The original price of the used car, before the 25% reduction, was approximately $8,000. This was calculated by considering that $6,000 represents 75% of the original price.
Explanation:The question is related to percentage and price, which falls under the realm of Mathematics. To find the original price of the car, you must consider that the price after the 25% discount was $6,000. This 25% reduction means that $6,000 represents 75% of the original price because 100% - 25% equals 75%. To find the original price (which is 100%), you can set up a simple equation and solve for the original price using cross multiplication. The equation will look like this:
75/100 = 6000/x
When you cross multiply and solve for x, the result is $8,000. So, the original price of the car was approximately $8,000.

Shyam invested money in the stock market. In the first year, his stock increased 20%. He paid his stock broker $300 and then lost $450. He withdrew $500, and then his remaining investment doubled. Shyam’s investment is now worth $7100. How much was Shyam’s original investment?
Answer:
Shyam's original investment was $4000.
Step-by-step explanation:
Suppose, Shyam's original investment was [tex]x[/tex] dollar.
In the first year, his stock increased 20%. So, the value of the stock will be: [tex](x+0.20x)=1.20x[/tex] dollar.
He paid his stock broker $300 and then lost $450. So now, the value of the stock will be: [tex](1.20x-300-450)=(1.20x-750)[/tex] dollar.
He then withdrew $500, so the value of the remaining investment [tex]=(1.20x-750-500)=(1.20x-1250)[/tex] dollar and this remaining investment doubled now.
So, the value of the investment now [tex]=2(1.20x-1250)[/tex] dollar, which is given as $7100.
Thus, the equation will be.......
[tex]2(1.20x-1250)=7100\\ \\ 2.40x-2500=7100\\ \\ 2.40x=7100+2500=9600\\ \\ x=\frac{9600}{2.40}=4000[/tex]
So, Shyam's original investment was $4000.

Maria needs to make a total of 80 deliveries this week. So far she has completed 48 of them. What percentage of her total deliveries had Maria completed?
Maria has completed 60% of her total deliveries this week. This was calculated by creating a ratio of completed deliveries to total deliveries, converting this ratio to a decimal, and then converting the decimal to a percentage.
Explanation:To find what percentage of deliveries Maria has completed, we start by creating a ratio of completed deliveries (48) to total deliveries (80). This ratio is expressed as a fraction, so we write it as 48/80.
Next, we convert this fraction to a decimal by dividing the numerator (top number) by the denominator (bottom number). So, 48 ÷ 80 = 0.6
To convert the decimal to a percentage, we multiply by 100, so 0.6 x 100 = 60%.
Therefore, Maria has completed 60% of her total deliveries so far.

Choose a method then find the product 16 times 60
Using the multiplication method, we find that 16 times 60 equals 960.
To find the product of 16 times 60, we can use the method of multiplication. The multiplication method is a straightforward way to find the product of two numbers by multiplying each digit separately and adding the results.
1. Write down the two numbers being multiplied: 16 and 60.
2. Start by multiplying the rightmost digit of the bottom number (60) with the top number (16). In this case, multiply 0 with 16, which equals 0.
3. Write down the result (0) below the line.
4. Now, multiply the next digit of the bottom number (6) with the top number (16). Multiply 6 with 16, which equals 96.
5. Write down the result (96) below the line, shifted one position to the left.
6. Finally, add the two results together: 0 + 96 = 96.
So, the product of 16 times 60 is 960.

If the graph of y = |x| is translated so that too. (1, 1) is moved to (4, 1) what is the equation of the new graph
Answer: y = |x-3|
The point (1,1) has been moved 3 spots to the right to get to (4,1). The entire equation of the V shaped curve will also move 3 spots to the right. So that's how we go from |x| to |x-3|. Note how plugging in x = 4 leads to y = |x-3| = |4-3| = |1| = 1
the sum of two consecutive odd integers is 284 . write a equation and solve to find the two integers
Let the consecutive odd numbers be( x) and (x+2).
According to given condition.
(x)+(x+2) =284
solving x+x+2 =284
2x+ 2 =284
subtracting 2 both sides
2x+ 2-2 =284-2
2x =282
dividing 2 both sides
x=141
as the second integer is (x+2) so
x+2 =141+2= 143
so integers are 141 and 143.

Remember that dividing by a number is the same as multiplying by its reciprocal. To get a number's reciprocal, flip the numerator and denominator around.
In this case, 3/5's reciprocal is 5/3. With this information in mind, flip 3/5 to it's reciprocal, change the division sign to multiplication, then multiply as such:
[tex]\frac{7}{8} \times \frac{5}{3}=\frac{35}{24}[/tex]
Your final answer is 35/24.
12.Now firstly, we want to convert these mixed fractions into improper fractions. To convert them, multiply the whole number by the denominator then add the numerator and that's your new numerator. In this case:
[tex]2\frac{1}{10}=\frac{2*10+1}{10}=\frac{21}{10}\\\\1\frac{1}{5}=\frac{1*5+1}{5}=\frac{6}{5}\\\\\frac{21}{10}\div \frac{6}{5}[/tex]
Next, we want to convert this expression to multiplication. Similar to before, convert 6/5 to its reciprocal, change the multiplication sign to division, and multiply as such:
[tex]\frac{21}{10}\times \frac{5}{6}=\frac{105}{60}[/tex]
Now you may think that 105/60 is the right answer, however we can simplify it further. The numerator and the denominator have a GCF, or greatest common factor, of 15. With this, divide the fraction by 15/15 as such:
[tex]\frac{105}{60}\div \frac{15}{15}=\frac{7}{4}[/tex]
Your final answer is 7/4.

To prove that 3√5 is irrational, assume the product is rational and set it equal to a/b, where b is not equal to 0. Isolating the radical gives √5= a/3b (All one fraction). The right side of the equation is [Rational or Irational]. Because the left side of the equation is [Rational or Irational], this is a contradiction. Therefore, the assumption is wrong, and the number is [Rational or Irational].
Answer:
Rational; irrational; irrational.
Step-by-step explanation:
a/3b is a rational number, as it is represented by a fraction and b ≠ 0. This means the first blank is "rational."
√5 is an irrational number. This means the second blank is "irrational."
Since we have an irrational number set equal to a rational number, this is a contradiction. This means our original assumption is wrong, and the number is irrational. This is the third blank.
There are Rational, irrational, and irrational are the correct options respectively.
What is a rational number?A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.
It can be a/b of two integers, a numerator a, and a non-zero denominator b.
Given Number = 3√5
We have to prove that 3√5 is an irrational number.
Let us assume 3√5 is a rational number.
Because it is represented as a fraction and b ≠ 0, a/3b is a rational number. This implies that the first blank is "reasonable."
The number √5 is irrational. This indicates that the second blank is "irrational."
This is a contradiction since we have an irrational number set equal to a rational number. This signifies that our initial assumption was incorrect, and the number is irrational.
Therefore, the assumption is wrong, and the product is irrational.

Answer : C
The function [tex]f(x)= x^2[/tex] has been translated 9 units up and 4 units to the right to form the function g(x)
For 9 units up, we add 9 at the end of f(x)
f(x) + 9
so equation becomes [tex]f(x)= x^2 + 9[/tex]
For 4 units right , we subtract 4 from x in f(x)
f(x-4)
So the equation becomes [tex]f(x) = (x-4)^2 + 9[/tex]
Hence [tex]g(x) = (x-4)^2 + 9[/tex]
