Required percentage value = a
total value = b
Percentage = a/b x 100
The total cost of the pair of headphones is $23.
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% = 50/200 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
105 = 10/100 = 1/10
We have,
Original price of the headphones = $50
60% of $50
= 60/100 x 50
= $30
The price of the headphones after the discount.
= $50 - $20
= $20
The amount of sales tax.
= 15% of $20
= 15/100 x 20
= $3
The total cost.
= $20 + $3
= $23
Thus,
The total cost of the pair of headphones is $23.

In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angle.
Write and solve an equation to determine the measure of angle x.
Answer:
X =50 Y is also 50 since they are vertical angles
Step-by-step explanation:
70+ 60 + X = 180 (the 3 angles form a straigh line = 180 )
130 +X =180
X = 180-130

Angie and Kenny play online video games. Angie buys 2 software packages and 3 months of game play. Kenny buys 1 software package and 1 month of game play. Each software package costs $30. If their total cost is $170, what is the cost of one month of game play?
Answer:
$20
Step-by-step explanation:
Kenny's gameplay: 1 month
Angie's gameplay: 3 months
1+3= 4
Kenny bought 1 software pack
Angie bought 2 software packs
1+2= 3
Each software package= $30
So 30×3= 90
Total cost= $170
170-90= 80
80÷4= $20

Find the missing measure of the arc formed by the endpoints of a central angle.
Answer:
The missing measure of the arc is 125°.
Step-by-step explanation:
Since the circle is 360°, you would first subtract 360 by the degrees given: 360-115-35-85 and the sum is 125. Then, you would set 125 equal to -32x-3 to solve for x.
[tex]125=-32x-3[/tex]
[tex]+3[/tex] [tex]+3[/tex]
-----------------------
[tex]\frac{128}{-32} =\frac{-32x}{-32}[/tex]
[tex]x=-4[/tex]
The missing measure of the arc is 125°.

Answer:
The length of the side DE is approximately 541.3 feet long.
Step-by-step explanation:
There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{x} =\frac{sin(10^{o})}{94}[/tex] ⇒ [tex]\frac{x}{sin(90^{o})} =\frac{94}{sin(10^{o})}[/tex] ⇒ [tex]x = \frac{94*sin(90^{o})}{sin(10^o)}[/tex] ⇒ [tex]x=541.3ft.[/tex]

Colton sold a total of 28 tee shirts and sweatshirts as a fundraiser for his football team. If tee shirts cost 12 dollars each and sweatshirts cost 20 dollars each and he raised a total of 424 dollars how many tee shirts did he sell?
Answer:
17
Step-by-step explanation:
Create a system of equations where t is the number of t shirts he sold, and s is the number of sweatshirts he sold
t + s = 28
12t + 20s = 424
Solve by elimination by multiplying the top equation by -20, then adding them together
-20t - 20s = -560
12t + 20s = 424
-8t = -136
Solve for t:
t = 17
So, Colton sold 17 t shirts

Finding the product of 9, 10 and 9 ; 810
Step-by-step explanation:
Given that :
Length = 10 feets
Width = 9 feets
Height = 9 feets
The volume of a rectangular prism is obtained by :
Length * width * height
The volume could be obtained by taking the product of 10, 9 and 9
Hence, the volume of the rectangular prism is :
(10 * 9 * 9) feet³ = 810 feet³
Number of 1 feet³ boxes = 810 feet³ / 1 feet³ = 810

Trinity and Peyton were collecting box tops for their class. Trinity collected 36 box tops. Peyton collected
1 ½ times as many. How many cans did they collect all together?
Note: We need to find the number of total box tops instated of total number of cans.
Given:
Trinity collected 36 box tops.
Peyton collected [tex]1\dfrac{1}{2}[/tex] times as many as Trinity.
To find:
The number of box tops they did collect all together.
Solution:
It is given that,
Number of box tops collected by Trinity = 36
Number of box tops collected by Peyton = [tex]1\dfrac{1}{2}\times 36[/tex]
= [tex]\dfrac{3}{2}\times 36[/tex]
= [tex]54[/tex]
Total = [tex]36+54[/tex]
= [tex]90[/tex]
Therefore, the total number of box tops collect all together is 90.
7. The population of Flood River City is now 42,000. Experts predict the population will decrease 25% each
year for the next five years. What will be the population in five years?
Answer: The population after five years = 9967
Step-by-step explanation:
The exponential equation for population decay : [tex]P=A (1-r)^t[/tex], where A = initial population r= rate of decay , t= time
Given: A= 42000, r= 25%= 0.25, t= 5
then
[tex]P=42000(1-0.25)^5\\\\=42000(0.75)^5\\\\=42000(0.2373046875)\\\\\approx9967[/tex]
Hence, The population after five years = 9967
