Answer:
If you write a number as a fraction, that number's reciprocal is a fraction with the numerator and the denominator switched around. For example, the reciprocal of
4
5
is
5
4
. Some general rules to keep in mind:
-If the fraction has a
0
in the numerator, the reciprocal is undefined.
-If the fraction has a
0
in the denominator, the fraction itself is undefined. Thus it can't have a reciprocal.
-Any other fraction has exactly one reciprocal.
Finally, the reciprocal of a reciprocal is the original fraction. This means if you flip a fraction's numerator and denominator, and then flip them back, you get the number you started with.
Step-by-step explanation:
You can change the denominator to 10 which will get you to 55/10 + 4/10. You can add these two together to get 59/10
1) Speed is measured in distance units divided by time units, such as miles per hour. Here, you're given the number of miles traveled and the number of hours it takes, so you can figure tha average speed to be
... speed (or "rate of change") = distance/time = 165 mi/(3 h) = 55 mi/h
2) "speed at the moment" 1.5 hours into the flight means ...
... d. an instantaneous rate of change at 1.5
3) To keep their average speed on target, the dragons must travel at higher than their average speed for a while.
Answer:
$20,720
Step-by-step explanation:
$518,000 x 4% = $20,720
Freya begins started with 200 yards.
Freya then increased her distance by adding five yards a day for two days.
x = 200 + (n - 1)5.
<em>[x = The distance Freya sprints on day 21]</em>
x = 200 + (21 - 1)5
x = 200 + (20) 5 = 300 yards
