Answer:

Answer:

The value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95

Step-by-step explanation:

Cost of building 20 years ago = 12000000

We are given that the cost depreciated at 9% per year

Formula : N(t)=N_0(1-r)^t

Where N(t)= Population after t years

N_0=Initial population=12000000

r= rate of depreciation=0.09

t = 20 years

Substitute the values in the formula:

N(t)=N_0(1-r)^t\nN(t)=12000000(1-0.09)^(20)

N(t)=1819738.95

Hence the value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95

Hi

You need to start by multiply all terms by (x-2)(x+1) and cancel

x(x+1)(x-1)(x-2)=-1(x-2)(x+1)

2x²-2x+2=-x²+x+2

Now you need to subtract -x²+x+2

2x²-2x+2-(-x²+x+2)=-x²+x+2-(-x²+x+2)

3x²-3x=0

Now factorize

3x(x-1)=0

3x=0 or x-1=0

x= 0 or x=1

A total of 120,000 votes were cast for 2 opposing candidates, Garcia and Pérez. If Garcia won by a ratio of 5 to 3, what was the number of votes cast for Pérez?

Answers

Total votes = 120,000
Gracia won by a ratio of 5 : 3
so, total votes earned by Gracia = 5/8 * 120,000 = 75000


So, number of votes cast for Pérez = (120000 - 75000)

The length is 12 centimeters, and the width is 5.5 centimeters.

Answers

If 1 inch represents 0.5 centimeter, then 28 inches will represent 28 * 0.5 = 14 centimeters and 15 inches will represent 15 * 0.5 = 7.5 centimeters.

The actual dimensions of the phone is: the length is 14 centimeters and the width is 7.5 centimeters.

Answer:

D.

The length is 14 centimeters, and the width is 7.5 centimeters.

In order to solve the equation −3x + 6 = 5, the first step is to (1 point)add 6 to both sides
divide by 5 on both sides
subtract 6 from both sides
multiply by 5 on both sides

Answers

Answer:

Option (C) is correct.

To solve the given equation −3x + 6 = 5,the first step is to subtract 6 from both sides.

Step-by-step explanation:

Given : equation −3x + 6 = 5

We have to solve for  x in the equation −3x + 6 = 5.

Consider, the equation −3x + 6 = 5

First step:  Subtract 6 both side , we get

⇒ −3x + 6 - 6 = 5 - 6

⇒ −3x  = -1

Second step : Divide both side by -3 , we get,

x=(1)/(3)

Thus, option (C) is correct.

To solve the given equation −3x + 6 = 5,the first step is to subtract 6 from both sides

   −3x + 6 = 5  | -6   (first step is: "subtract 6 from both sides" )

-3x = 5-6
-3x = -1      |  /(-3)   (second step is: "divide by (-3) on both sides)


\displaystyle \n x = (-1)/(-3) = \boxed{(1)/(3) }
