Answer:
The tip was 15% of the meal.
Step-by-step explanation:
The amount of tip that miss Holman gave is 90 cent or $0.90
The total cost of the meal is $6.00
Let the tip is x% of the total cost of $6, so the amount of tip is,
But as it given as $0.90, so
Therefore, miss Holman gave a generous 15% tip to the waitress for serving the meal.
Answer:
As radius is perpendicular to tangent,
By pythagoras theorem :
x² = (x + 9)² - 15²
x² = x² + 18x + 81 - 225
18x = 207
x = 11.5
Answer:
x=7
Step-by-step explanation:
slope formula: (y2-y1)/(x2-x1)
(-8-9)/(x-(-3))=-17/10
-17/x+3=10
-17/7+3=10
-17/10=10
