The Cookie Shop's profit at the end of January will be $12000.
The profit earned by the shop at the end of December = $15000
The profit decreased by 20% at the end of January
Therefore decrease percentage, which is used to determine the percentage decrease of two values (final value and initial value)
[tex]Decrease percentage = \frac{Final value - Initial Value}{Final Value} * 100[/tex]
According to the formula, the initial value is subtracted from the final value. The resulting value is divided by the initial value and multiplied by 100 to obtain the decreased percentage
Decrease Percentage 20%
Final value = $15000
[tex]20 = \frac{15000 - Initial Value}{15000} * 100[/tex]
[tex]\frac{20}{100} = \frac{15000 - Initial Value}{15000}[/tex]
[tex]\frac{20}{100} * 15000 ={15000 - Initial Value}[/tex]
20 * 150 = 15000 - Initial Value
3000 = 15000 - Initial Value
Initial value = 15000 - 3000
Initial value = $12000
The profit earned by the Cookie Shop at the end of January will be $12000.

How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2

Please help with the question on the photo :)
Answer:
Explanation:
a) To work out the average or mean age we must first calculate the total age.
19 x 2 = 38
20 x 3 = 60
21 x 1 = 21
22 x 4 = 88
23 x 1 = 23
Total = 230
Then... Divide the number of players with this figure
Number of players = 2 + 3 + 2 + 4 + 1 = 11
230/11 = 20.9 is the average age of the players
b) We know the average will now be 22 and we know the number of players is now 12.
So... 22 x 12 = 264 (This will be the new total age of all the players)
We know the previous total was 230
So 264-230 = 34 (years old)

The sum of an integer and 6 times the next consecutive integer is -50. Find the
value of the greater integer.
Answer:
Submit Answer
Dar
The value of the greater integer is -8.
Given,
The sum of an integer and 6 times the next consecutive integer = -50
We have to find the value of the greater integer:
Let's take x as the integer.
Next consecutive integer be (x + 1)
Now,
x + 6(x + 1) = -50
x + 6x + 6 = -50
7x + 6 = -50
7x = -50 - 6
7x = -56
x = -56/7
x = -8
The value of x is -8.
Now,
x + 1 = -8 + 1 = -7
That is,
-8 + (6 × -7) = -50
-8 -42 = -50
Here, the integers are of negative values.
So, the value of greater integer be -8.

Jenny is 12 years older than Steve, Five years ago, Jenny was four times older that Steve was then. How old are Jenny and Steve now?
say Steve is x ,then jenny will be x + 12
five years ago Steve's age was x - 5 and Jenny's age was x + 12 - 5= x + 7
since jenny was four times Steve's age 5 years ago the equation will be
x + 7 = 4(x - 5)
= x + 7 = 4x - 20
putting like terms together, we will have
4x - x = 20 + 7
= 3x = 27
this means 3x ÷ 3= 27 ÷ 3
x = 9
this means Steve is 9 years old and Jenny is 21 years old

What is limit of a function how to find limit using graph?Limit : Limit is the value that a function output approaches as the input approaches to a certain value.
For any function g(x) , [tex]\lim_{x \to \22} g(x)[/tex] refers to the value that the g(x) approaches as the x approaches to 2 from either left hand side or from right hand side
From any graph we can easily see that to what value g(x)=y on the curve is approaching when the x is approaching to some value on x axis and if the graph is splitting into different functions on the value of x where x is approaching then the limit does not exist for that value of x.
For given graph h(x)
We can see value of value of function h at x=5 is 8 and value of function h at x=7 is 4
As the graph of h(x) has a hole in the graph when x=5, breaking its function into two different function on x=5 then or limit of h(x) at x=5 does not exist
As the graph of h(x) has a hole in the graph when x=7, breaking its function into two different function on x=7 then or limit of h(x) at x=7 does not exist
As the graph is not breaking at x=8or we can say that graph of g(x)is approaching to 5 as x approaches to 8 then limit of h(x) at x=8 is equal to g(1) that is 5

The general form of a linear equation is y - y1 = m(x - x1). The point-slope form is y = - 1.75x.
What is point-slope form?The general form of a linear equation is y - y1 = m(x - x1). It draws attention to the line's slope and one of the line's points (that is not the y-intercept).
Given: (x1, y1) = (0, 0) and (x2, y2) = (-4, 7)
The point-slope form is given by,
y - y1 = m(x - x1)
m = (y2 - y1)/(x2 - x1)
substitute the values in the above equation, we get
m = (7- 0)/(-4 - 0) = -7/4

Δ A B C is a right isosceles triangle with hypotenuse AB. M is the midpoint of AB. Write a coordinate proof to show that CM is perpendicular, to AB.
It is proved that CM will be perpendicular to AB if M is midpoint of AB.
It is given that ΔABC is a right isosceles triangle with hypotenuse AB and M is midpoint of AB.
We have to prove that CM is perpendicular to AB.
What is an isosceles triangle ?
An isosceles triangle ΔABC is a triangle that has at least two sides of equal length i.e., AC= BC
As per the question ;
ΔABC is a right isosceles triangle with hypotenuse AB.
⇒ AC = BC (by the definition of isosceles triangle)
Also ;
M is midpoint of AB.
⇒ CM = CM (reflexive property)
So ;
ΔACM ≅ Δ BCM (by SSS)
∠A = 45° and ∠B = 45° because of right isosceles triangle.
Also ;
∠ACM = ∠BCM
because they are corresponding angles of congruent triangles
i.e.,
∠ACB = 90°
Now ;
∠ACM + ∠BCM = ∠ACB
because they are adjacent angles.
∵
∠ACM = ∠BCM , so ;
∠ACM + ∠ACM = ∠ACB
2∠ACM = 90°
∠ACM = 45 °
∵
∠A = 45 ° and ∠ACM = 45°
⇒ ∠AMC = 90°
because the sum of angles in a triangle is 180°.
So ,
If ∠AMC = 90° , then CM is perpendicular to AB because perpendicular lines form 90° angles.
Thus , CM will be perpendicular to AB if M is midpoint of AB.

The the solution of the linear equation in one variable 7(a+1)-3 a=5+4(2a-1) is at a = 3/2.
According to the given question.
We have a linear equation in one variable.
7(a+1)-3 a=5+4(2a-1)
As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
Thereofre, the solution of the linear equation in one variable 7(a+1)-3 a=5+4(2a-1) is given by
7(a+1) -3a = 5 + 4(2a - 1)
⇒ 7a + 7 - 3a = 5 + 8a - 4 (by distributive rule)
⇒ 4a + 7 = 1 + 8a
⇒ 7 - 1 = 8a - 4a
⇒ 6 = 4a
⇒ 6/4 = a
