer: 68 miles (nearest mile)
