The point 6 cm away from the center travels in a circle of circumference 2π*(6 cm) = 12π cm, so that it covers this distance per revolution, 12π cm/1 rev.
So the disk has a linear speed of
(6000 rev/min) * (12π cm/rev) = 72,000π cm/min
which is equivalent to
(72,000π cm/min) * (1/100,000 km/cm) * (60 min/h)
or approximately 135.7 km/h.
Answer:
75%
Step-by-step explanation:
The right skewed data set means the data mostly lies in the right tail. There is majority of data present in the right tail of the data set. The mean, median and mod all are different for the rightly skewed data set.
Answer:
3*x + 3*8 = 42 simplified as 3x + 24 = 42
Step-by-step explanation:
The correct first step in solving the equation is to apply the distributive property. Order of operations states to perform operations in this order, PEMDAS, left to right. Some operations can be applied at the same time left to right through the equation such as multiplication and division as well as addition and subtraction. Since 3 is being multiplied into parenthesis, this needs to be applied first using the distributive property.
3(x+8)=42
3*x + 3*8 = 42
3x + 24 = 42
You can continue to solve using inverse operations.
3x = 18
x = 6
Looks like (0,1) and (2,4) are on the line.
(0,1) is the y intercept, b=1
The slope is m=(4 - 1)/(2 - 0) = 3/2
Answer: y = (3/2) x + 1
