logs are stacked in a pile on the bottom row and 15 on the top row . there are 10 rows in all with each row having one more log
WITCHER [35]
Since there is a common difference of one, this is an arithmetic sequence of the form a(n)=a+d(n-1) which in this case is:

a(n)=15+1(n-1)

All arithmetic sequences have a sum which is equal to the average of the first and last terms time the number of terms, mathematically:

s(n)=(2an+dn^2-dn)/2  (that is just the result of ((a+a+d(n-1))(n/2)) )

Since a=15 and d=1 this becomes:

s(n)=(30n+n^2-n)/2

s(n)=(n^2+29n)/2 so

s(10)=(100+290)/2

s(10)=195 logs

Find the slope of (0,1) and (2,7)
gavmur [86]
Slope is \frac { y_{2} - y_{1}}{ x_{2} - x_{1}}

if we plug in your coordinates we get:
\frac { y_{2} - y_{1}}{ x_{2} - x_{1}} \\ \frac {7-1}{2-0} \\ \frac {6}{2} \\ 3

Therefore, the slope of (0,1) and (2,7) is 3.

Miguel bikes 23 km per hour and starts at mile 10. Gabby bikes 28 km per hour and starts at mile 0. Which system of linear equat
7nadin3 [17]
The correct answer is D) Miguel:  d=23t+10, Gabby d=28t

We multiply the speed of each person by t, the amount of time.  This is where the 23t in Miguel's equation and the 28t in Gabby's equation come from.  The starting point is added to this, which leads to 23t+10 and 28t+0 or 28t.

Zepler [3.9K]

Answer:

<u>28.8%</u> of the fruit she bought on Tuesday was apples.

Step-by-step explanation:

Given:

On Monday, a fruit vendor bought 80 pieces of fruit to sell at her market, 35%, percent of which were apples and the rest of which were oranges. On Tuesday, the vendor bought the same number of oranges, but she only bought 73 pieces of fruit.

Now, to find the percentage of apples among the fruit she bought on Tuesday.

So, on Monday the fruit vendor bought 80 pieces of fruit.

35%, percent of which were apples.

So, the number of apples in the fruit are:

35\%\ of\ 80\\\\=\frac{35}{100} \times 80\\\\=0.35\times 80\\\\=28\ apples.

Thus, there are 28 apples.

Now, the rest are oranges, so we find the number of oranges by subtracting   28 apples from 80 pieces of fruit:

80-28=52\ oranges.

As, there were 52 oranges in the fruit on Monday.

And, the vendor bought same number of oranges on Tuesday.

<u><em>So, total number of fruit pieces she bought on Tuesday was 73.</em></u>

Now, to get the number of apples she bought on Tuesday we subtract number of oranges from the total number of pieces of fruit:

73-52=21.

<u><em>Hence, the apples she bought on Tuesday was 21.</em></u>

Now, to get the percentage of fruit she bought on Tuesday was apples:

\frac{21}{73} \times 100\\\\=\frac{2100}{73} \\\\=28.8\%.

Therefore, 28.8% of the fruit she bought on Tuesday was apples.
