Answer:
B. neither perpendicular nor parallel
Step-by-step explanation:
If the lines were perpendicular, the coefficients would be swapped and one negated. (You would have 8x -y = c, or 9x +2y = c in the system.)
If the lines were parallel, the coefficients in the two equations would only differ by a common factor. (Both equations would reduce to 2x -9y = c, or x +8y = c.)
The lines are not the same line (coefficients are different).
So, the only reasonable description is ...
neither perpendicular nor parallel

=============================================================
Explanation:
On day 56, the amount of money brought in was 2.95 million.
Then on day 112, the money earned was 0.279 million
We'll subtract those two dollar figures to get
0.279 - 2.95 = -2.671
The negative result is to indicate a decrease. So the studio has missed out on about 2.671 million dollars.
This value is then divided by the difference in the number of days (112-56 = 56), so we get -2.671/56 = -0.047696 which is approximate.
Rounding to two decimal places leads to the final answer -0.05
The amount earned has dropped by about 0.05 million dollars per day, or 50 thousand dollars per day. This is the amount of money they are missing out on as less people go to see the movie. This figure is approximate because we're talking about the average rate of change over a certain period of time.
---------------------------
This is what your steps could look like if you don't like the approach of the last section.
m = average rate of change
m = ( f(b) - f(a) )/(b - a)
m = ( f(112) - f(56) )/(112 - 56)
m = ( 0.279 - 2.95 )/( 112 - 56 )
m = (-2.671)/(56)
m = -0.047696
m = -0.05

Answer:
$1.475 is the average amount of snack sales per ticket sold.
Step-by-step explanation:
We are given the following in the question:
Number of popcorn bags sold = 3
Cost of a popcorn bag = $2.25
Total cost of popcorn bag = = $6.75
Number of soda sold = 4
Cost of a soda = $1.50
Total cost of soda = = $6.00
Number of candy bars sold = 2
Cost of a candy bar = $1.00
Total cost of candy bars = = $2.00
Total sales =
Total cost of popcorn + Total cost of soda + Total cost of candy bar
Average amount of snack sales per ticket sold =
Thus, $1.475 is the average amount of snack sales per ticket sold.
Answer and Step-by-step explanation:
Divide both numbers by 5kg to know how much R is for 1 kg.
= 3.1.
It is 3.1 for 1 kg.
