Answer:
measure of???
Step-by-step explanation:
Step-by-step explanation:
Use arc length:
s = rθ
where r is the radius and θ is the angle in radians.
a) First, convert the angle to radians (1 degree = 60 minutes).
77 ⁵⁰/₆₀° × (π radian / 180°) = 1.358 radians
s = rθ
s = (9.67 in) (1.358 rad)
s = 13.1 in
b) s = rθ
4 in = (9.67 in) θ
θ = 0.414 radians
θ = 23.7°
θ = 23° 42'

Answer:
57 + 3x
Step-by-step explanation:
“More than” is called “+”.
“Times” is called “×”.
Greg's score will be represented as “x”.
Note: “3x” also means “3 × x”.
a) +17 -9 = +8 . . . a profit of $8
b) +9 -5 = +4 . . . a rise of 4 cm
c) -6 -4 = -10 . . . a drop of 10 °C
_____
Each integer has a sign chosen with respect to some reference direction. We usually choose a rise or increase or profit to be the positive direction, so a drop or decrease or loss is then represented by a negative number.
