106 divisible by 3 no
116 no
126 yes
136 no
146 no
156 yes
166 no
176 no
186 yes looks like every third one is divisible by 3 = 1/3
base1 = x base 2 = 7+x height = 6
area = (base1 + base2)/2 * 6 <====== red is median
60 = (x + 7/2 )*6
10 = median
median = (13/2 + 13/2+7 )/2 = 10
f = t = n five ten and twenty
5n + 10n + 20n = 560
35n = 560
n = twenty dollar coins = 16
x + x+ d + x + 2d + x + 3d = 360 x + 3d = 128 or x = 128 - 3d <======sub this into the equation
4 ( 128-3d) + 6d = 360
d = 25 1/3
x + 3d = 128
x = 128 -3d = 128 - 3 ( 25 1/3) = 52 degrees
Missing important info # of clams each borrowed and the interst rates each of them has to pay....
Right triangle with two equal legs (because the other two angles are each 45 degrees)
so AE = CE
pythag theorem
s^2 + s^2 = 1^2
2 s^2 = 1
s^2 = 1/2
s = AE =CE = sqrt (2) /2
Add 2x to both sides of the equation
Subtract 4 from both sides of the equation
then divide both sides of the equation by 7
Yeppers.....That's it !
From 1st base to 2nd base is a 60 ft leg of a right triangle
the hypotenuse would be from 2nd base to home plate
use pythagorean theorem d^2 = 60^2 + 60 ^2 d = from second to home = 84.85 ft You can finish, Yah?
x^2 -6x + k - 3 = 0
the two numbers added = -6 call them a and 2a a + 2a = -6
a = - 2
and a * 2a = k-3
2a^2 = k-3
8 = k-3
k = 11
