Answer:
b) 516.2 cm³
Step-by-step explanation:
1) We can break the figure into two parts, a rectangular prism and a half cylinder.
2) The volume of the rectangular prism can be determined by multiplying 12 × 7 × 5, which is 420.
3) The equation for the volume of a cylinder is πr²h, but since this is half a cylinder, we will need to use the equation 1/2 × πr²h.
4) 1/2 × π × 3.5² × 5. The radius is 3.5, because the diameter is 7.
5) This should give us 30.625π.
6) Now we add 30.625π + 420, which is approximately 516.2.
Answer:
C
Step-by-step explanation:
Lines that are parallel AND have different y-intercepts will never intersect each other, therefore will have no solutions.
The only correct choice is C as the lines are parallel and have different y-intercepts which means they'll never intersect each other. All the other choices will have their lines intersect each other at some point.
Answer: 16 hours
Step-by-step explanation: Find the remaining number of pages David must write
24-16=8
Daniel must write 8 more pages
Find how long it takes Daniel to write one page
Since it takes Daniel an hour to write half a page, it takes him two hours to write a full page
Multiply how long one page takes by the remaining number of pages
2 x 8=16
It will take 16 more hours to write the total of 24 pages
