We add all these mixed numbers together:
1 1/2 + 2 3/4 + 2 1/3
It will be easier to convert the mixed numbers into improper fractions:
3/2 + 11/4 + 7/3
Now we have to find the common denominator which is 12:
18/12 + 33/12 + 28/12 = 79/12 = 6 7/12
The answer is 6 7/12 hours.
Answer:
Step-by-step explanation:
The attached diagram shows the triangle ABC formed by the ladder with the wall of the house.
Triangle ABC is a right angle triangle. It has a 90 degree angle. The length of the ladder forms the hypotenuse(AC)of the triangle. This length can be determined by applying Pythagoras theorem
Hypotenuse^2 = opposite ^2 + adjacent^2
AC^2 = 22^2 + 5^2
AC^2 = 484 + 25 = 509
AC = √509
AC = 22.56
The slope of the ladder is
(change in y)/(change in x)
Slope = 22/5 = 4.4
The reference angle is
pi/3.
At 180 it would be 9pi/3 so going past that is 10pi/3.

387.50(1-49%)=197.625
final answer: $197.63
Answer:
its 210
Step-by-step explanation:
area of rect is 20×12=240
tri angle area=1/2×5×12=30
so 240-30=210
