Okay so a 24hr clock is very simple. We usually turn to "PM" when its 12:00 (day time).
In the 24hr clock we do not, we don't use PM or AM but its crucial to know when converting a standard clock time to military time (aka. 24hr).
9:30 PM in 24hr clock is 12:00 + 9:30 because 9:30 is past that first 12 hours.
So in 24hr clock time it is 21:30. You can also count backwards from midnight to figure it out, for example 12:00 AM (midnight), minus 9:30 is 2:30. Therefore 24:00-2:30=21:30.
Hopefully it helps, heart will help me alot too!
the formula is a_{1}+(n-1) d
so a_{1} would be the first number in the sequence, which would be 13 in problem 9.
13+(n-1)d
then you put in n, which is 10 (it represents which number in the sequence you're looking for, for example 16 is the second number in the sequence)
13+(10-1)d
then you find the difference between each number, represented by d which in this case is 3
13+(10-1)3
13+(9)3
13+27=
40
Answer:A
Step-by-step explanation:
Think about it as a process of elimination.
It can't be "B' for the simple fact that "increased by'' is a term that is often used for addition problems.
It can't be "C" because, as previously stated, sum is a term that is used in addition problems.
It can't be "D" because this is a unit that you are using.
Answer:
The tank can hold 18.84 cubic feet
Step-by-step explanation:
Given
Shape: Cylinder
-- Diameter
-- Height
Required
Determine the volume
First, calculate the radius (r)
![r = \frac{1}{2}D](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B2%7DD)
![r = \frac{1}{2}*2ft](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A2ft)
![r = 1ft](https://tex.z-dn.net/?f=r%20%3D%201ft)
The volume (V) of the tank is:
![V = \pi r^2h](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20r%5E2h)
Substitute values for r and h
![V = 3.14 *1^2*6](https://tex.z-dn.net/?f=V%20%3D%203.14%20%2A1%5E2%2A6)
![V = 3.14 *1*6](https://tex.z-dn.net/?f=V%20%3D%203.14%20%2A1%2A6)
![V = 18.84](https://tex.z-dn.net/?f=V%20%3D%2018.84)
<em>Hence, the tank can hold 18.84 cubic feet</em>
This polynomial has only 3 terms, so it is a trinomial. <em>Hope it helps!</em>
