Answer:
see below
Step-by-step explanation:
The Pythagorean theorem is for right triangles. It uses the two legs and the hypotenuse
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
Part A
We have x = 4 and y = 3 paired up together.
This says that 4 pounds of potatoes cost $3
The price per pound (aka unit price) is y/x = 3/4 = 0.75 dollars = 75 cents.
Answer: 75 cents per pound
========================================
Part B
The ordered pair (8,6) means x = 8 and y = 6 pair up together.
So in this case, 8 pounds of potatoes cost $6.
notice how y/x = 6/8 = 3/4 = 0.75 dollars = 75 cents here as well. So we get the same unit cost.
The answer is 25. you can find the answer by setting up a proportion.
<span>partial products for 51 × 36
50 x 30 = 1500
50 x 6 = 300
1 x 30 = 30
1 x 6 = 6
