To calculate final cost you need to add tax and tip. Because you tip on the food bill without tax, you just add these two.
72 * 0.2 = 14.4 -> tip
72 * 0.06 = 4.32 -> tax
72 + 14.4 + 4.32 = 90.72
So the total cost was $90.72
You can find that faster:
72 * 1.26 = 90.72

Step-by-step explanation:
A tennis ball is a sphere
Volume of a sphere ===> v= \frac{4}{3} \pi r^3
Plug in the given info
v= \frac{4}{3} (3.14) (6.7)^3
Do the math to get a final answer of:
v= \frac{4}{3} (3.14) (6.7)^3=1259.19cm^3

Answer:
Six cases are enough to construct more than one isosceles triangle
Step-by-step explanation:
An Isosceles triangle is a triangle in which at least two of it's sides are congruent.
If two of the three sides of a triangle are congruent, but the third side is of a different length, the triangle is isosceles.
If all three sides of the triangle are congruent, even though this is an equilateral triangle, it satisfies the condition of an isosceles, and it is ok to still it isosceles.
Julius might decide to split information for a better explanation, it doesn't matter the number of cases he has, but six cases should be enough to draw an isosceles triangle.
