Answer:
Wm = 43.2 pounds
Step-by-step explanation:
If the ratio of the weight of an object on Mars to its weight on Earth is 9 to 25, this means that what on Mars weighs 9 units on earth weighs 25 units, therefore:
Data
ratio = 9/25
Weight on Mars (Wm) = ?
Weight on Earth (We) = 120 pound
Wm = (9/25)*120 pound = 43.2 pounds
Answer:
53
Step-by-step explanation:
3x +17= 7x-31
17+31 = 7x-3x
48 = 4x
48/4= x
12=x
x=12
KL= 3x+17= 7x+31
using KL= 3x+17;
KL= 3(12) +17
KL = 36+17
KL=53
Answer:
x = 6.5
Step-by-step explanation:
In order to solve this problem, you need to use trigonometry (sin, cosine, tangent).
Sin = opposite/hypotenuse
Cosine = adjacent/hypotenuse
Tangent = opposite/adjacent
We need to use tangent in this case because 10 is the opposite side from the 57° angle, and x is right next to it, making it adjacent. So, our equation would look like this:
tan (57)° = 10/x
Multiply both sides by x
x (tan (57)°) = 10
Divide both sides by tan (57)°
10 / tan (57)° = 6.49408 = 6.5
