Answer:
m∠I = 58.4°
Step-by-step explanation:
cos = adjacent side/hypotenuse
It is always helpful to have a picture. In your case KI is adjacent to ∠I and IJ is the hypotenuse.
So cos I = KI/IJ = 4.5/8.6
arccos (4.5/8.6) = m∠I
m∠I = 58.4°
It is necessary for you to memorize the definitions of the trig functions in order to do these types of problems. OK?
Answer:
4/13 hours
Step-by-step explanation:
Total pounds of lasagna = 4 1/3 pounds
Total time taken to cook = 1 1/3 hours
How many hours per pound did it take to cook the lasagna?
Hours per pound of lasagna = Total time taken to cook / Total pounds of lasagna
= 1 1/3 hours ÷ 4 1/3 pounds
= 4/3 ÷ 13/3
= 4/3 × 3/13
= 4/13 hours
It will take 4/13 hours to cook each pound of the lasagna
1 gallon = 4 quarts so 3 gallons = 12 quarts
so 30 quarts is larger.
