Answer:
The answer is 24.
Step-by-step explanation:
I know this because you do PEMDAS, multiplication inside the parentheses, which gets you (35+7-18), an addition which gets you (42-18), and subtraction, which ultimately will get you 24 as the final answer.
1 Yes 2. Yes
Step-by-step explanation:
they are similar because in problem one each side is related by a factor of 3
in problem 2 each side is related by a factor of 2.
Answer:
3.036, 3.36, 3.3661 , 3.5
Step-by-step explanation:
Look at the first 2 numbers
3.3661, 3.5, 3.36, 3.036
We can order them as 3.0 , 3.3 , 3.3 . 3.5
So 3.036 is first one
Now we have 2 of the 3.3's
One is 3.3661 and the other one is 3.3600
Because if you add a number to the end it will always be a zero and it wont change the answer
So 3.36 is second and 3.3661 is third one
3.5 is bigger than 3.3
So 3.5 is last
Answer:
12.56 (13 if rounded)
Step-by-step explanation:
A=pi x r squared
A=2 squared multiplied by pi
A=4 times pi
plug into calculator should be about 12.56
Answer:
341
Step-by-step explanation:
The number of people who know the art of quilting in each successive generation is
1, 4, 16, …
These numbers represent a geometric sequence where each term has the form
aₙ = a₁rⁿ⁻¹
In your sequence, a₁ = 1 and r = 4.
Then, the formula for your sequence is
aₙ = 4ⁿ⁻¹
Sum over five generations
The formula for the sum of the first n terms of a geometric series is
Sum = a₁[(1 - rⁿ)/(1 - r)]
Sum = 1[(1 - 4⁵)/(1 - 4)
= (1 - 1024)/(-3)
= -1023/-3
= 341
If the process continues for five generations, 341 people will know the art of quilting.
