Answer:
Step-by-step explanation:
For women, the initial number is 6, constant rate of change is w, number of years is x.
<u>Find the rate of change and work out the required formula:</u>
- 10w + 6 = 391 ⇒ 10w = 385 ⇒ w = 38.5
<u>Formula:</u>
<u>Similarly for men, we get:</u>
- 10m + 25 = 410 ⇒ 10m = 385 ⇒ m = 38.5
<u>Formula:</u>
Answer:
2
Step-by-step explanation:
Ok, so if we know how much wire is needed for one outlet, we must figure out how many 18.25s fit into 50 ft of wire.
18.25*2=36.5
18.25*3=54.75 which is over 50 so it cannot possibly be more than 2.

Answer:
diameter = m - c
Step-by-step explanation:
In ΔABC, let ∠C be the right angle. The length of the tangents from point C to the inscribed circle are "r", the radius. Then the lengths of tangents from point A are (b-r), and those from point B have length (a-r).
The sum of the lengths of the tangents from points A and B on side "c" is ...
(b-r) +(a-r) = c
(a+b) -2r = c
Now, the problem statement defines the sum of side lengths as ...
a+b = m
and, of course, the diameter (d) is 2r, so we can rewrite the above equation as ...
m -d = c
m - c = d . . . . add d-c
The diameter of the inscribed circle is the difference between the sum of leg lengths and the hypotenuse.
