Answer:

94.2 inches.

Step-by-step explanation:

First, I just want to clarify that \pi is actually spelled pi, not pie, like the pie you eat.

Finding the circumference is pretty easy. It is just the diameter times pi.

So if the diameter is 30 inches, and we use 3.14 for pi, then the circumference of the sign would be 94.2 inches.

Hope this helps!

The number 2400 is first increased by 30%.The value obtained is next decreased by 20%.Find the final number
kvasek [131]

<em>2400 is increased by 30%.</em>

so,

2400 + (30/100 * 2400)

2400 + (30 * 24)

2400 + 720

3120

<em>this number is decreased by 20%.</em>

so,

3120 - (20/100 * 3120)

3120 - (2 * 312)

3120 - 624

2496

therefore, the final number will be 2496.

2x^2 - 7x - 6 = 0

x1 = \frac{- b  +  \sqrt{ {b}^{2} - 4ac }}{2a}
x2 = \frac{- b   -   \sqrt{ {b}^{2} - 4ac }}{2a}
where a=2
where b=-7
where c=-6

solve for x1 and x2

x1=4.21
x2=-0.71

Answer:

<em>It has infinitely as many solutions</em>

Step-by-step explanation:

Equations and Identities

When dealing with equations, we must find values of the variable who mak the expression become an identity.

The expression is an identity regardless on what the value of x is, so we can say the equation has infinite as many solutions. For example x=0 will make the expression look like 3=3 which is an identity. If x=8, we'll obtain 27=27 and so on
