Answer:
1.66..is the decimal expansion of 5/3.
9514 1404 393
Answer:
B. (n²+n)/2
Step-by-step explanation:
You only need to try n=2 in the answer choices to determine which one gives a result of 3.
A. (2+1)/2 = 3/2 ≠ 3
B. (2² +2)/2 = 3 . . . . correct choice
C. (2² -2)/2 = 1 ≠ 3
D. (2 -1)/2 = 1/2 ≠ 3

<em>Additional comment</em>
The differences of the sequence 1, 3, 6, 10, ... are increasing, not constant. This means the rule will not be linear, but will be 2nd degree. (Second differences are constant.) This eliminates choices A and D immediately.
Step-by-step explanation:
we need much more information. you don't show us the diagram of the shape. for example.
it is impossible to know what you mean by a general angle between 3 points (?).
and we cannot even see the full screen shot.
Answer:
1200
Step-by-step explanation:
60 x
- = -
100 800
There are 2 ways to solve this.
1) 800 x 60= 48,000
Divide by 100= 480
x=480
2) Multiply 60 by 8.
Now there are another 2 ways to go.
1) 480 x
- = -
800 2000
<h2>
OR</h2>
2) 60 x
- = -
100 2000
<h3>
I recommend the second option for both. It is easier. The second option allows you to find and equal ratio, with less of the hassle. </h3>
To get 2000, 100 must be multiplied by 20. So.... multiply 60 by 20 to get a equal ratio.
Your answer is 1200. Meaning 1200 adults cooked dinner more than four nights per week.
I hope this helps you significantly
