The probability it will take 20 minutes or more is about 6.3%.
using the law of cosines:
a^2 = b^2 + c^2 - 2*b*c*cos(A)
a = 90, b = 55, c = 50
90^2 = 55^2 + 50^2 - 2*55*50*cos(A)
8100 = 3025 + 2500 - 5500 * cos(A)
5500 * cos(A) = 3025 + 2500 - 8100
5500 * cos(A) = -2575
cos(A) = -103/220
A = arccos(-103/220)
A = 117.9 degrees
Answer:
2/3
Step-by-step explanation:
parallel lines have the same slope
given that a line has a slope of 2/3
a line that is parallel to this line would also have a slope of 2/3
The first one because .33 is not repeating .33 33 33 33 33 and .3 is .3 3 3 3 3 3
So that's why it's the first one.
Hope this helps!
I don't know about square inches, I can't convert 128 inches to square inches is there anyway Google or something can help you?
