Area of square:

Side² = 9² = 81 ft²

Area of four triangles:

4 × 1/2 × base × height

2 × 9 × 10

180 ft²

Total Area:

180 + 81 = 261 ft²

Given the sequence in the table below, determine the sigma notation of the sum for term 4 through term 15. N an 1 4 2 −12 3 36 t
Rzqust [24]

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is                    \sum_{n=4}^{15} 5(-2)^{n-1}$$  

<h3>What is sequence ?</h3>

Sequence is collection of  numbers with some pattern .

Given sequence

a_{1}=5\\\\a_{2}=-10\\\\\\a_{3}=20

We can see that

\frac{a_1}{a_2}=\frac{-10}{5}=-2\\

and

\frac{a_2}{a_3}=\frac{20}{-10}=-2\\

Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2

Now n^{th}  term of this Geometric progression can be written as

T_{n}= 5\times(-2)^{n-1}

So summation of 15 terms can be written as

\sum_{n=4}^{15} T_{n}\\\\$\\$\sum_{n=4}^{15} 5(-2)^{n-1}$$

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is                    \sum_{n=4}^{15} 5(-2)^{n-1}$$

A cashier can ring up 12 items per minute. How long will it take the cashier to ring up 72 items? ​
Talja [164]

Answer:

So it will take 6 minutes to ring up 72 items.

Step-by-step explanation:

Well this seems pretty simple just have to reads the question and know what to find.

So what we know :

A cashier can ring up 12 items per minute

So :

1 minute = 12 Minutes

And we have to find :

How long for 72 items

So since we know he can do 12 in a minute and it is asking how many minutes it will take for 72 we can divide.

So :

72 / 12

=

6

So it will take 6 minutes to ring up 72 items.

I hope this helps!

If you have any questions or concerns feel free to message me or comment. :)

Please give me the correct answer!!!
Neko [114]

Answer:

Step-by-step explanation:

this one is tricky    so b/c the lines are at 90 degees we know that the arcs are similar so set up the parts of the arcs equal to 360 degrees

360 = 130  + 130  + x + x

see each part of the circle ?

then use your mad algebra skilz

100 = 2x

50 = x  

:)  nice.. when I do the math , it seems easy , huh :DDD
