Answer:

Step-by-step explanation:

School A rented and filled 8 vans. Then, they had 8 buses with 240 students.

8x + 8y = 240

School B rented and filled 4 vans and 1 bus with 54 students. It says "Every van had the same number of students and every bus had the same number of students."

So, 4x + y(1) = 54

Y can be classified as the bus since its only 1, and both of them have the same number of students.

Hope the explanation helped,

hope you have a good day :]

In stage 2 of a rocket's takeoff, the speed of the rocket increases at a rate of 4.3% per minute. The speed of the rocket at the

Sveta_85 [38]

The correct option is: B. $25000=5000(1.043)^t$

Explanation

The general form of growth equation is: $A=P(1+r)^t$ , where A = final amount, P = initial amount, r = growth rate in decimal form and t = time duration

Here, the speed of the rocket at the beginning was 5,000 kilometers per hour and at the end will be 25,000 kilometers per hour. The speed increases at a rate of 4.3% per minute.

That means, $A= 25000 , P= 5000, r= 4.3\% = 0.043$

Now plugging these values into the above equation, we will get......

$25000=5000(1+0.043)^t\\ \\ 25000=5000(1.043)^t$

So, the equation that could be used to determine the time for the speed of the rocket to reach 25,000 kilometers per hour will be: $25000=5000(1.043)^t$
