Answer:

Step-by-step explanation:
You can use Desmos a free graphing calculator to do this.
Mrs. Chu is ordering senior portraits of her son to send to their relatives. A medium photo
costs $22 and a large photo costs $42. She wants to spend less than $400 in total.
Select the inequality in standard form that describes this situation. Use the given numbers
and the following variables.
x = the number of medium photos
y = the number of large photos
The inequality which represents the situation is 22x + 42y < 400.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given,
Cost of medium photos = 22x
Cost of large photo = 42y
Total cost < 400
22x + 42y < 400
Hence "The scenario is represented by the inequality 22x + 42y < 400.".

0.09 (100n + 1) = 0.3 (n +9)
Answer:
n = 0.3
Step-by-step explanation:
0.09(100n + 1) = 0.3(n + 9) ← distribute parenthesis on both sides
9n + 0.09 = 0.3n + 2.7 ( subtract 0.3n from both sides )

What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that

The standard deviation provides insight into the distribution of values around the mean. If the standard deviation is small, in general, the more narrow the range between the lowest and highest value. That is, values will cluster close to the mean. From your descriptive statistics, describe the standard deviations of salary, hrly rate, yrs worked, education, and age. What does this tell you about the variables
The standard deviation gives information about how values are distributed around the mean. The range between the lowest and highest number is more constrained when the standard deviation is low. Values will so tend to group together around the mean.
What is explained by the standard deviation?
The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.
When comparing data sets that may have the same mean but a different range, it is helpful. The mean of the following two numbers, for instance, is the same: 15, 15, 15, 14, 16 and 2, 7, 14, 22, 30.

write in slope-intercept form of the line that passes through the points (-2,-2) and (5,12)
To write the equation of a line in slope-intercept form (y = mx + b), we need to find the slope of the line (m) and the y-intercept (the point where the line crosses the y-axis, which is represented by b).
We can use the point-slope formula to find the equation of the line that passes through the points (-2,-2) and (5,12):
y - y1 = m(x - x1)
Where (x1, y1) is a point on the line, and m is the slope of the line.
Plugging in the values for the given points and solving for m, we get:
m = (12 - (-2)) / (5 - (-2))
= 14 / 7
= 2
Now that we have the slope, we can use either of the given points to find the y-intercept (b). Let's use the point (-2,-2):
y = mx + b
-2 = 2(-2) + b
-2 = -4 + b
b = -2 + 4
b = 2
Therefore, the equation of the line in slope-intercept form is:
y = 2x + 2
This is the equation of the line that passes through the points (-2,-2) and (5,12).

In △QRS , point A is between points Q and R, point B is between points R and S, and AB∥QS .
QA=23 cm , QR=41 cm , and RS=123 cm .
What is RB ?
Answer:
the length of RB is 18 cm.
Step-by-step explanation:
In △QRS, since point A is between points Q and R, and point B is between points R and S, we have that QR > QA > 0 and RS > RB > 0. Additionally, since AB∥QS, we know that the segment AB is parallel to the segment QS.
We can use this information to set up an equation to solve for RB. Since AB∥QS and QA = 23 cm, we have that QR = RB + 23. We can substitute this expression into the equation QR = 41 cm to get:
RB + 23 = 41
Solving this equation for RB, we get:
RB = 41 - 23
Therefore, the length of RB is 18 cm.

What are different operations in maths?The fundamental procedures for altering and combining mathematical objects, such as integers and functions, are known as operations in mathematics. These operations, which are used to carry out mathematical computations on numbers, generally include sum, subtraction, multiplication, and division. Operations may also be applied to other types of mathematical objects, like as vectors, matrices, and sets, to execute more sophisticated operations such as vector addition, matrix multiplication, and set intersection. The outcome of an operation is referred to as an operand, and the procedures for combining operands are referred to as the operation's laws. A basic idea in mathematics, operations are applied in many different areas of science and math.
How to solve?

21 miles per hour is the speed of boat still in water and 9 miles per hour is the speed of current.
What is downstream speed and upstream speed?Downstream - A boat is said to be moving downstream if it is moving in the same direction as the stream.
Upstream - A boat is said to be moving upstream if it is moving downstream of the stream. The term "upstream speed" in this context refers to the boat's net speed.
13) Given that, a boat traveled 280 miles downstream and back.
Time taken by boat in downstream is 7 hours and in upstream is 14 hours.
Let the speed of a boat be x miles per hour and the speed of a current be y miles per hour.
So, the total speed in downstream is x+y miles per hour and the total speed in upstream is x-y miles per hour.
We know that, Distance = Speed × Time
Now, 280=(x+y)×7
⇒ x+y=40 ------(I)
Here, 280=(x-y)×14
⇒ x-y=20 ------(II)
Add equation (I) and (II), we get
x+y+x-y=40+20
⇒ 2x=60
⇒ x=30 miles per hour
So, x+y=40
⇒ y=10 miles per hour
14) Given that, a boat traveled 252 miles downstream and back.
Time taken by boat in downstream is 12 hours and in upstream is 84 hours.
Let the speed of a boat be p miles per hour and the speed of a current be q miles per hour.
So, the total speed in downstream is p+q miles per hour and the total speed in upstream is p-q miles per hour.
We know that, Distance = Speed × Time
Now, 252=(p+q)×12
⇒ x+y=21 ------(I)
Here, 252=(p-q)×84
⇒ p-q=3 ------(II)
Add equation (I) and (II), we get
p+q+p-q=21+3
⇒ 2p=24
⇒ p=12 miles per hour
So, p+q=21
⇒ q=9 miles per hour
Therefore, the speed of boat still in water is 21 miles per hour and the speed of current is 9 miles per hour.

What is circumcenter ?the middle of the triangle's circle. It is the intersection of the "perpendicular bisectors," or lines that are perpendicular to the middle of each side.
Triangle ABC's circumcenter is the point at which any two perpendicular bisectors of any two sides of the triangle come together.
The perpendicular bisector of sides B(3,0) and C(3,2) has the equation is y=1.
Because AB's slope is unknown and its midpoint is at 3,1. The slope of the perpendicular bisector is zero. Such a line has the equation y=y1.
Additionally, x=1.5 is the equation for the perpendicular bisector of A(0,0) and B(3,0). The explanation is because AB has a zero slope and a midway of (1.5,0). The slope of the perpendicular bisector will be ill-defined. x=x1 is the equation for such a line.
