Answer: 3,140 radians per minute.

Step-by-step explanation:

We know that the wheel does 500 revolutions per minute.

This is called the frequency of the wheel, and this is written as:

f = 500 rev/min = 500 RPM

The angular speed (or Angular velocity) is written as

ω = 2*pi*f

And this quantity is in radians/unit of time.

where pi = 3.14

then:

ω = 2*3.14*500 (rev/min)*(rad/rev) = 3,140 rad/min

This means that the angular velocity  (or angular speed) is 3,140 radians per minute.

Answer:

number of $20 bill = 4

Number of $5 bill = 5

Step-by-step explanation:

Given that:

Total number of $5 and $20 bills = 9

Let :

Number of $5 bills = x

Number of $20 bills = y

Combined worth of all bills = $105

x + y = 9 - - - (1)

5x + 20y = 105 - - - (2)

From (1)

x = 9 - y

Substitute x = 9 - y into (2)

5(9 - y) + 20y = 105

45 - 5y + 20y = 105

15y = 105 - 45

15y = 60

y = 60/15

y = 4

x = 9 - y

x = 9 - 4 = 5

Hence,

number of $20 bill = 4

Number of $5 bill = 5

Make perfect square <br> V^2 + 8v +
Yuri [45]
If you're asking for the final term, the solution is to take b(from ax^2+bx+c), half it, and then square it. So in this case, b is 8.
8/2=4
4^2=16
So:
v^2+8v+16
If you factor it, it becomes (v+4)^2, which shows that its a perfect square.

What is the total amount that Matthew's bank will receive after lending him $8,000 for four years at an interest rate of 6 perce
Goshia [24]

Given:

Matthew's bank lent him $8,000 for four years at an interest rate of 6 percent, compounded annually.

To Find:

The total amount that Matthew's bank will receive after 4 years.

Answer:

The total amount the bank will receive after 4 years is $10,099.8

Step-by-step explanation:

The principal amount 'P' lent to Matthew is $8000

The time period 't' is 4 years

The lending rate 'r' is 6%

As the interest is compounded annually, we use the Compound Interest formula to calculate the amount the bank will receive 'A' after 4 years.

The formula we use is

A=P(1+r)^t\\=8000(1+\frac{6}{100})^4\\\\=8000(\frac{106}{100})^4\\\\=8000(1.06)^4\\\\=10099.81

Thus, the total amount the bank will receive after 4 years is $10,099.8
