Mark spent 5/12 of an hour on his math homework and 6/12 of and hour on english homework altogether, what fraction of an hour did mark spend on his math and english homework

Spends no more than 2 hours on her math and science homework. If math always takes about twice as long as science, what is the maximum time spent on science

Step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
