Question:
Obtian the equation that can be used to solve for c
Answer:
Sin50 = 3/c
Step-by-step explanation:
A triangle showing the information given has been attached below for clarity :
Using trigonometry :
AC = 3 = opposite side of angle 50°
AB = c = hypotenus
Using the sine relation of a right angled triangle :
Sin θ = opposite / hypotenus
θ = 50°
Sin 50° = 3 / c
Sin50 = 3/c
Answer: 255,000 inches; 4.0256121212 miles
Step-by-step explanation:
8,500*30
= 255,000 (inches total)
There are 63,360 inches in a mile
255,000/63,360
= 4.02462121212
Answer:
52 years
Step-by-step explanation:
Let
Your age = x
3 times your age = 3 * x
= 3x
The equation can be written as:
400 - 3x = 244
400 - 244 = 3x
156 = 3x
Divide both sides by 3
x = 156/3
x = 52
Therefore,
Your age is 52 years
The answer is 315. Since the two numbers vary directly, when one of them triples, the other must do the same! :)
Being y the total fare and x the number of miles
