Answer:
168 hours
8,736 hours
Step-by-step explanation:
1)
<em>Determine how many hours are equal to 1 week. </em>
1 week = 7 days
1 day = 24 hours
1 week * (7 days)/(1 week) * (24 hours)/(1 day) = 168 hours
2)
<em>How many hours are in a year (52 weeks)?</em>
1 week = 168 hours
1 year * (52 weeks)/(1 year) * (168 hours)/(1 week) = 8,736 hours
Answer:
99 yards
Step-by-step explanation:
To find the perimeter of a rectangle, the equation is perimeter = 2(width) +2(height). When we plug the known variables into this equation, it is 364 = 166 + 2(height). Now all we have to do is isolate the variable like in any algebra equation, leaving us with our final answer of 99 = height.
