So basically a decimal is moved based on how many zeros are in the dividing number
Ex. 51,000/100
because there are 2 zeros in the number one hundred, the decimal in 51,000 gets moved 2 places to the left
So it goes from 51,000 to 510
Ex. 16 * 1000
There are three zeros in the number 1000. This means three zeros will be added onto the number 16
So the answer would be 16,000
Hope this helps!
Answer:
she should beat a speed of v₂ = 6.04 m/s in order to win the competition
Step-by-step explanation:
Since the momentum p is defined as
p = m*v
where
m= mass of the ball
v= velocity of the ball
denoting 1 and 2 as the first and second bowler , then to reach the momentum of the first bowler
p₂=p₁
therefore
m₁*v₁ = m₂*v₂
v₂ = v₁ * (m₁/m₂)
replacing values
v₂ = v₁ * (m₁/m₂) =8.6 m/s * (4.5 kg/6.4 kg ball) = 6.04 m/s
then since the momentum p = m*v increases with increasing v (at constant m) , she should beat a speed of v₂ = 6.04 m/s in order to win the competition

The correct answer is f(x)=-5+0.5x
Looking at the data, we can see that the data increases at a constant rate. We can find this rate, the slope, using the formula
m=(y₂-y₁)/(x₂-x₁)
Using the first two ordered pairs, we have
m=(1-0.5)/(12-11) = 0.5/1 = 0.5
Writing this in point-slope form, y-y₁=m(x-x₁), we have
y-0.5=0.5(x-11)
Using the distributive property, we have
y-0.5=0.5x-0.5*11
y-0.5=0.5x-5.5
Adding 0.5 to both sides,
y-0.5+0.5=0.5x-5.5+0.5
y=0.5x-5
Answer:
y = m x + b equation of straight line
Slope = (y2 - y1) / (x2 - x1) = (-3 - 1) / ((7 - (-5)) = -4 / 12 = -1 / 3
y = -x / 3 + b since m is defined above
lf y = 7 then x = -5 given
7 = 5/3 + b
b = (21 - 5) / 3 = 16 / 3 = 5 1/3
y = -x / 3 + 5 1/3
Check: Use point x = -5
y = 5/3 + 16/3 = 21 / 3 = 7 correct
