By definition, \pi is the ratio between the circumference and the diameter:

\pi=\dfrac{C}{d}

Which implies

d=\dfrac{C}{\pi}

So, your diameter is

d=\dfrac{307.72}{\pi}

Answer: 98 units

Step-by-step explanation: C=d x pi

Divide circumference by 3.14. You will get d=98

andrey2020 [161]
First, you have to make them into decimals to make it easier. 2/8 equals 0.25.
1/5 and 2/10 equal 0.2. 0.2+0.2+0.25 equals 0.65 so if you suppose Jon's money is 1 dollar, he has 35 cents left. In a fraction, 0.35 is 35/100. If you simplify 35/100, it's 7/20. 

Answer: Jon has 35/100 or 7/20 or his money left.

I hope it helps!

Solve for x: 5 over x equals 4 over quantity x plus 3<br><br> 5<br> 3<br> −3<br> −15
Firdavs [7]

Answer:

x = - 15

Step-by-step explanation:

The equation is  \frac{5}{x}=\frac{4}{x+3}

We now cross mulitply and do algebra to figure the value of x (shown below):

\frac{5}{x}=\frac{4}{x+3}\\5(x+3)=4(x)\\5x+15=4x\\5x-4x=-15\\x=-15

Hence x = -15

How do I factor the following equation in the link? It has been factored, but I need to know the steps.
Vlad [161]

Given

2x^2-x-3=0

How to factor

Solution

Step 1

Multiply the first and last costant

-3\times2x^2=-6x^2

Step 2

Write out all the pair factors of -6x^2

\begin{gathered} -6x^2=-6x\text{ and x} \\ -6x^2=-x\text{ and 6x} \\ -6x^2=\text{ -3x and 2x} \\ -6x^2=\text{ -2x and 3x} \end{gathered}

Step 3

Check for the pair, such that when you add you will get -x

\begin{gathered} it\text{ is } \\ -3x+2x=-x \\ \therefore-3x,\text{ 2x} \end{gathered}

Step 4

Replace -x with -3x+2x in the equation

2x^2-3x+2x-3=0

Step 5

Put them into brackets Since + is at the center no stress.

(2x^2-3x)+(2x-3)=0

Step 6

Factor out what is common in the bracket

x(2x^{}-3)+1(2x-3)=0

Step 7

What is in the bracket are the same, pick one

\therefore(2x-3)(x+1)=0_{}
