Answer:
850 for student and 850 for students
Step-by-step explanation:
Let student tickets sold be=x
and adult tickets sold=y
They sold 5 times as many student tickets as adult tickets.
i.e. x=5y
The student tickets cost $2.00 each and
the adult tickets cost $4 each.
They made $140.
i.e. 2x + 4y = 140
Dividing both sides by 6, we get
x + 2y = 70
or 5y + 2y= 70
i.e. 7y=70
i.e. y=10
x= 5y
⇒ x = 50
Hence, Student tickets sold= 50
and Adult tickets sold= 10

An outdoor spa (hot tub) draws 1487 watts to keep the water warm. If the utility company charges $0.13 per kilowatt-hour, how much does it cost to operate the spa for four months during the winter (24 hours per day)? Assume each month has 30 days.
Answer:$556.73
Step-by-step explanation:
Watts (1487) multiplied by the hours used daily (24) =35688
Divided by 1000 = 35.68
multiply 35.68 times the number of days (120) = $556.73
Another example:
wattage x hours used ÷ 1000 x price per kWh = $$
1487 x 2880 ÷ 1000 x $0.13 = $556.73
Answer:
$556.7328 is total cost of operating hot tub for 4 months in an outdoor spa.
Step-by-step explanation:
Power drawn by hot tub = 1487 Watts = 1.487 kiloWatt
1 Watt = 0.001 kiloWatt
Utility charges charged by the company = $0.13 / (kiloWatt hour)
Charges in 1 day or 24 hours : (1 day = 24 hours)
$0.13 / (kiloWatt hour) × 1.487 kiloWatt × 24 hours = $4.63944
4 months = 4 × 30 = 120 days (1 month = 30 days)
Total charge for operating hot tub for 4 months or 120 days:
$4.63944 × 120 = $556.7328

give all possible proportions using the numbers 2 5 8 and 20
Answer:
[tex]\frac{2}{5},\frac{1}{4},\frac{1}{10},\frac{5}{2},\frac{5}{8},\frac{4}{1},\frac{8}{5},\frac{10}{1}[/tex]
Step-by-step explanation:
Proportions are fractions that can be created using the numbers given. Let's pair each and reduce if possible.
Starting with 2:
2/5
2/8 = 1/4
2/20 = 1/10
Then 5:
5/2
5/8
5/20 = 1/4
Then 8:
8/2 = 4/1
8/5
8/20 = 2/5
Lastly 20:
20/2 = 10/1
20/5 = 4
20/8 = 5/2
So, we can see some are repeating, hence the unique proportions are:
2/5, 1/4, 1/10, 5/2, 5/8, 4/1, 8/5, 10/1
The possible proportions using the numbers 2 5 8 and 20 are:
1. 2:5 = 8:20
2. 2:8 = 5:20
3. 5:20 = 2:8
4. 8:2 = 20:5
5. 20:5 = 8:2
6. 5:2 = 20:8
To create all possible proportions using the numbers 2, 5, 8, and 20, you can set up ratios and see how you can pair these numbers.
A proportion is essentially an equation that states two ratios are equal.
Here are some possible proportions you can create:
1. 2:5 = 8:20
(This is a direct proportion where both ratios reduce to 2:5.)
2. 2:8 = 5:20
(Again, this is a direct proportion where both ratios reduce to 1:4.)
3. 5:20 = 2:8
(This is just another way to write the second proportion.)
4. 8:2 = 20:5
(This is an inverse proportion where the first ratio is the reciprocal of the second.)
5. 20:5 = 8:2
(This is just another way to write the fourth proportion.)
6. 5:2 = 20:8
(This is an inverse proportion where the first ratio is the reciprocal of the second.)
7. 20:8 = 5:2
These are all the possible proportions you can create using the numbers 2, 5, 8, and 20. Note that in each proportion, you can switch the positions of the numbers (e.g., 2:5 = 8:20 is the same as 5:2 = 20:8), but the ratios remain the same.

4.In decimal form, what percent of Courtney’s paycheck is left after she pays her taxes and puts money into savings?
5.There is on average 4.35 weeks in a month. How much does Courtney make a month after taxes?
1. 612.85
14.42 x 42.5 = $612.85
2. 110.313
612.85 x .18 = $110.313
3. $72.063
110.313 - 38.25 = $72.063
4. %11.75
72.063 / 612.85 = 0.11758
0.11758 x 100 = %11.75
5. 479.861
110.313 x 4.35 = 479.861
Courtney's weekly earnings before taxes are $612.85. After an 18% tax, her earnings are $502.54, which becomes $464.29 after saving $38.25. The paycheck's remaining percentage is 75.76%, and her monthly earnings after taxes average $2,186.05.
Courtney earns $14.42 per hour and works 42.5 hours a week. To calculate her weekly earnings before taxes:
Weekly earnings = Hourly wage times Hours worked per week
Weekly earnings = $14.42 times 42.5
Weekly earnings = $612.85
To find out how much she makes after an 18% tax deduction:
Taxed amount = Weekly earnings times Tax rate
Taxed amount = $612.85 times 0.18
Taxed amount = $110.31
Earnings after tax = Weekly earnings - Taxed amount
Earnings after tax = $612.85 - $110.31
Earnings after tax = $502.54
After Courtney saves $38.25, her disposable weekly income is:
Money left to spend = Earnings after tax - Savings
Money left to spend = $502.54 - $38.25
Money left to spend = $464.29
Now, to calculate the percentage of paycheck left after taxes and savings:
Percentage left = (Money left to spend / Weekly earnings) times 100
Percentage left = ($464.29 / $612.85) times 100
Percentage left = 75.76%
For her monthly earnings after taxes, considering an average of 4.35 weeks per month:
Monthly earnings after taxes = Earnings after tax times Average weeks per month
Monthly earnings after taxes = $502.54 times 4.35
Monthly earnings after taxes = $2,186.05
The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere?
• 32 cm
87 cm
54 cm
167 cm
The volume of the given sphere is 32 cm³. Thus, the correct answer is option (A) 32 cm³.
Given that the diameter of the sphere is 4 cm, the radius is half of that or 2 cm.
The formula for the volume of a sphere is:
V = (4/3)πr³
Where r is the radius of the sphere.
Here, r = 2
Substituting these values into the formula, we get:
The volume of a sphere = (4/3) × π × (2)³
The volume of a sphere = (4/3)π(8)
The volume of a sphere = 32π/3
Using π = 3.14, we get:
The volume of a sphere ≈ 33.51 cm³
Therefore, the closest option to the volume of the sphere is 32 cm³.

Un triángulo rectángulo tiene un área de 84 pies2 y una hipotenusa de 25 pies de largo. ¿Cuáles son las longitudes de sus otros dos lados?
Answer:
7 feet and 24 feet
Step-by-step explanation:
In the right triangle, the hypotenuse is 25 feet long. The area of this triangle is 84 square feet.
Let x feet and y feet be the lengths of triangle's legs.
By the Pythagorean theorem,
[tex]x^2+y^2=25^2\\ \\x^2+y^2=625[/tex]
The area of the right triangle is half the product of its legs, thus
[tex]84=\dfrac{1}{2}xy\\ \\xy=168[/tex]
Solve the system of two equations:
[tex]\left\{\begin{array}{l}x^2+y^2=625\\ \\xy=168\end{array}\right.[/tex]
From the second equation:
[tex]x=\dfrac{168}{y}[/tex]
Substitute it into the first equation:
[tex]\left(\dfrac{168}{y}\right)^2+y^2=625\\ \\168^2+y^4=625y^2\\ \\y^4-625y^2+168^2=0\\ \\D=(-625)^2-4\cdot 168^2=(625-2\cdot 168)(625+2\cdot 168)=289\cdot 961=17^2\cdot 31\\ \\\sqrt{D}=17\cdot 31=527\\ \\y^2_{1,2}=\dfrac{-(-625)\pm 527}{2}=49,\ 576\\ \\y_1=7,\ y_2=-7,\ y_3=24,\ y_4=-24[/tex]
The length of the leg cannot be negative, so
[tex]y_1=7\Rightarrow x_1=\dfrac{168}{7}=24\\ \\y_2=24\Rightarrow x_2=\dfrac{168}{24}=7[/tex]

many votes did Alejandro receive? What percent of the votes did Laine receive?
Answer:
Alejandro received 6.51 million of votes
Laine received 58% of votes
Step-by-step explanation:
If the ratio of "Laine votes" to "Alejandro votes” was 29:21, then the number of "Laine votes" was 29x and the number of "Alejandro votes” was 21x. In total, 15.5 million votes were cast. So
29x + 21x = 15.5 million
50x = 15.5 million

If the perimeter of a square is 32 inches, what is the area
Final answer:
To find the area of a square when given its perimeter, divide the perimeter by 4 to find the side length and then square this length. Thus, a square with a perimeter of 32 inches has an area of 64 square inches.
Explanation:
If the perimeter of a square is 32 inches, we can calculate the length of one side by dividing the perimeter by 4, because a square has 4 equal sides. So each side is 32 inches ÷ 4, which equals 8 inches.
Once we have the side length, we can calculate the area of the square. The area of a square is determined by squaring its side length (side length × side length). In this case, the area would be 8 inches × 8 inches, which equals 64 square inches.
Therefore, the area of the square with a perimeter of 32 inches is 64 square inches.

Therefore, you get that the number of books that will printed in 305 runs is:
[tex]x=(1,512)(305)\\\\x=461,160\ books[/tex]
