Answer:
c) 1,381.5.
Step-by-step explanation:
First term = 3.1 *1 - 2 = 1.1
2nd term = 3.1*2 - 2 = 4.2
3rd term = 3.1*3 - 2 = 7.3
so the common difference d = 3.1.
S30 = (30/2) [ 2* 1.1 + (30-1) * 3.1)]
= 1,381.5.

Answer:
16 students can sit around a cluster of 7 square table.
Step-by-step explanation:
Consider the provided information.
We need to find how many students can sit around a cluster of 7 square table.
The tables in a classroom have square tops.
Four students can comfortably sit at each table with ample working space.
If we put the tables together in cluster it will look as shown in figure.
From the pattern we can observe that:
Number of square table in each cluster Total number of students
1 4
2 6
3 8
4 10
5 12
6 14
7 16
Hence, 16 students can sit around a cluster of 7 square table.
Ariana cannot ship all the bags in one box.
Ariana will be sending 8 bags which will weigh a total of:
= 22 ounces x 8
= 176 ounces
You need to convert this to pounds to see if it will fit in the box:
<em>1 pound = 16 ounces </em>
176 ounces in pounds is therefore:
= 176 / 16
= 11 pounds
The box can only take 10 pounds and 5 ounces which is less than the 11 pounds the bags weigh.
Ariana cannot ship all the bags in one box.
