This is a triangle. The interior angles of a triangle always add up to 180 degrees. Thus, write an equation representing the sum of the given angles, with "180 degrees" on the right side.

4x-1 + 8x+2 + 71 = 180 degrees.

Solve for x!

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$

g100num [7]

Circumcerence = distance travelled in one full rotation = 2 x π x 8 = 16π

for 2 minutes and 15 seconds,
multiply 16π by 2.25 as 2 minutes is twice the distance of one rotation and 15 seconds is a quarter more

therefore answer is 36π = 113.1 inches
