Answer:

She sold 5.775 kilograms of pears at the farmer's market.

Step-by-step explanation:

Let's first determine the information that the question gives us, and what we need to find.

Given:

The farmer sold 7.7 kilograms of apples and pears

1/4 of the weight is apples

The rest of the weight is pears

Find:

Kilograms of pears that the farmer sold

Start by finding the fraction of the whole weight that was pears...

1-\frac{1}{4}=\frac{4}{4}-\frac{1}{4}=\frac{3}{4}

Now, find 3/4 of 7.7...

\frac{3}{4}(7.7)=\frac{23.1}{4}=5.775\ kg

She sold 5.775 kilograms of pears at the farmer's market.

The table shows the number of minutes Garrett practiced his trombone each week in one month. Week Number of Minutes Practiced 1
vredina [299]

Answer:

\bar X= \frac{\sum_{i=1}^n X_i}{n}

The reason is because we assume that each week have the same weight and replacing we got:

\bar X= \frac{190+163+327+205}{4}= 221.25

And the best option would be:

D. 221.25

Step-by-step explanation:

For this case we have the following data given

Week       1       2         3       4

Minutes  190   163   327   205

For this case we can find the mean with the following formula:

\bar X= \frac{\sum_{i=1}^n X_i}{n}

The reason is because we assume that each week have the same weight and replacing we got:

\bar X= \frac{190+163+327+205}{4}= 221.25

And the best option would be:

D. 221.25

Answer: number 3 is 32 number 4 is 40 minutes

Step-by-step explanation:You see in number 3 it says a millipede has 14 more legs than a caterpillar. Also it states the total of the legs are 46. This means you must subtract. 46-14 is equal to 32. And for number 4 it states the total time of all her classes are 1 hour and 10 minutes. The yoga class is 30 minutes longer. This means you must subtract those 30 minutes from the 1 hour and 10 minutes. 1 hour and 10 minutes- 30 minutes is equal to 40 minutes. This is the answer.

Hope this helps!!

Sam has $440 in $20, $10, and $5 dollar bills. The number of twenties, tens and fives are consecutive integers in this order. Ho
Ludmilka [50]

Answer: There are 12 bills for $20, 13 bills for $10 and 14 bills for $5.

Step-by-step explanation:

Let the number of twenties be x

Let the number of tens be x+1

Let the number of fives be x+2

Amount from twenties will be given as

20\times x=20x

Amount from tens will be given as

10\times (x+1)=10x+10

Amount from fives will be given as

5\times (x+2)=5x+10

According to question,

20x+10x+10+5x+10=440\\\\35x+20=440\\\\35x=440-20\\\\35x=420\\\\x=\frac{420}{35}\\\\x=12

So, there are 12 bills for $20, 13 bills for $10 and 14 bills for $5.
