Answer 1

Step-by-step explanation:

.05N + .10D = 1.65

.05 is the value of the nickel and .10 is the value of the dime.

N + D = 21 because you have some combination of them that total 21

solve for N: N = 21- D

substitute into the first equation

0.5 (21-D) + .10D = 1.65

1.05 - .05D + .10D = 1.65

.05D = .6

D = 12 you have 12 dimes

21-12 = 9 nickels

A record with a diameter of 12 inches rotates at 33 revolution per minute find the angular speed of the record in radians per second

Answers

9514 1404 393

Answer:

  1.1π radians/second

Step-by-step explanation:

Each revolution is 2π radians, and there are 60 seconds in a minute. The rotation rate is ...

  (33 rev/min)×(2π rad/rev)×(1 min)/(60 sec) = 66π/60 rad/sec

  = 1.1π rad/sec

The angular speed is 1.1π radians per second.

Answers

Answer:

[tex]Empty = \frac{5}{12}[/tex]

Step-by-step explanation:

Given

[tex]Water = \frac{1}{3}[/tex]

[tex]Oil = \frac{1}{4}[/tex]
