A clothing business finds there is a linear relationship between the number of shirts, n , it can sell and the price, p , it can charge per shirt. In particular, historical data shows that 1,000 shirts can be sold at a price of $30 , while 3,000 shirts can be sold at a price of $20 . Find a linear equation in the form p(n)=mn+b that gives the price p they can charge for n shirts.
The linear Equation in the form of p(n)=mn+b is p(n) = -0.005n + 999.85.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
In particular, historical data shows that 1,000 shirts can be sold at a price of $30 , while 3,000 shirts can be sold at a price of $20 .
p = price
n = number of shirts
m = slope of the line (note, the more shirts, the lower the price, so we know it's going to be negative)
b = y intercept
so, the slope is
= (20- 30)/ (3000 - 1000)
= -10 / 2000
= -0.005
and, the equation is
p - 1000 = -0.005 ( n- 30)
p- 1000 = -0.005n + 0.15
p(n) = -0.005n + 999.85

The value of m∠C in the triangle is 42.77°
How to find the value of m∠C?
The sine rule is a mathematical formula used in trigonometry to find the length of a side or the size of an angle in a triangle when two sides and one of the angles opposite to those sides are known. It states that:
a/sin A = b/sin B = c/sin C
Where a, b, and c are the lengths of the sides of the triangle and A, B, and C are the angles opposite to those sides.
m∠A = 47°, a = 28, c = 26.
a/sin A = c/sin C
28/sin 47° = 26/sin C
sin C = (26 sin 47°)/28
sin C = 0.6791
C = arcsin(0.6791)
C = 42.77°
Thus, m∠C = 42.77°

Alexa opens a retirement account and is starting with $100. He plan to add $25 each month to the account ? What’s is the equation and how much money will Alexa have after 6 months and after 12 months ?
Answer:
The equation to calculate the balance in the account after "x" months would be: y = 100 + 25x
And after 6 months, Alexa would have $250 in his retirement account, and after 12 months, he would have $400 in his account.
Step-by-step explanation:
Let's call the balance in Alexa's retirement account after "x" months "y".
The equation to calculate the balance in the account after "x" months would be:
y = 100 + 25x
After 6 months, Alexa would have added 6 * $25 = $150 to the original balance of $100, so the balance would be:
y = 100 + 25 * 6 = 100 + 150 = $250
After 12 months, Alexa would have added 12 * $25 = $300 to the original balance of $100, so the balance would be:
y = 100 + 25 * 12 = 100 + 300 = $400
So, after 6 months, Alexa would have $250 in his retirement account, and after 12 months, he would have $400 in his account.

Samuel is trying to decide between two laser printers, one manufactured by
Hewlett-Packard, the other by Brother. Both have similar features and warranties, so price is the determining factor. The Hewlett-Packard costs $200, and printing costs are approximately $0.03 per page. The Brother costs $240, and printing costs are approximately $0.01 per page. How many
pages need to be printed for the cost of the two printers to be the same? Show work.
Answer: Let's call the number of pages printed "x". After printing x pages, the total cost for the Hewlett-Packard printer will be:
$200 + $0.03 * x
And the total cost for the Brother printer will be:
$240 + $0.01 * x
We want to find the number of pages "x" such that the cost of the two printers is the same, i.e., when:
$200 + $0.03 * x = $240 + $0.01 * x
We can isolate x by subtracting $240 from both sides and subtracting $0.01 * x from both sides:
$200 - $240 + $0.03 * x - $0.01 * x = 0
$-40 + $0.02 * x = 0
$0.02 * x = 40
x = 2000

What is the area, in square units, of the shaded
portion?
The area of the shaded portion of the given figure is 84 sq. units.
What is meant by area?
The size of a region on a surface is determined by its area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a structure or planar lamina.
From the figure, we can conclude that,
Area of the shaded portion = Area of the square - Area of the four congruent parallelograms.
Now we have to find the area of square and parallelograms separately.
Area of square
Side length l = 12
Area = l *l = 12 * 12 = 144 sq. units
Area of parallelograms
Base b = 5
Height h = 3
Area of 1 parallelogram = b.h = 5 * 3 = 15 sq. units
Since all the parallelograms are congruent,
Area of all 4 parallelograms = 15 * 4 = 60 sq. units
Hence the area of the shaded portion of the given figure = 144 - 60
= 84 sq. units

Samantha mixes some amount of 25% sugar syrup with x grams of 10% sugar syrup. The result is 120 grams of 15% sugar syrup. How many grams of 25% sugar syrup did Samantha use?
Answer:
120-x
Step-by-step explanation:
For me in class there were 6 parts to this problem and this problem is the same in my class so I will add all the answers
So for how many grams of 25% syrup it will be 120-x because the some amount + x = 120 grams of 15% syrup
so 120-x = the some amount of syrup.
This will be the answer for the problem you were asking for
If you have 6 parts keep scrolling since I will supply some more answers
Next part: How much pure sugar is in the 25% syrup?
For the amount of pure sugar there is in the 25% syrup
that will equal 0.25(120-x) = 30-0.25x
Next: How much sugar is in 120 grams of 15% sugar syrup?
10% of 120 is 12
5% = 12/2 = 6
12+6 = 18
Now the earlier stuff from the problem will come in handy
use the previous answers to write an equation
0.25(120-x)+0.10x=18
= 30-0.25x+0.10x=18
30 -0.15x=18
Now the final part to solve the equation and find the 10% solution and the 25% solution
-0.15x=18-30 = -12
-0.15x=-12
x= -12/-0.15
x=80
the problems not done yet though
we need to find the 25% solution
25% solution = 120-x and x = 80
120-80 = 40
The 10% solution is 80 grams and the 25% solution is 40 grams
If y is proportional to the square root of x and y is=21 when x=49 find y when x =144
Answer:
y = 36
Step-by-step explanation:
Because the problem says y is proportional to the square root of x, we can assume that it is directly proportional.
The general formula for direct proportionality is
[tex]y=kx[/tex], where k is the constant of proportionality.
Taking into account the square root of x, we can use the following formula to find k by plugging in x and y:
[tex]y=k\sqrt{x}\\ 21=k\sqrt{49}\\ 21=7k\\3=k[/tex]
Since we found k, we can now use this value and the x we're given for the second part of the problem to find y:
[tex]y=3\sqrt{x} \\y=3\sqrt{144}\\ y=3*12\\y=36[/tex]
(Acceptance Sampling.) The following two acceptance rules are being con- sidered for determining whether to take the delivery of a large shipment of components: Rule 1. A random sample of ten components is checked, and the shipment is accepted only if none of them is defective. Rule 2. A random sample of twenty components is checked, and the ship- ment is accepted only if not more than one of them is defective. Which of these acceptance rules has the smaller probability of accepting a shipment containing 20% defectives?
we can see that Rule 2 has a higher probability of accepting a shipment containing 20% defectives. Therefore, Rule 2 has a smaller probability of accepting a shipment containing 20% defectives.
How to find Probability of acceptance?To compare the probabilities of acceptance of a shipment containing 20% defectives for the two rules, we can calculate the probabilities for both rules and compare the results.
Ac coding to data:For Rule 1, the probability of accepting a shipment containing 20% defectives is given by the probability of having 0 defectives in a sample of 10 components. This can be calculated as
P(Accept | 20% defectives) = (0.8)¹⁰
= 0.107374
For Rule 2, the probability of accepting a shipment containing 20% defectives is given by the probability of having 0 or 1 defectives in a sample of 20 components. This can be calculated as:
P(Accept | 20% defectives) = (0.8)²⁰ + ²⁰C₁ * (0.8)¹⁹ * (0.2)
= 0.276
Comparing the two probabilities, we can see that Rule 2 has a higher probability of accepting a shipment containing 20% defectives. Therefore, Rule 2 has a smaller probability of accepting a shipment containing 20% defectives.

m represents the slope.x and y are the points.From the information provided, an equation of the first line WX is given by;
y = x/5 - 2
Therefore, slope (m) = 1/5
In Mathematics, a condition that must be met for two lines to be perpendicular is given by:
m₁ × m₂ = -1
1/5 × m₂ = -1
m₂ = -5.
At point (-3, 1), an equation of the line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 1 = -5(x - (-3))
y - 1 = -5(x + 3)
y = -5x - 15 + 1
y = -5x - 14
