Set up a proportion:
First convert 75 inches to feet.
75 in = 6.25 ft
1/6.25 = x/50
Multiply 50 to both sides:
50 * 1/6.25 = x
50/6.25 = x
x = 8
So the tire will rotate 8 times after Frank rides 50 feet.
By simplifying both sides of the equation then isolating the variable
Answer:
90° + (γ/2)
Step-by-step explanation:
The angles in ΔADB have a sum of 180°, so ...
(A/2) +(B/2) + ∠ADB = 180°
and so do the angles of ΔABC:
A + B + γ = 180°
Dividing this second equation by 2 gives an expression for (A/2) +(B/2) that we can substitute into the first equation:
A/2 +B/2 +γ/2 = 90°
A/2 +B/2 = 90° -γ/2
Putting this in the first equation, we have ...
(90° -γ/2) + ∠ADB = 180°
∠ADB = 90° +γ/2 . . . . . . . . . . add (γ/2 -90°)
Answer: The answer is A 1/16
Answer:
Yes
Step-by-step explanation:
The negative sign was simply moved to either the numerator or denominator. Either way the number is still a negative one half.
