Yi and Sue play a game. They start with the number $42000$. Yi divides by a prime number, then passes the quotient to Sue. Then Sue divides this quotient by a prime number and passes the result back to Yi, and they continue taking turns in this way.
For example, Yi could start by dividing $42000$ by $3$. In this case, he would pass Sue the number $14000$. Then Sue could divide by $7$ and pass Yi the number $2000$, and so on.
The players are not allowed to produce a quotient that isn't an integer. Eventually, someone is forced to produce a quotient of $1$, and that player loses. For example, if a player receives the number $3$, then the only prime number (s)he can possibly divide by is $3$, and this forces that player to lose.
Who must win this game, and why?
Answer:
The first person starting will always lose.
Step-by-step explanation:
First, I will the prime factorization of 42000. After finding the prime factorization of 42000, I will count the number of primes in the prime factorization. After that, we will find which round the person will lose.
Prime Factorization of 42000: 2*2*2*2*3*5*5*5*7
Number of Primes in List: 9
The person losing: The person on the 9th turn will lose.
The person on the 9th turn is Yi. Therefore, no matter how Yi or Sue keeps mixing the order of the numbers, Yi will always lose.
I hope this helps!

six is greater than or equal to the quotient of a number y and 2.5
The statement 'six is greater than or equal to the quotient of a number y and 2.5,' can be converted into the inequality 6 >= y/2.5. Solving for y by multiplying both sides by 2.5 gives y <= 15. Therefore, any number y that is 15 or less will satisfy this inequality.
Explanation:The question provided, 'six is greater than or equal to the quotient of a number y and 2.5,' requires manipulation of an inequality in mathematics to find the potential values of y. To represent this in mathematical terms, one could write the inequality as 6 ≥ y/2.5. From here, it is a simple matter of isolating y by multiplying both sides of the inequality by 2.5, which results in y ≤ 15. Therefore, any number y that is less than or equal to 15 satisfies the inequality.

which of the following is equal to 5 4/9 5.49 5.25 7.25 5.4
Answer:
5.4
Step-by-step explanation:
We are given that

We have to find the value which is equivalent to given fraction number.
[tex]5\frac{4}{9}=\frac{45+4}{9}[/tex]
[tex]5\frac{4}{9}=\frac{49}{9}[/tex]
When we divide 49 by 9 then we get

At the beginning of the year, Adrian's savings account balance was $28. Each week, he deposits another $15 into that account, and he doesn't spend any of his savings.
Is his savings account balance proportional to the number of weeks since the start of the year?
Answer:
The given condition is not proportional.
Step-by-step explanation:
At the beginning of the year, Adrian's savings account balance was $28.
Let Adrian invests for 'x' weeks.
So, total amount will becomes :
[tex]28+15x[/tex]
Since 4 weeks = 1 month, it will represent a linear equation only.
Linear functions have a constant rate of change and describe a straight line on a graph. So, this is not proportional.
The given equation is in the form y = mx + b, so its linear. For the equation to be proportional, it should be in the form of y = kx.

What is scientific notation?It is the way of writing a large number between 1 to 10 with a power of 10.
Example:
1.2 x 10² is in scientific notation.
9.1 x 10³ is in scientific notation.
We have,

Now,
We will make 1662.5 into a number between 1 and 10.
1662.5
= (1662.5/1000) x 1000
= 1.6625 x 10³

Rewrite as a simplified fraction 1.1 3 =?
The requried 1.1 3 can be written as a simplified fraction of 44/333.
What is the fraction?A fraction is a mathematical concept that can be used to express a portion of a whole or a number that can be written as the ratio of two integers. In a fraction, the top number is referred to as the numerator, while the bottom number is referred to as the denominator.
Here,
To rewrite 1.1 3 as a simplified fraction, we can first recognize that the repeating decimal can be represented as a fraction using a geometric series.
Let x = 0.133. Then, we can multiply both sides of this equation by 1000 to obtain
1000x = 133.333...
Next, we can subtract x from 1000x to obtain
999x = 133.333... - 0.133...
Simplifying the right side gives
999x = 133.2
Finally, dividing both sides by 999 gives
x = 133.2 / 999 = 44 / 333
Therefore, 1.1 3 can be written as a simplified fraction of 44/333.

Plzzzz help me
Plz :(:
Answer:
Part (A) the difference is 2,415 feet.
Part (B) the difference is 3,124 feet.
Part (C) the difference is 627 feet.
Part (D) the difference is 8 feet.
Step-by-step explanation:
Consider the provided table:
Part (A) The difference between the highest elevation in Alabama and lowest elevation in Louisiana.
highest elevation in Alabama is 2,407 and Lowest elevation in Louisiana is –8
Subtract the lowest elevation in Louisiana from the highest elevation in Alabama as shown:
2,407 – (–8 )= 2,407 + 8 = 2,415
So, the difference is 2,415 feet.
Part (B) the difference between the lowest elevation in New Mexico and the lowest elevation in California.
Lowest elevation in New Mexico is 2,842 and the lowest elevation in California is –282.
Subtract the lowest elevation in California from the lowest elevation in New
Mexico as shown.
2,842 – (–282) = 2,842 + 282 = 3,124
So, the difference is 3,124 feet.
C) The difference between the highest elevation in Florida and the lowest elevation in California.
Highest elevation in Florida is 345 and the lowest elevation in California is –282.
Subtract the lowest elevation in California from the highest elevation in Florida as shown.
345 – (–282) = 345 + 282 = 627
So, the difference is 627 feet.
Part (D) The Difference between the lowest elevation in Alabama and the lowest elevation in Louisiana.
Lowest elevation in Alabama is 0 and the lowest elevation in Louisiana is –8.
Subtract the lowest elevation in Louisiana from the lowest elevation in Alabama.
0 – (–8) = 0 = 8
So, the difference is 8 feet.
