I think f is the right answer because of how 128/4 is 3 and you need to find the area of the room.

Determine the temperature of 2.6 moles of gas contained in a 5.00-L vessel at a pressure of 1.2atm.

strojnjashka [21]

Answer:

28.108 K.

Step-by-step explanation:

Given: Pressure (P)= 1.2atm

Number of moles (n)= 2.6 moles

Volume (V)= 5.00-L

Now finding the temperature (T).

Formula; T= $\frac{P\times V}{n\times R}$

R is a constant factor which makes other factors work together.

There is a numerical value for R which we use is $0.0821 \times \frac{L.atm}{mole.K}$

∴ Temperature (T)= $\frac{1.2\times 5}{2.6\times 0.0821 \frac{L.atm}{mol.K} }$

⇒ Temperature (T)= $\frac{6}{0.21346} = 28.1083\ K$

∴ Temperature is 28.108 K

SOMEONE HELP ME PLEASE WITH THESE PROBLEMS AND PLEASE SHOW YOUR WORK FOR 50 points and BRAINLIEST THANK YOU

ELEN [110]

<u>Answer</u>:

13. $6x^7 y^7$ || 14. $\frac{25x^4}{y^6}$

<u>explanation</u>:

13.

$\frac{12x^9 y^5}{2x^2 y^-2}$

$6x^{9-2} y^{5--2}$

$6x^7 y^7$

14.

$(\frac{5y^{-3} }{x^{-2} } )^{2}$

$(\frac{5y^{-3} }{x^{-2} } )(\frac{5y^{-3} }{x^{-2} } )$

$\frac{\frac{25}{y^6}}{\left(x^{-2}\right)^2}$

$\frac{\frac{25}{y^{-6} }}{\left(x^{-4}\right)}$

$\frac{25x^4}{y^6}$

First to answer gets BRAINLEST<br><br> Which graphs show continuous data select all correct answers

solniwko [45]

<h2>Greetings</h2>

Answer:

Graph number 1 and 3

Step-by-step explanation:

This is because continuous data is shown by drawing a line that means the pencil doesn't have to be taken off the page. Seeing as these two graphs are the only two with lines drawn, it means they are graph number 1 and 3.

A coordinate plane with a line passing through (negative 3, 2) and (0, 3)

Arturiano [62]

Let's check

$\\ \sf\longmapsto Slope=m=\dfrac{3-2}{0+3}=\dfrac{1}{3}$

Y intercept is 3✓

Now

let f(x) be y

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto y=\dfrac{1}{3}x+3=f(x)\checkmark$

Why does the formula for area of a triangle makes sense.

galben [10]

Answer: bh=4×5=20b, h, equals, 4, times, 5, equals, 20 square units, so the area of the triangle is \dfrac 12 bh = \dfrac 12 \times 4 \times 5 = 10

bh=

×4×5=10start fraction, 1, divided by, 2, end fraction, b, h, equals, start fraction, 1, divided by, 2, end fraction, times, 4, times, 5, equals, 10
