The speed, S, of a bicycle varies directly with the number of revolutions per minute, R, that the pedals turn and the number of teeth on the front gear, F, and inversely with the number of teeth on the back gear B.
ANSWERS
Cooling down, Lars pedals 56 rpms. Which equation shows his speed?
S=(56) (52)/ (13) (14)
Cooling down, the speed of the bicycle is
⇒ 16 mph.
Question is incomplete :
The speed, S, of a bicycle varies directly with the number of revolutions per minute, R, that the pedals turn and the number of teeth on the front gear, F, and inversely with the number of teeth on the back gear B.
Lars is racing at 24 miles per hour. His front gear has 52 teeth and a back gear has 14 teeth. He is pedaling 84 revolutions per minute. As he sprints for the finish line, he pedals 112 revolutions per minute. What is his speed?
Answer:
32 mph
Step-by-step explanation:
Speed α number of revolutions α number of teeth on front gear α 1/teeth on back gear
Speed = S ; number of revolutions = R ; Number of teeth on front gear = F ; Number of teeth in back gear = B
S = k(R * F) / B
k = proportionality constant ;
24 = k(84 * 52) / 14
24 * 14 = 4368k
k = 336/4368
k = 0.0769230
Speed at R = 112
S = k(R * F) / B
S = 0.0769230(112 * 52) / 14
S = 447.999552 / 14
S = 31.999968
S = 32 mph

Step-by-step explanation:
Tires are rotating at a rate of 32 revolutions per minute. Find the angular speed of the tires in radians per minute.
Answer:
201.1 radians per minute
Step-by-step explanation:
The formula for Angular speed of tires in radians per minute =
1 revolutions per minute = 2π rad/min
32 revolutions per minute = x
x = 32 revolutions per minutes × 2 π radians per minute
x = 201.06192983 radians per minute
Approximately
x = 201.1 radians per minute
Therefore, the angular speed of the tires in radians per minute is 201.1 radians per minute
The angular speed of the tires in radians per minute is 201 rad per minute.
Angular speed is the rate at which an object changes it angles, it is measured in radians in a given time.
To convert from rad per minute to rev per minute, we divide by 2π.
1 rad per min = 1/2π rev per min
32 revolutions per minute = (32 * 2π) radians per minute = 201 rad per minute.
The angular speed of the tires in radians per minute is 201 rad per minute.

A line has a slope of 2 and a y-intercept of 9, what is the equation of the line
Answer:
y=2x+9
Step-by-step explanation:
Slope intercept form is y=mx+b
m is the slope (2)
b is the y-intercept (9)
Plug the slope and intercept you were given in and you get the equation of the line in slope intercept form
y=2x+9

which of the following graphs represents the equation y -2 = 3x-1
Answer:
y=3x+1
Step-by-step explanation:
Which expression is equilvalent to 2(x+y)+4(x+y)+8(x-y)?
Answer:
14x-2y
Step-by-step explanation:
just break down the expression by combining like terms and getting rid of the parenthesis like so:
2(x+y)+4(x+y)+8(x-y)
i multiplied the number in front of each parenthesis with both numbers inside
ex: 2(x+y)
2x+2y
result:
2x+2y+4x+4y+8x-8y
next:
14x-2y
Answer:
14x -2y
Step-by-step explanation:
2( x + y ) + 4( x + y ) + 8( x - y )
First, do the distributive property ( multiply what is in the parenthesis by what is out of it)
2( x + y ) + 4( x + y ) + 8( x - y )
2 * x + 2 * y + 4( x + y ) + 8( x - y )
2x + 2y + 4( x + y ) + 8( x - y )
2x + 2y + 4 * x + 4 * y + 8( x - y )
2x + 2y + 4x + 4y + 8( x - y )
2x + 2y + 4x + 4y + 8 * x + 8 * -y
2x + 2y + 4x + 4y + 8x - 8y
Now combine like terms
14x -2y
And you cannot simplify it anymore

Which rule describes the composition of transformations that maps ΔABC to ΔA"B"C"?
90 degree rotation about point 0 composition reflection across the x-axis
Reflection across the x-axis composition 90 degree rotation about point 0
180 degree rotation about point 0 composition reflection across the x-axis
Reflection across the x-axis composition 180 degree rotation about point 0
Answer:
Option BStep-by-step explanation:
As per the graph the order of transformations is:
1. 90 degree anticlockwise rotation about origin
This maps ABC to A'B'C'2. Reflection across x-axis
This map A'B'C' to A''B''C''Correct option is B (transformations read and applied from right to left)

The point (5, -6) is reflected over the x-axis. The coordinates of reflected point are (_______).
Group of answer choices
(5, 6)
(-5, 6)
(-5, -6)
(5, -6)
The correct answer is (5,-7) Hope that helps!
Answer:
it would be (-5,6)
Step-by-step explanation:
since it is just reflected and not moving anywhere it would just be the same coordinates but flipped values. if its positive then when its reflected it would be negative.
