A magic carpet is made with three different colors of yarn. The ratio of each color is shown below. 10 parts gold yarn, 7 parts

serious [3.7K]

Answer: 22.5 yards

Step-by-step explanation:

There are a total of 20 parts yarn. This means that 3/20 of the carpet is silver. So in order to compare this to the 150 meters of total yarn, you would set up this equation:

3/20 = x/150

Next, you cross multiply:

3*150 = 20*x or simplified would be 450 = 20x

Next, you divide both sides by 20 to get x by itself.

450/20 = 22.5, so x is equal to 22.5

This means you have 22.5 yards of silver in the carpet.

A particle decays at a rate of 0.45% annually. assume and initial amount of 300 mg. (

raketka [301]

The increase is an exponential increase in a multiplier
$100%+0.45%=100.45%$ and as decimal 1.0045

Final Value = Initial Value × $multiplier^{number of years}$
Final value = $300(1.0045)^{60}$
Final value = 393 mg (to the nearest whole number)

Half life = 0.5 years
Final value = $300(1.0045)^{0.5}$ =301 mg
