The value of A in the number line is the in-between of 225 and 645 so it is 435.
What is a number line?In mathematics, a number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.
In another word, a number line is basically a line in which infinite numbers have been written in ascending order or increasing order.
A horizontal number line is the most common representation and can be extended infinitely in any direction.
Given the number line,
Now if we count the interval of A between 225 and 645 it is 2(same).
So A must be between 225 and 645.
So,
225 - A = A - 645
2A = 870
A = 435
Hence "The value of A in the number line is the in-between of 225 and 645 so it is 435".

Ross has $2 and $5 notes.
There are 15 more $2-notes than $5-notes.
The total amount of $5-notes is $90 more than the total amount of $2-notes.
What is the total value of all the $5-notes that Ross has?
p.s. get the qn right i will mark u brainliest
By solving a system of equations we can conclude that ross has a total of $200 in $5-notes.
What is the total value of all the $5-notes that Ross has?
Let's define the variables:
x = number of $5-notes that Ross has.y = number of $2-notes that Ross has.We know that there are 15 more $2-notes than $5-notes, then:
y = x + 15
And the total amount of $5-notes is $90 more than the total amount of $2-notes.
x*5 = 90 + y*2
Then we have a system of equations:
y = x + 15
x*5 = 90 + y*2
Replacing the first equation into the second one we get:
x*5 = 90 + (x + 15)*2
Now we can solve this for x:
x*5 = 90 + x*2 + 30
5*x - x*2 = 90 + 30
3*x = 120
x = 120/3 = 40
x = 40
In this way, we conclude that Ross has 40 of the $5-notes, then the total value is:
40*$5 = $200

Erin charged $900 on the current credit card this billing cycle. Erin pays $300 towards the balance by the due date, but is unable to pay the remaining $600. The balance of $600 carries over to the next billing cycle, but he must pay interest on this amount as well. If the APR is 15%, how much interest will be added to the payment for the next billing cycle?
$690 is the next bill payment will be added for the next billing cycle.
What is rate of interest ?
An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.
Total payment charged = $900
amount paid = $300
amount remained = $600
APR on $600 = 15%
= 600*15/100
= 600*0.15
= $90
Therefore, in the next bill total amount charged is 600 +90 = $690

A rectangle has a length of 3x+ 1 and a width of 2x - 9 write an expression for the perimeter of the rectangle
Given the length and width, the expression for the perimeter of the rectangle is 10x - 16.
What is the expression for the perimeter of the rectangle?The perimeter of rectangle is expressed as;
P = 2( l + w )
Where l is length and w is width.
Given the data in the question;
Length l = 3x+ 1Width w = 2x - 9Plug the given values in the equation above

The function f(x) = (x − 4)(x − 2) is shown. On a coordinate plane, a parabola opens up. It goes through (2, 0), has a vertex at (3, negative 1), and goes through (4, 0). What is the range of the function? all real numbers less than or equal to 3 all real numbers less than or equal to −1 all real numbers greater than or equal to 3 all real numbers greater than or equal to −1 Mark this and return Save and Exit Next
Step-by-step explanation:
all real numbers greater than our equal to -1.
as the parabola function is y = something in x², the parabola opens up either up or down.
if the function would have been x = something in y², the parabola would open left or right.
but our parabola here opens therefore up and down.
the vertex is therefore the maximum or minimum of the parabola. y does not get larger or smaller than the y value of the vertex.
as we see that the curve goes through points with y value 0 (which is clearly larger than -1), it means the vertex is a minimum, and the parabola opens up.
therefore the answer at the beginning. any y value of the function can only be greater than or equal to -1.

A rectangular piece of metal is 5 in. longer than it is wide. Squares with sides 1 in. long are cut from the four corners, and the
flaps are folded upward to form an open box. Which equation indicates that the volume of the box is 56 in.³?
The equation which shows the volume of rectangular box is w² + 5w - 56 = 0.
What is defined as the rectangle?A rectangle is a two-dimensional (2D) shape with opposite sides that are parallel as well as equal to each other and four right angles.
The breadth (width) of a rectangle is the shorter side, and the length is the longer side.
The metal's length is 5 inches longer than its width. However, we fold up 1-inch flaps on every side, resulting in a 1-inch box height and an 2-inch decrease in length and width (1 inches on each side). Because the length and width both decrease in the same amount, the length remains 5 inches longer than that of the width.Then, the equations are as follows:
l = w + 5
The height of the box will be 1 inch which is cut and folded upward.
vol = l x w x h = 56 in³
Substitute the value of l in the equation.
56 = (w + 5)(w)(1)
56 = w² + 5w
w² + 5w - 56 = 0
Therefore, the equation which represent the volume of the rectangular box on 56 in.³ is w² + 5w - 56 = 0.

The daily cost, in dollars, to produce x Sasquatch Berry Pies is C(x) = 3x + 36, x ≥ 0 and
the price-demand function, in dollars per pie, is p(x) = 12 − 0.5x, 0 ≤ x ≤ 24. Find the price to charge per item in order to maximize profit.
The cost per item for maximum profit is $7.50 .
The maximum and minimum value of a function f(x) is calculated by finding the first and second derivative of f(x).
If f"(x)<0 then the function f(x) has a maximum value for x at f'(x)=0.If f"(x)>0 then the function f(x) has a minimum value for x at f'(x)=0.The cost to produce x pies is given by the cost function
[tex]C(x)=3x+36[/tex]
The price demand function for each pie is given by
[tex]p(x)=12-0.5x[/tex]
Revenue gained from selling x pies
[tex]R(x)=x\times p(x)\\or,R(x)=x\times(12-0.5x)\\or,R(x)=12x-0.5x^2[/tex]
Now profit function is given by
[tex]P(x)=R(x)-C(x)\\or,P(x)=-0.5x^2+12x-3x-36\\or,P(x)=-0.5x^2+9x-36[/tex]
Now we have to find the maximum profit. We know that for a function
[tex]P(x)=-0.5x^2+9x-36\\P'(x)=-x+9[/tex]
[tex]P''(x)=-1[/tex]
At P'(x)=0
or,-x+9=0
or, x=9
As P''(x)<0 therefore the profit function P(x) is maximum for x at P'(x)=0.
The profit is maximum at x=9
Price to charge per item=12-0.5x
Substituting the value of x we get:
[tex]p(x)=12-(0.5\times 9)\\or,p(x)=12-4.5\\or,p(x)=7.5[/tex]
Therefore the cost per item for maximum profit is $7.50 .

A game show airs on television five days per week. Each day, a prize is randomly placed behind one of two doors. The contestant wins the prize by selecting the correct door.
The probability that exactly 2(two) out of the 5(five) contestants win a prize is 31.25%.
What is probability?
Probability is the(one) branch of mathematics concerning numerical descriptions of how probable a (one) event is to do, or how likely it's that a(one) proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.The more advanced the probability of an event, the more likely it's that the event will do. A simple illustration is the tossing of a fair( unprejudiced) coin. Since the coin is fair, the two issues(" heads" and" tails") are both inversely probable; the probability of" heads" equals the probability of" tails"; and since no other issues are possible, the probability of either" heads" or" tails" is 1/2( which could also be written as 0.5 or 50).The probability that exactly 2(two) out of the 5(five) contestants win a price is given by,
P(x = 2)(two) = 5/16
