Answer:

Angela, a proportion is two equal ratios, kinda like 3/4 = 6/8.

If we call the number of cars c, then our proportion is 3/10 = c/100.

Cross multiplying, we get 10c = 300.

Dividing both sides by 10, c = 30.

ryzh [129]

Answer:

T(t) = 3sin((t-5)π/30)

Step-by-step explanation:

T(t) = 3sin((t-5)π/30)
