The teachers plan will raise money is 1.8 times the static graders plan.The teachers plan to raise a dollar is 5/6 times the static graders plan to raise a dollar.More dollars will be raised by the teachers plan compared to the static graders plan.
Step-by-step explanation:
In the question,
Let what the static graders plan to rise to be $x.
Let what the teachers plan to rise to be $ y
You understand that ;
y =210 +x ----------------(this is 210 dollars more than the static graders raise)
y=x+4/5 x -------------------(but only 4/5 as much as the static graders)
Solving the equations to get x and y
210+x=x+4/5x
5(210+x)=5*x+4x
1050+5x=5x+4x
1050=5x+4x-5x
1050=4x
1050/4=4x/4
x=$262.50
y=210+262.50=$472.50
Additionally, for every $60 raised in teachers plan, the static graders raise $50
This means in teachers plan 1$ raised equals 5/6$ raised in static plan
y=5/6x

Answer:
<em>f(50) = 109.44943 feet</em>
Step-by-step explanation:
<u>Modeling</u>
The model of a situation where the skid distance f is measured against the car speed x can be expressed as:
Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:
f(50) = 109.44943 feet
Answer is 1/12
Two ways to work this.
1) divide each of the given portions into 20 parts and add the resulting fractions.
.. (1 2/3)/20 = 1/20 + (2/3)*(1/20)
.. = 1/20 + 1/30
.. = 3/60 + 2/60
.. = 5/60 = 1/12
2) convert 1 2/3 to an improper fraction and divide by 20.
.. (1 2/3)/20 = (5/3)*(1/20)
.. = (5*1)/(3*20)
.. = 5/60 = 1/12
Hi there!
Amit's estimate would be a close estimate!
If you add the fractions together and put it in decimal form you get 4.96 which is very close to Amit's estimate of 5.
