the space station has an average orbit of 250 miles above the earth. how many pennies would it take to make a stack that high? p
hram777 [196]

Answer:

264694796.312

Step-by-step explanation:

A penny is 0.0598 inches (1.52 mm) in thickness. (0.75 is the diamiter).

Hear me out. Now we gotta convert it to miles to divide 250 by the number  (there's 6.21371e-7 miles in one mm). first convert the mm to inches (by dividing the length value by 63360). We get 9.444842171717e-7 or 9.44484e-7 for a shorter form. Last step 250/9.444842171717e = 264694796.312.

Oh btw I'm not very sure on this answer correct me please if I'm wrong.

Solve for g. <br>what is g equal to?​
sweet [91]

Answer:

\displaystyle g=\frac{4\pi^2l}{T^2}

Step-by-step explanation:

<u>Equation Solving</u>

Given the equation

\displaystyle l=\frac{gT^2}{4\pi^2}

It's required to solve it for g. Let's swap sides of the equation:

\displaystyle \frac{gT^2}{4\pi^2}=l

Multiply by 4\pi^2 to remove the denominator:

\displaystyle gT^2=4\pi^2l

Divide by T^2

\boxed{\displaystyle g=\frac{4\pi^2l}{T^2}}

Vera_Pavlovna [14]

Answer:

The length and the width of the garden is equal to l=8\ ft

Step-by-step explanation:

Let

l -----> the length

w----> the width

we have

l=\frac{64}{w} ------> equation A

If the garden is a square

then

l=w

substitute in the equation A

l=\frac{64}{l}

l^{2}=64

square root both sides

l=8\ ft

therefore

The length and the width of the garden is equal to l=8\ ft
