Answer:</h2>
a)
Venus: 81.9 pounds
b)
Earth: 144.7 pounds
c)
Uranus: 110.2 pounds
d)
Mercury: 48 pounds.
<h2>
Step-by-step explanation:</h2>
It is given that: when earth weighs 120 pounds.
Then
weight of : Mercury=45.6 pounds
Venus= 109.2 pounds
Uranus = 96 pounds
Jupiter= 304.8 pounds
a)
If Earth weighs= 90 pounds
when Earth weighs 120 pounds then weight of Venus= 109.2 pounds
If Earth weighs 1 pounds then weight of Venus= 109.2/120
i.e.
If Earth weighs 90 pounds then weight of Venus= (109.2/120)×90
i.e.
If Earth weighs 90 pounds then weight of Venus= 81.9 pounds
b)
Mercury: 55 pounds
When Mercury weighs 45.6 pounds then weight of Earth=120 pounds
Hence,
when Mercury weighs 1 pounds then weight of Earth=120/45.6 pounds.
when Mercury weighs 55 pounds then weight of Earth=(120/45.6)×55 pounds.
when Mercury weighs 55 pounds then weight of Earth=144.7 pounds.
c)
Jupiter: 350 pounds
When Jupiter weighs 304.8 pounds then weight of Uranus=96 pounds.
when Jupiter weighs 1 pounds then weight of Uranus=96/304.8 pounds.
when Jupiter weighs 350 pounds then weight of Uranus=(96/304.8)×350 pounds.
when Jupiter weighs 350 pounds then weight of Uranus=110.2 pounds.
d)
Venus: 115 pounds
When Venus weighs 109.2 pounds then weight of Mercury=45.6 pounds.
when Venus weighs 1 pounds then weight of Mercury=45.6/109.2 pounds.
when Venus weighs 115 pounds then weight of Mercury=(45.6/109.2)×115 pounds.
when Venus weighs 115 pounds then weight of Mercury=48 pounds.
