The number in which the value of the digit in the thousand place as one-tenth the value of the digit in the ten-thousand place is 44,000.
In 44000, the value of each place is 1/10 the value of the place before it as you move to the right in the place value chart. As a result of moving one place to the left, the value of the digit in the number 44,000's ten thousands place is 10 times greater than that of the digit in the thousands place.
In mathematics, place value refers to a digit's location within a number. A number has a slot for each digit. The placement of each digit will be enlarged when we represent the number in general form.
These positions begin at the unit place, often known as the individual's position. Units, tens, hundreds, thousands, ten thousand, one hundred thousand, and so on are the place values of a number's digits from right to left.

Last year, students planted 8 tomato plants and 16
garden. This year, the students planted
pepper plants in a school
15 tomato plants. They want to have the
same ratio of tomato plants to pepper plants as last year. Pepper plants cost
$4.33 each. What is the cost, in dollars, of the pepper plants for this year's garden?
Answer:
Step-by-step explanation:
From the ratio gotten, the total cost of the pepper will be $129.90.
How to solve a ratio
Since the students planted 8 tomato plants and 16 pepper plants in a school garden. The ratio will be:
= 8/16 = 1:2
This year, the students planted 15 tomato plants, the number of pepper will be:
= 15 × 2 = 30
Since pepper plants cost $4.33 each, the total cost will be:
= 30 × $4.33
= $129.90

(LOTS OF POINTS) The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $5500 to rent trucks plus an additional fee of $175.50 for each ton of sugar. The second company charges $4995 to rent trucks plus an additional fee of $200.75 for each ton of sugar.
a) For what amount of sugar do the two companies charge the same?
b) What is the cost when the two companies charge the same?
The amount of sugar that both companies would charge the same is 20 tons.
The cost when the two companies would charge the same is $9010.
What is the amount of sugar that both companies would charge the same?The linear equation that represents the total charge of the companies : cost to rent truck + (ton of sugar x cost per ton)
The linear equation that represents the total charge of the first company : $5500 + ($175 x s)
$5500 + $175s
The linear equation that represents the total charge of the second company : $4995 + ($200.75 x s)
$4995 + $200.75s
When the two companies charge the same, the two linear functions above would be equal.
$4995 + $200.75s = $5500 + $175s
In order to determine the value of s, take the following steps:
200.75s - 175.50s = $5500 - $4995
25.25s = 505
s = 505 / 27.25
s = 20
In order to determine when the cost of the two companies would be the same, substitute for s in either of the above linear functions.
$5500 + $175.50(20)
$5,500 + 3510 = $9010

What inequality does the number line show?
Write your answer starting with
x (example: x < 3)
Answer:
x < 5
Step-by-step explanation:
the dot is empty so we don’t consider 5
The coloured arrow continues to the left so we use this symbol : < (minor)
x<5
The inequality for the number line show is x<5.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We can see that the inequality starts from 5 moves towards 2.
As, the starting of number line have open dot which shows we cannot include 5.
So, the inequality will have sign '<'.

I hope this helps!
Answer:
B. False
Step-by-step explanation:
You want to know if (x -2) is a factor of 5x² -6x +4.
RemainderThere are a couple of ways you can determine whether (x -2) is a factor. One is to look at the polynomial value at x=2:
5x² -6x +4 = (5x -6)x +4 = (5(2) -6)(2) +4 = 4(2) +4 = 12
The value is not 0, so (x -2) is not a factor.
Other factorAnother way to tell is to determine what the other factor would be.
The product of roots is the ratio c/a = 4/5 in the polynomial. If 2 is a root, then (4/5)/2 = 2/5 is the other root. That would mean the factorization of the polynomial is ...
(5x -2)(x -2) = 5x² -12x +4 . . . . . . not the same polynomial
The polynomial 5x² -6x +4 does not have a factor (x -2).
GraphThe graph of the polynomial has no x-intercepts, so (x -2) cannot be a factor.
Select all of the following that represent direct variation.
1. y = 5x
2. y = 2x + 1
3. 3 = xy
4. b = 1/2a
5. y= 2/x
6. m = 5n
The equations, y=5x, b = 1/2 a, m=5n are direct variations.
What is direct variation?A sort of proportionality known as "direct variation" occurs when one quantity directly changes in response to a change in another quantity. This suggests that if one quantity increases, the other quantity will also increase proportionately. Similar to the last example, if one quantity declines, the other amount also declines. The link between direct variation and the graph will be linear, resulting in a straight line.
We know that any equation, which can be expressed in the form of y=kx, can be called a direct variation.
y = 5x is in the form of y = kx, where k =5, hence this is a direct variation
y = 2x + 1 is not in the form of y = kx, hence this is not a direct variation
xy = 3 is not in the form of y = kx, hence this is not a direct variation
b = 1/2 a is in the form of y = kx, where k =1/2, hence this is a direct variation
y = 2/x is not in the form of y = kx, hence this is not a direct variation
m = 5n is in the form of y = kx, where k =5, hence this is a direct variation
Thus, y=5x, b = 1/2 a, m=5n are direct variation

15 PTS I NEED HELP IMMEDIATLEY!! A textbook store sold a combined total of 447 biology and sociology textbooks in a week. The number of sociology textbooks sold was 63 less than the number of biology textbooks sold. How many textbooks of each type were sold?
Answer:
biology = 255 ; sociology = 192
Step-by-step explanation:
b + s = 447
s = b - 63
b + b - 63 = 447
2b = 447 + 63
2b = 510
2/2 b = 510/2
b = 255
s = 255 - 63
s = 192
Answer: 192 sociology textbooks, 255 biology textbooks
Step-by-step explanation:
Let the number of biology be x, and the number of sociology be x
The number of the sociology textbook is x+63
So the equation is
x + x + 63 = 447
2x = 384
x= 192 sociology textbooks
To find the number of biology textbooks, just take 447- 192 = 255 biology textbooks

Find h(8)-f(-7)
The function operation h(8) - f(-7) of the functions f(x) = -4x+1, and h(x) = 19-3x is -34.
What is the function operation h(8) - f(-7) in the given functions?A function is simply a relationship that maps one input to one output.
Given the data in the question;
f(x) = -4x + 1g(x) = x² - 8x + 21h(x) = 19 - 3xh(8) - f(-7) = ?First, solve for the output value of h(8) by replacing x with 8 and simplify.
h(x) = 19 - 3x
h(8) = 19 - 3(8)
h(8) = 19 - 24
h(8) = -5
Next, solve for the output value of f(-7) by replacing x with -7 and simplify.
f(x) = -4x + 1
f( -7 ) = -4( -7 ) + 1
f( -7 ) = 28 + 1
f( -7 ) = 29
Now, replace the function designators with the actual output values.
h(8) - f(-7) = -5 - ( 29 )
h(8) - f(-7) = -5 - 29
h(8) - f(-7) = -34
Therefore, the output of the function operation h(8) - f(-7) is -34.

After the dilation, the new volume of the cube is 125 times the original volume of the cube.
How does the new volume compare to the original volume?Remember that for a cube of sidelength S, the volume is written as:
V = S^3
If we apply a dilation of scale factor 5 to the cube, then the new sidelength of the cube is 5*S
Replacing that in the volume formula we will get the volume of the dilated cube, it is:
V' = (5*S)^3
V' = 5^3*S^3
V' = 125*S^3
Where S^3 is the original volume, so we can write:
V' = 125*V
So the new volume is 125 times the original volume.
