Koran is spending $12 on games and rides at another carnival, where a game costs $0.25 and a ride costs $1.

Vlad [161]

Answer:

$0.25x+y=12$

Step-by-step explanation:

Let

y ----> the number of rides

x ---> the number of games

we know that

The number of rides multiplied by $1 plus the number of games multiplied by $0.25 must be equal to $12 (the dollar amount Koran is spending)

The equation that represent this situation is

$0.25x+y=12$

Building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18 \pi18π18, pi m

Ksivusya [100]

the area A of the cross section of the column is $(81\pi )m^2$ .

Step-by-step explanation:

Here we have , building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18π, pi meters. We need to find What is the area A of the cross section of the column .Let's find out:

We know that , Circumference of circle = $2\pi r$

⇒ $Circumference = 2\pi r$

⇒ $18\pi= 2\pi r$

⇒ $\frac{18\pi}{2\pi }= \frac{2\pi r}{2\pi }$

⇒ $\frac{18\pi}{2\pi }=r$

⇒ $r=9$

We know that area of circle = $\pi r^2$

⇒ $Area= \pi r^2$

⇒ $Area= \pi 9^2$

⇒ $Area= 81\pi$

Therefore , the area A of the cross section of the column is $(81\pi )m^2$ .
