Owen went shopping for a new pair of sneakers because of a sale. The price on the tag was $32, but Owen paid $16 before tax. Find the percent discount.
Answers
Answer:
50% discount
Step-by-step explanation:
Given the following question:
50% of 32
To find the answer we will use the formula to calculate percentages, and then solve by subtracting the answer from the initial cost of the sneakers.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{50\times32}{100}[/tex]
[tex]50\times32=1600[/tex]
[tex]1600\div100=16[/tex]
[tex]=16[/tex]
Or...
[tex]32\div2=16[/tex]
[tex]=16[/tex]
50% of 32 is 16 which means the shoes has a "50% discount."

Which statement is correct for the graph of the specified function?
A) The rate of change for the linear function is 2.
B) The rate of change for the linear function is −1.
C) The maximum value of the quadratic function occurs at y = 4.
D) The minimum value of the quadratic function occurs at x = 4.
Answers
The correct statement regarding the function plotted in the graph is:
C) The maximum value of the quadratic function occurs at y = 4.
What is the rate of change of the linear function?When x = 0, y = -7, and when x = -5, y = 8, hence the rate of change(change in y divided by change in x) is given by:
R = [8 - (-7)]/-5 - 0 = 15/-5 = -3
What is the maximum value of the quadratic function?It is concave down, hence it has only a maximum value at y = 4 and not a minimum value, hence option C is correct.

Answer:
[tex]\boxed{\sf{(x-4)(x-6)}}[/tex]
Step-by-step explanation:
In order to solve this problem, all you have to do is multiply their expressions by their factors.
To begin, you must group these expressions.
[tex]\sf{x^2-10x+24=\left(x^2-4x\right)+\left(-6x+24\right)}[/tex]
After that, you factor.
Solve.
[tex]\sf{x^2-4=x(x-4)}[/tex]
-6x+24=-6(x-4)
Then rewrite the problem down.
x(x-4)-6(x-4)
Factor by the common term.
(x-4)(x-6)
Therefore, the final answer is (x-4)(x-6).

Answer:
[tex]x = -9[/tex]
Step-by-step explanation:
Given equation:
[tex]25^{2x+3} = 125^{2x+8}[/tex]
Convert 25 and 125 to base 5:
[tex]\implies (5^2)^{2x+3} = (5^3)^{2x+8}[/tex]
Apply exponent rule [tex](a^b)^c=a^{bc}[/tex]
[tex]\implies 5^{2(2x+3)} = 5^{3(2x+8)}[/tex]
If [tex]a^{f(x)}=a^{g(x)}[/tex] then [tex]f(x)=g(x)[/tex]:
[tex]\implies 2(2x+3) = 3(2x+8)[/tex]
Expand:
[tex]\implies 4x+6 = 6x+24[/tex]
Subtract 6x from both sides:
[tex]\implies -2x+6 = 24[/tex]
Subtract 6 from both sides:
[tex]\implies -2x=18[/tex]

7. At what rate was an investment made that obtains $359.80 in interest compounded annually on $668 over five years?
[compound interest rate]
Answers
Answer:
Rate = 13.173% per year
Step-by-step explanation:
**Not 100% sure about this answer, but I think it's right.**
Calculation Steps:
Solving for rate r as a decimal
r = n[(A/P)^1/^nt - 1]
r = 1 × [(668.00/359.80)^1/^(1)^(5) - 1]
r = 0.131731
Then convert r to R as a percentage
R = r * 100
R = 0.131731 * 100
R = 13.173%/year

Answers
Raju’s age = 2x
To get Kai’s age, We have to subtract 6 from 2x as Kai is 6 years younger than Raju
Kai’s age = 2x -6
Sum of their ages = 29
x + 2x + 2x- 6 = 29
5x - 6 = 29
Add 6 to both sides
5x = 29 + 6
5x = 35
Dived both sides by 5
x = 35/5
x = 7
Paul’s age = 7 years
Raju’s age = 2*7
= 14 years
Kai’s age = 14 - 6

What is a circle?It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
An equilateral triangle with side lengths equal to 12√3 units is inscribed in a circle.
And half a side length of the equilateral triangle is 6√3 units.
The apothem (x) is units long and the radius of the circle will be
x² = (9√3)² - (6√3)²
x² = 243 - 108
x² = 135
x = 11.62
And the radius of the circle will be
[tex]\begin{aligned} \cos 30 &= \dfrac{6\sqrt3}{r}\\\\\dfrac{\sqrt3}{2}&= \dfrac{6\sqrt3}{r}\\\\r &= 12 \end{aligned}[/tex]
Each segment of the circle has an area that will be
Area = the difference between the areas of the sector and triangle
Area = the areas of the sector - the areas of the triangle
The area of the sector will be
[tex]\rm Sector's \ area= \dfrac{120}{360} \pi *12^2 \\\\Sector's \ area= 48\pi[/tex]
The area of the triangle will be
[tex]\rm Triangle's \ area = \dfrac{1}{2*3} * 11.62 * 12\sqrt3\\\\Triangle's \ area = 23.25\sqrt3[/tex]
Then the area of each segment will be

Hei has $1,400 in a retirement account earning 4% interest compounded annually. Each year after the first, she makes additional deposits of $1,400. After 5 years, what was her account balance if she did not make any withdrawals? Round each year's interest to the nearest cent if necessary. HELP ASAP
Answers
Answer:
$7886.16
Step-by-step explanation:
If the balance increases by 4%, it will be 104% of the original amount. 104% as a decimal is 1.04. Therefore, to calculate the balance with annual compound interest applied, multiply the balance of the account by 1.04 each year.
As Hei makes additional deposits of $1,400 for each year after the 1st year, add $1,400 to the account balance from year 2 onwards before adding the interest.
Let A = account balance
After 1 year
A = 1400 × 1.04 = $1456
After 2 years
A = (1456 + 1400) × 1.04 = $2970.24
After 3 years
A = (2970.24 + 1400) × 1.04 = $4545.05
After 4 years
A = (4545.05 + 1400) × 1.04 = $6182.85
After 5 years
A = (6182.85 + 1400) × 1.04 = $7886.16
Therefore, after 5 years her account balance will be $7886.16

Answers
Answer:
1.5 hours; 75 miles50 miles50 miles per hour; 50 miles per hourless/decreased/reduced/smallerStep-by-step explanation:
The labels on the axes of the graph tell you the meaning of the coordinates of a point on the graph. The ordered pair lists the horizontal coordinate first. The horizontal axis is labeled hours, and the vertical axis is labeled miles.
The point (hours, miles) = (1.5, 75) means Kurt drove 75 miles in 1.5 hours.
__
You can find the miles driven in 1 hour by reading the graph at the horizontal coordinate 1 hour. You find that is 50 miles. The 1 represents 1 unit, so the "unit rate" is 50 miles in 1 hour. Such a rate is also called a "speed" of 50 miles per hour.
If Kurt had driven fewer miles in an hour, the points on the graph would all have smaller vertical coordinates. The unit rate (slope) would be less than 50 miles per hour.
How many pairs of corresponging angles are formed when a transeversal is cut by 2 parallel lines?
Answers
Answer: 4
Step-by-step explanation:
There are 4 pairs of corresponding angles are formed when a transversal is cut by 2 parallel lines,
What are parallel lines?Parallel lines are the lines that do not intersect or meet each other at any point in a plane.
They are always parallel and are at equidistant from each other. Parallel lines are non-intersecting lines.
If two parallel lines are intersected by a transversal, then corresponding angles are congruent.
The angles are called corresponding angles. If two parallel lines are cut by a transversal, the corresponding angles are congruent.
When a line is cut by a transversal, 4 angles are formed,
2 angles are >=90° while 2 are <=90°
So when we take 2 parallel lines, 4 pairs are formed.
Hence, there are 4 pairs of corresponding angles are formed when a transversal is cut by 2 parallel lines,
