Answer: Pressure and gravity

The stars are formed by the dust and accumulation of gases present in the space. It typically formed by the fusion of the gases such as hydrogen, helium in the space. The pressure of the inner core of the star and the pressure exerted by the gases present outside the star influence the shape of the star. The celestial bodies of the universe like stars, planets and others are acted upon by the gravitational attraction. This is responsible for keeping all the gaseous molecules present in the star in shape.

zzz [600]

Answer:

1/4 feet long should each pieces be.

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity of 1 such as 3 miles per second or 4 km per hour

As per the statement: Becky has a board that is 2 and 3/4 feet long.

⇒ Length of a board = $2\frac{3}{4} =\frac{11}{4}$ feet

Also, she need to cut the board into 11 pieces.

by unit rate definition:

$\text{Unit rate per pieces} = \frac{\frac{11}{4} }{11}$

$\text{Unit rate per pieces} = \frac{11}{4} \times \frac{1}{11} = \frac{1}{4}$

Therefore, 1/4 feet long should each pieces be.

Solve the equation for the indicated variable. Please help ASAP!!!!! :(<br> A=(730x)/(d^2) for x

zvonat [6]

First let's get rid of the $d^2$ in the denominator of the fraction on the right side of the equation. This will help to get only $x$ and a coefficient on one side of the equation:

$A = \dfrac{730x}{d^2}$

$d^2A = 730x$

Now, simply divide by 730 to find $x$ :

$d^2A = 730x$

$\boxed{\dfrac{d^2A}{730} = x}$
