Answer with a complete sentence. Eric and Jan leave their house at one o-clock, following the same route. Jan walks at a steady pace of 4 mph. Eric walks at a leisurely 2 mph for 2 hours, and then jogs at 6 mph. When will he catch up with her?
Answer:
4h = 4 + 6(h - 2)
4h = 4 + 6h - 12
4h = 6h - 8
2h = 8
h = 4 hours
Eric will catch up with Jan at 5:00.

A friend asks to borrow $250 for 18 months and agrees to pay 12% annual simple interest. How much interest will you
earn?
Round your answer to the nearest dollar.
Provide your answer below:
Answer:
$90 of interest will be earned.
Step-by-step explanation:
We are given the following in the question:
Principal,P = $250
Time, T = 18 months = 3 years
Rate, R = 12% = 0.12
Formula for simple interest:
[tex]I =\dfrac{P\times R\times T}{100}[/tex]
Putting values, we get,
[tex]I =\dfrac{250\times 12\times 3}{100} = \$90[/tex]
Thus, interest of $90 will be earned.
You spend $62 on a game, receive $50 for painting a fence, and give $10 to your friend. You have $44 left.
How much money did you start with?
Answer:
You started with $66.
Step-by-step explanation:
The equation would be:
[tex]x-62+50-10=44\\ x-22=44\\ x=66\\[/tex]
To check the answer:
[tex]66-62+50-10=44\\4+50-10=44\\54-10=44\\44=44[/tex]
We started with $66 initially.
What is Algebra?Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. It tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.
As per the given data:
Money spend on game (g) = $62
Money received for painting a fence (p) = $50
Money given to friend (f) = $10
Money left = $44
To find out the money we had initially:
Let's assume we had $x.
Money left = x - g + p - f
44 = x - 62 + 50 - 10
44 = x - 22
x = $66
Hence, We started with $66 initially.

Given f(n) is a geometric sequence where f(3)=32 and f(9)=72, find f(16).
I think the answer may be 64/27, but I don't know for sure.
Answer:
f(16)=162
Step-by-step explanation:
-In a geometric sequence, the quotient between any tow consecutive numbers is called the common ratio,r:
[tex]r=\frac{a_n}{a_{n-1}}[/tex]
Given that f(3)=32 and f(9)=72, we can find the common ratio as below:
[tex]r=\frac{a_n}{a_{n-1}}\\\\\therefore \frac{f(9)}{f(3)}=r^6\\\\\frac{72}{32}=r^6\\\\r^6=2.25\\\\r=2.25^{1/6}[/tex]
#We substitute and use the same formula to find the nth term:
[tex]a_n=ar^{n-1}[/tex]
let f(3) be a(the first term):
[tex]a_n=ar^{n-1}\\\\a_{16}=32(2.25^{1/6})^{16-3-1}\\\\a_{16}=32(2.25^{1/6})^{12}\\\\\\=162[/tex]
Hence, f(16)=162

On a separate sheet of paper graph the following function. In the answer box describe the function.
f(x) = 2[x] – 3
Answer:
Answer
Step-by-step explanation:
The function is a greatest integer function, which is a step function.
The function f(x) = 2[x] - 3 features a step-like graph due to the floor function [x]. To graph it, calculate f(x) for integer values, plot the points, and draw horizontal lines between them. The function's range in this context is specified to be between 0 and 20.
Explanation:The function given is f(x) = 2[x] - 3, where [x] denotes the greatest integer function, also known as the 'floor' function, which returns the greatest integer less than or equal to x. This type of function creates a step-like graph. When graphing this function, you'll notice that for every integer value of x, the function will take on a constant value until the next integer is reached, at which point it will jump up to the next 'step'.
To graph this function, you should first calculate the values of f(x) at various integer points within the given range. Then plot these points on a coordinate plane and create horizontal lines to represent the function's value between each pair of consecutive integer x values. For non-integer values of x, the function value will be based on the floor of x. Label your graph with f(x) and x. Make sure to scale the x and y axes with the maximum values, considering that in this case we are dealing with 0 ≤ x ≤ 20.

The unit price for installation per square foot of tile is
Answer:
the tile is 4.50 per square foot to install
it will cost 3780.00 to install 840 square feet
Step-by-step explanation:
divide 607.50 by 135 to find out the price per square foot to install
multiply the price per square foot by the number of square feet you are installing so 4.50 X 840

A zip line starts 28 feet in the air and
ends 11 feet in the air. The zip line drops
at an angle of 85 degrees 85°. How long
is the zip line cable when completely
taut (no rider)?
Given:
A zip line goes from 28 feet to 11 feet in the air. The angle of depression is 85°.
To find:
The length of the zip line where there is no rider.
Solution:
A right-angled triangle can be formed using the given data.
The difference in height between the start and end of the zipline is [tex]28-11=17[/tex]. The angle of the triangle is 85°.
Assume the zip line is x feet long.
The adjacent side of the triangle measures 17 feet, the hypotenuse of the triangle measures x feet, and the angle of the triangle is 85°.
To determine x, we calculate the cos of the given angle.
[tex]cos \theta = \frac{adjacentside}{hypotenuse} .[/tex]
[tex]cos 85 = \frac{17}{x} , x = \frac{17}{cos85}, cos85= 0.0871.[/tex]
[tex]x = \frac{17}{0.0871} = 195.1779.[/tex]
Rounding this off, we get the length of the zip line when there is no rider is 195.18 feet long.
The length of the zip line when there is no rider is 195.18 feet long.
Calculation of the length of the zip line:Here the difference is
= 28 - 11
=17
And, The angle of the triangle is 85°.
Here we Assume the zip line should be x feet long.
Now
The length should be
[tex]cos\ 85 = 17\div x\\\\x = 17\div 0.0871[/tex]
= 195.18
Hence, The length of the zip line when there is no rider is 195.18 feet long.

Final answer:
To factor the quadratic expressions, we look for pairs of numbers that multiply to give the constant term and add to give the coefficient of the middle term, resulting in the expressions (x - 9)(x - 5) for the first and (n + 8)(n - 4) for the second.
Explanation:
The question relates to factoring quadratic expressions, which is a fundamental skill in algebra. Specifically, we are looking to factor the expressions [tex]x^2[/tex] - 14x + 45 and [tex]n^2[/tex] + 4n - 32 completely. Factoring involves finding two binomial expressions that multiply together to give the original quadratic expression.
To factor [tex]x^2[/tex] - 14x + 45, consider two numbers that multiply to 45 and add to -14. These numbers are -9 and -5. Therefore, the factored form is (x - 9)(x - 5).
To factor [tex]n^2[/tex] + 4n - 32, we again look for two numbers that multiply to -32 and add to 4. These numbers are 8 and -4. Thus, the factored form is (n + 8)(n - 4).
