t + 4/3 t = 84
7/3 t = 84
(3/7) 7/3 t = 84 (3/7)
t = 36
Just multiply them together to find out:
11/24 x 8 = 11/3 = 3 2/3
3cosx = - sinx
cosx = -1/3sinx
cosx/sinx = -1/3
sinx/cosx = -3
tanx = -3
x =arctan(-3) = -71.565 degrees = 288.435 degrees and 108.43 degrees
3e0 is 3 if you enter '3' then '=' that is what you will get....make sure you actually hit the sqrt key
Approximated to be 365.25 days/year
Subtract 5 from both sides of the equation to get:
2/3x = -12 then multiply both sides by 3/2 to get
x = -12 (3/2) = -18
20 people PER 5 x 5 = 25 sq ft
500 x 500 = 250,000 sq ft 250,000/25 sets of 20 people = 10,000 sets of 20 people
10,000sets x 20 people = 200,000 people
80 x 80 = 6400 sq ft 6400 sq ft / (4.5 sq ft/person) = only 1422.2 people will fit comfortably
20 x 20 = 400 sq ft
100 x 100 = 10,000 sq ft
10,000/400 = 25 times bigger of a room 25 times 50 = 1250 students in the larger room
10 x 80 = 800 first ten minutes
80 x .75 =60 each minute x 5 300
60 x .50 = 30 each minute x5 150
