Answer:

I believe its 20% thats counting the 10% shipping cost

Step-by-step explanation:

Final answer:

Kedwin needs a minimum sale rate of approximately 24.29% in order to afford the headphones.

Explanation:

To calculate the minimum sale rate that Kedwin needs to be able to afford the headphones, we first need to calculate the total cost of the headphones including shipping. The headphones cost $175.00 and the shipping is 10% of the cost, which is $17.50. So the total cost is $175.00 + $17.50 = $192.50.

Next, we subtract Kedwin's current funds, $150.00, from the total cost, $192.50, to find the amount he still needs, which is $192.50 - $150.00 = $42.50.

Finally, we divide the amount he still needs by the original cost of the headphones and multiply by 100 to find the minimum sale rate. In this case, the calculation is ($42.50 / $175.00) * 100 = 24.29%. Therefore, Kedwin needs a minimum sale rate of approximately 24.29% in order to afford the headphones.

Answer:

The two tires she bought is $35+$35 which then equals to $70. She spent $70 on tires. She then sold them for $65. She bought three rims, each $75... $75+$75+$75 which then equals her $225. And then sold them for $136. She then bought four headlight covers for $4 each... $4+$4+$4+$4, which equals her $16. Then sold them for $15. Her total profit is -$95. How i got that answer you say, well, if you calculate how much she spent on everything in total, she spent -$311 on everything.

Answer:

$720

Step-by-step explanation:

$1,200 divided by 2 (600) equals how many vanilla cupcakes there were.

40 people times 24 cupcakes each person (960) equals how many total cupcakes there were.

The total amount of cupcakes minus the amount of vanilla cupcakes equals the amount of chocolate cupcakes (960-600=360).

360 chocolate cupcakes times the amount each cupcake was sold for equals the amount of money raised from the chocolate cupcakes (360x2=720).

Answer:

544.5π cm³ ≈ 1711 cm³

Step-by-step explanation:

Each cylinder has a bore (diameter) of 11 cm, and stroke (height) of 6 cm.

V = πr²h

V = π (11 cm / 2)² (6 cm)

V = 181.5π cm³

There are 3 cylinders, so the total volume is:

3V = 544.5π cm³

3V ≈ 1711 cm³

To calculate the total stroke volume of an inline 3-cylinder engine with an 11 cm bore and a 6 cm stroke, calculate the area of the bore, find the volume of one cylinder by multiplying by the stroke, and then multiply by the number of cylinders. The total stroke volume of the engine is 1710.6 cm³.

The student asked to calculate the total stroke volume of an inline 3-cylinder engine with an 11 cm bore and a 6 cm stroke. The formula to calculate the volume of a single cylinder is V =  rac{ ext{ extpi}}{4}  imes D^2  imes S, where V is the volume, D is the diameter of the bore, and S is the stroke. In this case, D would be 11 cm, and we would need to square this value, then multiply by  extpi/4 and by the stroke length of 6 cm, then multiply the result by the number of cylinders, which is 3, to get the total engine displacement.

Step by step, we first calculate the area of the bore (cylinder base):
Area =  extpi  imes (radius)² =  extpi  imes (5.5 cm)²
=  extpi  imes 30.25 cm²
= 95.0332 cm². Next, we calculate the volume of one cylinder: Volume = Area  imes Stroke = 95.0332 cm²  imes 6 cm = 570.1992 cm³. Finally, we find the total volume for all three cylinders: Total Volume = 570.1992 cm³  imes 3
= 1710.5976 cm³. Thus, the total stroke volume of the engine is 1710.5976 cm³ or rounded to 1710.6 cm³.

Answer:

C

Step-by-step explanation:

We have a linear equation in the form  y = mx

Where m is the slope

The slope is the change in y divided by change in x.

We can take any 2 points on the line and see the change in y and divide it by the change in x. We will get slope, m.

Lets take points (2,3) and (6,9).

The change in y is 9 - 3 = 6

The change in x is 6 - 2 = 4

So, the slope would be:

m = 6/4 = 3/2 = 1.5

So, the equation would be:

y = 1.5x

Correct answer is C.

Answer:

6 ft

Step-by-step explanation:

Use the formula for area of a parallelogram A = bh

b is for base and h is for height. A is for area.

Substitute b for 8 1/4 ft² and A for 49 1/2 ft². Isolate "h" to find the height of the deck.

A = bh

49 1/2 ft² = (8 1/4 ft²)h    Divide both sides by 8 1/4 ft² to isolate h

(49 1/2 ft²) ÷ (8 1/4 ft²) = (8 1/4 ft²)h ÷ (8 1/4 ft²)

(49 1/2 ft²) ÷  (8 1/4 ft²) = h

h = 6ft

Therefore the height of the deck is 6 feet.

Answer:

1 compounding every 2 years

Step-by-step explanation:

Compounded bi-annually in mathematics refers to calculating interest twice a year, where the interest earned in the first six months is used to calculate the interest for the second six months.

The term compounded bi-annually refers to a method of calculating interest where the interest is added to the principal amount twice a year or every six months. This means that the interest you earn after the first six months will also earn interest for the second six months of the year. For example, if you have $1000 with an annual interest rate of 10% compounded bi-annually, after six months, you'd earn 5% interest of $50 making your total $1050. In the next six months, the interest would be calculated on $1050, giving you an another 5% of $52.5 for a total of $1102.5 for the year.

[tex]5\frac{1}{3}[/tex] liters is the amount to be drained out and replaced

Solution:

40 % antifreeze solution in 16 liter radiator

Let "x" be the amount drained from radiation and replaced with pure antifreeze

To obtain a 60 % antifreeze solution

The original solution is 16 liter, 40% of which is antifreeze

You want the solution to be 60% antifreeze:

60 % x 16 = [tex]\frac{60}{100} \times 16 = 9.6[/tex]

You will remove x liters of the 40% solution and replace it with x liters pure (100%) antifreeze.

[tex]40 \% (16 - x) + 100 \% \times x = 60 \% \times 16[/tex]

Let us solve expression for "x"

[tex]\frac{40}{100} \times (16 - x) + \frac{100}{100} \times x = \frac{60}{100} \times 16\\\\0.4(16-x) + x = 0.6 \times 16\\\\6.4 - 0.4x + x = 9.6\\\\6.4 + 0.6x = 9.6\\\\0.6x = 3.2\\\\x = 5.33\\\\x = 5\frac{1}{3}[/tex]

Thus [tex]5\frac{1}{3}[/tex] liters is the amount to be drained out and replaced

First solving for log5(92):

Solve for x:

x = 3^(log5(92)

x = 3^2.810

x = 21.903

The answer would be the first one.

A cell phone weighing 56 grams can be converted to kilograms by dividing by 1,000, resulting in a weight of 0.056 kilograms.

To convert the weight of a cell phone from grams to kilograms, one must utilize the metric system's conversion rate where 1 kilogram is equal to 1,000 grams.

Therefore, if a cell phone weighs 56 grams, to find the weight in kilograms, you would divide 56 by 1,000.

56 grams ÷ 1,000 = 0.056 kilograms.

Hence, the cell phone can weigh 0.056 kilograms.

It is important to note that in the metric system, expressing units in the most manageable form is advisable.

In this case, kilograms provide a more easily managed number for larger weights, whereas grams are suitable for smaller weights.

7x + 15x= 21x

Step-by-step explanation:

7x + 15x

= (7 + 15)x

= 22x

Answer: 22x

Step-by-step explanation: +7x and +15x are called terms and the numbers in front of the variables, +7 and +15 are called coefficients.

Because the variables, x and x, are identical, the two terms in this problem are called like terms. Like terms can be added together by simply adding their coefficients. So in this problem, since 7 + 15 is 22, 7x + 15x is simply 22x.

Answer:

Step-by-step explanation:

the first day he used 30 cups

the second day he used 15% of the remaining cups...a total of 90 cups were used on second day.

so 15%of the remaining cups = 90.....so if u let x be the total cups, then the remaining cups would be x - 30

15% of (x - 30) = 90.....turn ur percent to a decimal..." of " means multiply

0.15(x - 30) = 90

0.15x - 4.5 = 90

0.15x = 90 + 4.5

0.15x = 94.5

x = 94.5 / 0.15

x = 630 total cups <==

lets check..

start with 630 cups....used 30 the first day....leaving u with 600 cups....15% of the remaining cups = 90.....so 15% of 600 = 90....lets check it

15%of 600 = 0.15(600) = 90...yep, thats correct....there were 630 cups in the new un-opened box

Answer:

630

Explanation:

15% * number of remaining cups = 90

15% * (x-30) = 90

0.15(x-30) = 90

0.15x - 4.5 = 90

0.15x = 94.5

x = 630

Answer:

(- 2, 5 )

Step-by-step explanation:

Given the 2 equations

3x + 4y = 14 → (1)

x = 2y - 12 → (2)

Substitute x = 2y - 12 into (1)

3(2y - 12) + 4y = 14 ← distribute and simplify left side

6y - 36 + 4y = 14

10y - 36 = 14 ( add 36 to both sides )

10y = 50 ( divide both sides by 10 )

y = 5

Substitute y = 5 into (2) for corresponding value of x

x = 2(5) - 12 = 10 - 12 = - 2

Solution is (- 2, 5 )

To find the point that satisfies both equations, substitute the value of x from the second equation into the first equation and solve for y. Then substitute the value of y into the second equation to find x. The point (-2, 5) satisfies both equations.

To find the point that satisfies both equations, we need to solve the system of equations:

3x + 4y = 14

x = 2y - 12

Substituting the value of x from the second equation into the first equation, we get:

3(2y - 12) + 4y = 14

6y - 36 + 4y = 14

10y = 50

y = 5

Substituting the value of y into the second equation, we get:

x = 2(5) - 12

x = 10 - 12

x = -2

Therefore, the point (-2, 5) satisfies both equations.

given that line m, passes through (2,-7) and (4,-9)

(refer to attached)

slope of line m,

= [(-7) - (-9)] / (2- 4)

= (-7 +9) / (2- 4)

= (2) / (-2)

= -1

recall that the general form of a linear equation is

y = mx + b, where m is the gradient.

in this case, we found that m = -1, so look for the answer where the x-term has -1 as a coefficient, i.e the x-term is "-x"

By observation, we see that the only answer that has "-x" as part of the equation is A

The inverse variation function can be written as:

[tex]f(x)=\frac{-200}{x}[/tex]

Step-by-step explanation:

Given :

[tex]f(x)[/tex] varies inversely with [tex]x[/tex]

when [tex]x=20[/tex], [tex]f(x)=-10[/tex]

To find the inverse variation equation.

Solution:

[tex]f(x)[/tex] varies inversely with [tex]x[/tex] can be represented as:

[tex]f(x)[/tex] ∝ [tex]\frac{1}{x}[/tex]

Thus, [tex]f(x)=\frac{k}{x}[/tex]

where [tex]k[/tex] represents the constant of proportionality.

We can determine the value of [tex]k[/tex] by plugging in the values given.

when [tex]x=20[/tex], [tex]f(x)=-10[/tex]

So, we have

[tex]-10=\frac{k}{20}[/tex]

Multiplying both sides by 20.

[tex]20\times (-10)=20\times \frac{k}{20}[/tex]

[tex]-200=k[/tex]

Thus  the inverse variation function can be written as:

[tex]f(x)=\frac{-200}{x}[/tex]
