Answer:
2.72 × 10^8 seconds
Step-by-step explanation:
1. Organize the given information to help you create the equation:
- Light travels 1.86 × 10^5 miles per 1 second
- Light travels 5.062 × 10^13 miles per <em>n</em> seconds
- Need to solve for <em>n</em>
2. Set up the equation (Make sure that both numerators and both denominators match units, so the seconds are either both on top or both on bottom, NOT switched):
= 
3. Cross multiply (Multiply the first fraction's numerator by the second's denominator, and vice versa. It doesn't matter what number is on which side of the = sign)
<em>n </em>× (1.86 × 10^5) = 5.062 × 10^13
4. Solve for <em>n</em> by isolating the variable and dividing.
= 
<em>n</em> =
<em>n </em>= 2.72 × 10^8 (Make sure to include the unit, seconds)
Answer:
Absolute value function.
Step-by-step explanation:
- The absolute value of a number helps us to calculate the distance between a number and zero, provided the direction does not play an important role.
- The absolute value of a number can never be negative since it is the value of distance.
- The absolute value function is defined as:
So, it is correct to write the statement that distance between 0 and 6 is equal to distance between 0 and -6.
Let us say that the number of pens that Matt has is x.
Therefore the number of pen that Sarah has is:
Sarah pens = (5/4) (1/3) x = (5/12) x
So the total number of pens they have is:
total = x + (5/12) x = (17/12) x
Hence the fraction of Matts pen is:
fraction = x / [(17/12) x]
fraction = 12/17
