x = business man's salary
y = employee's salary
x + 10y = 64000
x = 6y
6y + 10y = 64000
16y = 64000
y = 64000/16 = 4000
x = 6*4000
x = 24000
business man's salary was $24,000
Maybe the money you owe someone
We use the <span>Pythagorean Theorem method.
</span><span><span>a^2 </span>+ <span>b^2 </span>= <span>c^2
</span></span>
9^2 + b^2 = 15^2
9^2 + 12^2 = 15^2
The length of side B is 12 cm
Count how much spaces from one point on the end of the line to the other.
Line VU has 9 units
Line VW has 12 units
Line UW has:
a² + b² = c²
9² + 12² = c²
81 + 144 = c²
c² = 225
√c² = √225
c = 15
Line UW has: 15 units
Now add all the units together to get the perimeter:
9 + 12 + 15 =
21 + 15 =
36
36 is your answer
hope this helps
