It wouldn't affect the mean or the median.
To change a degree measure to a radian measure, we multiply by (π/180). So 360° becomes 2π radians, and 240° becomes 4π/3.
Teds minimum grade he needs on his third test is 65
85 + 60 + 65 = 210
210 divide by three (as there are three tests) = 70
B is the answer
Choice-a). two equal angles.
-- Choice-b).
-- Choice-c). If they were each 60°, then the total
for the triangle would be (130+60+60) = 250° .
-- Choice-d). two equal angles.
Answer:
x = 11.5 hours
Step-by-step explanation:
Set up a proportion:
= 
661.25/460 = 1.4375
Multiply 8 by 1.4375 to find x:
8(1.4375) = 11.5
x = 11.5 hours
