Calculate the breadth if the perimeter is 16cm and the length is 5cm​

Answers

Answer 1

Step-by-step explanation:

Given,

perimeter - 16cm

length - 5cm

find breadth,

perimeter of rectangle = l × b

16cm = 5 × b

b = 16/5

b = 3.2 cm

Answer 2

Step-by-step explanation:

Given

perimeter (P) = 16 cm

Length(L) = 5 cm

breadth (b) = ?

We know

P = 2 (L + b)

16 = 2 ( 5 + b)

16 = 10 + 2b

2b = 16 - 10

2b = 6

b = 6 / 2

b = 3 cm

Hope it will help :)❤

If one inch represents 3 units, what dimensions would you use to draw a rectangular field that is 20 units by 14 units?​

Answers

Answer:

Step-by-step explanation:

If 1 inch = 3 units,

Therefore 1 unit = ⅓ inches, so to answer your question we have to

Multiply it by 20, to have :

20 units = 20× ⅓ = 20÷3

20 units = 6.66

Therefore we can use the same principle in that of 14 units.

14 units = (14 × ⅓) inches

14 units = 4.66 inches

A new gaming system costs $350. A store offers a 20% discount on the new gaming system. What is the amount of the discount?

Answers

Answer:

70

Step-by-step explanation:

Answer: $70

Step-by-step explanation:

1. Make an equation: since 100% price is equal to $350, you can make this ratio => 100:$350=80:$x

x stands for the cost after 20% discount.

2. Solve by cross multiply: 350*80=100x => 28000=100x => x=280

3. Subtract : to find the amount of discount, subtract the discounted price from the original price => 350-280=70

Orbet used 24 square tiles to make a rectangle. The perimeter of the rectangle is 20 units. What would be the perimeters of the other rectangles Corbet could make using only these 24 tiles? How do the areas of the rectangles compare? Explain.

Answers

Answer:

The perimeter of other rectangles are 50, 28, 22 units

The area of all possible rectangles are same and equals to 24 unit²

Step-by-step explanation:

Given - Orbet used 24 square tiles to make a rectangle. The perimeter of the rectangle is 20 units.

To find -  What would be the perimeters of the other rectangles Orbet could make using only these 24 tiles? How do the areas of the rectangles compare?

Proof -

We know that

Are of Rectangle = Length × Breadth

And Perimeter of Rectangle = 2 (Length + Breadth )

Now,

Given that,

Orbet used 24 square tiles

And perimeter of the rectangle made = 20

So,

Possible Length of rectangle = 6

Possible breadth of Rectangle = 4

Or Vice-versa.

Total number of Rectangles possible = 4

Possibilities are -  1 × 24, 2 × 12, 3 × 8, 4 × 6

Case I :

Length of rectangle = 1

Breadth of rectangle = 24

∴ Perimeter of rectangle = 2(1 + 24) = 2(25) = 50 units

Area of rectangle = 1 × 24 = 24 unit²

Case II :

Length of rectangle = 2

Breadth of rectangle = 12

∴ Perimeter of rectangle = 2(2 + 12) = 2(14) = 28 units

Area of rectangle = 2 × 12 = 24 unit²

Case III :

Length of rectangle = 3

Breadth of rectangle = 8

∴ Perimeter of rectangle = 2(3 + 8) = 2(11) = 22 units

Area of rectangle = 3 × 8 = 24 unit²

Case IV :

Length of rectangle = 4

Breadth of rectangle = 6

∴ Perimeter of rectangle = 2(4 + 6) = 2(10) = 20 units

Area of rectangle = 4 × 6 = 24 unit²

∴ we get

The perimeter of other rectangles are 50, 28, 22 units

The area of all possible rectangles are same and equals to 24 unit²

Is income salary? or is it the *take home pay* after tax deductions are made? and if it is the second one, then is income the same as *net monthly salary?*​

Answers

Yea salary typically makes up a persons income
Yes take home pay is after deductions. Usually differentiate by gross income and net income.

Net income would be the same as net monthly salary and take home pay.


Basically you get paid a salary and that that is gross income before deductions. Then money is taken out for taxes insurance retirement etc, and whatever is leftover is your take home pay or net income or net monthly salary whatever you wanna call it. Neto take home means after deductions
