At a movie theater, the price of 2 adult tickets and 4 child tickets is $48. The price of 5 adult tickets and 2 child tickets is $64. What is the ticket price for one adult and for one child?
Adult: Child:
Answers
Answer:
adult=10
Child=7
One adult and one child=10+7=17
Step-by-step explanation:
Let a be the price of an adult ticket
c = price of the child ticket
2a+4c = 48
5a+2c = 64
Multiply the second equation by -2 and add to the first equation
2a+4c = 48
-10a-4c = -128
---------------------
-8a +0c = -80
Divide by -8
-8a/-8 = -80/-8
a = 10
Now find c
2a+4c=48
2(10)+4c=48
20+4c=48
4c=48-20
4c=28
4c/4=28/4
c=7

Answers
To work out the area of the semi circle you do pi (3.14) x the radius squared, the radius is half the diameter.
3.14 x 4 squared
3.14 x16 = 50.24ftsqaured for the whole circle so you divide it by 2 which is 25.12ft squared.
And then finally you add 25.12 and 80 so your answer is 105.12 ft squared
A large pool has a faucet to allow water to enter the pool and a drain to allow water to leave the pool.
Each minute, the faucet allows 1215 gallons of water to enter the pool, and the drain allows 1523 gallons to leave the pool.
What is the change in the amount of water in the pool after 112 minutes?
Enter your answer as a simplified mixed number by filling in the boxes. FRACTION PROBLEM
Answers
Answer:
-34496 gallons = 34496 gallons less
Step-by-step explanation:
In 112 minutes, 1215(112) = 136080 gallons of water is added by the faucet
In 112 minutes, 1523(112) = 170576 gallons of water are drained from the pool.
So, assuming that the pool is not completely drained in the 112 minute time interval, the change in the amount of water = 136080 - 170576 = -34496 gallons; i.e., the amount of water in the pool is 34496 gallons less.

Line b passes through points (6, 7) and (1, 1). Line c passes through points (7, 10) and (2, 4). Are line b and line c parallel or perpendicular?
Answers
Answer:
b and c are parallel lines
Step-by-step explanation:
Parallel lines have equal slopes
The product of the slopes of perpendicular lines = - 1
Calculate the slopes m of the lines using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (6, 7 ) and (x₂, y₂ ) = (1, 1 )
[tex]m_{b}[/tex] = [tex]\frac{1-7}{1-6}[/tex] = [tex]\frac{-6}{-5}[/tex] = [tex]\frac{6}{5}[/tex]
Repeat with (x₁, y₁ ) = (7, 10 ) and (x₂, y₂ ) = (2, 4 )
[tex]m_{c}[/tex] = [tex]\frac{4-10}{2-7}[/tex] = [tex]\frac{-6}{-5}[/tex] = [tex]\frac{6}{5}[/tex]
Since slope are equal then line b and line c are parallel lines
