Answer: 5
Step-by-step explanation:
The question is asking how many tenths are in one half. You need to divide one half by one tenth. To divide fractions you need to invert and multiply.
1/2 ÷ 1/10
Step 1: Invert and multiply
1/2 × 10/1 = 10/2
Step 2: Simplify
10/2 = 5

Answer:
50 times
Step-by-step explanation:
You are going to flip a coin 100 times. There are 2 sides. So, what you would do is divide 100 by two because there are two sides. There is a 50% chance that the coin will land on heads, and a 50% chance it will land on tails.

1. (3,2)....because when finding the slope, we find the the slope of mn and the slope of op are negative reciprocals.
2. y = 5x - 7.....slope here is 5....perpendicular line has a negative reciprocal slope...so the slope has to be -1/5
y= mx + b
slope(m) = -1/5
(-10,3)...x = -10 and y = 3
now we sub and find b, the y int
3 = -1/5(-10) + b
3 = 2 + b
3 - 2= b
1 = b
so ur perpendicular equation is : y = -1/5x + 1
1 light-year = roughly 5,874,601,700,000 miles. (rounded)
To work it out, take the speed of light, and change units a few times:
(186,282.397 miles/second)
times
(86,400 second/day)
times
(365 day/year)
= (186,282.397 x 86,400 x 365) mile/year .
You can whip that out on your calculator in no time.
