area of large circle=452.16in²

area of small circle=pi×r²

area of small circle=3.14×8²

area pf small circle=200.96in²

area of shaded circle=452.16in²- 200.96in²

area of shaded circle =251.2in²

3. A restaurant bill of $350 was paid using $5 notes and $50 notes. The total number of
Sonbull [250]

The number of $5 notes is 10 and $50 notes is 6

Step-by-step explanation:

Let x be the number of $5 notes

and

y be the number of $50 notes

Then according to given statements

"The total number of notes used was 16."

x+y=16    Eqn 1

"A restaurant bill of $350 was paid using $5 notes and $50 notes."

5x+50y=350       Eqn 2

From\ Eqn\ 1\\x+y=16\\y=16-x\\Putting\ y=16-x\ in\ equation\ 2\\5x+50(16-x)=350\\5x+800-50x=350\\-45x+800=350\\Subtracting\ 800\ from\ both\ sides\\-45x+800-800=350-800\\-45x=-450\\Dividing\ both\ sides\ by\ -45\\\frac{-45x}{-45}=\frac{-450}{45}\\x=10

Putting x=10 in equation 1

10+y=16\\y=16-10\\y=6

So,

The number of $5 notes is 10 and $50 notes is 6

I need help knowing what x equals to ?. please help!!
ivanzaharov [21]
<h2>Hello!</h2>

The answer is: x=6

<h2>Why?</h2>

Since we don't have the function equation, but we have the graphic, we can use it to know what value of x makes the function equal to 0.

Finding what values of x does g(x)=0 means that we should find where the function intercepts the x-axis.

From the graphic, we can see that the functions intercepts the x-axis at x=6

Have a nice day!
