The chef at LaBerge started the week with 50 pounds of cheese and used 15 4/5 pounds. How much cheese
larisa [96]

Answer: 34.2 pounds

Step-by-step explanation:

First, convert 15 4/5 into an improper fraction. You should get 79/5. Then, convert 50 into a fraction that has a denominator of 5. Right now, 50= 50/1 so just multiply the top and bottom by 5 to make it 250/5. Then, subtract 79/5 from 250/5. You should get 171/5. Lastly, simplify. You should get 34.2 pounds as your final answer. Hope this helps!

The diagonal measure of a rectangular T.V screen is 42 inches. The width of the screen is 36.6 inches
olga55 [171]
A^2 + b^2 = c^2
The diagonal is the hypotenuse (c).
36.6^2 + b^2 = 42^2
1339.56 + b^2 = 1764
Subtract 1339.56 from both sides.
b^2 = 425.44
Square root both sides.
b = 20.6 inches
