Answer:36hrs
Step-by-step explanation:
300*36/5 that you have the time of eating in mins
divide it by 60 then you have hours
1 mile is 6 times
5/6 of a mile... x times
<span>x= 5/6 x 6 = 30/6= 5 times</span>

Answer:
Please check explanations
Step-by-step explanation:
Using the difference of two squares, the lowest common multiple becomes;
1-sin^2 a
Thus, we have that;
cos a (1-sin a) + cos a (1 + sin a) /1 - sin^2 a
1 - sin^2 a = cos^2 a
That means;
{cos a - cos a sin a + cos a + cos a sin a}/ cos^2 a
= 2cos a / cos^2 a
= 2/cos a
but 1/cos a = sec a
Thus;
2/ cos a = 2 sec a
