Step-by-step explanation:
Here, we want to apply the markup percentage so as to get the price of the jewelry
mathematically, we have the selling price as;
$22 + (30% of $22)

If the numbers that we are checking divisibility for are between 1-100, there are 3 numbers.
30, 60, and 90 are all divisible by both 3 and 10 because both 3 and 10 are factors of these 3 numbers.
Answer:
9.4m is the answer.
Step-by-step explanation:
a = 8m
b = 5m
c = ?
According to the Pythagoras theorem,
a² + b² = c²
8² + 5² = c²
64 + 25 = c²
89 = c²
c = 9.433
Rounding off,
c = 9.4m
Let p and w represent the speed of the plane and the speed of the wind, respectively.
.. speed = distance/time
.. p +w = 720/3 = 240
.. p -w = 720/4 = 180
Add the two equations to eliminate w.
.. 2p = 420
.. p = 210
.. w = p -180 = 30
The speed of the wind is 30 mph.
The speed of the plane in still air is 210 mph.
Answer:
9.07 and 7.77 respectively.
Step-by-step explanation:
To determine the upper control limit, add 0.65 lb to 8.42 lb, obtaining 9.07 lb.
To determine the lower one, subtract 0.65 lb from 8.42 lb, obtaining 7.77 lb.
