A real estate broker sold your house for $189,000. The broker's commission was 4.5 percent of the selling price. How much would you get for the house after the commission is paid?

Answers

First, we are going to find the commission of the broker. To do that we are going to multiply the selling price of your house by 4.5 percent:
[tex]189000*[/tex]4.5%=[tex]189000* \frac{4.5}{100}=8505 [/tex]

Next we are going to subtract the broker's commission ($8505) from the selling price of your house:
[tex]189000-8505=180495[/tex]

We can conclude that you will get $180,495 from your house after the commission is paid.

if a horse weighs 500kg and a spider 1g how many spiders weigh the same as one horse??

Answers

Hello!

First you have to put the horses weight into grams

There are 1000 kilograms in a gram

Multiply the horse weight by 1000 to get its weight in grams

500 * 1000 = 500000g

Divide the weight of the horse by the weight of the spider

500000 / 1 = 500000

The answer is 500,000 spiders

Diana uses 30 grams of coffee beans to make 48 fluid ounces of coffee. How many grams of coffee beans foes Diana uses when company comes?

Answers

The question uses proportional reasoning to determine the quantity of coffee beans Diana would need to make a different volume of coffee. By setting up a ratio based on the original 30 grams for 48 fluid ounces, we can calculate the necessary amount of coffee beans for any new volume of coffee required which is 60 grams.

The question relates to proportion and unit conversion, both key concepts in mathematics, specifically in dealing with ratios and measurements. Diana uses 30 grams of coffee beans to make 48 fluid ounces of coffee. If 'company comes' and she needs to make more or less coffee, the same ratio of coffee beans to water would apply. To determine the amount of coffee beans Diana would need for a different volume of coffee, you would set up a proportion based on the given ratio and solve for the unknown quantity.

To calculate the amount of coffee beans for a new volume, you can use the following steps:

Determine the new volume of coffee in fluid ounces.

Set up a ratio comparing 30 grams of coffee beans to 48 fluid ounces.

Use the new volume in the ratio to solve for the amount of coffee beans required.

For example, if Diana wants to make 96 fluid ounces of coffee for her company, the proportion would be:

30 grams / 48 fluid ounces = X grams / 96 fluid ounces

Solving this gives us X = (30 grams * 96 fluid ounces) / 48 fluid ounces = 60 grams. Hence, Diana would need 60 grams of coffee beans for 96 fluid ounces of coffee.

The points in the graph that will intersecr in the x axis would be 0. It has no points since it just involves a y axis line and ita pointa do not pass in the x axis. So the best and most correct answer is B. 0.

The nature of roots can help us to determine the answer to this question and discriminant can be used to determine the nature of the roots.

Discriminant = b² - 4ac

b = coefficient of x term = -9
a = coefficient of squared term = 4
c = constant term = 9

So, Discriminant = 81 - 4(4)(9) = -63

Since, the discriminant is negative, the equation will have complex zeros.This means its graph will not cross x-axis at any point.

So, the answer to this question is zero, option B

A certain country's postal service currently uses 6-digit zip codes in most areas. how many zip codes are possible if there are no restrictions on the digits used? how many would be possible if the first number could not be 0?

Answers

If any digit can be 0 to 9 with no restrictions, the number of possible zip codes is ...
10×10×10×10×10×10 = 10⁶ = 1,000,000.

Final answer:

For a 6-digit zip code with no restrictions, there would be 1,000,000 possible zip codes. If the first digit could not be a '0', the number of possible zip codes would decrease to 900,000.

Explanation:

We're dealing with a counting problem here. This problem involves basic principles of combinatorics.

Firstly, if there are no restrictions on the digits used, each of the six positions in the zip code can hold any digit from 0 to 9. There are 10 choices (from 0 to 9) for each of the 6 digits in the zip code which leads to 10^6 = 1,000,000 possible zip codes.

However, if the first number could not be 0, there are 9 possible choices for the first digit and 10 choices for each of the remaining 5 digits. Therefore, the number of possible zip codes would be 9 * 10^5 = 900,000.

and

[tex]y = \frac{1}{2} x - 3...(2)[/tex]

Add equations (1) and (2) to get,

We put y=½ into equation (2) to get,

[tex] \frac{1}{2} = \frac{1}{2} x - 3[/tex]

Find (tan A+B) if A and B are in quadrant 2 with tan A=(1/3) and sin B=(20/29)

Answers

Final answer:

The value of [tex]$ \tan(A + B) $[/tex] in quadrant 2, where [tex]$ \tan A = \frac{1}{3} $[/tex] and [tex]$ \sin B = \frac{20}{29} $[/tex], is [tex]$ \frac{11}{57} $[/tex].

Explanation:

To find [tex]$ \tan(A + B) $[/tex], we can use the formula [tex]$ \tan(A + B) = \frac{\tan A + \tan B}{1 - \tan A \tan B} $[/tex]. Given that \[tex]( \tan A = \frac{1}{3} \)[/tex] and [tex]$ \sin B = \frac{20}{29} $[/tex], we can determine [tex]$ \cos B $[/tex] using the fact that [tex]$ \sin^2 B + \cos^2 B = 1 $[/tex]. Therefore, [tex]$ \cos B = \sqrt{1 - \sin^2 B} = \frac{21}{29} $[/tex].

Now, substitute the values into the formula for [tex]$ \tan(A + B) $[/tex]:

[tex]\[ \tan(A + B) = \frac{\tan A + \tan B}{1 - \tan A \tan B} \][/tex]

[tex]\[ = \frac{\frac{1}{3} + \frac{20}{29}}{1 - \frac{1}{3} \cdot \frac{20}{29}} \][/tex]

[tex]\[ = \frac{\frac{29 + 60}{87}}{\frac{87 - 20}{87}} \][/tex]

[tex]\[ = \frac{\frac{89}{87}}{\frac{67}{87}} \][/tex]

[tex]\[ = \frac{89}{67} \][/tex]

Therefore, [tex]$ \tan(A + B) = \frac{11}{57} $[/tex] in quadrant 2.

Final answer:

To find (tan A+B) when A and B are in quadrant 2, find the components of A and B along the x- and y-axes using A = 34.0 m, θA = 63.0°. Calculate Ax = A cos θA and Ay = A sin θA. Then use the formula tan(A + B) = (tan A + tan B) / (1 - tan A tan B) to find the sum of the tangents.

Explanation:

First, we find the components of A and B along the x- and y-axes. From the problem, we know that A = B = 34.0 m, and θB = 63.0°. We find the x-components by using Ax = A cos θ, which gives Ax = 34.0 cos 63.0° = -15.23 m.

Similarly, we find the y-components by using Ay = A sin θ, which gives Ay = 34.0 sin 63.0° = 29.88 m.

Now, we can find the sum of the tangents of A and B using the formula tan(A + B) = (tan A + tan B) / (1 - tan A tan B). Substituting the given values, we have tan(A + B) = (1/3 + Ay/Ax) / (1 - (1/3)(Ay/Ax)).

It costs $0.05 to send a text message and $0.10 to send a picture on your cell phone. You spend $4 and send five more text messages than pictures. How many text messages, x, and pictures, y, did you send?

Answers

The first thing we must do for this case is to define variables:
x: text messages
Y: pictures
We write the system of equations:
0.05x + 0.10y = 4
x = y + 5
Solving the system we have:
x = 30
y = 25
Answer:
you send:
30 text messages
25 pictures

Final answer:

This is a problem of system of linear equations. We form two equations from the conditions given in the problem, and solve the system of equations to find the number of text messages and pictures sent.

Explanation:

This is a problem of system of linear equations. Here are two conditions mentioned: The total cost and difference of number of text messages and pictures.

Let's denote the number of text messages as x and pictures as y as per your question.

From the cost, we have the equation: $0.05x + $0.10y = $4.

From the difference of the number of sent messages and pictures, we have: x = y + 5.

Now we can substitute x from the second equation into the first one, get the value for y, and calculate the value for x after. Here you have step-by-step solution for your problem.

The exponential function represented by the table can be written in the form y=ab^x. Find the values for a and b.

Answers

If this function can be written in the form y = ab^x, then we see that when x is inputted as 0, y is outputted as 4. This means that
                                          4 = ab^0
                                          a = 4
The value of a is 4.
We see that when x = 1, y = 2 thus
                                           y = 4b^x
                                          2 = 4(b^1)
