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?
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:

radius = diameter / 2
radius = 25.3/2
radius = 12.65 cm
Result radius = 12.65 cm
Would the answer be 2? I multiplied the coordinate (3, 6) by two and got ( 6, 12), I don't know if I'm right
Since we would need to multiply each coordinate by 1/2 to perform the transformation, then the scale factor would be 1/2. The answer is the first option.
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?
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:

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)
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.

The total commission earned by Paun is $14,000.
What is meant by the term commission?Full-service brokerages make the majority of their money by charging commissions on customer transactions.Commission-based advisors earn money by purchasing and selling a product on their clients' behalf.Commissions and fees differ in the financial services industry, where fees are a fixed amount for managing a customer's money.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.

use the data in the following table, which lists drive-thru order accuracy at popular fast food chains. Assume that orders are randomly selected from those included in the table. If two orders are selected, find the probability that they are both accurate. Complete parts (a) and (b) below.
a. Assume that the selections are made with replacement. Are the events independent?
The probability is __. The events __ (are, are not) independent.
(Do not round until the final answer. Round to four decimal places as needed.)
Answer:
a. If the selection is made with replacement, they are NOT independent because they affect each other.
b. The probability of selecting TWO accurate orders is .7157 and the events ARE independent.
Step-by-step explanation:
Add the accurate orders:
315+273+248+125=961
Add the inaccurate orders:
38+56+37+17=148
148/961=0.1540 probability of getting ONE inaccurate order
1.0-0.1540=0.846 probability of selecting ONE accurate order
0.846 * 0.846 = 0.7157 the probability of selecting TWO accurate orders
Therefore, the probability is .7157 and the events ARE independent.
g(x)=-3x-1 What is g(10
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
Hence "A function is a relation that gives one input for every one output thus the value of g(10) is -31".

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)

The projected profit (in thousands of dollars) in year t of a newly developed line of business can be modeled by the monomial t3 . Write a polynomial that models the company’s total profit including this new line of business.

a. The company will break even in 6 years
b. The total profit with the newly developed line of business is:
[tex]t^3+2t^2-9t-18[/tex]c. The company will break even 3 years sooner
Explanation:The projected profit is given as:
[tex]2t^2-9t-18[/tex]a. The company will break even when the profit is zero. That is;
[tex]\begin{gathered} 2t^2-9t-18=0 \\ \\ (2t+3)(t-6)=0 \\ 2t+3=0 \\ \Rightarrow t=-\frac{3}{2} \\ \\ t-6=0 \\ t=6 \end{gathered}[/tex]6 is the realistic number of years (As we cannot have -3/2 years).
We conclude that they will break even in 6 years
b. The projected profit of a newly developed line of business is:
[tex]t^3[/tex]The total profit is now;
[tex]t^3+2t^2-9t-18[/tex]The company will break even with this new line of business as follows:
[tex]\begin{gathered} t^3+2t^2-9t-18=0 \\ (t+2)(t+3)(t-3) \\ t+2=0 \\ \Rightarrow t=-2 \\ t+3=0 \\ \Rightarrow t=-3 \\ t-3=0 \\ \Rightarrow t=3 \end{gathered}[/tex]We choose t = 3 (because we cannot have -2 years or -3 years)
The difference between this and the previous time is 6 - 3 = 3 years
The company will break even 3 years sooner
