The ladder forms the hypotenuse of a right triangle. Solve for a
<span>a^2 + b^2 = c^2 </span>
<span>a^2 + 9^2 = 18^2 </span>
<span>a^2 + 81 = 324 </span>
<span>a^2 = 243 </span>
<span>a = 15.589 = 15.6 feet</span>
-3x - 4y = 2
<u>8y</u> = <u>-6x - 4</u>
8 8
y = -0.75x - 0.5
-3x - 4(-0.75x - 0.5) = 2
-3x + 3x + 2 = 2
0x + 2 = 2
<u> - 2 - 2</u>
<u>0x</u> = <u>0</u>
0 0
x = 0
-3(0) - 4y = 2
0 - 4y = 2
<u>- 0 - 0</u>
<u>-4y</u> = <u>2</u>
-4 -4
y = 0.5
(x, y) = (0, 0.5)
A earns $350×0.04×5 = $70 interest in interest over five years.
B earns $500×0.035×5 = $87.50 in interest over five years.
Do C the same way.
Answer:
7/10 of the socks are black and 2/10 of the socks are blue so 1/10 of the socks we dont know
