Answer:
h = 3v/b
Step-by-step explanation:
Here, we want to select the equation that solves for h
What this simply means is that we should make h the subject of the formula
Thus, we have 3 * v = bh
3v = bh
h = 3v/b
Let x the maximum speed of the plane and y be the speed of the wind.
We know that:
1)Distance = speed x time
2) if the head wind is y, then the resulting speed is x-y (against the wind)
3) if the tail wind is y, then the resulting speed is x+y (with the wind)
1) and 2): 2400 = (x-y).(6) or 6x-6y = 2400
1) and 3): 2400 = (x+y).(5) or 5x+5y = 2400
Hence the system of 2 equation:
6x - 6y = 2400
5x + 5y = 2400.
Solving it gives x = 440 mi/h and y = 40 mil/h
Then the speed of the plane with no wind is 440 km/h
Answer:
wow nice question but sorry can't answer
Step-by-step explanation:
Answer:
x > 3
Step-by-step explanation:
6x + 3 > 21 (Move the constant, +3 to the right hand side and change its sign)
6x > 21 -3 (Subtract 21-3)
6x >18 (Divide both sides by 6)
x > 3
It would be greatly appreciated if you gave me the brainlest
Amount after 19 years is $14,480 (Rounded off)
Nearest hundred dollars = $14,500
Step-by-step explanation:
Compute compound interest using the following formula: A = P(1 + r/n) ^ nt
A= Total amount value
P = principle amount invested
r = rate of interest
n = numbers of years invested
A = $9,400 r =2.3% n =19 years
A= 9400 (1+2.3÷19) ^ 19 = $14,480 (Rounded off)
Amount after 19 years is $14,480 (Rounded off)
Nearest hundred dollars = $14,500
