Answer:
11π/4 (radians) or 495° (degrees)
Step-by-step explanation:
Convert 165° to radians:
165 * π/180 = 165π/180 = <em>11π/12</em>
s = r/Ф
arc length = 3(11π/12) = 33π/12 = 11π/4
Convert back to degrees if asked to:
11π/4 * 180/π = 495° (Note that this is 165° * 3, see the pattern?)
Answer:
Range
The set of output values is called the range of the function.
Answer:
B i think
Step-by-step explanation:
Answer:
y = -2/3 x - 1
Step-by-step explanation:
y = mx + b
y = -2/3 x + b
-5 = -2/3 × 6 + b
-5 = -4 + b
b = -1
y = -2/3 x - 1
Rate for Sally is 1 room per 8hrs
rate for Steve is 1 room per 7hrs
combined rate:
1/8 + 1/7 = 1/T
7/56 + 8/56 = 1/T
15/56 = 1/T
56/15 = T
3 11/15 = 3 hrs 44 min
