Answer:
A. 23.1
B. 0.3
Step-by-step explanation:
When rounding to one decimal place, look at the next number, (in this case, in the hundredths column) if the number is 5 or above, round up and if it’s four or below, round down
Sin 45 = sin 45
sin 135 = sin (180 - 45) = sin 45
sin(225) = -sin(180 + 45) = -sin 45
sin 315 = -sin(360 - 45) = -sin 45
cos 224.5 = -cos(180 + 44.5) = -cos 44.5
cos 658 = cos(658 - 360) = cos 298 = cos(360 - 62) = cos 62
cos 145.7 = -cos (180 - 34.3) = -cos 34.3
sin (-201) = sin (360 - 201) = sin(159) = sin (180 - 159) = sin 21
Answer:
Because you cant have -6 yards thats not a thing. Now if it was just 6yd that would be an okay answer because you could measure that.
Step-by-step explanation:
139 mi 1 km 139 km
--------- * ---------- = -------------- = 11.2 km
20 0.62 mi 12.4
