A bookmark is 9 centimeters tall and 2 centimeters wide what is its area

Answers

Answer:

length of book mark =9cm

breadth of bookmark=2cm

area of bookmark=length×breadth

=9cm×2cm

=18cm answer

Final answer:

The area of the bookmark is found by multiplying its length (9 cm) by its width (2 cm), giving a total of 18 square centimeters.

Explanation:

The area of a shape is calculated by multiplying the length by the width. In this case, the length of the bookmark is 9 centimeters and the width is 2 centimeters. So, the area of the bookmark will be 9 cm multiplied by 2 cm which equals to 18 square centimeters.

On a trip, the fare was 50¢ for each adult and 25¢ for each child. If 30 passengers paid $12.25, how many adults and children went?Is this the right way to set up the equation?
50x + 25(30 - x) = 1225

Answers

Fare for each adult = 0.50 dollars
Fare for each child = 0.25 dollars
Total number of passengers = 30
Total amount paid for the trip = 30 dollars
Lat us assume the number of adults = x
Then
The number of children = 30 - x
So
0.50x + 0.25(30 - x) = 12.25
50x + 25(30 - x) = 1225
This is the right way of setting up the equation and you have done it correctly.

25x + 50x = 30(1225) is the equation that wouldn't work

Step-by-step explanation:

Given,

Total passenger = 30

There can be only two cases,

Case 1 : Let x be the number of adults,

So, the number of children = 30 - x,

Since, the total fare is $12.25 or 1225¢ ( 1 dollar = 100 cents ) in which 50¢ is for each adult and 25¢ is for each child,

⇒ 50x + 25(30 - x) = 1225,

Case 2 : let x be the number of children,

So, the number of adult = 30 - x,

The equation would be,

⇒ 50(30 - x) + 25x = 1225

Hence, the equations that could not be used to solve the given problem is,

25x + 50x = 30(1225)

the base of a jewelry box is a square with a side length of 5 1/2 inches. the box is 2 inches high. what is the volume of the box?

Answers

The volume of the jewelrybox is 60 1/2 cubic inches.

The area of a square with a side length of 5 1/2 inches can be found by multiplying the length of one side by itself, giving:

Area = (5 1/2) × (5 1/2) = 30 1/4 square inches

The height of the box is 2 inches.

Therefore, the volume of the jewelry box can be found by multiplying the area of the base by the height of the box, giving:

Volume = Area x Height = (30 1/4) × 2 = 60 1/2 cubic inches

Thus, the volume of the jewelrybox is 60 1/2 cubic inches.

There are 680 raisins in 8 bags. If each bag has the same number of raisins, how many raisins are in 12 bags? 900 raisins 935 raisins 1,020 raisins 1,056 raisins

Answers

Answer:

Raisins in 12 bags are:

1,020

Step-by-step explanation:

There are 680 raisins in 8 bags.

Each bag has the same number of raisins.

⇒ Raisins in each bag=680/8

= 85

So, Raisins in 12 bags=12×85

=1,020

Hence, Raisins in 12 bags are:

1,020

So you do 680/8=85 raisins in each bag
Then you times 85*12=1020 and that the answer

A Norman window has the shape of a rectangle surmounted by a semicircle. If the perimeter of the window is 16 ft, express the area A of the window as a function of the width x of the window.

Answers

This answer uses NMF for which, if needed, the syntax can be found in my profile. Please ignore the LaTeX (the image), I cannot remove it/change it, and it is incorrect. The answer is: f(x)={π{{x}^{2}}/{4}+x(16-{πx}/{2}-x)}/{2}

Final answer:

The area A of a Norman window in terms of its width x can be expressed as the function A(x) = 8x - x²/2 - πx²/8, deriving this equation involves isolating variables from the given perimeter equation.

Explanation:

A Norman window has the shape of a rectangle topped with a semicircle. If we take x as the width of the window and y as the height of the rectangle, then the perimeter of the window is given by P = 2y + x + πx/2 = 16 (since the perimeter is the sum of the rectangle's two sides, the width, and half the circumference of a circle with diameter x).

From this equation, we can express y as a function of x: y = 8 - x/2 - πx/4.

Then, the area A of the window is the sum of the area of the rectangle and the area of the semicircle, which equals A = xy + πx²/8 = x(8 - x/2 - πx/4) + πx²/8 = 8x - x²/2 - πx²/4 + πx²/8.

Therefore, the area A of the window as a function of the width x of the window is A(x) = 8x - x²/2 - πx²/8.
