A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
ω = 5 revolutions per minute. 1 minute = (1/60) hour.
= 5*2π radians / (1/60) hour = 600π radians per hour π = 3.14
= 600*3.14 = 1884 radians / hour
but radius, r = 10 feet, 5280 feet = 1 mile, 10 feet = (10/5280) mile
Linear velocity, v = ωr
v = 1884 radians / hour * (10/5280) mile
v ≈ 3.568 miles / hour

Given :
Base area of Ms. Jones decorative pyramid = 6 inches²
Height of the decorative pyramid = 15 inches
We know that :
Volume of the decorative pyramid :
Therefore, the volume of the decorative pyramid with Ms. Jones = 30 inches³
Answer:
-1
Step-by-step explanation:
h(t) = – t – 4
Let t = -3
h(-3) = – -3 – 4
= +3 -4
-1
Answer:
no, the two triangles are not necessarily congruent
Step-by-step explanation:
given: AB=CB, <A=<C
BD=DB cuz' common
so u get two sides and one angle equal, SSA
BUT in order for congruent, it must SAS where the angle is between the two equal sides.
so ABD n CBD are not necessarily congruent but they may be
Answer:
No
