Multiply any decimal by 100 to convert it to a percentage
Ex: .45 x 100 = 45%
180 miles because 45 minutes is three quarters of an hour so you multiply 3.75hrs times 48mi which equals 180 miles.
Great question! A midpoint is exactly what it sounds like; the point in the middle of two objects (in this case it's the middle of these two coordinates). Another way to think of the middle of something in math is by using the average. To find the midpoint of two points, we just find the average of the x-values and the average of the y-values:
((x1 + x2)/2 , (y1 + y2)/2)
((5 + -13) / 2 , (-4 + 12) / 2)
( -8 / 2 , 8 / 2)
(-4 , 4)
Answer:
Cosine Formula :
AC² = AB² + BC² - 2(AB)(BC)cosB
AC² = (40)² + (60)² - 2(40)(60)cos(115°)
AC² = 1600 + 3600 - (4800×(-0.42))
AC² = 5200 + 2016
AC² = 7216
AC = √(7216)
AC = 84.95 km
Hence, the distance of the straight line AC is <u>84.95 km</u>
- <u>84.95km</u> is the right answer.
