I hope this step by step explanation helps.
If they purchase a bike for 60, and sell it for 120, they make a profit of 60. Theywould need to sell 40 bikes to break even. 120 - 60(buying cost) = 60. 2400 / 60 = 40
Answer:
The slope is 6
Step-by-step explanation:
Rise/run
The rise is 6 and the run 1
Then simplfy 6/1 to get 6
Answer:
m<1 = 45°
m<2 = 76°
m<3 = 80°
Step-by-step explanation:
<u>Points to remember</u>
1). Vertically opposite angles are equal
2). Sum of angles of a triangles is 180°
<u>To find the measures of given angles</u>
From the figure we get,
m<1 = 45° [Vertically opposite angles]
By using angle sum property <2 + 59 + 45 = 180
m<2 = 180 - 104
m<2 = 76°
Also m<1 + m<3 + 55 = 180
m<3 = 180 - (m<1 + 55)
= 180 - (45 + 55)
= 180 - 100
m<3 = 80°
