Answer:
d
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= ![\frac{a(r^{n}-1) }{r-1}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%28r%5E%7Bn%7D-1%29%20%7D%7Br-1%7D)
where a is the first term and r the common ratio
Here a = 3 and r = 12 ÷ 3 = 4 , thus
= ![\frac{3(4^{8}-1) }{4-1}](https://tex.z-dn.net/?f=%5Cfrac%7B3%284%5E%7B8%7D-1%29%20%7D%7B4-1%7D)
=
= 65536 - 1 = 65535 → d
Answer: One half is the irreducible fraction resulting from dividing one by two (2) or the fraction ... One half often appears in mathematical equations, recipes, measurements
Step-by-step explanation: For example, if you wish to halve the fraction 5/7, write “* 2” beside the denominator “7.” There is no operation to perform to the numerator. Multiply the denominator by 2 to halve the fraction. Using the same example, 7 * 2 = 14. This means that half of 5/7 is 5/14.
30.(18) this is the answer I think but not sure
Answer:
The mean is all the numbers added together divided by the number of numbers. Greater the numbers the greater the mean. Since the goal of the game is to have as few centimeters away as possible the lowest number (107 or Robin) is winning
Step-by-step explanation:
Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.
