Answer:
The sum of the arithmetic series is 2717.
Step-by-step explanation:
The sum of an arithmetic sequence is given by:

Where <em>k</em> is the number of terms, <em>a</em> is the initial term, and <em>x</em>_<em>k</em> is the last term.
There are 22 terms, the first term is 7, and the last term is 240. Hence, the sum is:

In conclusion, the sum of the arithmetic series is 2717.
Answer:
1/30 or .00119 (Same answer, just in decimal form)
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
A midpoint divides the segment into two equal parts. Each is half the length of the whole.
XY = (1/2)XZ
5x+4 = (1/2)(8x +16)
5x +4 = 4x +8
x = 4 . . . . . . . . . subtract 4x+4 from both sides
_____
<em>Check</em>
5x+4 = 5(4)+4 = 24
8x+16 = 8(4) +16 = 48
So, XY is half of XZ.
Answer:
Step-by-step explanation:
V = (4/3)πr3 so put it on a calculator (4/3)3.14 (or Pi) times radius which is r to the 3rd power so your answer would be 33.51 but make sure
Answer:

Step-by-step explanation:
The long division for 3/8 results in getting 0.375, so 45 3/8 is 45.375.
From here, the only thing you can really do is divide it by 10 to get
4.5375 and since you can't divide further, the answer would be
4.5375 * 10^1
