im sorry but did you ever get the answer?
The multiplier of each account's value is 1.05³ = 1.157625.
The $750 in the club's account will grow to
$750×1.157625 = 868.22
and each member will get 1/3 of that amount, $289.
The $250 in Sheri's individual account will grow to
$250×1.157625 = $289.
Sheri, Kayla, and Kayla's two friends will all have the same amount as a result of their investments.
The ground, the building, and the ladder form a right triangle, in which
the leaning ladder is the hypotenuse.
For the angle between the ladder and the ground, the 4-ft along the ground
is the side adjacent to the angle, and the 7-ft ladder is the hypotenuse.
(adjacent side) / (hypotenuse) = cosine of the angle.
Cosine(a) = 4/7 = 0.57143... (rounded)
Angle 'a' = <em>55.15 degrees</em> (rounded)
