Let the speed of plane in still air be x and that wind be y
therefore:
x+y=490
x-y=390
next we solve for the values of x and y, first we add the above equations. This will give us:
2x=880
x=880/2
x=440 miles per hour.
substituting the value of x in one of the equations and solving for y we get:
440+y=490
y=490-440
y=50 miles per hour
Answer:
Hi there!
6/15 is the probability that the marble is black!
Step-by-step explanation:
Oki, so lets's find the total number of marbles first!
8 + 6 + 1 = 14 + 1 = 15
And just turn it into a fraction!(very simple and easy)
6/15
- 2.65 × 10⁻²
5.3 × 10⁴
- 3.4 × 10³
1.01 × 10⁵
6.71 ×10⁻³
Answer:
x = 12.2
Step-by-step explanation:
sin theta = opp / hypotenuse
sin 55 = 10 /x
Multiply each side by x
x sin 55 = 10
Divide each side by sin 55
x = 10 / sin 55
x =12.20774589
Rounding to the nearest tenth
x = 12.2
