Velocity * time = distance
40 (miles / hour) * t (hours) = 60 (miles)
Take note how the units work. miles/hour * hours = miles. This is an indication that a formula we picked is correct.
Now, looking at our formula (and neglecting units at this point)
40t = 60
t = 60/40
<span>t = 1.5 hours</span>

the slope id going up at a rate of 3
Interior and exterior angle<span> formulas: The </span>sum of the measures<span> of the interior </span>angles<span>of a </span>polygon<span> with n sides is (n – 2)180. The </span>measure<span> of each interior </span>angle<span> of an equiangular n-gon is. If you count one </span>exterior angle<span> at each vertex, the </span>sum of the measures of the exterior angles<span> of a </span>polygon<span> is always 360°. Hope this helps ^^</span>
Answer:
B. (6√2 + 12) inches
Step-by-step explanation:
The length of the kite edge at upper left is ...
x/sin(45°) = x/(1/√2) = x√2
The length of the kite edge at upper right is ...
x/sin(30°) = x/(1/2) = 2x
The perimeter of the kite is double the sum of the lengths of these edges:
P = 2(x√2 +2x) = 2x(√2 +2)
For x=3 in, this is ...
P = 2·(3 in)(√2 +2)
P = (6√2 +12) in
_____
The sine of an angle is the ratio of the side opposite to the hypotenuse. Here, the side opposite is x, and the hypotenuse is the kite edge of interest.
x/hypotenuse = sin(angle)
hypotenuse = x/sin(angle) . . . . . solve for hypotenuse
