Answer:
15°
Step-by-step explanation:
x = angle
Complement and x sum to 90° so the complement angle = 90 - x
x = 4 ( 90 -x) - 285
x = 360 - 4x - 285
5x = 75
x = 15°
Answer:
(- 3.5, 0.5 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( , )
Here (x₁, y₁ ) = (- 3, - 1) and (x₂, y₂ ) = (- 4, 2) , then
midpoint = ( , ) = ( , ) = (- 3.5, 0.5 )
Answer:
estimate: around 60mph
actual: 65 mph
Step-by-step explanation:
estimate: rounded 55 to 60 so 1 minute=1 mile then multiply both by 60 (bc there is 60 minutes in an hour) the get 1 hour=60 miles, so the estimate is 60mph
actual: 55 seconds=1 mile so divide 60 by 55 seconds to get about 65 miles per hour
Answer:
1:52 PM
