One way that double number lines are similar to finding equivalent ratios is that to find your answer on a double number line, you add equivalent ratios to your number line.
You can really just use a calculator...........

Answer:
h(t) = –16t^2 + 46*t + 6
Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached image below, to find more information about the graph
The projectile formula is
h(t) = -16*t^2 + v*t + h0
Where,
v = initial vertical velocity of the ball in feet per second
h0 = initial height of the ball in feet
We need to fill the equation
h(t) = –16t^2 + v*t + 6
Where
v is the missing speed
If we go through many values of v until we find the same graph as the one showed in the first picture, we can find that
v = 46 ft/s
First we convert 6 kg to grams which should be 6000 grams, since there are 1000 grams in one kg.
Subtract 2500 from 6000 and we get 3500 grams, which is your answer
71% of 40 is 28.4
Divide 28.4 by 40:
Change the decimal to a percentage by multiplying by 100:
