There is a solution to the system of equations, and Brianna and Ahmed paid the same price for the items.
What is the system of equations?
A system of equations is a set of one or more equations that are to be solved simultaneously. The solution to a system of equations is the set of values for the variables that satisfy all the equations in the system.
In this case, the system of equations represents the amount that Brianna and Ahmed paid for 5 paintbrushes and 3 art canvases, and 10 paintbrushes and 6 art canvases, respectively. The system of equations is:
5x + 3y = 47 (Brianna's purchase)
10x + 6y = 94 (Ahmed's purchase)
To determine whether Brianna and Ahmed paid the same price for the items, we can compare the value of x and y that satisfy both equations. To do this, we can solve the system of equations using any method we prefer, such as elimination or substitution. Here, we'll use the method of substitution:
From the first equation, we can solve for y in terms of x:
5x + 3y = 47
3y = 47 - 5x
y = (47 - 5x)/3
Substituting this expression for y into the second equation, we get:
10x + 6y = 94
10x + 6((47 - 5x)/3) = 94
Simplifying, we get:
10x + 94 - 10x = 94
94 = 94
This equation is always true, regardless of the value of x.
Therefore, there is a solution to the system of equations, and Brianna and Ahmed paid the same price for the items.

If a person is between one and seven days late paying tax, they are charged an extra 1% on the amount owed. If a person is over seven days paying tax, they are charged an extra 4% on the total amount owed ( including the extra 1% for being one to seven days late ). Calculate how much Amelia must pay if she owes $2375 and she pays it 10 days late.
Answer:
$2470
Step-by-step explanation:
If a person is between one and seven days late paying tax, they are charged an extra 1% on the amount owed. If a person is over seven days paying tax, they are charged an extra 4% on the total amount owed ( including the extra 1% for being one to seven days late ). Calculate how much Amelia must pay if she owes $2375 and she pays it 10 days late.
If Amelia owes $2375 and is 10 days late in paying her taxes, she will be charged an extra 4% on the total amount owed, which is $95. This is calculated by adding the 1% late fee for being 1 to 7 days late ($23.75) to the extra 4% late fee for being over 7 days late ($71.25) to get a total late fee of $95. Therefore, Amelia's total payment will be $2470.
Are the two triangles similar?
Yes or no?
How do you know? I
Yes, the two triangles are similar because they have equal angles.
What are similar triangles?Two objects are similar if they have the same shape, or if one has the same shape as the mirror image of the other. More precisely, one can be obtained from the other by uniformly scaling.
Two triangles are similar if their corresponding angles are equal and their corresponding sides are within the same ratio (or proportion). Similar triangles will have the same shape, but not necessarily the same size.
The missing side of the first triangle is 180-(111+24)
= 180-135

A random experiment consists of tossing a fair six-sided die repeatedly. How many tosses are required to be certain that the probability that at least one '6' appears is greater than or equal to 1/2?
I keep getting 3 from 1/6+1/6+1/6=1/2, it says the correct answer is 4.
We need at least 5 tosses to be certain that the probability of getting at least one 6 is greater than or equal to 1/2.
The probability of not getting a 6 on a solitary throw of a fair six-sided kick the bucket is 5/6. Subsequently, the probability of not getting a 6 on n throws is [tex](5/6)^n[/tex]. The probability of getting somewhere around one 6 in n throws is 1 - [tex](5/6)^n[/tex].
To view the quantity of throws expected as sure that the probability of getting somewhere around one 6 is more prominent than or equivalent to 1/2, we can set the probability equivalent to 1/2 and address for n:
1 - [tex](5/6)^n[/tex] = 1/2
[tex](5/6)^n[/tex] = 1/2
Taking the normal logarithm of the two sides, we get:
n ln(5/6) = ln(1/2)
n = ln(1/2)/ln(5/6) ≈ 4.807
Hence, we really want something like 5 throws to be sure that the probability of getting no less than one 6 is more prominent than or equivalent to 1/2.

a 25 foot ladder is leaned against the side of a building 2 feet from the base of the building. how far up the wall does the ladder reach and what is the angle of elevation for the ladder both to the nearest tenth?
Answer:
The ladder reaches up to 23.2 feet up the side of the building and the angle of elevation is 78.7 degrees to the nearest tenth. To calculate these values, you can use the Pythagorean Theorem. Let x be the distance the ladder reaches up the wall, and let y be the distance from the base of the building to where the ladder is leaning against the wall. Then, the Pythagorean Theorem states that x2 + y2 = 252, or x2 = 252 - y2. Since y = 2, then x2 = 252 - 22 = 676. Solving for x gives us x = 26, so the ladder reaches up to 26 feet. To calculate the angle of elevation, we can use trigonometry. We know that the opposite side is 26 feet and the adjacent side is 2 feet, so by using the tangent function, we can calculate the angle of elevation as tan-1(26/2) = 78.7 degrees.

A circle is centered at the origin, and point (9,−12)
lies on the circumference of the circle. Which two points also lie on the circumference of the circle
The two points that also lie on the circumference of the circle are approximately (-9.2, -12.5) and (11.8, -7.1).
Describe circumference of the circle?The circumference of a circle is the distance around its outer edge, also known as its perimeter. It is a key measurement in geometry, and is defined as the product of the circle's diameter and pi (π), a mathematical constant approximately equal to 3.14.
The formula for the circumference of a circle is:
C = 2πr
where C is the circumference, r is the radius of the circle, and π is the mathematical constant pi.
C = πd
The circumference of a circle is proportional to its radius or diameter, which means that if you double the radius or diameter of a circle, its circumference will also double. This relationship is fundamental to many mathematical and scientific applications, such as calculating the area or volume of a circle or sphere.
The circumference of a circle can be measured using a variety of tools, including rulers, compasses, and string. In practice, it is often measured indirectly by measuring the diameter or radius of the circle and using the formula above to calculate its circumference.
In summary, the circumference of a circle is the distance around its outer edge or perimeter, and is calculated using the formula C = 2πr or C = πd. It is a key measurement in geometry and has many practical applications in mathematics, science, and engineering.
To find two more points on the circumference of the circle, we can use the fact that the distance between the center of the circle and any point on its circumference is equal to the radius of the circle.
The radius of the circle can be found using the distance formula, which gives:
radius = sqrt((9-0)^2 + (-12-0)^2) = sqrt(225) = 15
So the circle has a radius of 15.
Now, to find two more points on the circumference, we can use the fact that any point on the circle can be represented as (r cos θ, r sin θ), where r is the radius of the circle and θ is the angle that the line connecting the point and the origin makes with the positive x-axis.
Since we already know one point on the circle, (9,-12), we can find the angle θ that this point makes with the positive x-axis by using the inverse tangent function:
θ = arctan(-12/9) = -53.13 degrees (or -0.93 radians)
Now we can find two more points on the circle by adding or subtracting multiples of 360 degrees (or 2π radians) to the angle θ and using the formula (r cos θ, r sin θ). For example:
Point (15 cos (-53.13), 15 sin (-53.13)) ≈ (-9.2, -12.5)
Point (15 cos (306.87), 15 sin (306.87)) ≈ (11.8, -7.1)
Therefore, the two points that also lie on the circumference of the circle are approximately (-9.2, -12.5) and (11.8, -7.1).

Answer:
This pair of equations is solvable by substitution, as I can easily substitute for y because it is already isolated in both equations. After substituting for y, I will solve the equations to get the value of x and then substitute that x-value into the simpler of the two equations, y = x - 1. Once I have both the x-value and y-value, they will be put into a point (x,y).
y = 3x + 3
y = x - 1
x - 1 = 3x + 3
x = 3x + 4
-2x = 4
x = -2
y = x - 1
y = ( -2 ) - 1
y = -3
The final answer to the pair of inequalities is ( -2,-3 )
Step-by-step explanation:
y = 3x + 3
y = x - 1
"substitution" means we are defining one variable by an expression of the other variable and use this identity in one of the original equations.
in our case here the main work was already done (even twice) : y is defined as expressions in x.
we even have the luxury to pick which one and then to use it in the other.
it does not matter which one you pick, it will lead to the same result.
so, let's use the identity of equation 1 in equation 2 : we replace every occurrence of y by the defined identity
y = x - 1
turns into
3x + 3 = x - 1
now we subtract x from both sides
3x + 3 - x = x - 1 - x
2x + 3 = -1
now we subtract 3 from both sides
2x + 3 - 3 = -1 - 3
2x = -4
and finally we divide both sides by 2
2x/2 = -4/2
x = -2
this result we use now in one of the original equations to get y :
e.g.
y = x - 1
y = -2 - 1 = -3
so, the solution is (-2, -3)

If WY and XZ are the diagonals (I think they are), then the equation to find it is 16x + 2 = 36x - 6 --> 8 = 20x --> x = 0.4
16(0.4) + 2 = WY = XZ --> 6.4 + 2 = 8.4 are the diagonal lengths.
Your weight on planets different is affected by gravity 50 £ 55 pounds on Mars the same ways only to 24 pounds on the moon what percent of an object earth weight is it weight on mars and
on the moon
Answer:
Assuming the weight of the object on Earth is 100 pounds, its weight on Mars would be:
(50 / 100) x 100 = 50 pounds
So the weight of the object on Mars is 50% of its weight on Earth.
Similarly, the weight of the object on the moon would be:
(24 / 100) x 100 = 24 pounds
So the weight of the object on the moon is 24% of its weight on Earth.

How to write the required linear inequality?In order to write a linear inequality to describe this situation, we would assign variables to the number of books and the number of hours respectively, and then translate the word problem into algebraic equation as follows:
Let the variable x represent the number of hours.Let the variable x represent the number of books.Since this printer makes more than three (3) copies of book every hour, a linear inequality which models or represents this situation is given by:
y > 3x
When the number of hours, x = 4 hours, the number of books made can be calculated as follows;
y > 3x
y > 3(4)
y > 12.

The correct answer is C. The Mode.
What is data in math?Data is the collection of data term that is organized and formatted in a specific way it's typically contains fact observation or statistics that are collected through a process of measurement or research data set can be used to answer question and help make informed decision they can be used in a variety of ways such as to identify trends on cover patterns and make prediction.
This measure of centre is most meaningful when the data is qualitative because it shows the value that appears most frequently in the data set. The mode can be used to identify the most popular item or most commonly occurring outcome. It is the only measure of centre that can be used for qualitative data, as the other measures (mean, median, and range) require numerical data.

I don't know how to write the symbols from the equation but I have included the photo.
Answer:
Quadrant III, sin θ = -12/13
Step-by-step explanation:
To solve this problem we can look at a unit circle (attached below). We can observe the following about the quadrants:
cos θ = 5/13 falls into the first OR fourth quadrant since cos (67) = 5/13 (roughly, obtained with inverse cosine function). However, we also have the restriction that sin θ < 0, therefore the quadrant that cos θ falls into is the fourth quadrant.
To find sin θ we first consider that cosine is adjacent over hypoteneuse. So, a = 5 and h = 13. Using pythagorean theorem we find that o (opposite) is equal to 12. Since sine is opposite over hypoteneuse we have:
sin θ = ±12/13
We use the plus or minuse sign because sin θ maps to both a positive and negative value, even though we used a geometrical approach, we still have to consider this. Of course, we know that sin θ has to be negative (given in the problem) so sin θ is -12/13.
