Answer:

$15.21

Step-by-step explanation:

17% of $13=0.17*13=2.21

13 (the price of the actual lunch) +2.21= 15.21

Alternatively, you can just do the operation:

13*(1+0.17)=15.21

This is because 1*13=the price of the actual lunch and 0.17*13=the price of the tip

A square ceiling has a diagonal of 23 ft. Shelton wants to put molding around the perimeter of the ceiling. The molding is sold
Hatshy [7]

Answer:

Minimum 66 feet of molding that he needs.

Step-by-step explanation:

Given that a square ceiling has a diagonal of 23 ft.

If the sides of the square ceiling are 'a' feet, then applying Pythagoras Theorem we can write, a² + a² = 23²

⇒ 2a² = 23²

⇒ a = 16.2634 feet (Approximate)

Now, the perimeter of the square ceiling will be 4a = 65.05 feet.

If the cost of molding along the perimeter of the ceiling is in per foot, then a minimum of 66 feet of molding that he needs. (Answer)
