Answer:

520 out of 800 students ride the bus

Step-by-step explanation:

Required

Determine the number of students $that\ ride\ the\ bus$

To do this, we simply multiply the proportion by the total number of students.

i.e.

$Bus = Proportion * Students$

$Bus = 65\% * 800$

Express the percentage as decimal

$Bus = 0.65* 800$

$Bus = 520$

Verdich [7]

Answer:

181 feets

Step-by-step explanation:

Given that:

Rate of change in water level = - 1.5 feets per month

Water level at beginning of May = 187 feets above sea level

Total change after four months = rate of change per month * number of months

Hence water level after 4 months :

187 feets + (-6 feets)

187 feets - 6 feets

= 181 feets
