The reason why partitioning and fractioning are different is because; The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4.
Why is partitioning different from fractioning?It follows from the task content that a close analysis of the statement of ratios; 1:3 implies that the whole is divided into four parts; 1+3 = 4.
On the contrary, one-third simply means 1 out of 3 equal parts of the line.

Simplify the expression to a polynomial in standard form:
(−x+1)(x^2+6x−4)
Answer:
-x^3-5x^2+10x-4
Step-by-step explanation:
(−x + 1) (x ^ 2 + 6x − 4) = (-x)(x ^ 2 + 6x − 4) + 1(x ^ 2 + 6x − 4)

Solve the system of equations using substitution.
y = -2X +1
4x + 2y = -2
Answer:
Step-by-step explanation:
4x + 2(-2X +1) = -2
Order of operations -
4x + -4x +2 = -2
Combine terms
4x-4x=0x
2 = -2
Answer:
no solution
Step-by-step explanation:
y = - 2x + 1 → (1)
4x + 2y = - 2 → (2)
substitute y = - 2x + 1 into (2)
4x + 2(- 2x + 1) = - 2 ← distribute parenthesis and simplify left side
4x - 4x + 2 = - 2 ( subtract 2 from both sides )
0 = - 4 ← not possible

Consider the set of real numbers and the set of complex numbers. Is every real number also a complex number? Is every complex number also a real number? Explain.
You define complex numbers as the reals, i, as usually defined, and their linear combinations using real coefficients, then,
The reals are complex numbers, even if you haven’t fully defined their properties.
If you define complex numbers as the form (a,b) with and a, b are real numbers, then you can say that each real number a is isomorphic with that complex number,
if b=0 once you define their properties.
What is the complex number?A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane.
Of course, (0,1) will be i. You’ll have to define the multiplication rule, etc.
In actual usage, we gloss over the distinction, and real numbers are complex numbers with no imaginary part.

Answer:
(4,6)
Step-by-step explanation:
To calculate the midpoint of two points, just calculate the arithmetic mean (average) of the x and y values of the two points given. For example, it is easy to see visually that the midpoint of (2, 0) and (4, 0) is (3, 0), since (3,0) falls right in the middle of the two points. However, the way to calculate this would be to take the average of 2 and 4 (3), along with the average of 0 and 0 (0). This process gives us our new point (3, 0). In case this doesn't make sense, here is the formula for the midpoint of two points - (x1,y1) and (x2,y2):
[tex]M=(\frac{x1+x2}{2},\frac{y1+y2}{2} )[/tex]
For this problem, E is (2,4) and F is (6,8). So, the midpoint would be:
[tex](\frac{2+6}{2},\frac{4+8}{2})=(\frac{8}{2},\frac{12}{2})=(4,6)[/tex]
Therefore, the midpoint is (4,6)

At a Phil's Cafe, a dinner meal is made up of an appetizer, a main course, a dessert and a drink. The choices for the appetizer are soup or salad; for the main course are chicken, fish, steak or lobster; for the dessert are ice cream, pie, sorbet, or a pastry; the drinks are coffee, tea or milk. How many different dinner meals are possible
The number of different meals possible is 96, computed using combinations.
The combination is a method of choosing a number of articles from a larger set of articles in no particular order.
In the question, we are asked about the different dinner meals possible when a dinner meal is made up of an appetizer, a main course, a dessert, and a drink.
The choices for the appetizer are soup or salad, so the number of ways of choosing an appetizer = 2C1 = 2.
The choices for the main course are chicken, fish, steak, or lobster, so the number of ways of choosing a main course = 4C1 = 4.
The choices for the dessert are ice cream, pie, sorbet, or pastry, so the number of ways of choosing a dessert = 4C1 = 4.
The choices for the drink are coffee, tea, or milk, so the number of ways of choosing a drink = 3C1 = 3.
The total number of ways is the product of all of them.
Therefore, the total number of ways = 2*4*4*3 = 96.
The number of different meals possible is 96, computed using combinations.

Pls help me I got it wrongg :((
Answer:
4 ounces
Step-by-step explanation:
I'm assuming when it says: [tex]33\frac{1}{3}%[/tex]% it means 33.3333333333 instead of 33/3.
Anyways under that assumption, we currently have 20 ounces in the grape juice, since 4 ounces is grape juice concentrate and 16 ounces is water. So currently let's just say that the total amount of grape juice concentrate is going to be: [tex](4+x)[/tex] where x is the amount of grape juice concentrate you need to add to make it 33.33%. The next thing to know is how to calculate how much percent a is of b. This can be calculated using the equation: [tex]\frac{a}{b}*100[/tex]. So in this case the a is going to be the grape juice concentrate, and the b is going to be the entire mixture (water and grape juice). Since the concentrate is having x added to it, that means the entire thing is also having x added to it. This means we have the equation: [tex]\frac{4+x}{20+x} * 100[/tex], since we already have 4 ounces of grape juice concentrate, and we already have 20 ounces in total (16 ounces of water + 4 ounces of grape juice). This is going to be equal to 33.33%, or in other words 33 1/3. So to make this a bit easier, I'm going to convert this mixed fraction into one fraction, this gives you the fraction: [tex]\frac{100}{3}[/tex]. So now that's all left to do is set these two expressions equal to each other and solve for x
Original equation
[tex]\frac{4+x}{20+x}*100=\frac{100}{3}[/tex]
Divide both sides by 100
[tex]\frac{4+x}{20+x}=\frac{100}{3}\div 100[/tex]
Keep fraction, change division to multiplication, flip 100
[tex]\frac{4+x}{20+x}=\frac{100}{3}* \frac{1}{100}[/tex]
The 100 in the numerator will cancel out the one in the denominator
[tex]\frac{4+x}{20+x}=\frac{1}{3}[/tex]
Multiply both sides by 20+x
[tex]4+x=\frac{20+x}{3}[/tex]
Multiply both sides by 3
[tex]3(4+x)=20+x[/tex]
Distribute the 3
[tex]12+3x=20+x[/tex]
Subtract x from both sides
[tex]12+2x=20[/tex]
Subtract 12 from both sides
[tex]2x=8[/tex]
Divide both sides by 2
[tex]x=4[/tex]
So Kahn needs to pour 4 more ounces of grape juice, to double check this, since the mixture already has 4 ounces of grape juice, this means the final mixture will have a total of 8 ounces of grape juice concentrate, and a total of 24 ounces, since it already had 16 ounces of water, and 4 ounces of grape juice and now there is 4 more ounces of grape juice being added, so a total of 24 ounces. this means that 8/24 will be grape juice concentrate or in other words: [tex]\frac{1}{3}[/tex] and when you multiply this by 100 (to convert to percent), you get 100/3 or 33 1/3%

A basketball hoop is shown. Lisa is standing 10 feet from the basketball net. The basketball net is 8.5 feet high. Lisa apostrophe s line of vision is 5 feet off the ground. When she looks up to the net, a right triangle is formed.
Use the diagram and complete the steps to find the measure of the angle of depression from the top of the hoop to Lisa.
The length of the shortest leg of the right triangle that is formed is
feet.
The angle of depression from the hoop to Lisa is
to the angle of elevation from Lisa’s line of sight to the hoop.
Because the lengths of the opposite and adjacent sides are known, use the
function.
The angle of depression, rounded to the nearest degree, is approximately
degrees.
By critically observing the basketball hoop (see attachment), we can logically deduce that the basket's height from Lisa's horizontal sight is the same as the length of the shortest leg of the right-angle triangle:
Shortest leg = 8.5 - 5
Shortest leg = 3.5 feet.
In Geometry, the sum of all the angles in a triangle is equal to 180°:
x + y + z = 180
x + y + 90 = 180
x + y = 180 - 90
x + y = 90° (complementary angle).
Therefore, the angle of depression is complementary to the angle of elevation.
Also, you should use the inverse tangent function because the lengths of the opposite and adjacent sides of the right-angle triangle are known.
How to find the angle of depression?Angle of depression = tan⁻¹(Opposite/Adjacent)
Angle of depression = tan⁻¹(3.5/10)
