The enthalpy of a reaction can be measured using a Calorimeter
Answer:
Step-by-step explanation:
80 minutes.......8 minutes played commercials....that means (80 - 8) = 72 minutes played music
so the ratio of music to commercials is : 72/8 which reduces to 9/1...so the ratio is 9:1 <=== ur answer
** pay attention to the wording, because if it would have asked for the ratio of commercials to music, it would have been 8/72....ratio would be 1:9
Number of game tokens is the label on x-axis.
<u>Step-by-step explanation</u>:
The equation is y = 0.5x + 3
Given,
- Admission charge = $3
- Cost of game token = $0.5 per game.
Total cost = admission charge + cost for number of game token
where,
- y represents the total cost
- x represents the number of game tokens.
B would have to equal 9 and a should equal -2 to get 0
Answer: f(a-2) = 2a² - 14a + 28
Step-by-step explanation:
f(x) = 2x² - 6x + 8
you can take a-2 and substitute it for each x, which would look like this:
f(a-2) = 2(a-2)² - 6(a-2) + 8
then distribute those in ( )
f(a-2) = 2a² - 8a + 8 - 6a + 12 + 8
combine like terms
f(a-2) = 2a² - 14a + 28
