Number of miles traveled by light in a light-year is 5.952 × 10^12 miles
Step-by-step explanation:
- Step 1: Find the number of miles (distance) in a light year by using the formula for speed = Distance/Time
⇒ Distance = Speed × Time
= 1.86 × 10^5 × 1 yr (convert to seconds)
= 1.86 × 10^5 × 365 days × 24 hrs × 60 mins × 60 sec
= 1.86 × 10^5 × 31,536 × 10³
= 1.86 × 3.2 × 10^5 × 10^7
= 5.952 × 10^12 miles
Answer:
The answer is 10
Step-by-step explanation:
a=10
Answer:
a
Step-by-step explanation:
The base angles PHJ and PJH are congruent , meaning ΔaPHJ is isosceles and so
HP = JP, thus
3x - 6 = x + 2 ( subtract x from both sides )
2x - 6 = 2 ( add 6 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Hence
HP = 3x - 6 = (3 × 4) - 6 = 12 - 6 = 6 → a
