First multiply the equation by r 
f*r=(mv^2) 
then divide by m f*r/gm=v^2 
put the equation all together you get v=sqrt(FrgM)/gM

Your parents are renting an apartment for you when you go away to college. An annual contract is $502.00/month with a 2-month pe
Vikentia [17]

Answer:

<em>The month-to-month contract will cost an extra $1356.</em>

Step-by-step explanation:

"An annual contract is $502.00/month with a 2-month penalty if you break the lease."

If you stay the whole year, and you pay $502 per month, you pay 12 * $502 = $6024 for the entire year.

"The month-to-month contract is $615.00/month."

If you stay the entire year, you pay 12 * $615 = $7380.

The difference is $7380 - $6024 = $1356

Help please, find the blanks
Aleks [24]

Answer:

OQ = 16

PR = 32

m<QRS = 90 degrees

Step-by-step explanation:

Since we know that PQRS is a rectangle, we can use its properties to find that:

OQ, OS, OR, and OP are equivalent, meaning that they all equal 16. Therefore, OQ = 16.

PR = OR + OP, meaning that 16 + 16 = PR, meaning that PR = 32.

And finally, m<QRS = 90 degrees because all corner angles in a rectangle are right angles.

I hope this helps!

a trapezoid with base measure of 23 km and 29km an area of 390km . find the height of the trapezoid.
cupoosta [38]
Hello!

To find the area of a trapezoid you use the equation

A =  \frac{a+b}{2} h

Put in the values you know

390 =  \frac{23+29}{2} h

Add

390 = \frac{52}{2} h

Divide

390 = 26 * h

Divide both sides by 26

15 = h

The answer is 15km

Hope this helps!
