Atennis racket normally costs $65 . the tennis racket is on sale for 20% off . what is the sale price of the tennis racket

$52

Step-by-step explanation: To find the sale price of the tennis racket, we first need to find the discount by multiplying the original price by rate of discount. In this problem, the original price of the tennis racket is $65 and the rate of discount is 20% or .20. Now, we can simply multiply.

65 x .20 = 13

The discount is $13.00

Next, let's find the sale price. The formula for finding the sale price is below.

Original price - discount = sale price

In this problem, the original price is $65 and the discount is $13.00 so we can subtract 65 - 13 and we get $52.

Therefore, the sale price is $52.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
