855 is the lcm (19 x 45)
First push the ' 2nd' key Then the cos key becomes acos which is arc cos or inverse cos (all the same thing)
There are 30 days in the month of April
7 days it rained 7 out of 30 7/30 x 100% = 23.33%
Don't know what you are looking for but 2/sqrt(3 = 1.1547005383792515
or 2 sqrt3 / 3
cos^-1(.25) =75.52degrees Cosine is POSITIVE in QUADRANTS I and IV, so 360-75.52=284.48 degrees is the other answer
Pretty straightforward.....just subtract 14 from both sides of the equation
p+14-14 <20-14
p<6 Voila!
Hello Guest..... Thanx for posting on the forum.
Did you try your answer in the equation to see if it 'works' ?
what do you think (3x+6)^2 equals? Might want to try it !
Happy Birthday , Chris-Guru...... Just how old IS ∞ +1 ??
Have a good one!
49 Girls 10 by car 20 biked then 19 walked total = 49
