Answer:
n = 52m/6.5
Step-by-step explanation:
We are given that;
Distance run; d = 6.5 miles
Time;t = 52 minutes.
Thus, at rate per minute, is;
v = 6.5/52 miles/minutes
Now, we want to find number of minutes, n, she will take to
run m miles at this rate of 6.5/52.
Thus, m/n = 6.5/52
Cross multiply to give;
52m = 6.5n
n = 52m/6.5
Answer:
X = 60°
Step-by-step explanation:
the angle you are looking for is a corresponding angle to the angle given (121°)
2x + 1 = 121
121 - 1 = 2x
121 - 1 = 120
2x = 120
120/2 = 60
X = 60
The hurdle and runner form a right triangle (see attached picture) such that
sin(30°) = <em>h</em> / (5 ft)
and
cos(30°) = <em>x</em> / (5 ft)
where <em>h</em> is the height of the hurdle and <em>x</em> is the horizontal distance from where the runner jumps to the hurdle. So
<em>h</em> = (5 ft) sin(30°) = 5/2 ft = 2.5 ft
<em>x</em> = (5 ft) cos(30°) = (5√3)/2 ft ≈ 4.33 ft
You use the theorem you can apply to your problem.
If there is no tangent, the secant-tangent product theorem cannot apply.
If you don't have two secants, the secant-secant product theorem cannot apply.
