How many 3/4 pound packages can you make with 6 pounds of sunflower seeds ?

Answers

Answer 1
Imagine first splitting 6 wholes up into fourths. That means that, for each whole (each 1) in 6, we're creating 4 equal slices. This gives us 4 x 6 = 24 total slices, which we call fourths. How many groups of 3 fourths (3/4) can you make out of those 24 fourths (24/4)? If we throw aside the label fourths for a minute, in general, if we have 24 things, how many groups of 3 things can we make out of those? Well, our answer there would just be 24 ÷ 3 = 8 groups.

The same thing applies to fourths. If we have 24/4, and we divide it by 3/4, we get 24 ÷ 3 = 8 groups again, so our answer is 8 3/4-pound packages.

What is the mean,median,mode(s) an range if the numbers are 15,30,17,15,24,31,15

Answers

The mean is 21.  The median is 15.  The mode is 15.  The range is 16.

Hello There!

Mean: Average of numbers in a set of data.

STEP 1: Add the numbers together. In this case, we would add

15 + 30 + 17 + 15 + 24 + 31 + 15 = 147

STEP 2: Divide the sum by the number of digits you added. We would divide

147 "sum of numbers" by 7 "number of digits" and we would get an answer of  

21.

The mean for the set of data is 21

Median: The middle number when all the numbers are listed in order.

To find the median, we would put the lowest number on the left and the biggest number on the right and continue to go from least top greatest.

-Least To Greatest-

15-15-15-17-24-30-31

In our set of numbers, we cross out one number from the left and the right each time until we come across one number in the middle. The number that is in the middle in 17.

The median for this set of data is 17

Mode: The number that occurs most often in a set of numbers.

15-15-15-17-24-30-31

Since the number 15 occurs three times, the mode for the set of data is 15.

The mode for this set of data is 15

Range: The difference between the highest and the lowest number.

15-15-15-17-24-30-31

The highest number in the set of numbers is 31 and the lowest number in this set is 15.

31 - 15 = 16

The range for this set of data is 16

One wintry week a ski town got 15 1/2 inches of snow. On Monday the town got 2 3/4 inches on Tuesday it got 1 1/2 times as much and on Wednesday it got 7/8 inch. How much snow did the town get for the rest of the week

Answers

On Monday the town got 2 3/4 (2.75) inches of snow.
On Tuesday it got 1 1/2 (1.5) times as much: 2.75 x 1.5 = 1.375 (inch)
⇒ On Tuesday the town got 1.375 inch of snow.
On Wednesday it got 7/8 (0.875) inch of snow.
After Monday, Tuesday and Wednesday, the town got:
2.75 + 1.375 + 0.875 = 5 (inches of snow)
For the rest of the week, the town got:
15 1/2 - 5 = 10 1/2 = 10.5 (inches of snow)

A car leaves a city with a speed of 90 mph. Three hours later and our of the same city another car in pursuit of the first leaves with a speed of 120 mph. Find the time it takes the scond car to reach the first.

Answers

The second car is 30 minutes

The time it takes the second car to reach the first is 9 hour.

What is speed?

Speed can be calculated as the ratio of distance traveled to the time taken

We are given that car leaves a city with a speed of 90 mph. Three hours later and our of the same city another car in pursuit of the first leaves with a speed of 120 mph.

Consider t be the time since the first car leaves

Distance of first car = 90t

Distance of second car:

120(t - 3)

Therefore, 90t = 120(t - 3)

90t = 120t - 360

360 = 30t

t = 12

The second car takes 12-3 = 9 hours to reach it

Nicholas has a larger tropical fish collection. He gives 2/3 of his fish to a high school. Then he gives 2/5 of the remaining fish to another school. In the end he has 30 fish left. How many fish Nicolas have at first?

Answers

Let the initial count of his fish be n.

He gives away 2/3 of these fish:  2n/3, leaving n/3 fish.

He gives away 2/5 of these remaining n/3 fish:  (2/5) times (n/3), or 

2n
--- , meaning that (3/5) times (n/3) fish are left.
15

(3/5)(n/3) = n/5 fish left = 30 fish.  Thus, n = 150 fish.

Be certain to check this answer!
Final answer:

To find the original number of fish in Nicholas' collection, work backward from the information provided on how many fish he has left after donating to the schools.

Explanation:

A school bought $548 in basketball equipment and uniforms costing $29.50 each. The total cost was $2,023. Write an equation you can use to find the number of uniforms the school purchased.

Answers

548 + 29.5x=2023 should be the answer
($2,023-$548) / $29.50 = 50

What the equation means: Since we already know they spent $548 in basketball equipment, we can subtract that from the total cost to find out how much they spent for the uniforms. After that, we have to divide the money used to buy the uniforms by the cost of each uniforms. Your final answer would be 50 uniforms.

Alice read a total of 36 books over 6 months. After belonging to the book club for 14 months, how many books will Alice have read in all?

Answers

Well if she read 36 books in 6 months, we can conclude that she reads 6 books per month. So if we take 6 * 14, we'll get 84.

She read 84 books in 14 months
36 books = 6 months.
Divide both sides by 6.
6 books = 1 month is Alice’s reading average.
6 books x 14 months = 84 books

Alice will have read 84 books in 14 months.

Saline solution A is 10% strength and saline solution B is 5% strength. I have an order for 6 litres of an 8% saline solution. To fill the order how many litres of solution A should be diluted with solution B? (Hint. Assume a 1% solution contains r grams of salt per litre.)

Answers

Let x = volume of saline solution A,
y = volume of saline solution B.

We're going to set up two equations. 
Firstly, x + y = 6. That gives us y = 6 – x     (1)

Second, 0.1x + 0.05y = 0.08•6, 
or 0.1x + 0.05y = 0.48               (2)

Substitute (1) into (2):
0.1x + 0.05(6 – x) = 0.48
0.1x + 0.3 – 0.05x = 0.48
0.05x + 0.3 = 0.48

Subtract 0.3 from both sides:
0.05x = 0.18
x = 3.6
Then y = 6 – 3.6 = 2.4

So we have to use 3.6 litres of solution A and 2.4 litres of solution B.


18/5 (or 3.6) liters of solution A should be diluted with solution B.

The agent withdraws 30% of his 10631.25 to pay for a trip to Montego bay, Jamaica. He hotel costs $350 per night for five nights plus an 8.5% room tax. How much does the agent have remaining

Answers

I believe the agent has $1,290.63 left. 

Because... 30% of 10,631.25 is $3,189.38( the exact was 3,189.375 but I rounded up). That's how much the agent has. Since it is $350 a night, 350 x 5= $1,750.00. Then you add the 8.5% to the $1,750 and you get $1,898.75.  That will be the total amount of money he will spend. So you will have to subtract $1,898.75 from $3,189.38 and the amount is $1,290.63. The remaining amount is $ 1,290.63.   I hope this helps :)

The number of shirts Kelly has to choose from is 2, namely Redshirt and Pink shirt. Computed using the Cartesian Product of sets.

What is the Cartesian Product of two sets?

The cartesian product of two sets A and B is a set containing ordered pairs (x, y), for every x ∈ A, and every y ∈ B.

How to solve the question?

In the question, we are informed that Kelly is picking out an outfit to wear. The organized list below represents the sample space of all possible outfits.

Redshirt – Black pants

Redshirt – White pants

Pink shirt – Black pants

Pink shirt – White pants

We are asked to find the number of different color shirts Kelly has to choose from.

Assuming the sample space to be the Cartesian Product of the set of shirts and set of pants, we can write the set of shirts as the first element of every ordered pair to get:

Set of Shirts = {Redshirt, Redshirt, Pink Shirt, Pink Shirt}.

Removing the repeating terms, we get:

Set of Shirts = {Redshirt, Pink Shirt}.

Thus, the number of shirts Kelly has to choose from is 2, namely Redshirt and Pink shirt. Computed using the Cartesian Product of sets.

After 4 apples were added to a sack, there were 3 times as many apples in the sack as before. How many apples were in the sack before the addition?

Answers

Hello!
So, your equation for this problem would be—
x+4=3x
To solve this equation, you need to move the variables (x) to only one side of the equation.
So, you would use the Subtraction Property of Equality.
x+4=3x
-x -x
—————
4=2x
Now, your new equation is 4=2x.
Using the Commutative Property, we can reverse this to—
2x=4
Your next step is to find X. To do this, we can divide each side by 2.
2x=4
———
2 2

____

2/2=1. 4/2=2
Thus your new equation is—

X=2.
As a conclusion, there were 2 apples in the sack before you added the extra ones.

To check this, you could do
2+4= 6
6/3= 2

There were 2 apples originally in the sack.
