Answer:
C) 45°
Step-by-step explanation:
Do you know what an isosceles right triangle looks like?
Its legs are the same length and its acute angles are 45°. Compare that to the picture.
So, out of 60 balls, 48 passes and 12 did not that gives us a failure rate of 20%
20% of 2500 = 2000 hence 500 balls would not pass inspection,
10936.1 yards = 10 kilometers 1 kilometer = 1093.1 yards
Answer:
No diagram and no explanation what 9 is.
However, if it is an octagon with each side equal to 9 then
area = (# of sides * side^2) / (4 * tan (180 # of sides))
area = 8 * 9 * 9 / (4* tan (180 / 8)
area = 648 / 4 * 0.41421
area = 391.1059607446
answer is C
Step-by-step explanation:
Take out a common factor between 3x and kx. That means use the distributive law to get what you normally would start with.
x(k + 3) = 4
Now divide by k + 3
x = 4/(k + 3)
That's as much as you can do with this question.
