Answer:
$90.75
Step-by-step explanation:
First we convert kilograms to pounds.
1 kg = 2.2 lb
15 kg = 15 * 2.2 lb = 33 lb
Cost of shipping: $2.75/lb
Cost of shipping 33 lb: 33 lb * 2.75/lb = $90.75
Answer: $90.75
Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:

a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:

Then, use the squares in the equation:

Then, subtract 100 from both sides to isolate b:

Finally, square root both sides to get your answer:

Then round to the nearest tenth which gives you 17.3.
