40/.10
okay so plan 1 is 20$ a month plus .10 cent each message
plan 2 40$ unlimited text.
now 20 is half of forty , so another 20 to get to 40
20/.10 gives you 200 messages until you reach the 40 dollar mark.
Answer:
4 feet
Step-by-step explanation:
Since the whispering gallery is 15 feet high and 60 feet wide, it forms an ellipse with major axis along the width of the gallery and minor axis along the height of the gallery.
Using the equation of an ellipse with major axis along the x-axis, we have
x²/a² + y²/b² = 1 where a = midpoint of the width = 60/2 = 30 feet and b = 15 feet.
c² = a² - b² where c = focus of the ellipse.
So, c² = a² - b²
= 30² - 15²
= 900 - 225
= 675
c = ±√675 = ±25.98 feet
So, the coordinate of the focus is thus (0, ±c) = (0, ±25.98) and the coordinate of the vertex is (0, ±a) = (0, ±30)
So, the distance between the foci and the vertex is the distance from the wall at which each of them should be positioned at the foci.
So, d = a - c
= 30 ft - 25.98 ft
= 4.02 feet
≅ 4 feet
Answer:
7.35 miles per hour
Step-by-step explanation:
Divide 29.4 by 4
Look to the last number in the decimal; the 5 is in the thousandths place. This means we put the given decimal number 185 over 1000.
Example: If you were given 0.52, it would be converted to 52/100 (the last digit is in the hundredths place so the decimal numbers 52 are placed over 100) and then simplified.
0.185 = 185/1000
= 185/1000
simplify by 5
= 37/200
ANSWER: 37/200 is the fraction conversion of 0.185
Hope this helps! :)
