Answer:
y = 72x
324miles
Step-by-step explanation:
Given parameters:
Speed of the car = 72miles/hr
distance = y
time = xhrs
Unknown:
Write a direct variation equation for the distance= ?
Distance covered in 4.5hrs =?
Solution:
A. Write a direct variation equation for the distance;
A direct variation is a linear equation.
It often takes the form y = kx
For this problem;
Distance = speed x time
input the parameters;
y = 72x
The direct variation equation is y = 72x
B. Distance traveled in 4.5hrs
y = 72x
x is the time taken;
So;
y = 72 x 4.5 = 324miles
Solution
2014 - 1969 = 45
45 x 0.2633 = 11.8485 = 12
Final Answer:
C) 26.33%
Answer:
4/3
d/c
Step-by-step explanation:
You divide 16 by 4 and you get 4, so 4 dogs.
Then you divide 12 by 4 and you get 3, so 3 cats.
Lastly you were comparing dogs to cats so you have to put the about of days first then the amount of cats last.
The final answer is 4/3.
