Last week, Lisa sold 20 hand-engraved watch bands, earning a total profit of $105.00.She plans to make 50 engraved watch bands to sell at the community art fair. If shesells all 50 watch bands, how much profit can Lisa expect to earn?

Answers

In this case, we'll have to carry out several steps to find the solution.

Step 01:

data:

hand-engraved watch bands:

total watch bands = 20

total profit = $105.00

Step 02:

ratio:

total profit (50 watch bands):

[tex]50\text{ watch bands * }\frac{\text{ \$ 105.00}}{20\text{ watch bands}}\text{ = \$ 262.50 }[/tex]

The answer is:

$ 262.50

The Smith’s and the Jones are neighbors. They both have a tax rate of 28.5 mills. The Smith’s house is assessed at $80,000. The Jones’ house is assessed at $67,000. How much more do the Smith’s pay in property tax?

Answers

Given

Tax rate = 28.5 mills

Smith's house is accessed at $80,000

Jones's house is accessed at $67,000

Property taxes are calculated by multiplying the assessed, taxable property value by the mill rate and then dividing that sum by 1,000.

The formula is given by:

[tex]Property\text{ tax levied on property = }\frac{mill\text{ rate }\times taxable\text{ property value}}{1000}[/tex]

Property tax for the Smith's:

[tex]\begin{gathered} =\text{ }\frac{28.5\text{ }\times\text{ 80000}}{1000} \\ =\text{ 2280} \end{gathered}[/tex]

Property tax for the Jones':

[tex]\begin{gathered} =\frac{28.5\text{ }\times\text{ 67000}}{1000} \\ =\text{ 1909.5} \end{gathered}[/tex]

The extra amount the Smith's pay is the difference in the tax levied on Smith and Jones:

[tex]\begin{gathered} =\text{ 2280 - 1909.5} \\ =\text{ 370.5} \end{gathered}[/tex]

Hence, the Smith's pay $370.5 more than the Jones'

For the given question.

The total sales done by Paun is $50,000.

There is commission of 25% on first $2000.

There is commission of 30% on remaining that is 48,000.

The total commission will be 25% of $2,000 and 30% of 48,000.

25% of $2,000 = 25 × 2000/100

25% of $2,000 = $500

30% of 48,000 = 30 × 48,000/100

30% of 48,000 = $14,400

Total commission = $500 + $14,400 = $14,900.

Thus, the total commission earned by Paun is $14,000.

Using the discriminant of a quadratic function, it is found that:

6. The range of values is of c ≤ 1/16.

8. The range of values of k is: -9 < k < -1.

10. The discriminant is never negative, hence the function has real roots for all values of k.

Discriminant of a quadratic function

A quadratic function is modeled as follows:

y = ax² + bx + c.

The discriminant of the function is given as follows:

Δ = b² - 4ac

For item 6, the function is given as follows:

y = 2x² - 3x + (2c + 1).

The coefficients are given as follows:

a = 2, b = -3, c = 2c + 1.

The function is positive for all values of x if it has at most one real root, hence:

Δ ≥ 0

(-3)² - 4(2)(2c + 1) ≥ 0

9 - 16c - 8 ≥ 0

1 - 16c ≥ 0

16c ≤ 1

c ≤ 1/16

For item 8, the function is given as follows:

y = kx² - (k - 3)x - 1 = 0.

The coefficients are given as follows:

a = k, b = -k - 3, c = -1.

It has no real roots if:

Δ < 0

b² - 4ac < 0

(-k - 3)² - 4(k)(-1) < 0

k² + 6x + 9 + 4k < 0

k² + 10k + 9 < 0

Hence the range is:

-9 < k < -1.

For item 10, the function is given as follows:

y = kx² + (k - 2)x - 2 = 0.

The coefficients are given as follows:

a = k, b = k - 2, c = -2.

It has no real roots if:

Δ < 0

b² - 4ac < 0

(k - 2)² - 4(k)(-2) < 0

k² - 4k + 4 + 8k < 0

k² + 4k + 4 < 0

(k + 2)² < 0.

(k + 2)² is always positive, hence the function will always have real roots.

Answer

[tex]\begin{gathered} D. \\ 5x+4=4x+7 \\ \text{The number is 3} \end{gathered}[/tex]

Explanation

The variable given is x

Five times the variable is 5x

When 4 is added, the expression becomes 5x + 4, which gives the Left Hand Side of the equation.

For the Right Hand Side, four times the number is 4x

7 more than 4x is 4x + 7

Since the result on the Left Hand Side = Right Hand Side, then the required equation is

[tex]5x+4=4x+7[/tex]

Now, to find the number x, we shall solve the above equation as follows

Add the inaccurate orders:

The amount of flour needed for 72 cookies is 4.5 cups.

46 / 69 and 48/84 are not proportional because the fractions in their simplest forms are 3/4 and 4/7.

The value of x in  2/3 = 1.2 / x is 1.8.

The value of x in 8 / 15 = 24 / x is 45.

7 / 5 ≠ 15 / 10.

6 / 8 = 15/20

What are the solutions?

In order to determine how many cups of flour is needed for 72  cookies, determine how many cups is needed for one cookies.

Amount of flour needed for one cookie = 3/48

Now, multiply this fraction by 72: 3/48 x 72 = 4.5 cups

If two fractions are proportional, when they are expressed in their simplest form, both fractions would have equal values.

46 / 69 = 2 / 3

48 / 84 = 4/7

Given this equation : 2/3 = 1.2 / x

In order to determine the value of x, cross multiply:

2x = 3 x 1.2

2x = 3.6

x = 3.6 / 2

x = 1.8

Given this equation : 8 / 15 = 24 / x

In order to determine the value of x, cross multiply:

8x = 24 x 15

8x = 360

x = 360 / 8

x = 45

7/5 and 15 / 10

7/5 =  15 /10

The cross product:

(7 x 10) = (5 x 15)

70 ≠ 75

6 / 8 = 15/20

The cross product : (6 x 20) = (8 x 15)

A function is a relation that gives one input for every one output thus the value of g(10) is -31.

What is a function?

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given function,

g(x) = -3x - 1

The value of the function at x = 10

g(10) = -3(10) - 1

g(10) = -30 - 1 = -31

A Native American tepee is a conical tent. Find the number of skins needed to cover a teepee 10 ft. in diameter and 12 ft. high. Each skin covers 15 sq. ft. (use = 3.14)

Answers

Since it is conical, we need to find the surface area of the top of the conical shape.

If we unfold the top part of the cone, we will have a section of a circle:

The circunference of this section is the same as the total circunference of the base of the cone, which we can get from its radius (half its diamtere):

[tex]C=2\pi r=2\pi\cdot\frac{D}{2}=2\pi\cdot\frac{10}{2}=10\pi[/tex]

If we visualize the cone by the side, we see that it forms a isosceles triangle which the same height and the base euqal to the diameter:

So, we can calculate "R", the radius of the unfolded cone, using the Pythagora's Theorem:

[tex]\begin{gathered} R^2=h^2+(\frac{D}{2})^2 \\ R^2=12^2+5^2 \\ R^2=144+25 \\ R^2=169 \\ R=\sqrt[]{169} \\ R=13 \end{gathered}[/tex]

The circunference of a section of a circle is the circunferece of the total circle times the fraction of the section represents of the total circle. Let's call ths fraction "f", this means that:

[tex]\begin{gathered} C_{total}=f\cdot C \\ C_{total}=2\pi R=2\pi\cdot13=26\pi \\ C=10\pi \\ f\cdot26\pi=10\pi \\ f=\frac{10\pi}{26\pi}=\frac{5}{13} \end{gathered}[/tex]

The area will follow the same, the area of the section is the fraction "f" times the total area of the circle, so:

[tex]\begin{gathered} A_{total}=\pi R^2=\pi13^2=169\pi \\ A=f\cdot A_{total}=\frac{5}{13}\cdot169\pi=65\pi\approx65\cdot3.14=204.1 \end{gathered}[/tex]

So, the surface area of the top of the cone is 204.1 ft². Since each skin covers 15 ft², we can calculate how many skins we need by dividing the total by the area of each skin:

[tex]\frac{204.1}{15}=13.60666\ldots[/tex]

This means that we need 13.60666... skins, that is, 13 is not enough, we need one more, so we need a total of 14 skins.
