At the movie theatre, child admission is $5.50 and adult admission is $9.40 . On Monday, four times as many adult tickets as child tickets were sold, for a total sales of $1379.20 . How many child tickets were sold that day?

Answers

5.50c + 9.40a = 1379.20
a = 4c

5.50c + 9.40(4c) = 1379.20
5.50c + 37.6c = 1379.20
43.1c = 1379.20
c = 1379.20 / 43.10
c = 32 <=== 32 kids tickets

a = 4c
a = 4(32)
a = 128 <=== 128 adult tickets

remmeber, you can do anything to an equation as long as you do it to both sides

for inequalities, if you multiply or divide both sides by a negive, flip the direction of the inequality sign

pemdas always applies
but also the commutative property and assiociative property

so
2(5y+13)-6<20
add 6 both sides
2(5y+13)<26
divide both sides by 2 (easier that distributing)
5y+13<13
minus 13 both sides
5y<0
y<0 is the solution

Best buy shoes had a back to school special. The total bill for four pairs of shoes came to $69.24 ( before tax ) What was the average price for each pair of shoes?
QUESTION 2 If you only purchased 1 pair of shoes at Best Buy Shoes instead of the four described in problem 20, how much would you have paid, based on the average price?

Answers

Answer: a) $17.31, b) $17.31.

Step-by-step explanation:

Since we have given that

Total bill for four pairs of shoes = $69.24

Number of pairs of shoes = 4

We need to find the average price for each pair of shoes .

So, Average price would be

[tex]\dfrac{\text{Total amount}}{\text{Number of pairs of shoes}}\\\\=\dfrac{69.24}{4}\\\\=\$17.31[/tex]

If he purchased only 1 pair of shoes, the amount he has to pay based on average price would be $17.31.

Hence, a) $17.31, b) $17.31.

Final answer:

The average price for each pair of shoes from the total bill of $69.24 is $17.31. If only one pair of shoes was purchased, it would also cost $17.31.

Explanation:

To find the average price for each pair of shoes in the first question, you divide the total bill by the number of pairs of shoes. In this case, the total bill is $69.24 for four pairs of shoes.

Step-by-step calculation:

Divide the total cost ($69.24) by the number of pairs (4).

The calculation will be $69.24 / 4 = $17.31.

The average price for each pair of shoes is $17.31.

For the second question, if you were to purchase only one pair of shoes, the cost would be equal to this average price, which is $17.31.

please answer both questions thank you.

Write the equation of a line that has a slope 1/3 and y-intercept 4.

Answers

Y=mx+b, where m represents the slope and b represents the y-intercept. If you plug in the numbers, you get the equation, y=(1/3)x+4
Final answer:

In slope-intercept form, y = (1/3)x + 4 can be used to represent the equation of a line with a slope of 1/3 and a y-intercept of 4.

Explanation:

In mathematics particularly in algebra, the equation of a line is usually formulated in the slope-intercept form, which is y = mx + b. Where m is the slope of the line and b is the y-intercept. For a line with a slope of 1/3 and y-intercept of 4, you would substitute 1/3 for m and 4 for b. Therefore, the equation of the line would be y = (1/3)x + 4

ax+2xy=14 solving for y

Answers

y= (14-Ax)/(2x); you first subtract the Ax on both sides, then divide by 2x for both sides and your result is fourteen minus Ax divided by 2x.

Answer:

[tex]y=\dfrac{14-Ax}{2x}[/tex]

Step-by-step explanation:

The given expression is :

[tex]Ax+2xy=14[/tex].............(1)

We need to find the value of y. Subtracting "Ax" on both sides of equation (1) as :

[tex]Ax-Ax+2xy=14-ax[/tex]

[tex]2xy=14-Ax[/tex]

Dividing both sides of above equation by "2x" as :

[tex]\dfrac{2xy}{2x}=\dfrac{14-Ax}{2x}[/tex]

[tex]y=\dfrac{14-Ax}{2x}[/tex]

So, the value of y is, [tex]y=\dfrac{14-Ax}{2x}[/tex]. Hence, this is the required solution.

For about 10 years after the french revolution, the french government attempted to base measures of time on multiples of ten: one week consisted of 10 days, one day consisted of 10 hours, one hour consisted of 100 minutes, and one minute consisted of 100 seconds. what are the ratios of (a) the french decimal week to the standard week and (b) the french decimal second to the standard second? assume that the definition of a "day" remains the same.

Answers

Final answer:

Explanation of the ratios of French decimal time to standard time after the French Revolution.

Explanation:

Ratio of French Decimal Week to Standard Week:

1 French decimal week = 10 days, whereas 1 standard week = 7 days. So, the ratio is 10/7.

Ratio of French Decimal Second to Standard Second:

1 French decimal second = 0.01 standard second since 1 hour = 100 French decimal minutes = 100 x 0.01 = 1 standard hour.

(a) The ratio of the French decimal week to the standard week is [tex]\( \frac{10}{7} \)[/tex].

(b) The ratio of the French decimal second to the standard second is [tex]\( \frac{5}{3} \)[/tex].

To find the ratios of the French decimal week to the standard week and the French decimal second to the standard second, we'll compare the durations of these units in the French decimal system to those in the standard system.

(a) Ratio of the French decimal week to the standard week:

In the French decimal system:

- One French decimal week consists of 10 days.

In the standard system:

- One standard week consists of 7 days.

So, the ratio of the French decimal week to the standard week is:

[tex]\[ \text{Ratio} = \frac{\text{French decimal week}}{\text{Standard week}} = \frac{10 \text{ days}}{7 \text{ days}} \][/tex]

(b) Ratio of the French decimal second to the standard second:

In the French decimal system:

- One minute consists of 100 seconds.

In the standard system:

- One minute consists of 60 seconds.

So, the ratio of the French decimal second to the standard second is:

[tex]\[ \text{Ratio} = \frac{\text{French decimal second}}{\text{Standard second}} = \frac{100 \text{ seconds}}{60 \text{ seconds}} \][/tex]

Now, let's simplify these ratios:

(a) Ratio of the French decimal week to the standard week:

[tex]\[ \frac{10}{7} \][/tex]

(b) Ratio of the French decimal second to the standard second:

[tex]\[ \frac{100}{60} = \frac{5}{3} \][/tex]

So, the ratios are:

(a)  for the French decimal week to the standard week.

(b) [tex]\( \frac{5}{3} \)[/tex] for the French decimal second to the standard second.

A scientist inoculates mice, one at a time, with a disease germ until he finds 2 that have contracted the disease. if the probability of contracting the disease is 1/6, what is the probability that 8 mice are required?

Answers

There are several possible events that lead to the eighth mouse tested being the second mouse poisoned. There must be only a single mouse poisoned before the eighth is tested, but this first poisoning could occur with the first, second, third, fourth, fifth, sixth, or seventh mouse. Thus there are seven events that describe the scenario we are concerned with. With each event, we want two particular mice to become diseased (1/6 chance) and the remaining six mice to remain undiseased (5/6 chance). Thus, for each of the seven events, the probability of this event occurring among all events is (1/6)^2(5/6)^6. Since there are seven of these events which are mutually exclusive, we sum the probabilities: our desired probability is 7(1/6)^2(5/6)^6 = (7*5^6)/(6^8).
