x(t) = 20t
y(t) = 40t - 5t^2
Since we are only interested in comparing the two at time t = 5 seconds, we plug in 5 everywhere we see the variable t and then compare x and y
x(5) = 20(5) becomes x(5) = 100
y(5) = 40(5) - 5(5)^2 becomes y(5) = 200 - 125 and then y(5) = 75
The ratio of y to x can be expressed as: y/x, so we can say the ratio is equal to 75/100 or 0.75
Answer: 0.75
You can make a ratio of red to overall colors and then that will give you the fraction, you might have to simplify it
Answer:
40
Step-by-step explanation:
9a + 9b + 9c = 5
Multiply the equation by 8
8*(9a + 9b + 9c )= 5*8
Distribute
72a +72b +72 c = 40
