You going on a trip to Europe you need to figure out how much money you should save for gasoline you have determined that while you are traveling in Europe you will cover about 325 miles how many kilometers will you be traveling?

Answers

Answer:

523.035 km

Explanation:

It is given that, a distance of 325 miles is covered on a trip to Europe. In this problem, we need to find how many kilometers will you be traveling.

To convert 325 miles to km, we must know the conversion from miles to kilometers.

1 mile = 1.60934 km

For 325 miles, multiply it by 1.60934 i.e.

325 miles = (325 × 1.60934) km

= 523.035 km

Hence, you will be travelling 523.035 km on a trip to Europe.

Final answer:

To convert from miles to kilometers, you multiply the miles by 1.60934. Therefore, if you're planning to travel 325 miles in Europe, this is approximately equivalent to 523.0 kilometers.

Explanation:

When converting miles to kilometers, you should know that 1 mile is approximately equivalent to 1.60934 kilometers. To find out how many kilometers you will be traveling, you would multiply the total miles you are planning to travel by the conversion factor.

Therefore, if you plan to travel 325 miles:
325 miles * 1.60934 (kilometers/mile)= 523.0285 kilometers.

The answer can be rounded to the nearest tenth, therefore you will be traveling approximately 523.0 kilometers.

The Isotope calcium-41 decays Into potassium-41, with a half-life of 1.03 x 105 years. There is a sample of calcium-41 containing 5 x 10⁹ atoms.How many atoms of calcium-41 and potassium-41 will there be after 4.12 x 105 years?
OA 3.125 x 108 atoms of calcium-41 and 4.375 x 10⁹ atoms of potassium-41
OB. 6.25 x 108 atoms of calcium-41 and 4.6875 x 10° atoms of potassium-41
OC. 6.25 x 108 atoms of calcium-41 and 4.375 x 109 atoms of potassium-41
OD. 3.125 x 108 atoms of calcium-41 and 4.6875 x 10° atoms of potassium-41

Answers

The correct answer for this question will be option D.

Calcium-41 = 3.12× $10^8$ atoms

Potassium-41 = 4.69× $10^9$ atoms

As stated in the question,

Half life of isotope of Ca-14 which decays into K-14 = 1.03 × $10^5$ years

Therefore, after 1.03 × $10^5$ years (1 half life)

Ca-41 will be 50%

and, K-41 will be 50%

After 2.06 × $10^5$ years (2 half lives)

Ca-41 will be 25%

K-41 will be 75%

After 3.09 × $10^5$ years (3 half lives)

Ca-41 will be 12.5%

K-41 will be 87.5%

After 4.12 × $10^5$ years (4 half lives)

Ca-41 will be 6.25%

K-41 will be 93.75%

After 4.12 × $10^5$ years,

Ca-41 = 6.25/100 × 5× $10^9$

= 3.12 × $10^8$ atoms

K-41 = 93.75/100 × 5× $10^9$

= 4.69 × $10^9$ atoms

Therefore, option D is correct.
