Answer:
The equation to find the answer is .
It has been 5 days since Karen has set her watch.
Step-by-step explanation:
Given:
Karen set her watch 1 second behind
So we will consider;
First term 'a' = 1 second
Also Given :
it falls behind another 2 seconds every day.
So we can consider;
Common difference = 2
We need to find number of days it has been 9 seconds since Karen last set her watch
Solution:
Let number of days be represented by 'n'.
Also Let
Now By Applying formula for Arithmetic Progression we get;
Substituting the given values we get;
Hence The equation to find the answer is .
On Solving the above equation we get;
Subtracting both side by 1 we get;
Now Dividing both side by 2 we get;
Adding 1 on both side we get;
Hence It has been 5 days since Karen has set her watch.
Answer:
She sell <u>2.075 kilograms</u> of pears at the farmer's market.
Step-by-step explanation:
<u><em>There is a mistake in the question some data is missing, so the correct question is below: </em></u>
<em>A farmer sells 8.3 kg of apples and pears at the farmer's market. 3 /4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?</em>
Now, to find the kilograms of pears.
Total weight of apples and pears = 8.3 kg.
Weight of apples = of 8.3 kg.
So, to get the weight of apples:
Thus, the weight of apples = 6.225 kg.
Now, to get the weight of pears we subtract the weight of apples from the total weight of apples and pears:
Therefore, she sell 2.075 kilograms of pears at the farmer's market.
