50ft! you find the hypotenuse of the triangle so i simplified it down and got the right side angles of 30 ft and 40ft then you do a^2 + b^2 = c^2
First lets get the total weight that Hailey bought, that is working with fractions:
1 3/7 = 7/7 + 3/7
= 10/7 = 1.43
so we use a rule of three to solve this:
1.43 kg ------> $13
1 kg --------> x
x = (1)(13)/(1.43)
x = 9.09
therefore a 1kg of sliced salami costs $9.09

Answer:
x =20
Step-by-step explanation:
Factorize 81
