There are 221 students on a field trip.

Liula [17]

Answer:

The answer is 31

Step-by-step explanation:

221 divided by 6 is 36-5=31

This is correct because if you divide 221 by 6 you get 36 the subtract 5 from 36 and get 31. To check this answer just do 31+5=36 times 6 which is 216 and 221 minus 5 is 216:)

Which describes Myra's distance as time increases?

DaniilM [7]

Answer:

(A)increasing

Step-by-step explanation:

Given the time and total distance ran by Myra in the table below.

$\left|\begin{array}{c|c}Time(minutes)&Distance(miles)\\--&--\\0&0.0\\2&0.4\\4&0.8\\6&1.2\\8&1.6\end{array}\right|$

We observe that as time increases, Myra's distance also increases. It is the speed(0.2 miles per minute) which is constant.

Therefore Option A is the correct option.
