Answer: 410 possible points
To solve for the possible points in the course, use a proportion and cross multiply.
What is a proportion?
A proportion is two fractions that are equal to each other. For the fractions to be equal, they are proportionate. In our math problem, percentage is proportionate the the number of points.
The fractions represent information you have, and one variable will represent what you are solving for.
GivenYour points = 361
Points to get an 'A' = your points + 8
'A' = 90% of possible points
Find the points needed for an 'A' at 90%Points to get an 'A' = your points + 8
= 361 + 8
= 369
State variableslet x be the amount of possible points
Write a proportionWe know the number of points for 90% is 369 points. Remember that 90% is the same as 90/100.
Keep the information with the same units inside the same fraction. Here, percentage is represented by the first fraction. Points is represented by the second fraction.
[tex]\displaystyle{\frac{90}{100}=\frac{369}{x}}[/tex]
SolveWe can solve using cross multiplication. This is when we multiply each numerator by the denominator from the other fraction.
[tex]90x = 369*100[/tex] Simplify by multiplying.
[tex]90x = 36,900[/tex] Isolate the variable x.
[tex]\displaystyle{\frac{90x}{90} = \frac{36,900}{90}}[/tex] Divide both sides by 90 to cancel out 90 on the left.
[tex]\displaystyle{x = \frac{36,900}{90}}[/tex] Divide.
[tex]x = 410[/tex] Solved for x, representing the possible points.
∴ The possible points in the art course is 410.

one seventh times the absolute value of the quantity x minus 3 end quantity minus 2 equals 9
Answers
The solutions of "one seventh times the absolute values of the quantity x minus 3 minus 2 equals 9" is 80 and -74
The absolute value of the quantity x minus 3 = |x-3|
The one seventh time the absolute value of the quantity x minus 3 minus 2 equal to 9
Then the equation will become
(1/7)×|x-3|-2=9
Solve the equation
(1/7)×|x-3|-2= 9
(1/7)×|x-3|= 11
|x-3| = 11×7
|x-3|= 77
The absolute value equation will become
x-3= 77
x-3 = -77
Solve both equation
x-3=77
x= 80
x-3 = -77
x= -74
Hence, the solutions of "one seventh times the absolute values of the quantity x minus 3 minus 2 equals 9" is 80 and -74

Step-by-step explanation:
Angle sum of a triangle: [tex]< A + < B+ < C=180^o\\[/tex]
Types of Triangles: Isosceles, Equilateral, Scalene
Given AB = AC are two sides of the big triangle, then ΔABC is Isosceles.
Isosceles triangles are defined to have two equal sides and two equal angles (opposite the congruent(equal) sides).
Also, since ABC is defined as a triangle, BC is a straight line, a.k.a., it is a [tex]180^o[/tex] angle. As the image shows, the line, AD creates a right angle on one side, therefore it creates a right angle([tex]90^o[/tex]) on the other side.
Back to Isosceles Triangles, AD = AE means ΔADE is isosceles and <ADE = <AED
Using the Angle sum formula of a triangle, you can fill in <A, <B, and <C with the following:
<A=[tex]50^o[/tex]
<B=<C=y [This is because <ADE = <AED]
[tex]50^o+2y=180^o\\2y=130^o\\y=65^o[/tex]
Now, this means that <ADE=[tex]65^o[/tex] and <ADC =[tex]90^o[/tex]
<x is better seen as <EDC
<EDC+<ADE=<ADC
Since we know <ADE is 65 and <ADC is 90, we can plug in these to the formula above.
[tex]x+65^o=90^o\\x=25^o[/tex]

What is the triangle?Triangles are three-sided polygons with three vertices. The angles of the triangle are formed by connecting the three sides end to end at a point. The sum of the triangle's three angles equals 180 degrees. Every triangle has three sides and three angles, which may or may not be the same. In the case of a right triangle, the sides are given special names, with the side opposite the right angle being known as the hypotenuse and the other two sides being known as the legs.The range of possible distance from Aaron to Clara:
15+d > 8 ⇒ d > -78+d > 15 ⇒ d>715+8 > d ⇒ d < 23So, the range is: 7<d<23
Therefore, the range of possible distance from Aaron to Clara is 7<d<23.

How to find the length of the Mississippi River using the scale?The scale was 5 centimetres represents 120 miles.
Therefore, on the scale
5 centimetres = 120 miles
Now, let's find the length in centimetres if the river is measured as 2320 miles.

24 and 33 are the numbers among which 24 is the smallest.
Step-by-step explanation:
Let one positive integer be x, then another will be x - 9
Solve:
[tex]\sf \dfrac{x-9 }{x} = \dfrac{8}{11}[/tex]
cross multiply
[tex]\sf 11x-99= 8x[/tex]

The equation of the given function will be h=-0.096x+30.6. The mass will be 63.5 grams.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is y-intercept.
1.) The slope of the given function will be,
Slope = (25.8 - 30.6) / (50 - 0) = -4.8/50 = -0.096
Now, substitute the values in the general linear equation,
h = -0.096x + c
30.6 = -0.096(0) + c
c = 30.6
Therefore, the equation of the given function will be h=-0.096x+30.6.
2.) Mass when the height is given as 24.5 cm, will be,
h = -0.096x + 30.6
24.5 = -0.096x + 30.6
24.5 - 30.6 = -0.096x
-6.1 = -0.096x
x = -6.1/-0.096
x = 63.5
Hence, the mass will be 63.5 grams.

Choose the estimate closest to the length of a pen: 30cm, 160mm, or 16mm.
Answers
The estimate closest to the length of a pen is 160mm
How to estimate the closest length of a pen?Estimation is when we use approximate values in a calculation to give an approximate, predicted answer rather than an exact answer.
We can estimate some lengths and distances using approximate values for measurements.
For example, 16 cm is approximately the length of a pen.
Therefore, the estimate of a pen is 16 cm.
Since the length in cm is not in the option, we have to convert.
Hence,
1 centimetres = 10 millimetres
16 centimetres = ?
cross multiply
estimated length of a pen = 160 millimetres.
Therefore, the estimate closest to the length of a pen is 160mm

One way to simplify an expression containing trigonometric functions is to first write the expression in terms of sines and cosines only.
What is an expression?An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
The law of cosine.In order to determine the missing side length of a geometric figure with the adjacent and hypotenuse side lengths given, you should apply the law of cosine:
C² = A² + B² - 2(A)(B)cosθ
Similarly, the law of sine can be used to determine the missing side length of a geometric figure with the opposite and hypotenuse side lengths are given:
[tex]\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}[/tex]
In this context, we can reasonably infer and logically deduce that an expression containing trigonometric functions can be simplified by first writing the expression in terms of sines and cosines only.

The solution to the inequality is w ≥ 470 or w ≤ 530
How to determine the solution to the inequality?The given parameters are:
Number of words = 500
Absolute deviation = 30
Acceptable number of words = w
The absolute value inequality is represented as
|w - Number of words| ≥ Absolute deviation
So, we have
|w - 500| ≥ 30
Remove the absolute bracket
So, we have
w - 500 ≥ -30 or w - 500 ≤ 30
Add 500 to both sides of the inequality
So, we have
w ≥ 470 or w ≤ 530
Hence, the solution to the inequality is w ≥ 470 or w ≤ 530
