#1. It helps to write everything out:
Sell price for boxes of cookies: $4.25x (x representing number of boxes)
Cost of each carton: $30y (y representing number of cartons)
The group bought 6 cartons, so we substitute y for 6:
30(6) = $180 they spent on the cartons.
Each carton contains one dozen boxes of cookies. In other words, 12 boxes of cookies. WIth 6 cartons purchased, we multiply 6 with 12 to get 72 boxes of cookies total they sold. Now we substitute x for 72:
4.25(72) = $306 they earned.
#2. The pattern is 2x + 5 = y where x represents the number of rides and 5 represents the admission. The y represents the total cost. Simply plug in the x's in the table into this equation to get the answer for y.

[Quick Answer Needed] Which of the following shows the extraneous solution to the logarithmic equation?
(Image Attached Below)
Answer:
C
Step-by-step explanation:
Given the logarithmic equation
[tex]\log_4x+\log_4(x-3)=\log_4(-7x+21)[/tex]
First, notice that
[tex]x>0\\ \\x-3>0\Rightarrow x>3\\ \\-7x+21>0\Rightarrow 7x<21\ x<3[/tex]
So, there is no possible solutions, all possible solutions will be extraneous.
Solve the equation:
[tex]\log_4x+\log_4(x-3)=\log_4x(x-3),[/tex]
then
[tex]\log_4x(x-3)=\log_4(-7x+21)\\ \\x(x-3)=-7x+21\\ \\x^2-3x+7x-21=0\\ \\x^2+4x-21=0\\ \\D=4^2-4\cdot 1\cdot (-21)=16+84=100\\ \\x_{1,2}=\dfrac{-4\pm 10}{2}=-7,\ 3[/tex]
Hence, [tex]x=3[/tex] and [tex]x=-7[/tex] are extraneous solutions

What is _- 20 - 3 1/4 = 14 5/8
Answer:
37 7/8
Step-by-step explanation:
First you make the equation
14 5/8 = _ - 20 - 3 1/4
They all have to make 14 5/8 so then solve
x+-93/4 = 117/8
x=303/8
Simplified:
x=37 7/8
To solve the equation -20 - 3 1/4 = 14 5/8, start by simplifying the mixed number and converting it to an improper fraction. Then, find a common denominator for the fractions and add them. Simplify and multiply both sides by -2 to eliminate the fractions.
Explanation:To solve the equation: -20 - 3 1/4 = 14 5/8, you can start by simplifying the mixed number and converting it to an improper fraction.
-20 can be written as -20/1, so the equation becomes:
-20/1 - 13/4 = 117/8.
Next, find a common denominator for the fractions. The common denominator for 1 and 4 is 4, so the equation becomes:
-80/4 - 13/4 = 117/8.
Now, you can add the fractions:
(-80 - 13)/4 = 117/8.
Simplify:
-93/4 = 117/8.
Finally, multiply both sides by -2 to eliminate the fractions:
-93/4 * -2 = 117/8 * -2.
The final answer is:
186/4 = -234/8.
Simplify:
93/2 = -117/4.

The maximum number of volts, E, that can be placed across a resistor is given by the formula E = , where P is the number of watts of power that the resistor can absorb and R is the resistance of the resistor in ohms. Find E if P = 2 watts and R200 ohms.
Final answer:
The maximum number of volts that can be placed across the resistor is 20 volts.
Explanation:
The maximum number of volts, E, that can be placed across a resistor is given by the formula E = √(P * R), where P is the number of watts of power that the resistor can absorb and R is the resistance of the resistor in ohms. To find E, we can substitute the given values for P and R into the formula and solve:
E = √(2 * 200) = √(400) = 20 volts
Therefore, the maximum number of volts that can be placed across the resistor is 20 volts.
The maximum number of volts E that can be placed across the resistor is 20 volts.
The maximum number of volts, E, that can be placed across the resistor is given by the square root of the product of power P and resistance R. Therefore, E can be calculated as follows:
[tex]\[ E = \sqrt{P \times R} \][/tex]
[tex]\[ E = \sqrt{2 \text{ watts} \times 200 \text{ ohms}} \][/tex]
[tex]\[ E = 20 \text{ volts} \][/tex]
The formula provided in the question is [tex]\( E = \sqrt{P \times R} \),[/tex] where E is the maximum number of volts that can be placed across a resistor, P is the power in watts, and R is the resistance in ohms.
This formula is derived from the power equation [tex]\( P = \frac{V^2}{R} \),[/tex]where V is the voltage across the resistor.
Given that the power P is 2 watts and the resistance R is 200 ohms, we substitute these values into the formula to find E:
[tex]\[ E = \sqrt{2 \times 200} \][/tex]
[tex]\[ E = \sqrt{400} \][/tex]
The square root of 400 is 20, so the maximum number of volts E that can be placed across the resistor is 20 volts.
This is the voltage at which the resistor will absorb the maximum power of 2 watts without being damaged, assuming the resistor is operating at its maximum power rating.

The area of circle is equal to
[tex]A=\pi r^{2}[/tex]
The area of circle subtends a central angle of 360 degrees
so
using proportion
Find out the area of a sector [tex]A_s[/tex] by a central angle of ∅ degrees
[tex]\frac{\pi r^{2}}{360^o}=\frac{A_s}{\theta}[/tex]
[tex]A_s=\frac{\pi r^{2}}{360^o}{\theta}[/tex]
Part B) Verify each case

radius = 4 cm
angle = 105°
area = 16.7 cm 2
Find the area of the sector and then compare with the value of the given area
assume
[tex]\pi=3.14[/tex]
substitute the given values
[tex]A_s=\frac{(3.14)(4)^{2}}{360^o}{105^o}[/tex]
[tex]A_s=14.7\ cm^2[/tex]
so
The given value of area is not correct
case 3) we have
radius = 6 cm
angle = 85°
area = 23.7 cm 2
Find the area of the sector and then compare with the value of the given area

so
The given value of area is correct
What is the slope of the line that passes through the points (2, 0) and (1,0)? Write your answer in simplest form.
Answer: slope = 0
Step-by-step explanation:
The formula for calculating slope is given as :
m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]x_{1}[/tex] = 2
[tex]x_{2}[/tex] = 1
[tex]y_{1}[/tex] = 0
[tex]y_{2}[/tex] = 0
Substituting into the formula , we have
m = [tex]\frac{0}{-1}[/tex]
m = 0
The slope of the line passing through (2, 0) and (1, 0) is 0, indicating that the line is horizontal.
Explanation:The slope of a line that passes through the points (2, 0) and (1,0) can be determined using the formula for slope, which is (y2 - y1) / (x2 - x1).
Plugging in the coordinates, we get (0 - 0) / (1 - 2), which simplifies to 0/-1.
The slope of this line is 0. This indicates that the line is horizontal because there is no change in the y-value as the x-value changes.

A recipe for zucchini muffins states that it yields 12 muffins, with 250 calories per muffin. You instead decide to make mini-muffins, and the recipe yields 20 muffins. If you eat 4, how many calories will you consume?(note: There are several possible solution pathways to answer this question. )
Answer:
600
Step-by-step explanation:
first you need to find the calories for the entire batter:
12 muffins x 250 cal = 3000 cal
then you divide the total calories by 20:
3000/20 = 150
then multiply 150 by 4:
150 x 4 = 600
To find the caloric content of each mini-muffin, divide the total calories in the recipe by the new yield to find that each mini muffin is 150 calories. Consuming 4 mini muffins will total 600 calories.
Explanation:The caloric content of a full-size muffin is 250 calories. If we reduce the size of the muffins we make from the recipe, it doesn't alter the total caloric content of the whole batch – it just redistributes those calories across more muffins. To calculate the number of calories in one mini-muffin, we need to divide the total number of calories in the entire recipe (250 calories/muffin * 12 muffins = 3000 calories) by the total yield of mini-muffins, which is 20. This results in 3000 calories/20 mini-muffins = 150 calories per mini-muffin. If you consume 4 mini-muffins, you'd be consuming 4 * 150 calories = 600 calories.

Carlos is changing his health care insurance and deciding between two different pans that charge the same premium.
Plan A has a $1,200 deductible with 30% coinsurance. Plan B has a $1,500 deductible with 25% coinsurance. Carlos had a total of $6,350 in medical bills last year. Under which plan would Carlos share have been less?
Support your answer with mathematical calculations. Answer in complete sentence.
Answer:
Carlos would pay lower out-of-pocket costs if he picks over plan B.
Step-by-step explanation:
Let's make the comparison between plan A and plan B, this way:
Medicals bills = US$ 6,350
Plan A
6,350 - 1,200 = 5,150 * 30% = 5,150 * 0.3 = 1,545
Total out-of-pocket costs = 1,200 + 1,545 = $ 2,745
Plan B
6,350 - 1,500 = 4,850 * 25% = 4,850 * 0.25 = 1,212.50
Total out-of-pocket costs = 1,500 + 1,212.50 = $ 2,712.50
Carlos would pay lower out-of-pocket costs if he picks over plan B.
find the tangent of the angle in between the lines 2x+3y–5=0 and 5x=7y+3?
The tangent of the angle between two lines can be calculated using the slopes of the lines and applying them in the formula: Tan θ = (m2-m1) / (1 + m1*m2). The slopes of the given lines 2x+3y–5=0 and 5x=7y+3 are -2/3 and 5/7 respectively. These values are used in the formula to get the tangent of the angle.
Explanation:The subject of the given problem is concerning finding the tangent of the angle in between two lines namely, 2x+3y–5=0 and 5x=7y+3. First, we should understand that the tangent of the angle between two lines can be calculated using the formula:
Tan θ = (m2-m1) / (1 + m1*m2)
Where 'm1' and 'm2' are the slopes of two lines and 'θ' is the angle between them. Firstly, we need to put the equation in the form of y=mx+b to determine the slopes. So, the slope of the first line is -2/3 (m1) and of the second line is 5/7 (m2).
Using these values in the formula, we can find:
Tan θ = ((5/7) - (-2/3)) / (1 + (-2/3)*(5/7))
By calculating the above expression using basic arithmetic you will find the required answer.

Final answer:
The tangent of the angle between the two lines 2x+3y-5=0 and 5x-7y-3=0 is found by calculating the slopes of each line, then using the formula for the tangent of the angle between two lines. The result is a tangent of the angle of -29/11.
Explanation:
To find the tangent of the angle between the given lines, we need to first find the slope of each line. The slope of a line in the form ax + by + c = 0 is -a/b. Thus, the slope of the first line 2x + 3y – 5 = 0 is -2/3, and the slope of the second line 5x - 7y - 3 = 0 is 5/7. Now, using the formula for the tangent of the angle between two lines, which is tan(θ) = (m1 - m2)/(1 + m1*m2), where m1 and m2 are the slopes of the two lines, we get:
tan(θ) = ((-2/3) - (5/7))/(1 + (-2/3)*(5/7))
tan(θ) = (-14/21) - (15/21))/ (1 - (10/21))
tan(θ) = (-29/21) / (11/21)
tan(θ) = -29/11
Therefore, the tangent of the angle between the two lines is -29/11.

2x - 3y = 13 x + 2y = -4
Answer:
(2, - 3 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 13 → (1)
x + 2y = - 4 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = - 4 - 2y → (3)
Substitute x = - 4 - 2y into (1)
2(- 4 - 2y) - 3y = 13 ← distribute and simplify left side
- 8 - 4y - 3y = 13
- 8 - 7y = 13 ( add 8 to both sides )
- 7y = 21 ( divide both sides by - 7 )
y = - 3
Substitute y = - 3 into (3) for corresponding value of x
x = - 4 - 2(- 3) = - 4 + 6 = 2

Four pounds of gas occupy 10ft^3. What would be it’s density and specific gravity
Answer:
[tex]\large \boxed{\text{ 0.4 lb/ft}^{3}; 5}[/tex]
Step-by-step explanation:
1. Density
[tex]\begin{array}{rcl}\text{Density} & = & \dfrac{\text{Mass}}{\text{Volume}}\\\\& = & \dfrac{\text{4 lb}}{\text{10 ft}^{3}}\\\\& = &\textbf{0.4 lb/ft}^{\mathbf{3}}\\\end{array}\\\text{The density of the gas is $\large \boxed{\textbf{ 0.4 lb/ft}^{\mathbf{3}}}$}[/tex]
2. Specific gravity
Specific gravity (sp gr) is the ratio of the density of the density of a gas to the density of dry air at standard temperature and pressure.
At IUPAC standard temperature and pressure (0 °C and 100 kPa), dry air has a density of 0.080 lb/ft³.
[tex]\begin{array}{rcl}\text{Sp gr}& = & \dfrac{\rho_{\text{gas}}}{\rho_{\text{dry air}}}\\\\& = & \dfrac{\text{0.4 lb/ft}^{3}}{\text{0.080 lb/ft}^{3}}\\\\& = &\mathbf{5}\\\end{array}\\\text{The specific gravity of the gas is $\large \boxed{\mathbf{5}}$}[/tex]
The density is the ratio of mass to volume, while the specific gravity is the ratio of two densities
The values required are;
Density of the gas is 0.4 lb/ft.³The specific gravity of the gas is approximately 5.23Given:
Mass of the gas = 4 lb
Volume occupied by the gas = 10 ft.³
Required:
Find the density and the specific gravity of the gas
Density:
[tex]Density = \dfrac{Mass}{Volume}[/tex]
Therefore, the density of the mass of gas is given as follows;
[tex]Density = \dfrac{4 \ lb}{10 \ ft.^3} = 0.4 \ lb/ft.^3[/tex]
The density of the gas = 0.4 lb/ft.³
Specific gravity:
The specific gravity, s.g. of a gas is the ratio of the density of the gas to the density of air
The density of air ≈ 0.0765 lb/ft.³
The specific gravity of the gas is therefore;
[tex]s.g. = \dfrac{0.4 \ lb/ft.^3}{0.0765 \ lb/ft.^3} = \dfrac{800}{153} \approx 5.23[/tex]
The specific gravity of the gas is approximately 5.23
