Answer:
The new pressure P₂ is 3.3 atm
Step-by-step explanation:
Pressure of gas = 2.7 atm
Volume = 3.6 L
Temperature = 324 K
Now we are given that volume of the gas is kept constant.
Temperature is increased to 396 K
We need to find the pressure.
The formula used is: [tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]
We have P₁ = 2.7
T₁ = 324 K
T₂ = 396 K
P₂ = ?
Putting values in the formula and finding P₂
[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}\\\frac{2.7}{324}=\frac{P_2}{396}\\P_2=\frac{2.7}{324}\times 396\\P_2=0.0083 \times 396\\P_2=3.3[/tex]
So, the new pressure P₂ is 3.3 atm

Factorise fully 6x² - 15x
Answer:
3x(2x - 5)
Step-by-step explanation:
because you have x² that means that you have to timse x by x to get x².
6 divided by 15 gets you a decimal but both number goes into the 3 times table
Therefor 6x² - 15x = 3x(2x-5)
If you need to check just times 2x by 3x which would get you 6x² and 5 by 3x which would get you 15x
Answer:
3x(2x-5)

of liters of water are enough to water of the plants in the house, how much water is necessary to water all the plants in the house? Write a multiplication equation and a division equation for the situation, then answer the question. Show your reasoning.
Answer:
2/5 x ? = 4/3?
4/3 / 2/5= ?
Quick method is quick change flip, Change the division sign into multiplication and switch the values in the denominator and numerator of the second fractiom
4/3 x 5/2 = 20/6
simplify to 10/3
x or ? = 10/3
written as a mixed number is is 3 1/3

For a chemistry experiment 3/4 of an ounce of a certain chemical is needed. if a bottle of the chemical holds 96 ounces, how many times can the experiment be completed?
Answer:
The experiment can be completed 128 times from 96 ounce bottle of chemical.
Step-by-step explanation:
Given that:
Ounces of chemical hold by bottle = 96 ounces
Chemical used for experiment = 3/4 of an ounce = 0.75 ounce
Number of experiments = [tex]\frac{Chemical\ in\ bottle}{Chemical\ used\ for\ experiment}}[/tex]
Number of experiments = [tex]\frac{96}{0.75}[/tex]
Number of experiments = 128
Hence,
The experiment can be completed 128 times from 96 ounce bottle of chemical.
What is 8q+12=4(3+3q)
Answer:
q = 0
Step-by-step explanation:
8q + 12 = 4( 3 + 3q )
Distributive property
8q + 12 = 4 ( 3 + 3q )
8q + 12 = 12 + 12q
Inverse operations
8q + 12 = 12 + 12q
-8q -8q
12 = 12 + 4q
-12 -12
0 = q
q = 0
Answer:
Q = 0
Step-by-step explanation:
1. Expand.
8q + 12 = 12 + 12q
2.cancle 12 on both sides.
8q = 12q
3. Move all terms to one side.
8q - 12q = 0
4. simplify 8q - 12q to -4q.
-4q = 0
5. Divide both sides by -4.
q=0
therefor, the answer is q=0

6x + 2 - 8x + 7 = 4x + 1 A. 4/3 B. 3/4 C. -4/3 D. -3/4 oc A D B
Answer:
A
Step-by-step explanation:
Given
6x + 2 - 8x + 7 = 4x + 1 ← simplify left side
9 - 2x = 4x + 1 ( subtract 4x from both sides )
9 - 6x = 1 ( subtract 9 from both sides )
- 6x = - 8 ( divide both sides by - 6 )
x = [tex]\frac{-8}{-6}[/tex] = [tex]\frac{4}{3}[/tex] → A

The Slope of a Line
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The line shown in the image is horizontal, i.e. all of its points have the same y-coordinate regardless of their x-coordinate.
Take two random points on the line like (0,-2) and (2,-2), the slope is:
[tex]\displaystyle m=\frac{-2+2}{2-0}=0[/tex]
The slope is zero
