1. Karen has a square cartolina whose sides measure 60

cm each. She cuts the cartolina into two equal rectangles.

Find the perimeter of one piece of rectangle.

2. A rectangle has a length of 30 cm and a width smaller

by 5 cm. What is its perimeter?​

Answers

Answer 1

If Karen cut her square cardboard into two equal rectangles, the perimeter of those rectangles is 180cm. On the other hand, if the rectangle is 25 cm wide, the perimeter would be 110 cm.

What is the perimeter of a geometric figure?

The perimeter of a geometric figure is the measure of the length of all its sides. In this case, if Karen has a square of cardboard with a side of 60cm, it can be inferred that she would have two rectangles with a height of 30cm and a base of 60cm, so the perimeter would be:

30cm + 60cm + 30cm + 60cm = 180cm

On the other hand, if the rectangle has a base of 30cm and a height of 25cm, the perimeter would be:

25cm + 30cm + 25cm + 30cm = 110cm

Step-by-step explanation:

Benito and Tyler are painting opposite sides of the same fence. Tyler has already painted 19 ½ feet of his side of the fence when Benito starts painting. Part A: How long will it take for the two sides of the fence to have an equal number of feet painted? 80 minutes How many feet will be painted on Benito's side of the fence when the two sides have an equal number of feet painted? 45 feet Part B: Tyler claims that because he started painting first, he will finish painting his side of the fence before Benito finishes painting his side. Is this true? Explain. Part C: The painter who finishes first gets to rest while the other painter finishes. How long will the painter who finishes first get to rest? Explain.

Answers

Answer:

Part A: The time it will take for both of them to painted equal number of feet is 4.875 minutes

The number of feet Benito will have painted when the two sides have equal length is 73.125 feet

Part B: It is not true that Tyler will finish painting his side of the fence before Benito finishes painting his

Part C: Time to rest is 1.864 minutes

Step-by-step explanation:

The given information are;

The length of fence Tyler already painted when Benito started = 19 ¹/₂ feet

Benito paints 15 feet/minute

Tyler paints 11 feet/minute

Length of fence = 150 feet

Part A:

The time it will take for both of them to painted equal number of feet is given as follows;

11×t + 19.5 = 15×t

4×t = 19.5

t = 19.5/4= 4.875 minutes

The time it will take for both of them to painted equal number of feet = 4.875 minutes

The length Benito will have painted when the two sides have equal length = 15 × 4.875 = 73.125 feet

Part B: The time it will take Tyler to finish painting his side of the fence is given as follows;

11 × t + 19.5 = 150

t = (150 - 19.5)/11 ≈ 11.864 minutes

While the time it will take Benito to finish painting his side of the fence is given as follows;

15 × t  = 150

t = 150/15 ≈ 10 minutes

Therefore it is not true that Tyler will finish painting his side of the fence before Benito finishes painting his

Part C: Given that Benito finishes before Tyler, the length of time Benito gets to rest is given as follows;

Time to rest = Time Tyler takes to finish - Time Benito takes to finish

Time to rest = 11.864 - 10 = 1.864 minutes.

What is quadratic and not quadratic?

Answers

Answer:

Step-by-step explanation:

A quadratic equation must contain

an [tex]x^{2}[/tex] term

and must not contain terms with degrees higher than [tex]x^{2}[/tex].

A non/not quadratic equation doesn't have an [tex]x^{2}[/tex] term. It also features a term such as [tex]x^{3}[/tex] which isn't allowed in quadratic equations

Answer:

A quadratic equation contains a quadratic term (x²), as per the name. The quadratic term must be any variable squared. A non-quadratic equation is an equation that does not contain a quadratic term such as .

The format for a quadratic equation should look like so: ax² + bx + c = 0, in which a, b, and c are all real numbers and a cannot be equivalent to 0. An example of a quadratic could be: 5x² + (-3x) + 5 = 0.

An example of a non-quadratic equation could be: x³ - 81 = 0.

$6000

increases by 10% but you then take away 5% fron the 10 as it decreases by 5. meaning you have incresed by 5% and adding the 15% equals 20%. so the account increases by 20%. 20% of 5000 equals 1000. add the two together and you get 6000. so the account total now is $6000

The complete cost of purchasing an asset is known as the original cost.The whole costs associated with purchasing and using an asset are taken into account when calculating its initial cost.

Find original cost ?Subtract the asset's cost from its salvage value (what you anticipate it to be worth at the end of its useful life) to determine depreciation using the straight-line technique.The amount that can be depreciated, or the depreciable basis, is the outcome.Subtract this sum from the asset's useful life, which is measured in years. Revenue less costs equals profit.Markup is calculated as follows: markup = 100 * (revenue - cost) / cost.And finally, use revenue = cost + cost * markup / 100 if you need to know the selling price. The gross profit of a unit, which is its sales price less its cost to produce or acquire for resale, is divided by the unit's cost to determine the markup %.The markup percentage, which is computed as (12 - 8) / 8, is 50% for an item that costs the business $8 to produce but is priced at $12.

        Original cost  = $ 34.15 - $ 0.45/ 100

After how much time on long distance calls to the nearest minute, would the cost of plan A be equal to the cost of plan B?

Answers

Answer:

68.18min

Step-by-step explanation:

let the cost of plan A be Y1

and the cost of plan B be Y2

let the number of minutes for both plans be x

let us model the cost of plan A

Y1= 13+0.37x-------1

let us model the cost of plan B

Y2= 28+0.15x------2

when Y1=Y2, we can now solve for x which is in minutes

13+0.37x=28+0.15x

collect like terms

13-28=0.15x-0.37x

-15=-0.22x

divide both sides by -0.22

x=-15/-0.22

x=68.18min
