I believe this is pathgorean theorem, which I did at the beginning of alegbra last year. It is basically finding the missing side of a triangle. (Trust me some of the easiest stuff you do all year) Below are my notes from last year. I hope it helps! Good Luck!!!

Step-by-step explanation:

Given two sides

If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:

a² + b² = c²

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:

a = √(c² - b²)

if leg b is unknown, then

b = √(c² - a²)

for hypotenuse c missing, the formula is

c = √(a² + b²)

Bob and Maria each purchase steak from the butcher. Maria selects a cut that costs $19.98 per pound. Bob’s selection costs $13.9

Sidana [21]

Answer:

Bob is paying more for the actual steak

Step-by-step explanation:

we know that

Maria selects a cut that costs $19.98 per pound (Maria's steak is all meat)

Bob’s selection costs $13.98 per pound (Bob’s cut of beef is 1⁄3 bone and fat)

Bob's cut is 2/3 all meat

Find the unit rate of Bob's cut for all meat

$\frac{13.98}{(2/3)} \frac{\$}{pounds} =20.97\frac{\$}{pounds}$

therefore

$\$20.97> \$19.98$

Bob is paying more for the actual steak
