6 hours and 6 hours and 24 minutes
On the interval [-2π,2π], the x intercepts are:
-5π/4, -π/4, 3π/4, 7π/4
$141, this is because 235 divide by 10 is 23.5, multiply 23.5 by 6 and your answer is $141
<span>The question is tricky. But any way the longest side of a right triangle is always the hypotenuse. So we know the hypotenuse if 15 cm.
Now, consider the Pythagorean theorem:
a^2 + b^2 = h^2, where a and b are the sides of a right triangle and h is the hypotenuse.
We know one side is 12cm and the hypotenuse is 15 cm, so:
12^2 + b^2 = 15^2, or </span><span>1</span><span>44 + b^2 = 225
subtract 144 from either side to get
b^2 = 225 - 144 = 81
now take the square root of either side to get
b = 9
The third side is 9 cm</span>
Answer:
$425
Step-by-step explanation:
because the closest to 400$ is 425. hope this helps
