259 Students go on a field trip. There are 19 vehicles, some vans and some buses.
Sunny_sXe [5.5K]

Answer:

12 vans

7 Buses

Step-by-step explanation:

I tried multiple versions but I finally got it right.

Since the buses can hold 25 students at a time I multiplied it by 7.

7 x 25 = 175

Then you'll need to find the remainder.

259-175 = 84

This number would be used to find the students going in the van

84/7= 12

So in total there would be 12 vans

and 7 buses

I hope this helps

URGENT A virus is spreading by a factor of 2 every hour from 1:00 p.m. to 11:00 p.m. The function below shows the number of vira
Mars2501 [29]

Answer:

0 ≤ x ≤ 10

Step-by-step explanation:

The function representing the spread of virus is:

f(x)=20(2)^{x}

Where x represents the number of hours after 1:00 pm

So, at 1:00 pm "x" will be equal to 0. So the domain will start from x = 0

According to the given statement, the virus spreads from 1:00 pm to 11:00 pm. So, the number of hours starting from 1:00 pm and ending on 11:00 pm will be the Domain. 11:00 pm means 10 hours after 1:00 pm i.e. x = 10

So, the domains starts at x = 0 and ends at x = 10. Therefore, the correct answer is 0 ≤ x ≤ 10
