What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Lisa buy new clothes for spring under $200.00
She spent $125.88 for buying some shirts that has each cost $20.80.
Let the number of shirts = x
Then, We can formulate for the given condition is;
The inequality for solution of the value of x is,
⇒ $20.03x + $125.99 < $200.00
Because we can solve for x, which is the number of shirts Lisa can buy with the money she has left.
Therefore,
The correct inequality to solve for x will be;

The flag of Colombia is a rectangle that is 66 ft. long with three horizontal stripes
The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
Below is a scale illustration of the Colombian flag that ranges from 1 cm to 2 ft.
How are scale illustrations created?It is already stated that all measurements would be done using a fixed scale for a given scale drawing. Let the scale, for illustration, be K feet to s inches.
1ft ; s/k in
Thus, all foot measures will be multiplied by s/k to obtain the relevant lengths in the drawing.
Since the ratio is 2:1, there are 1 centimeter for every 2 feet.
This indicates that to reach 33, we must divide 66 by 2.
66/2 = 3
As a result, the scale drawing of the Colombian flag is attached below and has a scale of 1 cm to 2 ft.

Option 1. This is a vertical pair of angles because they are two nonadjacent (not next to each other) angles formed by intersecting lines. The sides of one angle are the opposite rays to the sides of the other angle. (Angle 5=Angle 7)
Option 2 and 4 are wrong as the angles are not created by a set of parallel lines and a transversal.
Option 3 is wrong as the angles are not adjacent.
Option 5 is wrong as the angles do not have a sum of 90°.

Select all ratios equivalent to 3:6
18:9. 4:8. 11:12
Answer:
4:8
Step-by-step explanation:
Equivalent ratios have the same simplified ratio.
The simplified ratio of 3:6 is 1:2. We can get it by dividing both sides of the ratio by a common factor of 3.
18:9 is incorrect because its simplified ratio is 2:1. Equivalent ratios have the same order.
4:8 is correct because dividing both sides of the ratio by 4 gives us 1:2.
11:12 is incorrect because it can not be simplified to give 1:2.

a license plate in a certain state consists of 4 digits, not necessarily distinct, and 2 letters, also not necessarily distinct. these six characters may appear in any order, except that the two letters must appear next to each other. how many distinct license plates are possible?
33,800,000 are total distinct six characters license plates possible such that the two letters must appear next to each other. We can solve it by using combination formula ( ⁿCr ) .
Total number of digits are 10 i.e., 0,1,2,3,4,5,6,7,8,9. We have given the option to select any four digits out of 10 with repetition. So, we use combination formula
ⁿ C r = n!/(r! ×(n-r)! )
For 1ˢᵗ digit, the number ways to choose the 1ˢᵗ digit is ¹⁰C ₁= 10
For 1ˢᵗ letter, the number of ways to choose the 1ˢᵗ letter is ²⁶C ₁= 26
There are 10×10×10×10 = 10⁴ ways to choose four digits . In a similar way, the total number of letters for choice is 26 ; i.e., from A to Z. We were given the task of choosing two letters from a list of 26 , which were not necessarily distinct .
There are 26×26 = 26²ways to choose the two letters . For the letters to be next to each other, they can be the 1ˢᵗ and 2ⁿᵈ, 2ⁿᵈand 3ʳᵈ, 3ʳᵈand 4ᵗʰ, 4ᵗʰand 5ᵗʰ, 5ᵗʰ and 6ᵗʰ characters . So, there are 6-1 = 5 are choices for the positions of the letters .
Therefore, numbers of distinct license plates is 5×10⁴× 26² = 33,800,000

ramone scores 40 on his history test and 40 on his chemistry test. the class means for both tests is 30. the standard deviation for the history test is 10 and the standard deviation for the chemistry test is 5. on which test did he do better in relation to his peers and why?
Ramones’s Chemistry test was much better as it has higher Z-Score than history
For History test, Test score (x) = 40
Mean (μₓ) = 30, Standard deviation (σₓ) = 10
For Chemistry test, Test score (Y) = 40
Mean (μ) =30, Standard deviation (σ) =5
Ramones’s Z-score for History test is given by,
Z-Score = (x-μₓ)/σₓ =(40-30)/10 = 1
Ramones’s Z-score for chemistry test is given by,
Z-Score = (y-μ)/σ =(40-30)/5 = 2
Thus, Ramones’s Chemistry test was much better, because Chemistry test has higher z-score.

Answer:
I'll do #17 as an example of how to do the others. #15 doesn't make sense. What is "= ≤⁄x?"
Step-by-step explanation:
17. (-3, 2); y=-4
y=4 is a horizontal line, where all values of y are 4, regardless of x. A horizontal line has a slope of 0. [Y does not depend on x].
That leaves us with y =0x + b
For this line to go through point (-3,2), it would have to have a y-intercept (b) of 2 [b is the value of y when x=0]. Since y=0 regardless of x, b must be 2.
The parallel line that goes through (-3,2) is:
y = 0*x + 2, or
y = 2

The ratio of r-32 to r-125 is 3:2
A ratio in math displays how many times one number is contained in another. Comparing two numbers by dividing them is how ratios work. Your formula would be A/B if you were contrasting one data point (A) with another data point (B). When both sides of a ratio are whole numbers and cannot be divided by a whole number, the ratio is in its simplest form.
Given,
Refrigerant r-32 and r-125 are the two main constituents of refrigerant r-410.
60 pounds of r-32 and 40 pounds of r-125 make up to 100 pounds of r-410.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.
We have been given two fractions.
The three containers have 3/4 pounds of sugar and fourth one have 1/2 pounds of sugar.
To find the total sugar, we have to add both the fractions
Total pounds of sugar = Sugar in three containers + sugar in fourth container
= 3/4 + 1/3

To understand the equation, you must first know that m∠a = 108°. It equals that because a regular five-sided polygon has an interior angle of 108° each.
Next, you would want to group all constants to the right side of the equation. By doing so, you want to subtract 72 from both sides.
(3z + 72) - 72 = 108 - 72

After 10 years, the car will be worth 0.54 of the price when Rob purchases it. The result is obtained using the exponential depreciation equation.
How to calculate depreciation?The depreciation can be calculated by the exponential depreciation equation.
y = P (1 - r)ˣ
Where
y = the value after a period of yearsP = the original valuer = the depreciation ratex = the number of periodeIf given
r = 6%x = 10 yearsHow much will the car be worth after 10 years?
The depreciation rate would be
r = 6%
r = 6/100
r = 0.06
So, after 10 years, the car would be worth
y = P (1 - r)ˣ
y = P (1 - 0.06)¹⁰
y = P (0.94)¹⁰
y = P (0.54)
