Sandy collects two shells at a time to Shawn collect for shells at a time and Sonya collect 10 shells at a time to have the same number of shells what is the least number of shells each friend must collect

Answers

Sandy collects 2 shells at a time

Shawn collects 4 shells at a time

Sonya collects 10 shells at a time.

Find the lowest possible number that they all have similar. Look at their factors

2 x 10 = 20

4 x 5 = 20

10 x 2 = 20

20 is the lowest number

hope this helps

seems that you are trying to say that:sandy collects 2 shells at a time (so she doesn't collect 1 or 3 at a time)shawn collects 4 shells at a timesonya collects 10 shells at a time

this is a problem to find the least common multipleone way is to list all the number of shells they can collectthe number of shells sandy can collect is 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28...
the number of shells shawn can collect is 4, 8, 12, 16, 20, 24, 28, 32...
the number of shells sonya can collect is 10, 20, 30, 40, 50...

when is the first common number?
it is 20so answer is 20 shells is the least number they must collect

the way to do it with math is thiswhat is least common mulitpule of 2,4, and 10?factor them2=24=2*210=2*5LCM contains the factors of eachso LCM=2*2*5=4*5=20LCM=20
so least number of shells needed to be collected is 20

Answer:

$\pm 1,\pm 2,\pm 3,\pm 4,\pm 5,\pm 6,\pm 10,\pm 12,\pm 15,\pm 20,\pm 30,\pm 60,\pm (1)/(2),\pm (3)/(2),\pm (5)/(2),\pm (15)/(2),\pm (1)/(3),$

$\pm (2)/(3),\pm (4)/(3),(5)/(3),\pm (10)/(3),\pm (20)/(3),\pm (1)/(3),\pm (2)/(3),\pm (4)/(3),\pm (5)/(3),\pm (10)/(3),\pm (20)/(3),\pm (1)/(4),\pm (3)/(4),\pm (5)/(4),$

$\pm (15)/(4),\pm (1)/(6),\pm (5)/(6),\pm (1)/(9),\pm (2)/(9),\pm (4)/(9),\pm (5)/(9),\pm (10)/(9),\pm (20)/(9),\pm (1)/(12),\pm (5)/(12),\pm (1)/(18),\pm (5)/(18),\pm (1)/(36)$

Step-by-step explanation:

The given polynomial is

$p(x)=36x^2-7x-60$

We need to find the potential roots of given polynomial according to the rational root theorem.

According to the rational root theorem, the potential roots are

$x=\pm (p)/(q)$

where, p is a factor of constant term and q is the factor of leading term.

In the given polynomial constant term is -60 and leading term 36.

Factors of 60 are ±1,±2,±3,±4,±5,±6,±10,±12,±15,±20,±30,±60.

Factors of 36 are ±1,±2,±3,±4,±6,±9,±12,±18,±36.

Now, the potential roots are

$\pm 1,\pm 2,\pm 3,\pm 4,\pm 5,\pm 6,\pm 10,\pm 12,\pm 15,\pm 20,\pm 30,\pm 60,\pm (1)/(2),\pm (3)/(2),\pm (5)/(2),\pm (15)/(2),\pm (1)/(3),$

$\pm (2)/(3),\pm (4)/(3),(5)/(3),\pm (10)/(3),\pm (20)/(3),\pm (1)/(3),\pm (2)/(3),\pm (4)/(3),\pm (5)/(3),\pm (10)/(3),\pm (20)/(3),\pm (1)/(4),\pm (3)/(4),\pm (5)/(4),$

$\pm (15)/(4),\pm (1)/(6),\pm (5)/(6),\pm (1)/(9),\pm (2)/(9),\pm (4)/(9),\pm (5)/(9),\pm (10)/(9),\pm (20)/(9),\pm (1)/(12),\pm (5)/(12),\pm (1)/(18),\pm (5)/(18),\pm (1)/(36)$

Answer:

This expression can not be factored with rational numbers.

The polynomial is not factor able with rational numbers.

A bag of apples weighs 7 7/8 pounds and a full bag costs $10.88. By weight 1/18 of the apples are rotten . What is the cost of the bag if the bad apples are removed?

Answers

Answer: Hello there!

We know that a bag of apples weighs (7 + 7/8) lb and costs $10.88

But 1/18 of the apples are rotten, if we remove the rotten apples, we still have the other 17/18 portion of the bag to pay.

then; if the full bag costs $10.88, how much does it cost a 17/18 of the bag?

this is (17/18)*$10.88 = $10.28

Then if you remove 1/18 of the apples, the bag costs 10.28 dollars.

notice that I did not use the weight of the apples, in a lot of math problems you will have more information than the needed, and you need to know when the information is useful and when it is not.

Try Analysing The Information Like This, Step by Step;

1. We know that a full bag of 7 7/8 pounds and is $10.88.
2. Now we subtract the bad apples 7 7/8-1/18= a (now we have no bad apples).
3. Part 'a' answer will give you a no. in pounds.
4. Part 'b' - we have to find out $10.88/7 7/8 - 1/18 / 2 to give you the answer.

I hope this helps, sorry I couldn't really help you :)
