aleksley [76]

Answer:

  630

Step-by-step explanation:

The sum of an arithmetic sequence is given by ...

  Sn = n(2a1 +(n-1)d)/2

For the sequence of numbers of bales, we have ...

  a1 = 123, d = -11, n = 7

so the total number of bales in 7 trips around the field is ...

  S7 = 7(2·123 +6(-11))/2 = 630

The total number of bales made is about 630.

_____

123 + 112 + 101 + 90 + 79 + 68 + 57 = 630

Lianne charged twice as much to walk a large dog than she did to walk a small dog. This week she had time to was 10 small dogs a
guapka [62]
Well she charged twice as much to walk large then small. Let s be small and l be large.
We we know that
l = 2s

we also know that she wants to make 100 so
xl + ys = 100

Where where x is number of large and y is number of small. it says she walked 10 small and 5 large so
5l + 10s = 100

substitute 2s for l because they are same value as shown in first equation I made
5 (2s) + 10s = 100
10s + 10s = 100
20s = 100
s = 5

we can now solve for l
l = 2s
l = 2 * 5
l = 10

So s is 5 and l is 10.
