Answer:
Let B have x days work:
A + B = 3 days
1/4 + 1/x = 1/3
1/3 - 1/4 = 1/x
1/12 = 1/x
x = 1 / (1/12)
x = 12
B takes 12 days

Answer:
2839.4 meters
Step-by-step explanation:
Given that:
Altitude = 1200 m
Using trigonometry :
The distance from point P to the airplane :
Using trigonometric relation :
Sin θ = opposite / hypotenus
Sin θ = altitude / x
Sin θ = 1200 m / x
Sin 25 = 1200 / x
0.4226182 = 1200 / x
x = 1200 / 0.4226182
x = 2839.4423
Distance from P to airplane = 2839.4 meters
Answer:
the answer is c because
Step-by-step explanation:
Answer:
x = 1/5(k-14)
Step-by-step explanation:
5x + 14 = k
Subtract 14 from each side
5x+14-14 = k-14
5x = k-14
Divide by 5
5x/5 = 1/5(k-14)
x = 1/5(k-14)
Answer:
12^2+15^2=18^2
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, thanks to the pythagorean theorem, we know a^2+b^2=c^2
So your answer is because 12^2+15^2=18^2
