What is S7 for 6 – 24 + 96 – 384 + ... ?
Dmitry [639]
6 - 34 + 96 - 384 +... 
a 1 = 6 , a 2 = a 1 * ( - 4 ) ,  a 3 = a 2 * ( - 4 ), a 4 = a 3 * ( - 4)...
a 5 = - 384 * ( - 4 ) = 1,536
a 6 = 1536 * ( - 4 ) = - 6,144
a 7 = - 6,144 * ( - 4 ) = 24,576 
This is a sum of a geometric sequence:
S 7 = 6 - 24 + 96 - 384 + 1,536 - 6,144 + 24,576 = 19,662
Another way to solve this:
S 7 = a 1 * ( r^n - 1) / ( r - 1 ) = 6 * (( - 4) ^7 - 1 )/ (- 4 - 1)=
= 6 * (-16,385) / (-5 ) = 19,662

A recycling plant processes an average of 1/3 ton of glass each minute. At approximately what rate does the recycling plant proc
ludmilkaskok [199]

The recycling plant processes 480 tons of glass per day.

Step-by-step explanation:

Quantity of glass recycled each minute = \frac{1}{3}\ tons

We know that;

1 hour = 60 minutes

Therefore;

Quantity of glass recycled in one hour = \frac{1}{3}*60=20\ tons

1 day = 24 hours

Quantity of glass recycled in 24 hours = 24*20 = 480 tons

The recycling plant processes 480 tons of glass per day.

A company buys pens at the rate of $5.50 per box for the first 10 boxes, $4.50 per box for the next 10 boxes, and $3.50 per box
marusya05 [52]

So it is really easy to solve firstly we can see how much does the first 10 boxes make which makes around 55$ obviously. Secondly 45$ for the next 10 boxes.

So for now we can simply calculate that we have spent around 100$ which means 20 boxes. The remaining money left is 77$ so we can buy 77/3.5 = 22 only 22 boxes with that money. Hence a total of 42 boxes.
