You invested some money in a start-up company, and now your investment has gained 60% and is worth $6,720. how much was your original investment?
Your original investment in a start-up company was $4200
Let you invested x dollars in a start-up company.
Now your investment has gained 60% and is worth $6,720.
We write above statement as a mathematical expression.
From given information, x + (60 percent of x) = 6720
So we get an equation,
x + (0.6 x) = 6720
We solve above equation for x.
1.6 x = 6720
x = 6720 / 1.6
x = 4200 dollars
This means, initially you invested $4,200
Therefore, your original investment in a start-up company was $4200

zoe walks from her house to a bus stop that is 460 yards away. as zoe's distance from her house increases from 50 yards to 210 yards, her distance from the bus stop varies from incorrect yards to 250 correct yards.
Zoe travels 380 yards on foot from her home to the bus station. The distance between Zoe's home and the bus stop fluctuates from 250 yards to 410 yards when her distance from her home rises from 50 yards to 210 yards.
What is distance?Distance is the measurement of the separation between two points. Since distance is a scalar quantity, it solely cares about its measurement or amount. Distance is measured and often stated in terms of meters in SI units (m).
Given,
zoe walks from her house to a bus stop that is 460 yards
and zoe's distance from her house increases from 50 yards to 210 yards,
So,
d1 = 460 yards - 50 yards
= 410 yards
d2 = 460 yards - 210 yards

[tex]\textsf{3.} \quad h(x)+g(x)= 4x^2-x+5[/tex]
[tex]\textsf{4.} \quad h(x)-f(x)= -4x^2-3x+2[/tex]
[tex]\textsf{5.} \quad g(2)+f(x)= 4x^2+23[/tex]
Step-by-step explanation:
Given functions:
[tex]\begin{cases}f(x)=4x^2+2\\g(x)=4x^2+2x+1\\h(x)=-3x+4\end{cases}[/tex]
Function composition is an operation that takes two functions and produces a third function.
Question 1
Add function f(x) and function g(x) together:
[tex]\begin{aligned} \implies f(x)+g(x) & = (4x^2+2)+(4x^2+2x+1)\\& = 4x^2+2+4x^2+2x+1\\& = 4x^2+4x^2+2x+2+1\\& =8x^2+2x+3\end{aligned}[/tex]
Question 2
Subtract function g(x) from function f(x):
[tex]\begin{aligned} \implies f(x)-g(x) & = (4x^2+2)-(4x^2+2x+1)\\& = 4x^2+2-4x^2-2x-1\\& = 4x^2-4x^2-2x+2-1\\& =-2x+1\end{aligned}[/tex]
Question 3
Add function h(x) and function g(x) together:
[tex]\begin{aligned} \implies h(x)+g(x) & = (-3x+4)+(4x^2+2x+1)\\& = -3x+4+4x^2+2x+1\\& = 4x^2-3x+2x+4+1\\& = 4x^2-x+5\end{aligned}[/tex]
Question 4
Subtract function f(x) from function h(x):
[tex]\begin{aligned} \implies h(x)-f(x) & = (-3x+4)-(4x^2+2)\\ & = -3x+4-4x^2-2\\ & = -4x^2-3x+4-2\\ & = -4x^2-3x+2\end{aligned}[/tex]
Question 5
Add function g(x) when x = 2 to function f(x):
[tex]\begin{aligned} \implies g(2)+f(x) & = \left(4(2)^2+2(2)+1\right)+(4x^2+2)\\& = 4(4)+2(2)+1+4x^2+2\\& = 16+4+1+4x^2+2\\& = 4x^2+16+4+1+2\\& = 4x^2+23\end{aligned}[/tex]

The solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.
What are the solutions to the given equation?Given the equation in question;
|3x-7| - 7 = x
First, add 7 to both sides.
|3x-7| - 7 + 7 = x + 7
|3x-7| = x + 7
Next, remove the absolute value term, this creates a ± on the right side of the question.
|3x-7| = x + 7
3x-7 = ±( x + 7 )
The complete solution is the result of both the negative and positive portions of the solution.
For the first solution, use the positive of ±.
3x-7 = ( x + 7 )
3x - 7 = x + 7
3x - x = 7 + 7
2x = 14

How to Do Long Division with Decimals
If the number you're dividing by has a decimal, move the decimal point all the way to the right counting the number of places you've moved it to. Then move the decimal point in the number you're dividing the same number of places to the right.
Insert a decimal point in the quotient (answer) space, exactly above the decimal point in the number under the division bar.
Divide until the remainder is zero, or until you have enough decimal places in your answer. You can also stop if the remainder repeats because this indicates that your answer is a repeating decimal.

X
Answer:
x = 19
z = 64
Step-by-step explanation:
Angles (11x - 93)° and 116° are vertical angles, so their measures are equal.
11x - 93 = 116
11x = 209
x = 19
Angles z° and 116° are a linear pair, so they are supplementary, and their measures have a sum of 180°
z + 116 = 180

What is a histogram?The AA histogram is an approximation of the distribution of numerical data. Karl Pearson was the first to coin the phrase. The first step in creating a histogram is to "bin" (or "bucket") the range of values, which means dividing the entire range of values into a series of intervals and then counting how many values fall into each interval. Bins are typically specified as non-overlapping, consecutive intervals of a variable. The bins (intervals) must be adjacent and are frequently (but not always) of equal size.So, in the given situation the distribution consists of two clusters and a gap, which best describes the distribution.

A four-digit number is formed using four of the eight eight digits 1, 2, 3, 4, 5, 6, 7, 8. No digit can be used once. Find how many different four - digit number can be formed if
There are no restriction
Total 330 four-digit numbers can be formed if the number is odd and greater than 6000.
Let's tackle the problem in three steps.
First, take into account the numbers with "6" as the first digit on the left.
Then take the first eight digits of the numbers as the leftmost digit.
Last but not least, we'll use the numbers that begin with "7" as the leftmost digit.
1. As the leftmost digit, think of the numbers that begin with "6."
Any one of the final four odd digits—1, 3, 5, or 7—is acceptable (and recommended).
You are given four options.
You can use any of the remaining 8-1-1 = 6 digits for the second and third digit.
In all, it gives you 4×6×5 = 120 choices/numbers.
2. Consider the leftmost digit as the number starting with "6."
You have 120 more options/numbers using the same logic and analysis.
Everything is going well thus far, and you only need 120 + 120 = 240 numbers.
3. Consider the numbers starting with "7" as leftmost digit.
Any of the final three odd digits—1, 3, and 5—may (and ought to) be used.
You have three options.
Any of the remaining 8-1-1 = 6 digits can be used for the second and third digit.
In all, it gives you 3×6×5 = 90 choices/numbers.
4. You have 120 + 120 + 90 = 330 numbers/options when everything is added up.
Hence we get 330 choices to create four digit numbers.
