Question

ambulances are sometimes used to fight fires. a certain airplane can deliver $2.19×10^4$ liters of water in one trip. how m trips?
write your answer in scientific notation.
liters
$\square \times 10^{\square}$

Explanation:

Step1: Identify the given value

The airplane can deliver \(2.19\times10^{4}\) liters of water in one trip. Wait, the problem seems incomplete? Wait, maybe it's "how many liters in 5 trips"? Let's assume that (since the original problem might have a typo, like "how many liters in 5 trips?"). So we need to multiply the amount per trip by the number of trips. Let's assume the number of trips is 5 (since there's a 5 button in the interface).

Step2: Multiply the two numbers

To find the total liters in 5 trips, we multiply \(2.19\times10^{4}\) by 5.
First, multiply the coefficients: \(2.19\times5 = 10.95\)
Then, keep the power of 10: \(10.95\times10^{4}\)
But in scientific notation, the coefficient must be between 1 and 10. So we rewrite \(10.95\) as \(1.095\times10^{1}\)
Then, \(1.095\times10^{1}\times10^{4}=1.095\times10^{1 + 4}=1.095\times10^{5}\)

Answer:

\(1.095\times10^{5}\) liters (assuming 5 trips, as the problem's original text might have a missing number of trips, likely 5 from the interface)
