A movie theater has a seating capacity of 271. The theater charges $5.00 for children, $7.00 for students,

nirvana33 [79]

Answer:

Children attended = 154

Students attended = 40

Adults attended = 77

Step-by-step explanation:

Seating capacity = 271

Charges for each children ticket = $5

Charges for each student ticket = $7

Charges for each adult ticket = $12

Let number of children tickets = $2x$

Ticket price for children = $\$ 2x \times 5$

As per question statement, there were half as many adults as there are children,

so number of adult tickets = $x$

Ticket price for adults = $\$ x \times 12$

Now, number of students =

$(271-x-2x)\\\Rightarrow (271-3x)$

Ticket price for students = $\$ (271-3x) \times 7$

Total ticket sales = $1974

$\Rightarrow 12x+2x\times 5 +(271-3x)\times 7 = 1974\\\Rightarrow 22x-21x +(271 \times 7) = 1974\\\Rightarrow x = 1974 - 1897\\\Rightarrow x = 77$

So, number of adults attended = 77

number of children attended = 77 $\times$ 2 = 154

number of students attended = 271 - 77 - 154 = 40

Simplify 5(5t+6)+2 (2t-3)

yan [13]

Answer:

29t + 24

Step-by-step explanation:

5(5t + 6) + 2(2t - 3)

Open Parentheses first.

5* 5t = 25t

5 * 6 = 30

25t + 30 + 2(2t - 3)

Open others

2 * 2t = 4t

2 * 3 = 6

25t + 30 + 4t - 6

Kendra ordered a set of blue and brown pins. She received 100 pins, and 30% of them were blue. How many blue pins did Kendra rec

natka813 [3]

Answer:

30 blue pins

Step-by-step explanation:

30% is the same as 30 out of 100, so this can be written in this fraction: $\frac{30}{100}$

now, you should multiply this fraction by the total number of pins she ordered:

100 x $\frac{30}{100}$

to solve this, you can simplify by dividing 100 by 100, this equals 1

30 times 1 is 30

there are 30 blue pins

A football quarterback enjoys practicing his long passes over 40 yards. He misses the first pass 40% of the time. When he misses

laila [671]

Answer:

Probability of missing two passes in a row is 0.08.

Step-by-step explanation:

Event E = A football player misses twice in a row.

P(E) = ?

Event X = Football player misses the first pass

P(X) = 0.4

Event Y = Football player misses just after he first miss

P(Y) = 0.2

Both the events are exclusive so the probability of occuring of these two events can be calculated by the formula:

P(E) = P(X).P(Y)

P(E) = 0.4*0.2

P(E) = 0.08
