A can of tuna fish has a height 1inch and the diameter of 3inches how many square inches of paper are needed for the label? How many square inches of metal are needed to make the can including the top and bottom. Round your answer to the nearest whole number use 3. 14 for it

Answers

Answer 1

The square inches of metal needed for the can is approximately 9 × 3.14 = 28.26 square inches, rounded to 28 square inches.

To calculate the square inches of paper needed for the label of a can of tuna fish, the surface area of the can needs to be determined. The label would cover the entire lateral surface of the can, which is the curved part excluding the top and bottom. The surface area of the lateral surface can be found using the formula for the lateral area of a cylinder: Lateral Area = 2πrh. For the square inches of metal needed to make the can, the total surface area including the top and bottom needs to be calculated. The total surface area of the can is the sum of the lateral area and the areas of the top and bottom, given by the formula:

[tex]Total\_Surface\_Area = 2\pi rh + 2\pi r^2.[/tex]

Given that the height (h) of the can is 1 inch and the diameter (d) is 3 inches, we can calculate the radius (r) by dividing the diameter by 2, which gives us r = 3/2 = 1.5 inches.

To find the square inches of paper needed for the label, we calculate the lateral area using the formula:

[tex]Lateral\_Area = 2\pi rh = 2\pi (1.5)(1) = 3\pi square inches.[/tex]

To find the square inches of metal needed for the can, we calculate the total surface area using the formula:

[tex]Total\_Surface\_Area = 2\pi rh + 2\pi r^2 = 2\pi(1.5)(1) + 2\pi(1.5)^2 = 9\pi square inches.[/tex]

Since we are asked to round the answers to the nearest whole number and use π ≈ 3.14, the square inches of paper needed for the label is approximately 3 × 3.14 = 9.42 square inches, rounded to 9 square inches. The square inches of metal needed for the can is approximately 9 × 3.14 = 28.26 square inches, rounded to 28 square inches.

what form is the equation 12y=2x=24

Answers

Answer:

Step-by-step explanation:

Simplifying

12y + 2x = 24

Reorder the terms:

2x + 12y = 24

Solving

2x + 12y = 24

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12y' to each side of the equation.

2x + 12y + -12y = 24 + -12y

Combine like terms: 12y + -12y = 0

2x + 0 = 24 + -12y

2x = 24 + -12y

Divide each side by '2'.

x = 12 + -6y

Simplifying

x = 12 + -6y

students in it as did the buses. Find the number of students in each van

Van: 46, Bus: 10

Answers

Answer: Van: 10, Bus: 46

Step-by-step explanation:

Let the number of students in each van be represented by v.

Let the number of students in each bus be represented by b.

The question given can be formed into an equation as:

3v + 13b = 628 ...... i

9v + 2b = 182 ......... ii

Multply equation i by 9

Multiply equation ii by 3

27v + 117b = 5652 ........ iii

27v + 6b = 546 ....... iv

Subtract iv from iii

111b = 5106

b = 5106/111

b = 46

Bus = 46

Recall that 9v + 2b = 182

9v + 2(46) = 182

9v + 92 = 182

9v = 182 - 92

9v = 90

v = 90/9

v = 10

Van = 10
