Annual sales for a company are $155,000 and increases at a rate if 8% per year for 9 years

Answers

8% of 155,000 = 12,400
155,000 + 12,400 = 167,400

- this is the rate for one year, find 8% of 167,400 and use addition to add your answer to 167,400 find the cost of the 2nd year, keep doing this until you have reached 9 years

The value of annual sales in 9 years is  $309,845.72.

What is the value of annual sales in 9 years?

In order to determine the annual sales of the company in 9 years, the formula to be used is:

FV = P (1 + r)^n

Where:

FV = Future value P = Present value R = interest rate N = number of years

$155,000 x (1.08)^9 = $309,845.72

The square has a side length of 10 ft and the circle inside the square has a diameter of 10 ft find the approximate area of the shaded region use 3.14 as an estimation for

Answers

Answer:

[tex]Area = 21.5ft^2[/tex]

Step-by-step explanation:

See attachment

Given

Square:

[tex]Length = 10ft[/tex]

Circle:

[tex]Diameter = 10ft[/tex]

[tex]\pi = 3.14[/tex]

Required: Calculate the area of the shaded region

First, calculate the area of the square:

[tex]A_1 = Length^2[/tex]

[tex]A_1 = (10ft)^2[/tex]

[tex]A_1 = 100ft^2[/tex]

Next, the area of the circle.

[tex]A_2 =\pi * \frac{d^2}{4}[/tex]

[tex]A_2 =3.14 * \frac{10^2}{4}[/tex]

[tex]A_2 =3.14 * \frac{100}{4}[/tex]

[tex]A_2 =3.14 * 25[/tex]

[tex]A_2 =78.5ft^2[/tex]

The shaded region has the following area

[tex]Area = A_1 - A_2[/tex]

i.e. the difference between the area of the square and  the area of the circle

[tex]Area = 100ft^2 - 78.5ft^2[/tex]

[tex]Area = 21.5ft^2[/tex]

What could you do to the equation 100x + 300 = 500 to change it into x + 3 = 5?

Answers

Answer:

2+3=5

Step-by-step explanation:

100x + 300 = 500

100x = 500 - 300

100× = 200

100x/100 = 200/100

therefore ^x = 2

x + 3 = 5

2 + 3 = 5

The equation 100x+300=500 is equal to the equation x+3=5.

Given that,

The equation is 100x+300=500

We have to get the equation x+3=5 from the given equation.

What is the equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. In any mathematical equation, we have LHS = RHS (left hand side equals right hand side).

We can solve in 2 methods.

1st method,

Taking the equation

100x+300=500

Divide the equation by 100

100x/100+300/100=500/100

We get

x+3=5

2nd method,

Taking the equation

100x+300=500

Taking 300 to right side

100x=500-300

Subtracting the 500 and 300

100x=200

Taking 100 to right side

x=200/100

Dividing the 200 by 100

x=2

Now,

x+3=5

Taking x to right side

x=5-3

Subtracting 5 and 3

x=2

Therefore, the equation 100x+300=500 is equal to the equation x+3=5.

Two trains train a interim be weird total of 333 tons. Train hey is heavier than train B.The difference of their weight is 141 tons… What is the weight of each train??

Answers

Answer:

Weight of Train A = A = 237 tons

Weight of Train B = B = 96 tons

Step-by-step explanation:

Two trains train a and be weigh a total of 333 tons. Train A is heavier than train B.The difference of their weight is 141 tons… What is the weight of each train??

Let us represent:

Weight of Train A = A

Weight of Train B = B

Our system of Equations is given as:

A + B = 333 tons..... Equation 1

A - B = 141 tons....... Equation 2

We solve using Elimination method

We Add Equation 1 and 2 together to Eliminate B

Hence:

2A = 474 tons

A = 474 tons/2

A = 237 tons

Solving for B using Equation 1

A + B = 333 tons..... Equation 1

237 tons + B = 333 tons

B = 333 tons - 237 tons

B = 96 tons

Therefore:

Weight of Train A = A = 237 tons

Weight of Train B = B = 96 tons
