1/9 rounded to the nearest 1/2.
1/9 rounded to the nearest 1/2 is 0 because it is closer to 0 than to 1/2.
Explanation:When rounding 1/9 to the nearest 1/2, consider the fractions between 0 and 1 that are multiples of 1/2, which are 0 (or 0/2) and 1/2. Since 1/9 is closer to 0 than it is to 1/2, 1/9 rounded to the nearest 1/2 is 0. If you're trying to visualize this, picture a pie: 1/9 of a pie is a smaller slice than 1/2 of a pie.
To round a number to the nearest 1/2, you would choose the nearest fraction that is a multiple of 1/2. In this case, 1/9 is less than 1/4 (which is half of 1/2), hence it rounds down to 0, which represents no pie at all compared to half a pie.
When 2246 is subtracted from twice a certain number, the result is 10,000. What is the number?
The number is 6123.
Given,
When 2246 is subtracted from twice a certain number, the result is 10,000.
We are to find the number.
Let the number be M.
Now,
"When 2246 is subtracted from twice a certain number"
It can be written as:
2M - 2246
"the result is 10,000".
It can be written as,
2M - 2246 = 10,000
Now,
We have.
2M - 2246 = 10000
Solve for M.
2M - 2246 = 10000
2M = 10000 + 2246
2M = 12246
M = 12246 / 2
M = 6123
Thus the number is 6123.

Suzanne bought 50 apples at the orchard. She bought 4 times as many red then green apples. How many more red then green apples did she buy.
Suzanne bought 30 more red apples than green apples.
Given that Suzanne bought 50 apples, which are 4 times as many red then green apples.
We need to find how many more red apples then green apples did she buy.
To find the number of red and green apples Suzanne bought, we can set up an equation based on the information given.
Let's assume that Suzanne bought x green apples. Since she bought 4 times as many red apples as green apples, she must have bought 4x red apples.
According to the problem, Suzanne bought a total of 50 apples. So we can write the equation:
x (green apples) + 4x (red apples) = 50
Combining like terms, we have:
5x = 50
To solve for x, we divide both sides of the equation by 5:
x = 10
Now we know that Suzanne bought 10 green apples. To find the number of red apples, we can substitute this value back into our equation:
4x = 4 × 10 = 40
Suzanne bought 40 red apples.
To find the difference between the number of red and green apples, we subtract the number of green apples from the number of red apples:
40 (red apples) - 10 (green apples) = 30
Hence Suzanne bought 30 more red apples than green apples.

Gary’s is a small publishing company that publishes math books. The production costs include a one-time cost for editing the book, which is $1,050 for the book the company is currently working on (The Universe of Math). Once the book is in production, the only cost will be the variable cost of printing, which is $15 per book. The company will market the book at a price of $35. If you were to plot a graph of the profit generated by this book, what would the slope and the y-intercept represent?
Answer:
The y- intercept is -1,050 and the slope of the graph is 20.
Step-by-step explanation:
Consider the provided information.
The slope intercept form is:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y intercept.
The production costs include a one-time cost for editing the book, which is $1,050.
We need to find the y-intercept, here the y-intercept is the one-time cost of editing the book.
As we want to plot a graph of the profit so the cost will represented as negative.
Therefore, b = -1,050
Hence, the y- intercept is -1,050.
Now again consider the provided information.
The company will market the book at a price of $35 but it is given that the cost of printing, is $15 per book.
Thus, the slope is the difference of the selling price and production cost.
Or we can say that the slope is the profit per book sold.
Slope = m = 35 - 15 = 20
Hence, the slope of the graph will be 20.
The required equation of the graph is y=20x-1050

A real estate agent recieved a $17,500 commision on the sale of a $350,000 house on Walnut Street. The same agent recieved a $20,000 commission on the sale of a house on Center Ave. What was the sale price of the house on Center Ave? A: $100,000 B:$370,000 C: $400,000 D: $450,000
Answer:
Opton C: $400,000
Step-by-step explanation:
A real estate agent received a $17,500 commission on the sale of a $350,000 house.
We will calculate the percentage of the commission.
[tex]\frac{17,500}{350,000}\times 100[/tex]
= 0.05 × 100
= 5%
Let the value of the house on Center Ave be x
Therefore, 5% of x = $20,000
= 0.05x = 20,000
x = [tex]\frac{20,000}{0.05}[/tex]
x = $400,000
The sale price of the house on Center Ave is $400,000
