It takes 6 days for both of them to have same number of followers
Solution:
Let "x" be the number of days
Case 1:Celebrity A has 400 followers on social media and is gaining 75 followers each day
We can frame a equation as:
Celebrity A : 400 + 75(number of days)
Celebrity A : 400 + 75x --------- eqn 1
Case 2:Celebrity B has 1,000 followers on social media, but is losing 25 followers a day
We can frame a equation as:
Celebrity B : 1000 - 25(number of days)
Here we use negative sign to denote losing of followers
Celebrity B : 1000 - 25x --------- eqn 2
For both of them to have same number of followers, eqn 1 must be equal to eqn 2
[tex]400 + 75x = 1000 - 25x\\\\\text{Solve the above equation for x}\\\\75x + 25x = 1000 - 400\\\\\text{Combine the like terms }\\\\100x = 600\\\\x = 6[/tex]
Thus it takes 6 days for both of them to have same number of followers

What is the equation of a line that is parallel to the line with the equation y=2/3x+2 and passes threw the point 1,-1
The equation of line parallel to given line is: [tex]y = \frac{2}{3}x-\frac{5}{3}[/tex]
Step-by-step explanation:
Given equation of line is:
[tex]y = \frac{2}{3}x+2[/tex]
As the line is in slope-intercept form, the co-efficient of x is the slope of the line
So,
[tex]m_1 =\frac{2}{3}[/tex]
Let m2 be the slope of required line
As both the lines are parallel,
[tex]m_1 = m_2[/tex]
So,
[tex]m_2 = \frac{2}{3}[/tex]
The slope intercept form of line is:
[tex]y = mx+b[/tex]
Putting the value of the slope
[tex]y = \frac{2}{3}x+b[/tex]
To find the value of b, putting (1,-1) in the equation
[tex]-1 = \frac{2}{3}(1) +b\\-1 = \frac{2}{3} +b\\b = -1-\frac{2}{3}\\b = \frac{-3-2}{3}\\b = \frac{-5}{3}[/tex]
Putting b=-5/3 in the equation
[tex]y = \frac{2}{3}x-\frac{5}{3}[/tex]
Hence,
The equation of line parallel to given line is: [tex]y = \frac{2}{3}x-\frac{5}{3}[/tex]

A total of 631 tickets were sold for the school play. They were either adult tickets or student tickets. There were 69 fewer students tickets sold then adult tickets. How many adult tickets were sold?
Final answer:
To solve the problem, two equations were set up and solved for the number of adult tickets (A). The equations A + S = 631 and S = A - 69 led to finding that 350 adult tickets were sold for the school play.
Explanation:
The school play ticket problem is a basic algebraic question involving setting up and solving equations. We need to determine the number of adult tickets and student tickets sold, given the total tickets and the difference between them.
Let's denote the number of adult tickets as A and the number of student tickets as S. According to the information provided:
A + S = 631 (The total number of tickets sold)
S = A - 69 (There were 69 fewer student tickets sold than adult tickets)
By substituting the second equation into the first, we get:
A + (A - 69) = 631
2A - 69 = 631
2A = 631 + 69
2A = 700
A = 350
So, 350 adult tickets were sold.

Here n = 5, thus
sum = 180° × 3 = 540°
Sum the interior angles and equate to 540 for x
131 + 108 + 107 + 110 + x = 540, that is
456 + x = 540 ( subtract 456 from both sides )
x = 84

A sprinkler can spray 7 feet out and rotates in a circle to cover all directions. What is the total area covered by the sprinkler?
The sprinkler covers an area that is shaped like a circle, with its range as the radius. Using the formula for the area of a circle, πr², and substituting 7 feet for the radius, we find that the sprinkler covers approximately 154 square feet.
Explanation:The total area that the sprinkler covers can be found by considering the sprinkler's range as the radius of a circle. The formula to find the area of a circle is πr² where π (Pi) is a constant approximately equal to 3.14, and r is the radius of the circle. In this case, the radius of the area the sprinkler covers is 7 feet. So, we plug this value into the formula:
Area = π(7ft)²
Thus, the total area the sprinkler covers is approximately 154 square feet.

if steve throws a football 60meters in 3seconds what is the football speed ?
The football thrown by Steve has a speed of 20 meters per second, as it covers a distance of 60 meters in 3 seconds.
Explanation:To calculate the speed of the football that Steve throws, we can use the basic physics concept of speed which is the distance traveled divided by the time taken. Since Steve throws the football a distance of 60 meters in 3 seconds, the calculation for the speed v is:
v = distance / time = 60 meters / 3 seconds = 20 meters per second.
Therefore, the football is traveling at a speed of 20 meters per second.
Final answer:
The speed of the football thrown by Steve is 20 meters per second, calculated by dividing the distance thrown, 60 meters, by the time taken, 3 seconds.
Explanation:
If Steve throws a football 60 meters in 3 seconds, we can calculate the speed of the football by using the formula for speed: speed = distance/time. To find the speed of the football, we simply divide the distance Steve's throw covered by the time it took for the football to cover that distance.
The calculation is as follows:
Speed = Distance / Time
Speed = 60 meters / 3 seconds
Speed = 20 meters/second
Therefore, the speed of the football is 20 meters/second

(03.04 LC) Write the equation of the graph shown below in factored form.
the graph starts at the bottom left and continues up through the x axis at negative four to a maximum around y equals three and goes back down through the x axis at negative three to a minimum around y equals negative eleven and back up through the x axis at negative one
A. f(x) = (x + 4)(x − 3)(x − 4)
B. f(x) = (x − 1)(x + 3)(x + 4)
C. f(x) = (x + 1)(x + 3)(x + 4)
D. f(x) = (x − 1)(x − 3)(x − 4)
Answer:
The equation of the graph in factored is [tex]C) f(x)=(x+1)(x+3)(x+4)[/tex]Step-by-step explanation:
From the graph given,
In order to find the equation, we need to consider the points where the curve cuts x- axis
From the graph, we have
[tex]x=-4, x= -3 \, and \, x= -1[/tex]
In factor form
[tex]x+4=0, \, x+3=0, \, and \, x+1=0[/tex]
Now, combine the factors above by multiplying together to form the equation, we have
[tex]f(x)=(x+1)(x+3)(x+4)[/tex]
Therefore, the equation of the graph in factored form is [tex]f(x)=(x+1)(x+3)(x+4)[/tex]
The question requires the equation of a graph in factored form, with the graph cutting the x-axis at -4, -3 and -1. These roots correspond to the factored form of the equation as f(x) = (x + 4)(x + 3)(x + 1). However, this equation is not listed among the choices provided. The correct option is C.
The question is asking for the equation of a graph in factored form. The graph cuts the x-axis at -4, -3, and -1.
This implies these are the roots of the equation. When a graph crosses the x-axis at a particular point, it implies the x-value of that point is a root (or zero) of the polynomial.
Therefore, the roots of the function are -4, -3, and -1. We can then convert these roots into factors by changing their signs and setting them as (x - root).
Therefore, the factored form of the equation would then be: f(x) = (x + 4)(x + 3)(x + 1). However, this equation is not listed among the choices. There might be a mistake the options provided.
It's always vital to carefully check the roots and ensure they correspond to the x values where the graph intersects the x-axis.

Nike is having a sale $100 shoes is 30% off an additional 20% off what is the amount?
Answer:
50% off would be $50
Step-by-step explanation:
20% + 30% = 50% original price was $100 but now with 50% off it is $50
Nike is having a sale $100 shoes is 30% off an additional discount 20% off. The amount to be paid for shoes now is $56.
Discount is the amount of off offered by the seller to the customer on a certain product. It is always offered as a percentage of the marked price of the product to lure the customer to buy the product.
Selling price is the price at which the product is finally sold. It is the marked price of the product minus the discount given.
Marked price = $100
initial discount = 30%
price of shoes becomes = $100 - 30% of $100 = [tex]100 - \frac{30}{100} *100 = 100- 30 = 70[/tex]

You entered Kente invested a total of $8000. He invested part of the money for 2yr in a stock fund that earned the equivalent of 6.5% simple interest. He put the remaining money in an 18 month certificate of deposit that earned 2.5% simple interest. If the total interest from both investments was $855 , determine the amount invested in each account?
Step-by-step explanation:
Given,
Kente invested part of money for 2 yr in stock fund that earned the equivalent of 6.5 % simple interest.He put remaining money in a 18 month certificate of deposit that earn of 6.5%simple interest.
Let he invested in stock fund be$ x. Remaining money =$(8000-x)
∴He got interest from stock fund was = [tex]\frac{PRt}{100}[/tex]
=$[tex]\frac{x\times6.5\times2}{100}[/tex] [here P =x , R = 6.5% and t = 2 yr]
=$ [tex]\frac{{13 x}}{{100} }[/tex]
Again he got interest from deposit was = [tex]\frac{PRt}{100}[/tex]
=$ [tex]\frac{(8000-x)\times 2.5\times\frac{18}{12} }{100}[/tex] [here P = (8000-x), R=2.5% and t =[tex]\frac{18}{12} yr[/tex]]
=$ [tex]\frac{(8000-x) \times 7.5}{200}[/tex]
According to problem
[tex]\frac{{13 x}}{{100} }+\frac{(8000-x) \times 7.5}{200}= 855[/tex]
⇔[tex]\frac{26x + 60000 - 7.5}{200} =855[/tex]
⇔18.5 x =171000 - 60000
⇔x = [tex]\frac{11100}{18.5}[/tex]
⇔x = 6000
So he invested in stock fund was = $6000
and in certificate of deposit was =$(8000- 6000)= $ 2000

Crayons come in a carton a carton holds 6 packages each package holds 10 small boxes each small box holds 12 crayons how many crayons come in a carton
Answer:720
Step-by-step explanation: think about it, 6 packages, 10 per box hold 12 crayons, 10•12=120. 120•6 boxes equals 720. I may be wrong idk but try that. Im fully confident in that answer
Final answer:
To calculate the total number of crayons in a carton, multiply the number of crayons in a small box by the number of boxes in a package, and then by the number of packages in a carton. This results in 720 crayons per carton.
Explanation:
To find out how many crayons come in a carton, we need to do a series of multiplications. We start at the smallest unit, which is the crayon, and work our way up to the carton.
Each small box holds 12 crayons.Each package holds 10 small boxes, so 10 boxes × 12 crayons each = 120 crayons per package.A carton holds 6 packages, so 6 packages × 120 crayons each = 720 crayons in a carton.Therefore, there are 720 crayons in a carton.

Person A can paint the neighbor's house 6 times as fast as Person B. The year A and B worked together it
took them 2 days. How long would it take each to paint the house?
Person A takes 2.3 days to paint the house working alone
Person B takes 13.8 days to paint the house working alone
Solution:
Let "x" be the number of days it takes person A to paint the house
Person A can paint the neighbor's house 6 times as fast as Person B
Therefore.
Number of days it takes person B to paint the house = 6x
Their rates of painting are added to get the rate working together
[tex]\frac{\text{1 house}}{\text{x days}} + \frac{\text{1 house}}{\text{6x days}} = \frac{\text{1 house}}{\text{2 days}}[/tex]
[tex]\frac{1}{x} + \frac{1}{6x} = \frac{1}{2}\\\\\frac{1 \times 6}{6x} + \frac{1}{6x} = \frac{1}{2}\\\\\frac{7}{6x} = \frac{1}{2}\\\\\ x = \frac{7}{3}= 2.3[/tex]
Thus person A takes 2.3 days to paint the house working alone
Person B = 2x = 6(2.3) = 13.8
Thus person B takes 13.8 days to paint the house working alone
