In San Francisco, the tax on a property with a $860,000 assessed value is $12900.
In Tacoma, the tax on a property assessed at $330,000 is $4,950.
The tax rates are proportional to this city.
Now, to find the tax on a property assessed at $860,000.
So, we need to determine the tax rate of Tacoma first.
Tax Rate = Tax / Property assessed × 100.
[tex]Tax {~}rate = \frac{4950}{330000} \times 100[/tex]
Tax rate = 0.015 × 100
Tax rate = 1.5%
From the question, the tax rates are proportional.
Now, we apply the same tax rate as Tacoma in this city:
Tax = tax rate of property assessed.
Tax = 1.5% of $860,000
[tex]Tax=\frac{1.5}{100} \times 860000[/tex]
Tax = 1.5 × 8600
Tax = $12900
Therefore, the tax on property in San Francisco assessed at $860,000 is $12900.

• Triangle B is a dilation of A with approximately what scale factor?
• Triangle A is a dilation of B with approximately what scale factor?
• Triangle B is a dilation of C with approximately what scale factor?
Answer:
Triangle B is a dilation of A with approximately what scale factor
Triangle B is a dilation of A with approximately a scale factor of 8.
Triangle A is a dilation of B with approximately a scale factor of 1/8.
Triangle B is a dilation of C with approximately a scale factor of 3/4.
We have,
In mathematics, dilation refers to the transformation of a shape, object, or figure by uniformly scaling it up or down.
When the constant factor is greater than 1, the dilation results in an enlargement of the shape, making it larger.
Conversely, when the constant factor is between 0 and 1, the dilation leads to a reduction of the shape, making it smaller.
Now,
Triangle B is a dilation of A with approximately by a scale factor of:
Since triangle B is greater than A.
The scale factor is greater than 1.
Triangle B looks 8 times of triangle A.
So,
The scale factor is 8.
And,
Triangle A is a dilation of B with approximately by a scale factor of:
Since triangle B is smaller than A.
The scale factor is less than 1.
Triangle A looks like 12.5 % of triangle C.
12.5% = 1/8
So,
The scale factor is 1/8.
Triangle B is a dilation of C with approximately by a scale factor of:
Since triangle B is smaller than A.
The scale factor is less than 1.
Let's say,
Triangle B looks 75% of triangle C.
So,
The scale factor is 3/4.
Thus,
Triangle B is a dilation of A with approximately a scale factor of 8.
Triangle A is a dilation of B with approximately a scale factor of 1/8.
Triangle B is a dilation of C with approximately a scale factor of 3/4.

a) Find the regression equation.
b) Predict the temperature at 2:00 p.m.
From the temperatures given, we have that:
a) The regression equation is: y = 2.91x + 64.61.
b) The predicted temperature at 2 pm is of 88 ºF.
How to find the equation of linear regression?To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator. These points are given on a table or in a scatter plot in the problem.
In the context of this problem, the input and the output are given as follows:
Input x: number of hours after 6 A.M.Output y: temperature.We have that an hour is 60 minutes, hence:
45 minutes = 0.75 hours.30 minutes = 0.5 hours.Thus the points are given as follows:
(0, 65), (0.75, 67), (1.5, 68), (2.5, 72), (3, 74), (3.75, 75), (4.5, 77), (5,80).
Inserting these points into the calculator, the equation is:
y = 2.91x + 64.61.
2 pm is 8 hours after 6 am, hence x = 8 and the predicted temperature, in ºF, is given by:
y = 2.91(8) + 64.61 = 88 ºF.

The rate of change of the linear function for the given table is determined as: C. 120.
What is a Linear Relationship Function?A linear relationship function is represented as a straight line graph which can be expressed as a linear equation in slope-intercept form as, y = mx + b.
The rate of change of the function is represented as m, which is also the slope of the graph, and the y-intercept is b.
How to Find the Rate of Change of a Function?A linear function has a rate of change/slope which can be found using the formula:
m = y2 - y1/x2 - x1.
Given the set of table values that represents a linear function below, we can use two pairs of values to find the rate of change as follows:
(0.5, 60) = (x1, y1)
(1.5, 180) = (x2, y2)
Plug in the values
Rate of change (m) = (180 - 60)/(1.5 - 0.5)
Rate of change (m) = (120)/(1)
Rate of change (m) = 120
Therefore, the rate of change of the linear function for the given table is determined as: C. 120.

8. A baseball is thrown from a height of 40 feet and goes up at a rate of 2.5 feet per second. A football is
thrown from a height of 25 feet and goes up at a rate of 3 feet per second. After how many seconds
would the two reach the same height?
The time taken depends upon velocity and distance so the time taken by both balls to reach the same height will be 30 seconds.
What is velocity?Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.
Units of velocity are given by ⇒ meter/second
For example, if a car drives 50 meters for 10 seconds and it is constant then 50/10 = 5 meters/second will be the velocity.
Difference between their initial height = 40 - 25 = 15 feet
It means if baseball cover x feet distance then football will cover x + 15 feet.
Now,
Time = distance covered / velocity
Since the time will be the same for both balls to meet them.
So,
Distance covered by baseball/velocity of baseball = Distance covered by football/ velocity of football
x/2.5 = (x + 15)/3
3x = 2.5x + 37.5
0.5x = 37.5
x = 75
So,
Time taken = 75/2.5 = 30 seconds.
Hence "After 30 seconds both balls will go to reach the same height".

25 percent of the original price was saved during the purchase of the futon bed
The percent of the original price that is saved can be calculated as follows
The original price is $700
The new price is $525
The first step is to calculate the percentage change
= 700-525
= 175
Therefore the percent saved can be calculated as follows
= 175/700 × 100

explain how you would round 25.691 to the greatest place
Answer:
In order to round 25.691 to the greatest place or the nearest whole number, first start at the last digit behind the decimal, in the case, being the 1. When it comes to things like this, if the digit is 4&under meaning its the number 4,3,2,1 or 0. If it is 5&up, that means it could be 5-9, making the digit go up (but if its 2, then the digit just goes away, you wont have to worry about that one specific number).
Next step is to round the 9 which makes the 6 go up one digit (meaning it turns into a 7). Now, when you round the seven, it will make the whole number go up one digit, but if you want to round that as well, to start, it's first rounding equaled up to 26. If you're rounding it to a whole tens number, it would be 30. I hope that this helps you understand this subject or topic much better! :3

2x−3y=−5 4x−4y=−4 Is (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis a solution of the system?
(2,3) is a solution to the system of equations.
A collection of one or more linear equations containing the same variables is known as a system of linear equations (or linear system).
Consider the system of equations,
2x - 3y = - 5 --------(1)
4x - 4y = - 4 --------(2)
Multiplying equation (1) with 2.
4x - 6y = - 10
4x - 4y = - 4
Now, subtracting the above equations:
4x - 6y - ( 4x - 4y) = - 10 + 4
4x - 6y - 4x + 4y = - 6
- 2y = - 6
2y = 6
y = 3
Then,
4x - 4y = - 4
4x - 4 × 3 = - 4
4x - 12 = - 4
Adding 12 on both sides of the equation,
4x - 12 + 12 = - 4 + 12
4x = 8
x = ( 8/4 )
x = 2

How to resolve a system of equation by algebra methods
Herein we find a system formed by one linear equation and one nonlinear equation (quadratic equation). First, we equalize the two equations to eliminate the variable y:
2 · x² - 5 · x - 7 = 2 · x + 2
2 · x² - 7 · x - 9 = 0
2 · [x² - (7 / 2) · x - 9 / 2] = 0
2 · (x - 9 / 2) · (x + 1)
There are two solutions to x: x₁ = 9 / 2, x₂ = - 1. And the solutions for y are:
x₁ = 9 / 2y₁ = 2 · (9 / 2) + 2
y₁ = 11
