<u>1. First find the density of your chain</u>
- Volume = displaced water volume
= Volume of Final level of water - initial level of water
= 20 ml - 15 ml = 5 ml
- Density = 66.7g / 5 ml = 13.34 g/ml
<u />
<u>2. Second, write the denisty of the chain as the weighted average of the densities of the other metals:</u>
Mass of gold × density of gold + mass of other metals × density of other metals, all divided by the mass of the chain.
Calling x the amount of gold, then the amount of other metals is 66.7 - x:



Then, there are 26.47 grams of gold in 66.7 grams of chain, which yields a percentage of:
- (26.47 / 66.7) × 100 = 39.7%
<span>The bisector of an angle is a ray whose end point is the vertex of the angle where it divides the angle into two smaller congruent angles. Therefore, it is in the interior of an angle and it shares a side.

Answer:
he's running 4/19 miles per minute or 12.6 miles per hour
Step-by-step explanation:
he is running 3 miles north, 4 miles east, and 5 miles southwest, a total of 12 miles
d = rt
12 = 57r
r = 12/57 or 4/19 (simplest form)
this is 4/19 miles per minute, multiply by 60 and it's about 12.6 miles per hour
Answer:
The slope is 5
