To calculate unit rate, you are simply finding the unit ($) per rate (pound). Start by setting up a ratio, in this case, you have $7.96 per 5 pounds. You want to find the price per pound. Fractions are just another way to write a division problem, so divide.
$7.96/5 = approx. $1.59 per pound
Hope this helps!
Answer:
a=21.1
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.
It already tells you that he ran 100 meters so what you need to do is convert kilometer to meter and centimeter to meter.
1 kilometer is is 1000 meters. 1 meter is 100 centimeters.
So 5000 centimeters is 50 meters.
Add 100 + 50 + 1000 =
1,150 meters :)
Answer: A/B *100,000.
Step-by-step explanation: Since crude death rate is the number of deaths of persons in a particular area divided by the total population of that area at a particular time multiplied by 100,000.
Mathematical expression :
(Total persons death in 2009/
Total population in 2009) * 100000
If the question is, "What is the scale factor." That would be a scale (factor) of 2.
