Answer:
The linear speed is
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to
we have
substitute
step 2
Find the linear speed in feet per minute
we know that
The wheel is rotating at 10 revolutions per minute
Convert revolutions to feet
Remember that
One revolution is equal to the circumference of the circle
so
10 revolutions is equal to
therefore
The linear speed is

Answer:
w² + 5w = Area
Step-by-step explanation:
The equation for an area of a rectangle is:
Length x Width = area
If w is the width, and length is 5 units longer than the width, then length can be classed as w + 5
Simply multiply these two values to find the area:
w + (w + 5) =
(w * w) + (w * 5)
w² + 5w = area
This is the area formula as no area has been given, nor can this be simplified.

Answer:
C 2.0
Step-by-step explanation:
x-1.4 =0.6
add 1.4 to both sides
x=2.0
Answer:
here we work with factorials, so if we have a whole number N, then:
N! = N*(N-1)*.....*2*1
then, for the given expressions we have:
1) 6! = 6*5*4*3*2*1 = 720.
2) 3!*21 = (3*2*1)*21 = 216
3) and the last expression seems incomplete, i guess this is:
11! = 11*10*9*8*7*6*5*4*3*2*1 = 39,916,800
