We can bring the ratios to a similar form, because 2:5 is the same as 4:10 (we can mupltiply rations by the same number)
so one ratio is 4:10 and the other is 4:15 and the difference is is 75 beads
in this ratio, we can see each number corresponding to a "unit" of beads: that means that what changed is that Patricia now has 5 more such groups (15-10=5), and since she has 75 beads more each unit must be 75/5=15.
so afterwards (and before) Karen had 4 such units, that is 60, and Patricia before had 10 such units, that is 150.
Euler's method is a procedure for solving differential equations with an initial value. The formula for Euler's method establishes the basic relationship between trig functions and complex exponential functions.
Euler's formula is:
In this case, r represents faces, v represents vertices and m is equal to edges, therefore, we have the following:
Answer:
323.11 ft
Step-by-step explanation:
The ellipse has two different axes which are the major and the minor axes. The major axis is longer than the minor axis. Therefore,
Major axis length = 2*a = 380; a = 380/2 = 190 ft
Minor axis length = 2*b = 200; b = 200/2 = 100 ft
To calculate the distance between Walter and Barbara (2*c), we consider the lengths a, b, and c as a right-angle triangle. If we use the Pythagoras theorem, we have:
c^2 = a^2 - b^2 = 190^2 - 100^2 = 26100
c = sqrt(26100) = 161.55 ft
Therefore, the distance between Walter and Barbara = 2*161.55 = 323.11 ft
