To solve this problem, let us say that the action of
totally painting a small house is called “1 job”. Therefore the rates of each
person in painting the small house are:
Bill = 1 job / 3 days = 1 / 3
Sharon = 1 job / 4 days = 1 / 4
Wilber = 1 job / 5 days = 1 / 5
Therefore the total rate is calculated by simply adding
the rates of the three.
(1 / 3) + (1 / 4)
+ (1 / 5) = 1 / x
where x is the number of hours it take if all them paint
together
Calculating for by multiplying both sides by 60:
60 [(1 / 3) + (1 /
4) + (1 / 5) = 1 / x]
(60/3) + (60/4) + (60/5) = 60 / x
20 + 15 + 12 = 60 / x
47 = 60 / x
x = 60 / 47 hours
Answer:
60/47 hours
Gravity is inversely proportional to the square of the distance.
In English:
Your weight at the Earth's surface and your weight 850 miles above the Earth's surface decreases by a factor of
(4,750 / 3,900) ^ 2 =
<span>
<span>
<span>
1.483399080
</span>
</span>
</span>
So your weight would decrease by (your weight /
<span>
<span>
<span>
1.483399080
</span>
</span>
</span>
)
If you weigh 180 pounds, at 850 miles above the Earth your weight is
180 /
<span>
<span>
<span>
1.483399080
</span>
</span>
</span>
which equals
<span>
<span>
<span>
121.3429362515

pounds.
The answer to this question is y = 2/3x + 5
