Answer:
<u>Number of rooms reserved for the students are - 90 .</u>
Step-by-step explanation:
Firstly ,
As we know 60% of the 600 students went on the trip,
Then ,
Number of students went on the trip = 60% of 600
= 
= 360
Now ,
Given - One room is reserved for 4 students ,
Therefore , Number of rooms for 360 students = 
= 90
<u>Hence , the answer is 90 rooms reserved for the students.</u>
The car's average rate is 43.7 mph. The bicycle's average rate is 12.3 mph.
To get this solution, let the bicycle's average rate be (x) and the car's average rate be (x + 31.4) mph.
Distance= Speed x Time
364 = (x + x + 31.4) 6.5
364 = (2x + 31.4) 6.5
364/6.5 = 2x + 31.4
56 = 2x + 31.4
56 - 31.4 = 2x
24.6 = 2x
24.6/2 = x
12.3 = x
x = 12.3 mph
x+31.4 = 43.7 mph
Step-by-step explanation:
integral fx = gx, gx = fx
gx = -4x2
variable of x2 = replace to left side it mean we got minus when Variable replace to left it mean minus
