The approximate areas of two states are listed below.

Texas: 2.69×10^5 square miles

Determine the difference, in square miles, between the area of Texas and the area of Rhode Island. Write your answer in scientific notation.

Answer: _________________ square miles

Answers

Answer:

2.6779*10^5

Step-by-step explanation:

2.69 * 10^5 - 1.21 * 10^3

This is 2.6779*10^5 :)

The difference between the areas of Texas and the area of Rhode Island is given by equation A = 2.6779 x 10⁵ miles²

What is an 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.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the area of Texas be p = 2.69 x 10⁵ miles²

Let the area of Rhode Island be q = 1.21 x 10³ miles

Now , the difference of areas A = p - q

On simplifying the equation , we get

The difference between the area of Texas and the area of Rhode Island A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles

A = 2.69 x 10⁵ miles² - 1.21 x 10³ miles

A = 10³ ( 2.69 x 100 - 1.21 )

On further simplification , we get

A = 10³ ( 269 - 1.21 )

A = 267.79 x 10³

A = 2.6779 x 10⁵ miles²

Hence , the difference in areas is 2.6779 x 10⁵ miles²

Part B: Sales tax for all 3 retailers is 7.5%. What is the cost to purchase the cheapest coffeepot? (Round your answer to the nearest cent.)

Answers

Answer:

American Discounters is the cheapest.

Step-by-step explanation:

American Discounters:

149.49 - 30%

149.49 - (149.49 * 0.3) = 44.847

149.49 - 44.847 = 104.643

The Coffee Hut:

91.99 + 15%

91.99 + 13.8 = 105.79

The Bean:

Yall plzz helpp I dont want to fail math "what is the longest walking stick that can be placed in the bottom of a truck of length 80 cm and width 60cm"

Answers

Given:

Length of the truck = 80 cm

Width of the truck = 60 cm

To find:

The longest walking stick that can be placed in the bottom of a truck.

Solution:

The longest walking stick that can be placed in the bottom of a truck is the diagonal of the truck.

We know that, the diagonal of a rectangle is:

[tex]d=\sqrt{l^2+w^2}[/tex]

Where, l is the length and w is the width.

Putting [tex]l=80[/tex] and [tex]w=60[/tex], we get

[tex]d=\sqrt{(80)^2+(60)^2}[/tex]

[tex]d=\sqrt{6400+3600}[/tex]

[tex]d=\sqrt{10000}[/tex]

[tex]d=100[/tex]

Therefore, the length of the longest walking stick that can be placed in the bottom of a truck is 100 cm.

Nicholas has a map that shows a rectangular park with a circular pond. The scale of the map is 1.5 in: 8 yd. On a map, the width of the park is 2.5 inches and the length is 6.25 inches. The pond has a diameter of 2 inches. Find the actual area of the circular pond.Use the pi key. (Answer to the nearest tenth.)

Answers

Answer:

The actual area of the pond is 88.9 yd^2

Step-by-step explanation:

We know that in the map, 1.5 inches are equivalent to 8 yards in the real park.

We know that in the map, the pond has a diameter of 2 inches.

Now we want to find the actual area of the circular pond.

Then the first step is to find the diameter of the real pond.

We know that:

1.5 in = 8 yd.

Now we need to count how many times we have 1.5 inches in the diameter of the pond in the map, this is:

N = 2 in/ 1.5in = 1.33

Then the actual diameter of the pond is 1.33 times 8 yards, this is:

D = 1.33*8yd = 10.64 yd

Now, we know that for a circle of diameter d, the area is:

A = pi*(d/2)^2

where pi = 3.14

Then the area of the pond is:

A = 3.14*(10.64 yd/2)^2 = 88.9 yd^2

An airplane is flying diagonally across the state of Colorado. This state and its
dimensions are represented by the rectangle on the map shown.
Based on the measurements shown in the map, which measurement is closest to the
distance in miles the airplane will fly along the diagonal?

Answers

Answer:

C

Step-by-step explanation:

The measurement is closest to the distance in miles the airplane will fly along the diagonal is given by D = 476.1 miles

What is the diagonal of a rectangle?

The diagonal of a rectangle is calculated by the formula

From the Pythagoras Theorem , The hypotenuse² = base² + height² , and

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

Given data ,

Let the dimensions are represented by the rectangle be 280 mi x 385 mi

So , the length of the rectangular path L = 280 miles

The width of the rectangular path W = 385 miles

And , the distance in miles of airplane along the diagonal is given by

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

On simplifying , we get

The distance along the diagonal D = √ ( 280 )² + ( 385 )²

The distance along the diagonal D = √ ( 78400 + 148225 )

The distance along the diagonal D = √ ( 226625 )

The distance along the diagonal D = 476.1 miles

Hence , the distance is D = 476.1 miles
