The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the

Inessa [10]

Answer:

Step-by-step explanation:

If y is directly proportional to x, then the formula for that is a linear one:

y = kx, where k is the constant of proportionality. In our situation, if the pressure is directly proportional to the temp, then our formula is

P = kT. We need to find that value of k. Plug in what we have:

6 = k(440) so

k = .01363636 or as an equivalent fraction,

$k=\frac{3}{220}$

Now that have that value of k, we can use it in the formula again, this time with a different value for T to solve for P.

$P=(\frac{3}{220})380$ so

P = 5.181818 or as an equivalent fraction,

$P=\frac{513}{100}$

The volume of a rectangular box is 2x(2x + 5)(2x – 3). (Drawing is not to scale.)

Anarel [89]

Answer:

Option B. The volume is the product of the area of the base, 2x(2x + 5), and the height, 2x – 3

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The volume of a rectangular prism is equal to

$V=BH$

where

B is the area of the base of the prism

H is the height of the prism

In this problem we have

The area of the base B is equal to

$B=2x(2x+5)\ units^2$

The height H is equal to

$H=2x-3\ units$

therefore

The volume is equal to

$V=2x(2x+5)(3x-3)\ units^3$

The volume is the product of the area of the base, 2x(2x + 5), and the height, 2x – 3
