For this problem, let's use the approach of dimensional analysis. This technique is done by cancelling out like units that appear both on the numerator and the denominator side. As a result, this technique will let you know that your final answer conforms to what parameter is asked. In this case, the final answer should be in $. The solution is as follows:

$560/troy ounce * 1 troy ounce/480 grains * 1 grain/64.8 mg * 1000 mg/1 g * 1 g = $18

If f(x) = x2 − 1, and f(2a) = 35, then what could be the value of a ?
Naily [24]
<span>f(x)=<span>x2</span>−1</span>That means to find the value of the function at any value of x, we square x and subtract 1. If <span>x=2a</span>, we square <span>2a</span> and subtract 1:<span>f(2a)=(2a<span>)2</span>−1=4<span>a2</span>−1</span>Now, we know that <span>f(2a)=35</span>so we can find the value of a:<span>f(2a)=(2a<span>)2</span>−1=4<span>a2</span>−1=35</span><span>4<span>a2</span>−1+1=35+1</span><span>4<span>a2</span>=36</span><span><span>a2</span>=9</span><span><span>a=±3</span></span>

A raffle is being held to benefit the local animal shelter. They sell 717 tickets that do not win any prize, 19 tickets that win
matrenka [14]
Let’s start by finding the total amount of tickets sold

717+19+1=737

Now multiply by 5 to see how much money they initially brought in

737•5=3,685

Now let’s find the total expense of the prizes

166+(19•20)=t

166+380=546


Now subtract the expenses from the total ticket sales

3,685-546=3,139


They made $3,139 TOTAL


Now let’s divide the total made by the total tickets sold

3139 / 737 = 4.26


They made $4.26 PER TICKET


Hope this helps!

                  Find the circumference of the circle and show work. [refer to  

                  attachment]

\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

          Formula for Circumference of a Circle:-

        \dashrightarrow\star\bigstar\boxed{\boxed{C=2\pi r}}}

Where

  • C = circumference
  • π = pi (3.14…)
  • r = radius, which in this case is equal to 8

Substitute the value of r and solve:-

         C=2π(8)

        On simplification,

     

C=16π

On further simplification,

C=50.3

Therefore, we conclude that the circumference of this circle is

\dashrightarrow\star\bigstar\boxed{\boxed{\underline{\bold{C=50.3\:yd}}}}\bigstar\star\dashleftarrow

<h3>Good luck.</h3>
