Answer: the percent change in attendance from 2014 to 2015 is 11.54%
Step-by-step explanation:
In 2014, the total attendance at Jefferson school's Fall festival was 650.
In 2015, the attendance was 575. The change in the number of attendees between 2014 and 2015 is 650 - 575 = 75
There was a decrease in the number of attendees between 2014 and 2015.
The percent change in attendance from 2014 to 2015 would be attendance in 2015 divided by attendance in 2014 and multiplied by 100. It becomes
75/650 × 100 = 11.54%
Answer:
- 3 hours
- 1 hour 45 minutes
- 300 miles
Step-by-step explanation:
1. The trains are moving toward each other at a total speed of 50 +20 = 70 miles per hour. Together, they cover the 210 mile distance in ...
time = distance/speed
time = 210 mi/(70 mi/h) = 3 h
The trains collide after 3 hours.
__
2. The fly is closing with the freight train at a speed of 100 +20 = 120 miles per hour. Together, the fly and the train cover the initial 210 mile distance in ...
(210 mi)/(120 mi/h) = 7/4 h = 1 hour 45 minutes
The fly first meets the oncoming freight train after 1 h 45 min.
__
3. The fly is flying for all three hours before the trains collide, so, at 100 miles per hour, will fly 300 miles.
The statements that are true are:
First option: All functions have dependent a variable
Second option: All functions have an independent variable.
Fifth option: A horizontal line is an example of a functional relationship
X × x = x^2
x × -3 = -3x
3 × x = 3x
3 × -3 = -9
x^2 + 3x - 3x - 9
So I would agree with C because the -3x and the 3x cancel each other out. I hope this helps!
