Don't know if it's right, but do let me know! use percentage to visualise your workings. :)
If there is a decimal, you usually round when graphing.
Let
x----> the length side of the hypotenuse
y----> the length side of the <span>unknown leg
we know that
x=2*y----> equation 1
applying the Pythagoras Theorem
x</span>²=y²+3²-----> equation 2
substitute equation 1 in equation 2
[2*y]²=y²+3²----> 4*y²-y²=9-----> 3*y²=9----> y²=3
y=√3 ft
x=2*y----> x=2*√3 ft
the answer is
<span>the lengths of the three sides are
</span>hypotenuse=2√3 ft
one leg=√3 ft
other leg=3 ft

a). The equation is
Balance in my account = 12.5 m + 100 .
The graph is a straight line with slope = 12.5 and y-intercept = 100.
'm' is the number of months after you start this savings plan.
b). The part of the Real Estate ad that tells us the cost of land on Mars is cut off.
However much 10 acres will cost, put that number into the equation where it
says "Balance in my account", and solve the equation for 'm'.
25).
a). It's easy to find four points. Just let 'n' be 3, 4, 5, and 6, and for each one,
use the formula to calculate what 'S' is. Yes, if you plot them, they'll all fall in
a straight line.
b). No. The value n = 3.5 does not make sense in the context of the problem.
We're talking about polygons with 'n' sides, and it's very hard to draw or imagine
a polygon with 3.5 sides.
0.12 x 2984 or 12 x 2984 divided by 100 so 12 x 2984 = 35808 divided by 100 = 358.08 aka $358. 08
