where is the question....
the volume of a gas varies inversely as the pressure on it. if the volume is 240 cm^3 under a pressure of 30 kg/cm^2, what pressure must be applied to have a volume of 120cm^3
Answer:
V varies 1/P.
V=K/P.
K=VP.
K=240×30.
=7200.
Therefore 7200=VP.
so.....
7200=120P.
P=7200/120.
P=60kg/cm^2.
The diagram below represents the measurements of Jennie’s yard. The yard’s width is x feet shorter than its length. If the area of the yard is 540 square feet, how many feet shorter than the length is the width? A yard with a length of 30 feet and a width of (30 minus x) feet. Which equation represents the scenario? 30 + (30 – x) = 540 540 – 30 = 30 – x 30(30 – x) = 540 540 – (30 – x) = 30 : Please Help
Answer:
I got this answer from the comments and it was correct so the correct answer is C.
Step-by-step explanation:
Ty cco713.
The equation that represents the scenario is 540 = 30(30 - x)
Area of a rectangleA rectangle is a 2-D shape with 4 sides.The formula for calculating the area of the rectangle is expressed as:
A =lw
where:
l is the length
w is the width
Given the following parameters
l = 30ft
w = 30 - x
A = 540
Substitute
540 = 30(30 - x)
Hence the equation that represents the scenario is 540 = 30(30 - x)

Explain the difference between the associative addition and the commutative addition
Answer:
Associative states you can regroup numbers and you will get the same answer and the commutative property states that you can move numbers around and still have the same answer.
Example:
Commutative a+b=b+a
Associative a+ (b+c) = (a+b) +c= a+b+c

Answer:
Step-by-step explanation:
2(1/2 A + N = d)
A + 2N = 2d
A = 2d - 2N
Answer:
A = 2(d - N)
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] A + N = d ( subtract N from both sides )
[tex]\frac{1}{2}[/tex] A = d - N ( multiply both sides by 2 to clear the fraction )
A = 2(d - N)
The table below shows the price, in dollars, for the number of Rose's indicated.
Answer:
1. The relationship is proportional.
2. The cost for 30 roses is 90 dollars.
Step-by-step explanation:
1. The price (y) divided by the number of roses (x) equals 3, no matter what section in the table you try it on; y/x = 3. This means that the relationship is proportional.
Another way to explain this is x * 3 = y. For example, 3 roses * $3 = $9
2. We know that one rose costs $3. So you can multiply:
30 roses * $3 = $90

A fairly recent alternative to algebraic modeling is spreadsheet modeling, which, instead of relating various quantities with algebraic equations and inequalities, relates them in a spreadsheet with cell formulas.a) trueb) false
Answer:
True
Step-by-step explanation:
With the advent and proliferation of the use of computers, data can now be analyzed with the aid of spreadsheets. These spreadsheets such as the one found in Microsoft Excel are arranged in grids whereby, the rows are numbered and the columns are identified with alphabets. The data entered in the spreadsheet are guided by formulas which can be found on the formula tool bar.
The formula gives an insight into the calculation performed for the list of items provided in the grid. There are several mathematical functions that aid in the calculations, such as the SUM and DIV functions.

Which number in the group below is the largest? -12, -11, -9, -5, -15
Answer:
The largest is -5
Step-by-step explanation:
This is because when dealing with negatives, the closer to the zero, the larger the number.
Answer:
-5
Step-by-step explanation:
-5, because numbers that are closer to zero are larger than others that are farther away from 0.
These are the numbers in order from least to greatest: -15, -12, -11, -9, -5

4n - 9 = 2(5 + 2n).
Answer:
no solution
Step-by-step explanation:
start by
distributing the 2 on the right side of the equation
you should get 4n-9=10+4n
then you should try to combine like terms, start by subtracting the 4n on the left side from the one on the right
both of those should cancel out
leaving you with -9=10, which is obviously false, meaning there is no solution
I think it’s no solution.

Which number sentence states that x is at most 50?
A. x < 50
B. x < 50
C. x = 50
D.x > 50
E. x > 50
idk this one is kind of confusing me
Answer:
its A & B, x<50
Step-by-step explanation:
atmost means till 50.
atleast means more than 50.
The number sentence that states that x is at most 50 is option B: x ≤ 50.
In mathematical notation, the symbol "≤" means "less than or equal to." So, x ≤ 50 translates to "x is less than or equal to 50."
This means that x can be any value that is less than 50 or exactly 50.
Option A (x < 50) would mean "x is less than 50," excluding the value 50 itself.
Option C (x = 50) would mean "x is equal to 50," but it doesn't include any values less than 50.
Option D (x > 50) would mean "x is greater than 50," excluding the value 50 itself.
Option E (x ≥ 50) would mean "x is greater than or equal to 50," which includes values greater than 50, but it doesn't allow any values less than 50.
So, the correct choice to state that x is at most 50 (including the value 50) is option B: x ≤ 50.

Answer:
x = 1.5
Step-by-step explanation:
First, we distribute (get rid of parentheses):
6x - 3 - 3x = 5 - x - 2
Then, we simplify:
3x - 3 = 3 - x
Then, we combine like terms:
3x + x = 3 + 3
Then, we simplify again:
4x + 6
Finally, we divide 4 on both sides:
We got x = 1.5

HAS TO BE DONE BY TOMORROW - A positive integer is called snakelike if its digits alternately increase and decrease or vice versa. For example, 130 and 91727 are snakelike. However 123 is not snakelike (2 is greater than 1 but not 3) and 91727 is not snakelike (7 is greater than 1 but not 7)
A) How many 4-digit snakelike numbers contain each of the digit 1,2,3,4 exactly once
B) How many 3-Digit snakelike numbers have 6 as their middle digit
C) a 7-digit snakelike number starts with digit 9. Explain why it last digit cannot be 0
Answer:
A) 10
B) 39
C) the last digit must be greater than the previous digit. 0 is not greater than any other digit, so the last digit cannot be 0.
Step-by-step explanation:
A) Numbers of the form low, high, ... can start with digits 1 or 2, and the 3rd digit will be the other one. There 4 such numbers 1423, 1324, 2413, 2314. In addition, For a first digit of 2, the second digit may be 1, allowing 2143. Thus, there are 5 numbers starting with 1 or 2 and ending with 3 or 4.
There are 5 additional numbers that are the reverse of these.
There are 10 4-digit snake-like numbers containing 1–4 exactly once.
__
B) We assume a "3-digit number" will be in the range 100–999. That is, the leading digit will not be zero. If you allow a leading 0, the answer is different.
With 6 as a middle digit, the numbers 1–5 can be the first digit and the numbers 0–5 can be the last digit. Hence there are 5·6 = 30 numbers of the form low-6-low.
If the form is high-6-high, there are 3 possible first digits and 3 possible last digits, so 3·3 = 9 numbers of the form high-6-high.
There are 39 3-digit snake-like numbers with 6 as the middle digit.
__
C) A 7-digit snake-like number will alternate high-low, with high being the last digit. Hence the last digit must be higher than the previous digit, so cannot be 0.
Which value would make the statement true? StartFraction 2 Over question mark EndFraction greater-than StartFraction 4 Over 12 EndFraction 4 6 12 24
Answer:
4
Step-by-step explanation:
Given the expression 2/? > 4/12, to find the value of ? that will make the expression true, we will cross multiply first
On cross multiplying:
2×12 > 4 × ?
24 > 4 × ?
Divide both sides by 4
24/4 > 4×?/4
6 > ?
This means that ? < 6
The answer will be a value that is less than 6. According to the option, the only value less than 6 is 4. Hence the correct answer is 4.

Answer:-90
Step-by-step explanation:
If R is the midpoint of QS, QR = 8x – 51 and RS = 3x – 6, find QS.
Answer:
42 units
Step-by-step explanation:
If R is the midpoint of QS, then by definition, QR = RS. Since QR = 8x - 51 and RS = 3x - 6, set these equal to solve for x:
QR = RS
8x - 51 = 3x - 6
5x = 45
x = 9
Now that we know x = 9, we can plug this back into one of the expressions for QR or RS to find its length:
QR = 8x - 51 = 8 * 9 - 51 = 72 - 51 = 21
Since half of QS is 21, then the whole of QS is twice that:
2 * 21 = 42
The answer is thus 42 units.
