The inequality that represents Kenny's situation is 25x ≤ 500 − 200
What is inequality ?In mathematics, inequality is describe about the relative size or order of two values.
It states that one value is either greater than, less than, or not equal to the other value.
It is usually represented by symbols such as > (greater than), < (less than), ≥ (greater than or equal to), ≤ (less than or equal to), and ≠ (not equal to).
In this question ,
Let x be the number of basketballs Kenny needs to buy.
The inequality that represents Kenny's situation is:
25x ≤ 500 − 200
This inequality states that the total cost of purchasing the basketballs (25x) must be less than or equal to the available balance minus the desired amount after purchase (500 − 200 = 300).

Yes , it is a average rate of change over the interval -1
What is average rate of change?
It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.
suppose function y = x+1
then at interval [ -1 , 1]

Solve the following equation, explaining what you did in each step of your solution. After solving the equation, show the steps to check your solution. 3x + 2(4 + 6x) = 113
The solution to 3x + 2(4 + 6x) = 113 is x=7
3x + 2(4 + 6x) = 113
We will multiply the 2 with the brackets
3x+8+12x=13
adding the coefficients os x together
15x+8=113
adding -8 on both the sides
15x=105
dividing both the sides by 15
x=105/15
after division we get
x=7
To check our solution
we first put value of x in our original equation
3x7 + 2(4 + 6x7) = 113
we simplify the equation
21+2(4+42)=113
According to BODMAS we first solve the bracket
21+2(46)=113
now we solve the multiplication part
21+92=113
solving this
113=113
∴ LHS=RHS
Hence the solution is correct.
Therefore, the solution to 3x + 2(4 + 6x) = 113 is x=7

A picture of a bottle is 1/8 of its actual size.
The height of the bottle is 3 cm in the picture.
What is the actual height of the bottle?
Answer:
the actual size is 24 cm
Step-by-step explanation:
first, the problem tells us that the picture is only 1/8th of the original. the easiest way to find this is by thinking about the fact that we only have 1 out of 8 parts. each of these parts are going to be the exact same size.
each of the 8 parts is going to equal 3cm. so multiply 3 cm by your 8 parts.
3*8=24
this will give you the size of your entire bottle.
when using the some rule ,we only use two of the equal ratios at one time.That is we work with pairs of _____ sides and angle?
When applying the some rule, we only combine two equal ratios at once. Consequently, we deal with pairs of sides and angles that have equivalent ratios.
Which set of ratios form a proportion?When two ratios are equal, a percentage is formed; alternatively, two equal ratios can be said to produce a proportion. When we understand that two ratios are equal, you can write a proportion. The ratios of these two numbers are equal.
When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. In a proportional connection, one variable is always a constant value multiplied by the other, which is another way to think of them. The "constant of proportionality" is the term used to describe that constant. Two angles are said to be complimentary if their sum is 90 degrees. Alternatively put, two angles are said to be complimentary if they combine to make a right angle.

You are given the following information about N, the annual number of claims for a randomly selected insured:
P(N=0) = 1/2
P(N=1) = 1/3
P(N>1) = 1/6
Let S denote the total annual claim amount for an insured. When N=1, S is exponentially distributed with mean 5. When N>1, S is exponentially distributed with mean 8. Determine P(4
When N=1, P(S=4) = 1 - exp^(-4/5). When N>1, P(S=4) = 1 - exp^(-4/8). Therefore, P(S=4) = 1/2 * (1 - exp^(-4/5)) + 1/6 * (1 - exp^(-4/8)). S denote the total amount for an insured.
When N=1, the total annual claim amount for an insured, S, is exponentially distributed with mean 5. This means that the probability of S being equal to 4 is 1 - exp^(-4/5). When N>1, the probability of S being equal to 4 is 1 - exp^(-4/8). Since P(N=0) = 1/2 and P(N=1) = 1/3, the total probability of S being equal to 4 is the sum of the probabilities for N=1 and N>1. This is equal to 1/2 * (1 - exp^(-4/5)) + 1/6 * (1 - exp^(-4/8)).

A Boolean data type is a type of data that can have one of two possible values, either true or false.
Boolean values are used in logic and programming to make decisions and determine the flow of a program. In programming, Boolean values are typically represented with 0 for false and 1 for true. Examples of Boolean values include the following:
• (5 > 4) True
• (10 = 10) True
• (3 < 2) False
• (17 ≥ 17) True
• (“dog” = “cat”) False
• (“hello” ≠ “goodbye”) True
Boolean values are used in programming to perform calculations, make decisions, and control the flow of a program. For example, an if statement is a type of decision making statement that uses a Boolean expression to determine if a certain condition is true or false. If the condition is true, the program will execute the specified code, and if false, the program will skip the specified code. Boolean values are also used to perform calculations, such as in the AND, OR, and NOT logical operators, which are used to combine two or more conditions into one expression. For example, the AND operator would return true if both of the conditions are true and false if either of the conditions are false.

Square ABCD and equilateral triangle AED are coplanar and share AD, as shown. what is the measure, in degrees, of angle BAE?
The measure of angle BAE is equal to the sum of the measures of angles ABC and ACD, or 120°.
Since ABCD and AED are both plane figures and share AD, the measure of angle BAE must be equal to the measure of angle BCD. Angle BCD is the exterior angle of triangle ABC, so the measure of angle BCD is equal to the sum of the measures of angles ABC and ACD. Therefore, the measure of angle BAE can be calculated using the formula:
m∠BAE=m∠ABC+m∠ACD
Since triangle AED is equilateral, all three angles are equal to 60°. Therefore, the measure of angles ABC and ACD are both equal to 60°. Therefore, the measure of angle BAE is equal to the sum of the measures of angles ABC and ACD, or 120°.
