a theater has 144 seats. the theater sells tickets for $6 per adult and $4 per child
Let x be the number of adult tickets
and y be the number of child tickets
Total number of tickets sold is 144
x + y = 144 -----------> equation 1
the theater sells tickets for $6 per adult and $4 per child and earned $660
6x + 4y = 660 ----------> equation 2
Solve for x and y
x + y = 144
y = 144 - x
Now plug it in second equation
6x + 4y = 660
6x + 4(144 - x) = 660
6x + 576 -4x = 660 (combine like terms)
2x + 576 = 660 (subtract 576 from both sides)
2x = 84 (divide by 2)
x= 42
Number of adult tickets = 42
y = 144 - x
y = 144- 42= 102
Number of child tickets = 102
Answer:
Step-by-step explanation:
Given radius of cylinder=5cm
Volume of cylinder=471cubic cm
Volume of cylinder=πr^2h
So πr^2h=471
3.14×5×5×h=471
78.5h=471
h=471/78.5
h=6cm
Answer:
The percent of pages Jace read at school is × 100 = 15%
The percent of pages Jace need to read at home is 100% - 15% = 85%
Step-by-step explanation:
Scale 1: One division represents 100% ÷ 20 divisions = 5%
Scale 2: One division represents 20 pages ÷ 20 divisions = 1 page
The proportion that can be used to determine the percentage of pages Jace read at school is 3 out 20 pages =
Jace need to read 20 - = pages at home.
That is × 100 = 85%
