Answer:
A 100 lb person will weight 40 lb on Mars
Step-by-step explanation:
Given:
Weight on Mars directly varies as its weight on earth.
Let weight on Mars be = 
Let weight on Earth be = 
Its known that:
∝
Thus
where 
is constant of proportionality.
when 
, then 
thus, we have
dividing both sides by 95.
∴ 
Thus when 
, would be calculated as
∴ 
(Answer)
∴ A 100 lb person will weight 40 lb on Mars.
Largeur = x
longueur = 4 x
2 ( x + 4 x) = 20
2 x + 8 x = 20
10 x =20
x = 2
largeur = 2 et longueur = 8
Answer:
12 3/4, 12.7, 12/5
Step-by-step explanation:
12 3/4 = 12.75
12 3/5 = 12.6
First, you find how many total feet Rick can afford. To do this, you do 2000/20 which equals 100. Then, you write your inequality. 100 is less than or equal to 2x+6. Next, you solve your inequality. You subtract 6 on both sides to get 94 equals 2x. To solve this, you divide by 2 on both sides. In this scenario, x stands for the width.
Step-by-step explanation:
N:2 = 15:5
N\2 = 15\ 5
Now cross multiply,
5N = 30
N = 6
