4 hours = 4×60
= 240 minutes
240÷12
= 20 songs
the correct answer is 20 songs
Answer:
x = 7
Step-by-step explanation:
The relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(30°) = x/14
x = 14·sin(30°) = 14·0.5 . . . . . multiply by 14 and evaluate
x = 7

<em>Additional comment</em>
The triangle shown is a 30°-60°-90° triangle. The ratios of sides, shortest-to-longest, are ...
1 : √3 : 2
As we have seen here, the shortest side is 1/2 the length of the longest side, so x = 14/2 = 7.
This triangle and these ratios show up often, so it can be worthwhile to remember these ratios.
Answer:
Step-by-step explanation:
in y = mx + b form, the slope can be found in the m position
y = mx + b
y = 6x - 9......so ur slope, the number in the m position) is 6 <==
The answer will be 62.4. We know this because of the next procedure:
<span>We know that:
the volume of a cylinder is pi * r^2 * h
the volume of a cone is 1/3 * pi * r^2 * h
the total height is 47.
the height of the cone is 12.
</span><span>the height of the cylinder must be 35.
Now, if the top half is filled with sand, then the volume of the sand is
pi * 4^2 * 36 and the volume of the cone is 1/3 * pi * 4^2 * 12.
the total volume = 1960.353816 cubic millimeters.
since the top drains at the rate of 10 * pi cubic millimeters per second, the top will be empty and the bottom full after 1960.353816 / (10 * pi) = 62.4 seconds.
I hope this answer is ok for you </span>
The slope would be letter b
