The sequence is a geometric sequence with a common ratio of 2. since the common ratio is greater than 1, the sequence diverges.
The shelf can hold: 15 x 5 = 75 books
Two thirds of the shelf: 75(2/3)= 50 books
15 liters of water would be needed. 9/24=.375. he’s using .375 of a liter for each pot. .375x40=15. he’d need 15 total.
X=20
AD= 23
DC= 23
AC= 46
The median means both sides of the line AC are equal.
Therefore: x+ 3 = 2x-17
and we can solve this for x
Subtract x from both sides
x-x = 2x-x -17
3 = x -17
Add 17 to both sides
3 +17 = x -17+17
20 = x
The length of AD is x + 3, replace x with 20:
20 + 3 = 23
The length of DC is the same as AD (because they’re separated by the median) so DC= 46
AC is the length of AD + DC,
23+23= 46.
AC= 46
The answer is A because 2 multiplied by 9 is 18
