Find the area of a circle that has a circumference of 12π in.

Answers

Answer 1

Answer:

a = 1.91

Step-by-step explanation:

12 = 2π(r)

12/2 = 2π(r)/2

dividing by 2

=

6 = π(r)

you then divide this by π, or 3.14

6/3.14 = π(r)/3.14

=

1.91

Step-by-step explanation:

dy/dx=2xy/x²+y² solve​

Answers

Answer:

[tex]y=\frac{-1}{2} \sqrt[]{4x^2+4c_{1}^2} -c_{1}\ or \ \frac{1}{2} \sqrt[]{4x^2+4c_{1}^2} -c_{1}[/tex]

Step-by-step explanation:

As it is first order nonlinear ordinary differential equation

Let y(x) = x v(x)

2xy/(x²+y²)=2v/(v^2+1)

dy=xdv+vdx

dy/dx=d(dv/dx)+v

x(dv/dx)+v=(2v)/(v^2+1)

dv/dx=[(2v)/(v^2+1)-v]/x

[tex]\frac{dv}{dx}=\frac{-(v^2-1)v}{x(v^2+1)}[/tex]

[tex]\frac{v^2+1}{(v^2-1)v}dv=\frac{-1}{x}dx[/tex]

∫[tex]\frac{v^2+1}{(v^2-1)v}dv[/tex] = ∫[tex]\frac{-1}{x}dx[/tex]

u=v^2

du=2vdv

Left hand side:

∫[tex]\frac{v^2+1}{v(v^2-1)}dv[/tex]

=∫[tex]\frac{u+1}{2u(u-1)}du[/tex]

=[tex]\frac{1}{2}[/tex]∫[tex](\frac{2}{u-1} -\frac{1}{u} )du[/tex]

=[tex]ln(u-1)-\frac{ln(u)}{2} +c[/tex]

=[tex]ln(v^2-1)-\frac{ln(v^2)}{2}+c[/tex]

Right hand side:

[tex]=-ln(x)[/tex]

Solve for v:

[tex]v=-\frac{-c_{1}+\sqrt{c_{2}+4x^2 } }{2x} \ or \ \frac{-c_{1}+\sqrt{c_{2}+4x^2 } }{2x}\\[/tex]

[tex]y=\frac{-1}{2} \sqrt[]{4x^2+4c_{1}^2} -c_{1}\ or \ \frac{1}{2} \sqrt[]{4x^2+4c_{1}^2} -c_{1}[/tex]

Juhi sells a washing machine for Rs 13500. She loses 20% in the bargain . What was the price at which she bought it

Answers

Required Answer :-

Concept :

➽ Let the cost price of the washing machine be a variable and apply the condition that the loss Juhi faced was 20% of the cost price, i.e., Rs. 13,500 is 80% of the cost price to form an equation. Solve the equation to get the answer.

Solution :

➽ The selling price of the washing machine after bargain = Rs 13, 500

➽ percentage of loss she had in the bargain = 20 %

let the price paid by juhi be x

➽ Now interpreting the statement in the question

in mathematical form we get :

[tex] \implies[/tex] loss = Rs 2 / 10 × 2

[tex] \implies[/tex] Loss = Rs 2 / 10 × x

➽ According to the simple marketing norm, if we subtract the loss from the buying price, we will be getting the selling price for which Juhi sold the washing machine.

Profit / loss = purchasing price - Selling price

Substituting the values the above equation, we get;

[tex] \implies[/tex] 2 x / 10 = x - 13500

[tex] \implies[/tex] 2 x / 10 = x - 13500 / 2

On cross-multiplication, we get;

2 x = 10 ( x - 13500 )

[tex] \implies[/tex] 2 x = 10 x - 13500

[tex] \implies[/tex] 8 x = 13500

∴ x = 13500 / 8 = 16875

∴ Hence the price that Juhi paid for buying the Washing machine was Rs. 16,875.

Additional information :

❑ Don’t get confused and take the 20% of the selling price while you solve, as you should be very clear that the percentage loss or profit are terms related to the actual pricing not to the price for which you crack the deal. The other way of thinking of this is that the selling price might vary from buyer to buyer depending on the bargain they put in, but the percentage should be defined from a fixed mark so that you can easily handle it. The reason that most products in the market have an MRP tag on it making it easier for all the sellers to handle their margins.

We need a rock garden with a perimeter of 12 feet and an area of 8 square feet


Length: Feet
Width: Feet​

Answers

Answer:

Length: 4 feet

Width: 2 feet

Step-by-step explanation:

The only possibilities that could get an area of 8 feet are 4 x 2 and 8 x 1

However, it has to be 4 x 2 because the 8 x 1 dimension won't have a perimeter of 12 feet.

The dimensions of 4 x 2 will have an area of 8 square feet, since 4(2) = 8

It will also have a perimeter of 12 feet because 4 + 4 + 2 + 2 = 12

So, the length is 4 feet and the width is 2 feet

semesters, she had 96 credits.
Which of these expresses the rate at which she is earning credits?

Answer:

x = 14

Step-by-step explanation:

Credits = 12  Semesters = 6   Total Credits = 96

6x = 84

Divide 6x = 84 by 6.

x = 14

Answers

Answer:

[tex]C =\frac{5}{9}(F - 32)[/tex]

Step-by-step explanation:

Given

[tex]F = 1.8C + 32[/tex]

Required

Solve for C

[tex]F = 1.8C + 32[/tex]

Subtract 32 from both sides

[tex]F-32 = 1.8C + 32-32[/tex]

[tex]F-32 = 1.8C[/tex]

Divide both sides by 1.8

[tex]\frac{1}{1.8}(F - 32) = C[/tex]

Express the decimal as fraction

[tex]\frac{1}{18/10}(F - 32) = C[/tex]

[tex]\frac{10}{18}(F - 32) = C[/tex]

Simplify

Step-by-step explanation:

First Case:

5+4=8

No this is not correct as when 5 is added to 4 then the result should be - (1+1+1+1+1) + (1+1+1+1)

= 1 + 1 + 1 + 1 + 1 + 1 + 1 +1 +1

= 9

So this is not correct.

Second Case:

1 + 1 = 2

Yes this is correct when 1 and 1 are added for two times it results in 2.
