A restaurant is at 75 percent capacity with 120 patrons. How many people are in the restaurant when it is 100 percent capacity?

Goryan [66]

There would be 160 people.

(.75)=(120)
(.25)=(40) (Divide by 3)
(1)=(160) (Multiply by 4)

A mass suspended from a spring is raised a distance of 5 cm above its resting position. The mass is released at time t=0 and all

miskamm [114]

Rates of change are the change of a quantity over another.

The rate of change of the mass position at 2.1 seconds is -89.6 cm/ s

The given parameters are:

$\mathbf{A = |5|}$ -- the amplitude

$\mathbf{T = \frac 13}$ --- the period

The position of the mass is modeled by:

$\mathbf{y= Acos(wt)}$

Where:

$\mathbf{w = \frac{2\pi }{T}}$

So, we have:

$\mathbf{w = \frac{2\pi}{1/3}}$

$\mathbf{w = 6\pi }$

$\mathbf{y= Acos(wt)}$ becomes

$\mathbf{y = |5|cos(6\pi t)}$

$\mathbf{y = 5cos(6\pi t)}$

Differentiate

$\mathbf{y' = 5 \times -sin(6\pi t) \times (6\pi)}$

$\mathbf{y' = -30\pi sin(6\pi t) }$

When t = 2.1, we have:

$\mathbf{y' = -30\pi sin(6\pi \times 2.1) }$

$\mathbf{y' = -30\pi sin(12.6\pi) }$

$\mathbf{y' = -30\pi \times 0.9510}$

$\mathbf{y' = -89.6296}$

Approximate

$\mathbf{y' = -89.6}$

Hence, the rate of change of the mass position at 2.1 seconds is -89.6 cm/ s

Solve for h<br> SA = 2pir^2 + 2pirh

aivan3 [116]

SA = 2πr² + 2πrh

• Factorize right side

SA = 2πr(r² + h)

• Divide both sides by 2πr

SA/2πr = r² + h

• Move r² to left side

h = r² - (SA/2πr)

Two buildings have the same total height.One building has 8 floors with height (h).The other building has a ground floor of 16 f

zhuklara [117]

Answer:

The equation representing the heights of each floor is $8h= 6h+16$

Height of each floor is 8 feet.

Step-by-step explanation:

Let the height of each floor be h

Number of floors one building has = 8

Hence Total Height of the building can be calculated by multiplying height of each floor with Number of floors.

Framing in equation form we get.

Total Height of One building = $8h$

Also

Ground floor of other building = 16 ft

Number of floors = 6

Hence Total Height of the building can be calculated by multiplying height of each floor with Number of floors plus the height of ground floor.

Total Height of Other building = $6h+16$

Also Given:

Two buildings have the same total height.

Hence Total Height of One building = Total Height of Other building

$8h= 6h+16$

Hence The equation representing the heights of each floor is $8h= 6h+16$

Now Solving these equation we get:

$8h= 6h+16$

We will first subtract 6h on both side using Subtraction Property of equality we get;

$8h-6h=6h+16-6h\\2h=16\\$

Now Dividing 2 on both side using Division Property of equality we get;

$\frac{2h}{2}=\frac{16}{2}\\\\h=8\ ft$

Hence Height of each floor is 8 feet.
