Answer:

A motor running at 75 revolutions per second.

Step-by-step explanation:

Given statement: A motor running at 4500 RPM, revolutions per minute.

⇒ In one minute , a motor running at 4500 revolutions.

Use conversion:

1 min = 60 sec

We have to calculate how many revolutions per second.

in 60 sec , a motor running at 4500 revolutions

then,

in 1 sec , a motor running at \frac{4500}{60} = 75 revolutions.

Therefore, a motor running at 75 RPS, revolution per second.

Answer:

Motor run in 1 second = 75 revolution.

Step-by-step explanation:

Given  : A motor running at 4500 RPM, revolutions per minute,

To find : how many revolutions per second.

Solution : We have given

Motor run in minute = 4500 revolution.

1 minute = 60 second .

Then  ,

Motor run in 60 second  = 4500 revolution.

Motor run in 1 second = \frac{4500}{60} revolution.

Motor run in 1 second = \frac{450}{6} revolution.

Motor run in 1 second = 75 revolution.

Therefore, Motor run in 1 second = 75 revolution.

A monument in the shape of a right triangle sits on a rectangular pedestarl that is 7 meters high by 16 meters long. The longest
Minchanka [31]

Answer: 70 meters

Step-by-step explanation:

Hi, since the situation forms a right triangle and a rectangle, we have to apply the Pythagorean Theorem (for the triangle)

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (the longest side) and a and b are the other sides.  

Replacing with the values given:  

65^2 = 16^2 + x^2  

4,225 = 256 + x^2

4,225-256 = x^2

3,969=x^2

√3,969 =x

63=x

We have calculated the missing side of the triangle, now we have to add the height of the rectangle:

63 +7 =70 meters

Feel free to ask for more if needed or if you did not understand something.
