P1/T1 = P2/T2 

<span>748 / 525 = P2/293 </span>

<span>P2 = 748/525 X 293 = 417.455 kPa </span>

Answer:

Therefore, the new pressure is 417.455 kPa

Step-by-step explanation:

As per general gas equation

\frac{P_{1}V_{1}}{T_{1} }=\frac{P_{2}V_{2}}{T_{2} }

If Volume of a gas is constant then equation is represented by

\frac{P_{1}}{T_{1} }=\frac{P_{2}}{T_{2} }

Here P_{1}=748kPa and T_{1}=525K

If T_{2}=293K then we have to calculate the value of P_{2}

Now we plug in the values in the equation

\frac{748}{525}=\frac{P_{2}}{293}

P_{2}=\frac{(748)(293)}{525}

P_{2}= 417.455 kPa

Therefore, the new pressure is 417.455 kPa

How do i finish this
ludmilkaskok [199]
Hi there!

To start off, you should not use this equation because it is incorrect to use for this problem.

Here's how you should solve it:

The base angles of an isosceles triangle is always equal. That means angle S also has a measure of 2x+2.

Now, add up all the angles.

(2x + 2) + (2x + 2) + (3x + 1) = 180

This is the proper equation. Now, open the parenthesis and combine like terms.

7x + 5 = 180

Now, subtract both sides by 5

7x = 175

Now, divide both sides by 7.

x = 25

To solve for angle R, plug in x=25 into 3x+1

3(25) + 1

= 76

The measure of angle R is 76 degrees.

Have an awesome day! :)

Math 3 help!<br>Expand f(x) = x^2-10x+2 in powers of x-1​
aleksandr82 [10.1K]

Answer:

f(x) = x^2-10x+2

f(-1)=(-1)^2-10(-1)+2

if it sad to salve

f(-1)=(-1)^2-10(-1)+2

-1f=1-10+2

-1f=7

/-1 /-7
