The selling price of this hair clip will be $ 1.50.
Cost price of the clip is = $ 0.50
Markup price = 200 percent
Mark up price = 200 % of 0.5
Mark up price = 200 / 100 × 0.50
Mark up price = 2 × 0.50
Mark up price = $ 1
Selling price of the product will be:
SP = $ 0.50 + $ 1
SP = $ 1.50
Therefore, we get that, the selling price of this hair clip will be $ 1.50.

The graph shows the equation x=y^2 use the slider for a to move the vertical line on the graph. According to the vertical line test, is this equation a function why or why not?
Explanation
We are given the equation:
[tex]x=y^2[/tex]We are to use the vertical line test to determine if the equation is a function or not
The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function by visually examining the number of intersections of the curve with vertical lines.
The typical example below helps give a better explanation
So for the function
[tex]x=y^2[/tex]We can observe that the equation is not a function because the vertical line cuts the graph in more than one point
This is shown below for values of x = and x =8
Thomas runs 34 of a mileevery day for 5 days. Howfar has he run total?
Guven:
Miles per day = 34 miles
Number of days = 5 days
To find the total distance(miles), we have:
Total distance = distance covered per day x Number per days
= 34 x 5 = 170 miles
Therefore, the total distance he has covered is 170 miles
ANSWER:
170 miles

Each month Mark‘s phone company charges a flat fee of $12 plus $0.05 per minute his bill for last month was $18 how many minutes did Marty talk on the phone last Month
Given:
Flat fee = $12
Per minute charge = $0.05
Total bill for last month = $18
To find the number of minutes, we have the equation:
18 = 12 + 0.05M
Where M represents number of minutes
Let's solve for M:
Subtract 12 from both sides:
18 - 12 = 12 - 12 + 0.05M
6 = 0.05M
Divide both sides by 0.05:
[tex]\begin{gathered} \frac{6}{0.05}=\frac{0.05M}{0.05} \\ \\ 120\text{ = M} \end{gathered}[/tex]Therefore, Marty spent 120 minutes talking on the phone last month.

Step-by-step explanation:
accounts that earn 6% interest. If Emma’saccount earns simple interest and Paul’saccount earns compound interest, which is thevalue of each person’s account after 8 years?A. Emma – $2,960; Paul – $3,187.708. Emma – $960; Paul – $3,187.70C. Emma – $2,960; Paut- $ 1,187.70
So,
Remember that the simple interest of an initial amount after "t" years, can be found using the following formula:
[tex]A=P(1+rt)[/tex]Where A is the final amount, P is the initial amount, r is the rate and t are the years involved.
If we replace our values, Emma will has the following amount after 8 years:
[tex]\begin{gathered} A=2000(1+\frac{6}{100}(8)) \\ A=2960 \end{gathered}[/tex]So, Emma will has $2,960 after 8 years.
To find the amount that Paul will has, we should remember what the compound interest is.
Remember that the compound interest is given by the formula:
[tex]A=P(1+i)^n[/tex]Where A is the final amount, P is the initial amount, i is the rate and n are the years involved.
If we replace our values, Paul will has the following amount of money after 8 years:
[tex]\begin{gathered} A=2000(1+\frac{6}{100})^8 \\ A=3187.70 \end{gathered}[/tex]So, Paul will has $3187,70 after 8 years.
Therefore, the correct answer is A.
Rita is applying for a job as an engineer. Her starting salary at Company A will be $80,000 with an $800 yearly raise. Her starting salary at company B will be $65,000 with a 5% increase each year. If Rita is working at a company for 5 years. Which company should she pick?
Given:
In company A, starting salary is $80,000.
The yearly increment is $800.
So,
80,000+800=80,800
80,800+800=81,600
81,600+800=82,400
82,400+800=83,200
83,200+800=84,000
So, at the 5 year, she will get $84,000
In company B,
The initial salary is $65000 with a 5% increase each year.
So,
[tex]\begin{gathered} 65000\times\frac{105}{100}=68250 \\ 68250\times\frac{105}{100}=71662.5 \\ 71662.5\times\frac{105}{100}=75245.625 \\ 75245.625\times\frac{105}{100}=79007.906 \\ 79007.906\times\times\frac{105}{100}=82958.30 \end{gathered}[/tex]In the 5th year, she will get $82,958.30.
If Rita is working at a company only for 5 years, then she would choose company A. Because she will get salary in company A more than company B.
But, if she works for more than 5 years, she will get a salary in company B more than company A.
I need help to find the indicated operation:g(n)= 2n-2h(n)= n^2+3nFind (g×h)(n)
Composition of functions:
You combine two functions bycomposition by using one of the functions to substitute the independient variable in the other one.
To find (g o h)(n) you substitute the n in the function g(n) for the function h(n):
[tex](g\circ h)(n)=2(n^2+3n)-2[/tex]Simplify:
[tex](g\circ h)(n)=2n^2+6n-2[/tex]9. A coin is tossed and a number cube is rolled. What is the probability of getting tails and rolling a two?
Okay, here we have this:
Considering the provided information, we are going to calculate the requested probability, so we obtain the following:
Probability of getting tails and rolling a two=Probability of getting tails * Probability of getting a two
And basing ourselves on the fact that when tossing a coin there are two possible events and in this case a favorable one, and when tossing the die there are 6 possible events and one favorable for this case, we have:
Probability of getting tails and rolling a two=1/2*1/6
Probability of getting tails and rolling a two=1/12
Finally we obtain that the probability of getting tails and rolling a two is 1/12.
(4t^2-5u)^2What does this simplify to?What is the degree of the simplified answer?
Answer:
simplified expression = 16t⁴ - 40t²u + 25u²
degree = 4
Explanation:
The initial expression is:
[tex](4t^2-5u)^2[/tex]To simplify, we can solve the expression as:
[tex](4t^2-5u)(4t^2-5u)[/tex]Applying the distributive property, we get:
[tex]\begin{gathered} 4t^2(4t^2)+4t^2(-5u)-5u(4t^2)-5u(-5u) \\ 16t^4-20t^2u-20t^2u+25u^2 \end{gathered}[/tex]Adding the like terms, we get that the simplified expression is
[tex]16t^4-40t^2u+25u^2[/tex]Then, the degree of the simplified expression is 4 because it is the maximum exponent.
So, the answers are:
16t⁴ - 40t²u + 25u²
degree = 4

If the distance from South Bend to Grand Rapids has been rounded to the nearestten and is listed as 120 miles, the actual distance is between what two mile numbers?
We need to have two numbers between 116 and 124. If we have these two numbers and average them, we can have:
[tex]\frac{116+124}{2}=120[/tex]If we rounded 116 to the nearest ten, it will be 120.
If we rounded 124 to the nearest ten, it will be also 120.
Then if we have these two numbers and average them, we finally have 120 miles.
The actual distance must be between 116 and 124.

The mean (or average) of observations is the sum of the values of all the observations divided by the total number of observations.
The mean for grouped data is given by:
[tex]Mean=∑(f_i.x_i)/∑f_i[/tex]• So; first we calculate each class mark xi, as:
(0 + 3)/2 = 1.5
(4 + 7)/2 = 5.5
(8 + 11)/2 = 9.5
• Now; we calculate fixi, as:
1.5 x 12 = 18
5.5 x 20 = 110
9.5 x 8 = 76
• Hence, the mean is given by:
[tex]Mean=\frac{18+110+76}{12+20+8}=5.10[/tex]ANSWER

The algebraic expression is -20 +4.
What is algebraic expression?
An algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x2 − 2xy + c is an algebraic expression.
Given, situation -20 increased by 4.
Translate the phrase -20 increased by 4 into an algebraic expression.
You probably already know that more than is associated with addition so the sign is not going to change. But what about the order of the terms?
Think about it this way: we have a number (some unknown value) and this phrase represents -20 increased by whatever that value is. So, in this case, you will start with the number -20 and add 4.
we get -20+4.

To find the mass in grams of the volume of acetone, multiply the volume by the density (always check the units, that in this case are consistent because 1cm^3=1mL):
[tex]17.56mL\cdot\frac{0.7857g}{mL}=13.79g[/tex]To find the volume of the mass of acetone, divide the mass by the density:
