The total cost of the meal was $28.50 ($25 for meal + $3.50 for tip)
The tip was 14% of the total cost of the meal ($25 x .14(14%))=%3.50
Hope this helped you! :D
Answer:
y= -2/5 x -4
Step-by-step explanation:
So the equation is y=mx+b. Where m=slope and b=y-intercept. To find b, you would see at what point does the line cross the y axis. That would be at -4 so, -4 would be the b or y-intercept. To find m, you would take two points on the line and use this equation:
m=(y2 - y1 )/(x2 - x1)
If you were using the points, (-10,0) and (0, -4) the equation would be:
m=(-4-0) / (0+10)
So, m= -2/5
The equation of the line would end up being:
y= -2/5 x -4
Answer:
1,017.36 ft²
Step-by-step explanation:
surface area of the cone = π×r×s
= 3.14 × 13.5 × 24
= 3.14 × 324
= 1,017.36 ft²
