Henry's uncle from Japan promised to give him 35 g of gold. The local jewelry exchange will buy gold for $1224 per ounce. How mu
galina1969 [7]

Answer:

$1530

Step-by-step explanation:

First of all, it is required to convert 35g of gold into ounce.

Since,

1 oz = 28 g

or, we can write,

1 g = \frac{1}{28} oz

Now, for 35 g of gold, we can write,

35 * 1 g = 35 * \frac{1}{28} oz\\35 g = 1.25 oz

Since, local jewelry will buy at $ 1224 per oz, and we have 1.25 oz of gold, so,

1.25 * 1244\\$1530

Find the center and radius of the circle. Show all work
Alona [7]

The center is (-1, -2) and the radius of the circle is 5.

<h3>What is the equation of a circle?</h3>

The circle equation formula refers to the equation of a circle which represents the center-radius form of the circle.

A circle can be represented as;

\rm (x-h)^2+(y-k)^2=r^2

Where; h and k are the center of the circle r is the radius of the circle.

The given equation of the circle is;

\rm (x+1)^2+(y+2)^2=25

Comparing both the equations;

\rm (x+1)^2+(y+2)^2=25\\\\\rm (x+1)^2+(y+2)^2=5^2\\\\h = -1\\\\k = -2\\\\r^2=5^2\\\\r=5

Hence, the center is (-1, -2) and the radius of the circle is 5.
