Answer:
Wat is the question?
Step-by-step explanation:
The answer to your question is A, 11/24
Answer:
They drove 150 miles on the third day
They drove 50 miles per hour so if you multiply that by 3 (since they drove 3 hours on the third day) you would get 150 miles.
Answer:
k + 1
v(s) = -------------
S
Step-by-step explanation:
Solve the equation S=k/v(s)+1/v(s) for v(s).
To do this, combine the two terms on the right side, which is easily possible becuse they have the same denominator: v(s):
k + 1
S = ------------
v(s)
Now interchange S and v(s), obtaining:
k + 1
v(s) = -------------
S
Answer:
A ≈ 9.0 ft²
Step-by-step explanation:
70° = 7π/18 radians
Area of the arc section
A = ½(7π/18)8² = 12⁴/₉π ft² = 39.09537 ft²
As the triangle is isosceles, the other two angles are (180 - 70) / 2 = 55°
law of sines 8 / sin55 = L / sin 70 L = 9.17722
so the triangle height = √(8² - (9.17722/2)²) = 6.55321
Area of triangle ½(6.55321)(9.17722) = 30.07016
Area = 39.09537 - 30.07016 = 9.025211 ≈ 9.0 ft²
