Answer:

Part A: Let the September price be x, then

1.2x = 1.5

x = 1.5/1.2 = 1.25

Therefore, September price is $1.25

Part B: In September, they earned 0.4 * 1.25 * 900 = $450

In October, they earned 0.4 * 1.5 * 700 = $420

Therefore, they earned more money in September.

Find the area of the shaded region. Use 3.14 for pi. Round to the nearest tenth.<br> r = 15<br> 110
Svetradugi [14.3K]

Answer:

110/360=11/36 (I will get back to this)

The area of the circle would be 225 pi using the formula pi r^2. So you multiply 225pi by 11/36 to find the area.  This rounds to 215.98

What is the percent of change from 50 to 23?
Taya2010 [7]

Answer:

50 is the old value and 23 is the new value. In this case we have a negative change (decrease) of -54 percent because the new value is smaller than the old value. Using this tool you can find the percent decrease for any value.

PLZ HELP! 20 POINTS!
agasfer [191]

Answer:

a) The error is that, the initial value is n=1 NOT n=3

b) The sum is a_n=a_{n+1}+5=192

c)The explicit formula is  a_n=5n+3

The recursive formula is a_n=a_{n+1}+5,

Step-by-step explanation:

The given arithmetic series is  8 + 13 + ... + 43.

The first term is a_1=8, the  common difference is d=13-8=5

The nth term is given by:

a_n=a_1+d(n-1)

We substitute the values to get:

a_n=8+5(n-1)\\a_n=8+5n-5\\\\a_n=3+5n

To find how many terms are in the sequence we solve the equation:

3+5n=43\\\implies 5n=43-3\\5n=40\\n=8

The summation notation is  \sum_{n=1}^8(3+5n)

The error the student made is in the initial value.

It should be n=1 NOT n=3

b) The sum of the arithmetic series is calculated using:

S_n=\frac{n}{2}(a+l)

We substitute o get:

S_8=\frac{8}{2}(5+43)

S_8=4(48)

S_8=192

c) The explicit formula we already calculated in a), which is a_n=3+5n

The recursive formula is given as:

a_n=a_{n+1}+d

We substitute d=5 to get:

a_n=a_{n+1}+5
