If the radius (r) is 36 inches, the circumference of the circle is C = 2pi r,
or C = 2pi(36 inches) = 72pi inches. Please note: that's pi, not pie.
Answer:
Step-by-step explanation:
Let h bet the height of the building.
Mark is 60+310 = 370 m from building.
35/60 = h/370
h = 1295/6 = 215⅚ meters
Answer:
will this work or help ?
Step-by-step explanation:
The given equation governs the height versus time of the object. h(0) = 64, so the ground is considered at h = 0. The question is at what time is h = 0? So, set h = 0 and solve for t.
-16t^2 + 48t + 64 = 0
We can divide both sides of this equation by -16 for simpler numbers. We get
t^2 - 3t - 4 = 0
We can factor this equation:
(t - 4)(t + 1) = 0
So, t = 4 and t = -1 are solutions.
But, time must be positive, so t = -1 makes no sense, so we discard it. This leaves
t = 4 sec.
Answer: $141.75
Explanation:
8:00-> 12:00= 4 hours
12:45->17:30= 5.45 hours
4+5.45=9.45 hours
9.45 x 15 = 141.75
