Woodhill Elementary School is planning a field trip for grades 3, 4, and 5. There is a total of 464 students. There are only 45 seats per bus. How
many buses will be needed for the field trip?

11 buses

Step-by-step explanation:

If you divide 464 by 45, you will get 10.3. You need to round this number up to 11, since you would need another bus to carry the 0.3 of students left over.

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 !

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
