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:
10,300.77 cm³
Step-by-step explanation:
Radius = ½(diameter)
Diagonal:
sqrt[243 + 243]
sqrt(486)
Diameter
sqrt(486 + 243)
27
Radius: 27/2
Volume of sphere:
4/3 × pi × r³
4/3 × 3.14 × (27/2)³
10300.77 cm³
The answer is in the picture below. To get this answer you first plot the y-intercept which in this case is 9. Then after you plot the y-intercept plot the rest of the points by taking the slope, which is 4 and going up 4 over 1.
The unknown number . . . . . (z)
The sum of the unknown number and 22 . . . . . (z + 22)
The sum of the unknown number and 22
divided by the same unknown number . . . . . . . (z + 22) / z
You said that quotient is 12. (z + 22) / z = 12
Multiply each side by 'z' : (z + 22) = 12 z
Subtract 'z' from each side: 22 = 11 z
Divide each side by 11 : 2 = z .
