At a sale, coats were sold for 52% of their original price. If the coats originally cost
$200 each, how much did a coat cost on sale?
Help me please
Answer:
Answer is 104
Step-by-step explanation:
The selling price of the coat is $104.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Original price = $200
Selling price.
= 52% of $200
= 52/100 x 200
= $104
Thus,
$104 is the selling price of the coat.

The value of x in fraction is 40/9.
What is fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
x/5 = 8/9
Now, solving for x we get
x= 8/9 (5)
x = 40/ 9.
Hence, the value of x is 40/9.

Factor f(x) into linear factors given that k is a zero of f(x).
f(x) = 4x3 + 23x² – 34x +7; k= 1
f(x) = (Factor completely.)
Step-by-step explanation:
step 1. if k is a zero then (x - 1) is a factor of 4x^3 + 23x^2 - 34x + 7.
step 2. we "can" use long division but synthetic division is easier!
step 3. 1 4 23 -34 7
4. 4. 27. -7.
4 27. -7. 0 (must get 0)
step 4. so the factors are (x - 1)(4x^2 + 27x - 7).
step 5. please note if you multiply these factors together you will get the original polynomial!

The maximum value that the function reaches is 0, which occurs at x = 6.
What is a Quadratic equation?ax²+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
Since a blank grid is given, we can plot the graph of the quadratic function f(x) = x^2 - 5x - 24 using the given points:
X: 10 -8 6 4 2 4 6 8 10
f(x): -116 -12 0 -8 -20 -8 0 8 24
The graph of the quadratic function looks like a parabola opening upwards, with the vertex at the point (2, -20).
Based on the graph, we can make the following observations:
The function has a minimum value of -20, which occurs at x = 2.The function is symmetric about the vertical line that passes through the vertex (2, -20).The function intersects the x-axis at x = -3 and x = 8.The function intersects the y-axis at y = -24.Therefore, the statement that is NOT a true description of this quadratic function is:
"The function has a maximum value of 24, which occurs at x = 10."
This statement is not true because the function has a minimum value of -20 at x = 2, but it never reaches a maximum value of 24. The maximum value that the function reaches is 0, which occurs at x = 6.
