Answer:
43.20
Step-by-step explanation:
First we need to find the sales tax
tax = price * tax rate
tax = 40 * 8%
= 40*.08
=3.2
We final cost is the price plus the sales tax
final cost = price + tax
= 40+3.2
= 43.20
Hypotenuse by Pythagoras theorem = 407.83.
Ok so what you will do is 3-18 then you will add 1 and make is to 400X1
21,985,233 to the millions place is 22,000,000
