In Tacoma, the tax on a property assessed at $330,000 is $4,950. If the tax rates in San Francisco are proportional to Tacoma, how much would the tax be on a property assessed at $860,000?
The tax on a property in San Francisco with an assessed value of $860,000 will be $
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.

The domain of this graph is equal to (-1, 4).The range of this graph is equal to (-2, 3).The function which this graph represents is a discrete function.How to identify the range and domain of this graph?The vertical extent of a graph represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.
Similarly, the horizontal extent of a graph represents all domain values and they are also read and written from smaller to larger numerical values, and from the left of the graph to the right.
By critically observing the graph of the discrete function shown, we can infer and logically deduce the following:
Domain = (-1, 4).Range = (-2, 3).In conclusion, the function which this graph represents is a discrete function because both the domain and range have discrete set of values, rather than intervals.

by 7.2°F. Between 3pm and 6pm, the temperature dropped 15.5°F. What was the
temperature at 6pm?
By using basic arithematic operations we concluded that the temperature at 6 pm was - 9.8°F.
What are fundamental arithematic operations?Arithmetic operation is the study of numbers and the operations on numbers that are used in all other branches of mathematics. It primarily consists of basic operations like addition, subtraction, multiplication, and division.
The temperature at 09:00 am = -6.9°F.
The tempertaure increased by 5.4°F till noon
So, the final tempertaure at noon = - 6.9°F + 5.4°F
= - 1.5°F
Then, again the temperature increased by 7.2°F from noon till 3 pm.
So, the final tempertaure at 3 pm = - 1.5°F + 7.2°F
= 5.7°F
Then, again the temperature by dropped 15.5°F from 3 pm to 6 pm.
So, the final tempertaure at 6 pm = 5.7°F - 15.5°F

A store is having a sale on walnuts and chocolate chips. For 4 pounds of walnuts and 8 pounds of chocolate chips, the total cost is 21$. For 2 pounds of walnuts and 3 pounds of chocolate chips, the total cost is $9. Find the cost for each pound of walnuts and each pound of chocolate chips.
The cost for each pound of walnuts is $ 2.25 and each pound of chocolate chips is $ 1.5.
We are given that:
Cost of 4 pounds of walnuts and 8 pounds of chocolate chips = $ 21.
Cost of 2 pounds of walnuts and 3 pounds of chocolate chips = $ 9.
Let the cost of pounds of walnuts be x and the cost of pounds of chocolate chips be y.
So, we get the following equations:
4 x + 8 y = 21 …(1)
2 x + 3 y = 9
2 x = 9 - 3 y
x = 1 / 2 (9 - 3y) …(2)
Put the value of x in (1)
4 ( 1 / 2 (9 - 3y) ) + 8 y = 21
2(9 - 3y) + 8 y = 21
18 - 6 y + 8 y = 21
2 y + 18 = 21
2 y = 21 - 18
2 y = 3
y = 3 / 2
y = 1.5
x = 1 / 2 (9 - 3y)
x = 1 / 2 ( 9 - 4.5)
x = 1 / 2 ( 4.5)
x = 2.25
Therefore, we get that, the cost for each pound of walnuts is $ 2.25 and each pound of chocolate chips is $ 1.5.

What are linear equation in one variables?The basic equation used to represent and solve for an unknown quantity is a linear equation in one variable. It is always a straight line and can be represented graphically. A linear equation is a straightforward way of representing a mathematical statement. Unknown quantities can be represented by any variable or symbol, but in most cases, in a linear equation with one variable, a variable 'x' is used to represent the unknown quantity.
No. of sales =18.9476+1.1842x
Here x = no. of phone calls
The agent calls 20 client.
So, x = 20
Put x = 20 in the given no. of sales. equation
No. of sales = 18.9476 + (1.1842)(20)
No. of sales = 18.9476+23.684
No. of sales = 42.6316
Since the number of sales can't be in decimal numbers, so we will round off the given no. of sales.

These are the first sentences in the short story, "The Gift of the Magi," by O. Henry:
"One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies."
Model the scenario with an equation. Let q be the number of quarters, d be the number of dimes, and n be the number of nickels.
25 q + 10 d + 5 n + 60 = 1.87
0.25 q + 0.10 d + 0.5 n + 0.60 = 187
q + d + n + 60 = 187
25 q + 10 d + 5 n + 60 = 187
Answer:
25 q + 10 d + 5 n + 60 = 187
Step-by-step explanation:
$1.87 = 1.87 x 100 = 187 cents or 187 pennies
Each quarter is worth 25 pennies so q quarters = 25q pennies
Each dime is worth 10 pennies so d dimes = 10d pennies
Each nickel is worth 5 pennies so n nickels = 5n pennies
so 25q + 10d + 5n + 60 = 187

Answer:
The maximum number of people that can be invited is 65.
Step-by-step explanation:
Based on the information given in the question, the equation to solve the question will be:
80 + 37x = 2500
80+37x=2500
Step 1: Simplify both sides of the equation.
37x+80=2500
Step 2: Subtract 80 from both sides.
37x+80−80=2500−80
37x=2420
Step 3: Divide both sides by 37.
37x/37 = 2420/37
x= 2420/37
x = 65.4
