Answer:
Percent:
There are many formulas for percentage problems. You can think of the most basic as X/Y = P x 100. The formulas below are all mathematical variations of this formula.
X and Y are numbers and P is the percentage:
Find P percent of X
Find what percent of X is Y
Find X if P percent of it is Y
Mixture:
Solving a percent mixture problem can be done using the equation Ar = Q, where A is the amount of a solution, r is the percent concentration of a substance in the solution, and Q is the quantity of the substance in the solution.
Proportion:
Many "proportion" word problems can be solved using other methods, so they may be familiar to you. For instance, if you've learned about straight-line equations, then you've learned about the slope of a straight line, and how this slope is sometimes referred to as being "rise over run". But that word "over" gives a hint that, yes, we're talking about a fraction. And this means that "rise over run" can be discussed within the context of proportions.

Write an equation of the line that passes through (0,4) and (0,-3).
Answer:
It is a vertical line at x = 0
Step-by-step explanation:
An equation of a line in a slope-intercept form is y=mx+b
So with the coordinates given, we must find the slope (m), and the y-intercept (b).
In order to find the slope using these coordinates,
we have to use the formula (y2-y1)/(x2-x2).
So the slope would be -3 - 4 / 0.
Because the denominator is 0, the slope would be undefined.
It is easier to see the equation/graph by graphing the coordinates on the coordinate plane. You will see that it is a straight vertical line down x=0.
Hello there! :)
We can use the formula:
[tex]\frac{y2-y1}{x2-x1} \\[/tex]
First, let's take a look at the x-coordinates. They are the same, aren't they?
If the x-coordinates are the same, then the slope is undefined.
Put the x-coordinates into the formula. It turns out that we divide by 0, and division by 0 is undefined.

Find the greatest common factor of 50,75, and 150
Answer: 25
Step-by-step explanation:
To find the greatest common factor of an number, you start by listing the factors of each number. The factor that appears the greatest amount of times is the greatest common factor.
175: 1,5,7,25,35,175.
75: 1,3,5,15,25,75.
25:1,5,25.
The number 25 in this case appears the most frequently, therefore the answer is 25.
The greatest common factor (GCF), of the given numbers 50, 75, and 150 is 25.
To find the GCF, we identify the common factors of the given numbers and then select the largest one. The common factors of 50, 75, and 150 are the numbers that divide each of them without leaving a remainder.
In this case, 25 is the largest number that divides all three numbers evenly.
50 = 2 × 5 × 5
75 = 3 × 5 × 5
150 = 2 × 3 × 5 × 5
Since 25 is present as a factor in all three numbers, it's the greatest common factor.
Therefore, The GCF of 50, 75, and 150 is 25.

Write a quadratic function whose zeros are -12 and -2.
Answer:
(x+12) (x+2)
x(x+12)+2(x+12)
x^2+12x+2x+24
x^2+14x+24
Step-by-step explanation:
Answer:
f(x) = x² + 14x + 24
Step-by-step explanation:
Given the zeros of -12 and -2, then it means that:
x + 12 = 0 and x + 2 = 0
As a proof, if you isolate x, you'll end up with the given values:
x + 12 - 12 = 0 - 12
x = -12
x + 2 - 2 = 0 - 2
x = -2
In terms of using these values into the quadratic function:
(x + 12) (x + 2)
Perform the FOIL method in order to find the quadratic function:
(x + 12) (x + 2)
f(x) = x² + 2x + 12x + 24
f(x) = x² + 14x + 24 ⇒ This is the quadratic function, given the zeros as x = -12, and x = -2.

ANSWER:
1 : 14
EXPLANATION:
1) Convert 1 meter to centimeters.
7 cm : 100 cm
2) Now you just simplify both sides (divide 7 by 7 to get 1 and then you have to divide 100 by 7 as well).
[tex]\frac{7}{7}=1[/tex]
[tex]\frac{100}{7}=14.285[/tex]
Therefore, the ratio is:
1 : 14
Consider the equation below. The value of x in terms of h is . The value of x when h = 4 is .
The value of x when h = 4 is 4.
The given equation is : 4(x − 3) = h. We need to find the value of x in terms of h and the value of x when h = 4.So, we will solve this equation by following the steps given below:
Step 1: Distribute 4 by x and 4 by -3. It gives us:4x - 12 = h
Step 2: Add 12 to both sides of the equation. We get:4x - 12 + 12 = h + 124x = h + 12
Step 3: Divide both sides of the equation by 4. We get:x = (h + 12) / 4
Therefore, the value of x in terms of h is x = (h + 12) / 4.
Now, we need to find the value of x when h = 4. We will put h = 4 in the above equation and get the value of x.x = (4 + 12) / 4 = 16 / 4 = 4.

Use the IQR to determine if any of the data in the data set are outliers.
{23,80,43,23,0,20,23,23,20,28}
Using the IQR, the only outlier in the data set is: 0.
What is the IQR of a Data Set?IQR = upper quartile (Q3) - lower quartile (Q1).
Given the data set, 23,80,43,23,0,20,23,23,20,28:
Quartile (Q1): 20
Quartile (Q3): 31.75
IQR = 31.75 - 20 = 11.75
The outliers are data values that lie below:
Q1 - (1.5 × IQR) = 20 - (1.5 × 11.75) = 2.375

According to a study, 15 out of 50 adults have allergies. What percentage of adults do not have allergies?
Answer:
70% of adults do not have allergies.
Step-by-step explanation:
It states that 35 out of 50 adults do not have allergies. If we turn this into a fraction (35/50), we can then multiply the denominator by 2 to make it 100. We would then also multiply the numerator by 2.
35 x 2 =70
70/100 = .7
.7 is just the decimal form of 70%

What is the value of x which proves that the runways are parallel? What is the measure of the larger angle?
Answer:
118°
Step-by-step explanation:
When two parallel lines are cut by a tranversal, then the exterior angles are supplimentary and the corresponding angles are congruent.
Therefore the angle above (15x - 17)° is also (5x + 17)° and the angle below (5x + 17)° is also (15x - 17)°.
Angles on a straight line adds up to 180°. So to know the measure of the larger angle we must both equations and equal it to 180° to find x in order to know the larger angle.
(5x + 17) + (15x - 17) = 180
5x + 15x + 17 - 17 = 180
20x = 180
20x/20 = 180/20
x = 9°
Nkw let's substitute x = 9 into the equations
5x + 17 =
5(9) + 17 =
= 62°
15x - 17 =
15(9) - 17 =
= 118°
Both equations should add up to be 180°.
Therefore the measure of the largest angle is 118°.
Find the length of x of the side of the larger triangle. (Assume that the two triangles are similar, and use the fact that corresponding sides of similar triangles are proportional)
X=
Similar triangles may or may not be congruent
The value of x that makes both triangles similar is 4.5
The equivalent ratio of both triangles is:
[tex]\mathbf{2 : 1 = 9 : x}[/tex]
Express the above equivalent ratio as a fraction
[tex]\mathbf{\frac 12= \frac x9 }[/tex]
Multiply both sides of the fraction by 9
[tex]\mathbf{\frac 12\times 9 = \frac x9 \times 9 }[/tex]
Cancel out common factors
[tex]\mathbf{\frac 12\times 9 = x}[/tex]
Divide 12 by 9
[tex]\mathbf{4.5 = x}[/tex]
Rewrite the above expression as:
[tex]\mathbf{x = 4.5 }[/tex]
Hence, the value of x is 4.5
