The volume of gas in a container at a constant temperature varies inversely as the pressure. If the volume is 32 cubic centimete
finlep [7]

Answer:

The new pressure is 4.27 pounds

Step-by-step explanation:

In this question, we have the volume varying inversely as the pressure;

Firstly, let's say the volume is V and the pressure is P

Mathematically;

V ∝ 1/P

Let us insert a constant of proportionality K

⇒ VP = K

Let's calculate the value of K

K = 32cm^{3} × 8 = 256 cm^{3} pounds

Now in the second scenario, pressure is unknown but we know the volume to be 60cm^{3}

Recalling;  VP = K

P = K/V = 256 cm^{3} pounds/60cm^{3} = 4.27 pounds

Sam has 2 brothers. His brothers are 5 cm shorter and 7 cm shorter than him. Sam's height is 140 cm. What is the median height o
pochemuha

Answer:

The median height of Sam and his brothers is 135.

Step-by-step explanation:

First, let's find the age of Sam's brothers:

B_{1} = 140 cm - 5 cm = 135 cm

B_{2} = 140 cm - 7 cm = 133 cm

The median height of Sam and his brothers is given by the middle number of the three values arranged from lowest to highest:

133   <u>135</u>   140                      

<em>Since the middle number is 135, then the median height is 135. </em>

Therefore, the median height of Sam and his brothers is 135.

I hope it helps you!

area of a triangle is 14x^5 + 63x^2. If the base is 7x^2, write an expression to represent the height ( x^2 means x square)
mr_godi [17]

Answer:

h=4x^3+18

Step-by-step explanation:

Given that,

The area of a triangle, A=14x^5 + 63x^2

Base, b=7x^2

We need to find the height of the triangle.

The formula for the area of the triangle is given by :

A=\dfrac{1}{2}\times b\times h\\\\\text{h is height}\\\\h=\dfrac{2A}{b}\\\\h=\dfrac{2\times (14x^5 + 63x^2)}{7x^2}\\\\h=\dfrac{2\times 7x^2(2x^3 + 9)}{7x^2}\\\\h=2(2x^3+9)\\\\=4x^3+18

So, the height of the triangle is 4x^3+18.
