The perimeter of rectangle is 40 cm and the breadth is 8 cm. Find its length.

Answers

Answer 1

Answer:

divide 40 by 8cm. it's pretty self explanatory

Step-by-step explanation:

[tex]40cm \div 8cm[/tex]

divided 8 on both sides.

divide 40 from 8 and you're left with 5 cm. the length is 5.

Answer 2

Answer:

length = 12 cm

Step-by-step explanation:

The perimeter (P) of a rectangle is calculated as

P = 2l + 2b ( l is the length and b the breadth )

let x be the length , then

2x + 2(8) = 40

2x + 16 = 40 ( subtract 16 from both sides )

2x = 24 ( divide both sides by 2 )

x = 12

That is the length is 12 cm

Answers

Answer:he eighth sweater costs $29

Step-by-step explanation:

Let the price of the eighth sweater be re[presented as X

We know that

Mean Price =Total sum of cost of sweater bought/ Number of sweater'

Plugging in our known values we have that  

40=$50+ $55+ $30+ $35+ $39+ $40 + $42+X  /8

8 X 40 =291 +X

320=291 +X

X =320-291

X=29

Therefore, the eighth sweater costs $29

Answers

Answer:

Part A     A.  400 sq ft.

Part B     A.   509 sq ft

Step-by-step explanation:

Part A

Area of square = side squared

Since all the sides of the square are congruent and the perimeter is 80, then the length of each side is 80/4 = 20

A = 20^2 = 400 sq ft

Part B

C = πd

80 =

80/π = d

r = d/2 = 80/2π = 40/π

A = πr^2 = π(40/π)^2

   = 1600π/π^2 = 1600/π = 1600/3.14 = 509 sq ft

Step-by-step explanation:

The distances are shown in the figure

[tex]\tan25^{\circ}=\dfrac{p}{b}\\\Rightarrow p=b\tan25^{\circ}[/tex]

[tex]\tan15^{\circ}=\dfrac{p}{b+100}\\\Rightarrow p=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b\tan25^{\circ}=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b=\dfrac{100\tan15^{\circ}}{\tan25^{\circ}-\tan15^{\circ}}\\\Rightarrow b=135.08\ \text{ft}[/tex]

[tex]p=b\tan25^{\circ}=135.08\times\tan25^{\circ}\\\Rightarrow p=62.99\approx 63\ \text{ft}[/tex]

Can someone help me with this problem 3(x+1)=11 I need it step by step

Answers

Answer:

x = 2.66666667

Step-by-step explanation:

3(x + 1) = 11

We multiply both x and 1 by 3 and get

3x + 3 = 11

Now we subtract 3 from both sides

3x + 3 - 3 = 11 - 3

3x = 8

Now divide both sides by 3

3x/3 = 8/3

x = 2.66666667

(っ◔◡◔)っ ♥ Hope It Helps ♥

3(x+1)=11
remove the parenthesis
3x+1=11
move the constant to the right side and change the sign
3x=11-3
subtract
3x=8
divide both sides by 3
