astraxan [27]

Answer:

$5.03\frac{rad}{sec}$

Step-by-step explanation:

To find the angular velocity divide the revolutions by the time

$\frac{16}{20}=0.8\frac{rev}{sec}$

Remember that

$1\ rev=2\pi \ rad$

Convert rev/sec to rad/sec

$0.8\frac{rev}{sec}=0.8*(2\pi)=1.6 \pi\frac{rad}{sec}$

assume $\pi=3.1416$

$1.6(3.1416)=5.03\frac{rad}{sec}$

Tcecarenko [31]

Answer:

The number of pounds of City Roast Columbian coffee they should buy is 1 and the number of pounds of French Roast Columbian coffee they should buy is 11.

Step-by-step explanation:

Let

x ----> the number of pounds of a City Roast Columbian coffee

y ---> the number of pounds of a French Roast Columbian coffee

we know that

$x+y=12$ -----> equation A

$7x+8.20y=8.10(12)$ ----> equation B

Solve the system of equations by graphing

The solution is the intersection point both graphs

The solution is the point (1,11)

therefore

The number of pounds of City Roast Columbian coffee they should buy is 1 and the number of pounds of French Roast Columbian coffee they should buy is 11.
