Answer:
5.02 pounds
Step-by-step explanation:
y = k*x
Where,
y = weight of a object on Jupiter
x = weight of the object on earth
k = constant of proportionality
An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter.
y = k*x
378.2 = k*150
378.2 = 150k
k = 378.2/150
= 2.5213
Approximately k = 2.52
determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth
y = k*x
12.64 = 2.52*x
12.64 = 2.52x
x = 12.64 / 2.52
= 5.0159
Approximately x = 5.02 pounds
Answer:
x = 3
Step-by-step explanation:
You can treat x and 2x+1 just as though they are real numbers.
So f(2x+1) = 3(2x+1) - 5 = 6x + 3 - 5 = 6x - 2
In the above, I made use of something called the distributive law which says that if a,b and c are real numbers, then a(b+c) = ab + ac.
Answer:
AC = 12.5 cm
Step-by-step explanation:
use cosine law c^2 = a^2 + b^2 − 2ab cos(C)
c^2 = 6^2 + 10^2 - 2(6)(10)(cosin100)
c^2 = 156.84
c= √156.84
c= 12.5 cm
The cosine rule is used when we are given either three sides or two sides and the included angle.
