Is the volume of the pyramid greater than the volume of prism?
No, so throw out the third one
so by inspection it must be the remaining one
or mathematically
vol pyramid = (1/3)(base)(height)
vol prism = (base)(height)
vol pyramid / vol prism
(1/3)(base)(height) / (base)(height) = 1/3

Find the sum of the first 6 terms of the following series, to the nearest integer.
180, 30, 5, ...
Answers
Answer:
Step-by-step explanation:
First solve for the common ratio:
[tex]\frac{30}{180} = \frac{1}{6} 6 \\ \\\frac{5}{30} = \frac{1}{6}[/tex]
Use the geometric summation equation to solve for sum:
[tex]a(\frac{(1-r^{n} )}{(1-r)})\\180(\frac{(1-\frac{1}{6} ^{6}) }{(1-\frac{1}{6} )}) = \frac{46655}{216} = 216[/tex]
The sum of the first 6 terms of the following series is 540.
What is the geometric series?A geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.
The sum of the terms of the geometric sequnece is given by;
[tex]\rm S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
The common ratio of the sequence is;
[tex]\rm \dfrac{a_2}{a_1}=\dfrac{30}{180}=\dfrac{1}{6}\\\\ \dfrac{a_2}{a_1}=\dfrac{5}{30}=\dfrac{1}{6}\\\\[/tex]
The sum of the first 6 terms of the following series is;
[tex]\rm S_n=\dfrac{a(1-r^n)}{1-r}\\\\\rm S_6=\dfrac{180(1-1/6^6)}{1-1/6}\\\\ S_6=\dfrac{180\times 0.99}{5/6}\\\\S_6=\dfrac{180\times 0.99}{0.33}\\\\S_6=\dfrac{178.2}{0.33}\\\\S_6=540\\[/tex]
Hence, the sum of the first 6 terms of the following series is 540.

Answers
Answer: Both of them
Step-by-step explanation:
There are 15 books in the series.
Terrance has 12 of them and Keymar has 4/5 of them.
The number that Keymar has is:
= 4/5 * 15
= 60/5
= 12 books
They therefore both have the same number of books from the collection.

Find the mean absolute deviation (MAD) of the following data set. Round your answer to two decimal places.
3, 10, 6, 9, 7, 4
Answers
Answer:The mean absolute deviation (MAD) of the data set=2.17
Step-by-step explanation:
The mean absolute deviation (MAD) is also called the Mean deviation which tells us the variation and average distance of the mean and each data value in a data set.
Given the data set
3, 10, 6, 9, 7, 4
First find the mean
Mean =Sum of data set / Number of data set
=3+10+ 6 +9 + 7+ 4/ 6 =39/6 = 6.5
Next step is to subtract each data set from the mean and ignoring any negative sign accompanied to find the distance from the mean
Value distance from mean
3, 6.5 -3 3.5
10 6.5 -10 3.5
6, 6.5-6 0.5
9, 6.5 -9 2.5
7, 6.5 -7 0.5
4 6.5 -4 2. 5
Last step is to find the mean of the distances which is
Mean Deviation = (3.5+ 3.5+ 0.5+ 2.5+0.5+ 2.5) / 6
=13/6

Tickets for a carnival for a family of 4 costs $28. The ticket includes 1 food item and 3 games.
Select all true statements below based on this information.
A The cost for 2 tickets is $20. The cost for 2 tickets is $20.
B The cost is $7 per ticketThe cost is $7 per ticket
C For $42 you could get 6 tickets. For $42 you could get 6 tickets.
D 12 tickets would cost you $60
Answers
Answer:
B
Step-by-step explanation:
28/4=7 therefore, each ticket is $7.
Answer:
B, C
Step-by-step explanation:
A is wrong due to the fact that if you divide $28 into 4 (family of 4), the cost is $7 per ticket. If you add 2 tickets together, or multiply $7 by 2, you get $14.
B is right due to the fact that each ticket is $7 if you divide $28 by 4.
C is right due to the fact that if you have 6 tickets worth $7 each, it would mean that the total cost of 6 tickets would be $42. (6*7 = 42)
D is wrong due to the fact that if you multiply 7 (the cost of each ticket) by 12, it gets you 84, not 60.

Two trains, Train A and B, weigh a total of 251 tons. Train A is heavier than train B. The difference of their weights is 181. What are the weights of each train?
Answers
Answer: A = 216; B = 35
Step-by-step explanation:
Based on the information given in the question, we can then make it into a mathematical equation. This will be:
A + B = 251 ....... i
A - B = 181 ....... ii
From equation i,
A = 251 - B
Put the value of A into equation ii
A - B = 181
(251 - B) - B = 181
251 - B - B = 181
251 - 2B = 181
2B = 251 - 181
2B = 70
B = 70/2
B = 35
Since A = 251 - B
A = 251 - 35
A = 216
