Answer: in 12 years (2017)
23,000 students enrolled
Step-by-step explanation:
Let x represent the number of years since 2005.
Let y represent the number of students enrolled.
College A: y = 14,000 + 750x
College B: y = 35,000 - 1000x
Solve the system using the Substitution Method:
14,000 + 750x = 35,000 - 1000x
+1000x +1000x
14,000 + 1750x = 35,000
-14,000 -14,000
1750x = 21,000
x = 12
Input x = 12 into one of the equations to solve for y.
y = 35,000 - 1000x
= 35,000 - 1000(12)
= 35,000 - 12,000
= 23,000
Explanation on when two colleges will have the same enrollment and what the enrollment will be at that time.
Explanation:Step 1: Set up equations for the enrollment at each college over time. Let x be the number of years since 2005:
College A enrollment = 14000 + 750x
College B enrollment = 35000 - 1000x
Step 2: Set the two equations equal to each other:
14000 + 750x = 35000 - 1000x
Step 3: Solve for x to find when the colleges will have the same enrollment:
x = 10 years
Step 4: Substitute x back into the equations to find the enrollment at each college after 10 years:
College A enrollment = 14000 + 750(10) = 21500 students
College B enrollment = 35000 - 1000(10) = 25000 students
A college football stadium holds 45,000 fans. In a random sample of 30 fans, 25 were wearing the colors of the home team. Predict the number of fans who are wearing the colors of the home team.
Answer:
A
Step-by-step explanation:
Remark
Just as a guess, the answer should be A or B. It's always a good idea to estimate an answer so that if you get something really far away, you know it is incorrect.
Equation
Set up a proportion for the problem
26/30 is the basic ratio of the home fans wearing the right color
x/45000 is the ratio of those in the entire stadium.
Solution
26/30 = x / 45000 Cross multiply
30x = 26 * 45000 Simplify the right
30x = 1170000 Divide by 30
30x/30 = 1170000/30
x = 39000 And that is A

PLEASE HELP. Prove that the value of the expression: b (36^5−6^9)(38^9−38^8) is divisible by 30 and 37.
By factoring out and simplifying, we can see that given expression is divisible by both 30 and 37.
Explanation:The method for solving this question involves using certain properties of numbers and exponents. Firstly, observe the expressions (36^5-6^9) and (38^9-38^8). You can factor out 6^5 from the first expression and 38^8 from the second expression, giving you 6^5(6^4-1) and 38^8(38-1) respectively.
You will notice that 6^4-1 is 1295 and 38-1 is 37. Both 1295 and 37 are divisible by 37, rendering the whole expression divisible by 37. Moreover, 1295 is divisible by 5 and 6^1 is divisible by 6, making the expression divisible by 5*6 = 30.
Therefore, the whole expression is divisible by both 30 and 37.

To prove the divisibility of the expression, we factor and simplify it. The expression is divisible by both 30 and 37 due to its factors.
Explanation:To prove that the value of the expression b(36^5 - 6^9)(38^9 - 38^8) is divisible by 30 and 37, we can factor out 6 from both terms in each parenthesis.
This gives us b(6^4)(6^9 - 1)(38^8)(38 - 1).
Next, we divide each term by 6, giving us b(6^3)(6^9 - 1)(38^8)(38 - 1)/6.
We can simplify this expression further by factoring out 2 from both terms in the first parentheses, giving us 2^3b(6^6)(6^3 - 1)(38^8)(38 - 1)/6.
Now we can see that the expression is divisible by both 30 and 37, since it contains factors of 2, 3, 5, and 37.

the length and width of a rectangle are consecutive even integers. the area of the rectangle is 120 square units. what are the length and width of the rectangle
The length and width of the rectangle is 12 and 10 respectively.
Let the consecutive integers be :
a ; a+2Area of rectangle = Length × width
120 = a(a + 2)
120 = a² + 2a
a² + 2a - 120 = 0
a² - 10a + 12a + 120 = 0
a(a - 10) + 12(a - 10)
a = 10 or a = -12
The width cannot be negative, Hence, width = 10
Length = a + 2
Length = 10 + 2
Length = 12
The length and width of the rectangle is 12 and 10 respectively.

What are the values of s,v,w,x,y,z?
Answer: s, v, w, & x = 13 y = 20 z = 20 + 13√3
Step-by-step explanation:
First, you need to understand the side lengths of each special triangle in the drawing.
A 45°- 45°- 90° triangle has corresponding sides of a - a - a√2
A 30°- 60°- 90° triangle has corresponding sides of b - b√3 - 2b
The hypotenuse of the 45-45-90 triangle is 13√2, so its legs are 13.
So A F = 13 → s = 13 and w = 13
FB = 13 → x = 13
EC = 13 → v = 13
Since the x-value of C is 20, then the x-value of E is also 20 → y = 20
ED is opposite of the 60° angle of the 30-60-90 triangle so ED is EC√3. Since EC = 13, then ED = 13√3.
AE + ED = AD
20 + 13√3 = AD → z = 20 + 13√3

When developing a plan for a proof, it is important to look at the "given" information. True False
Answer:
Yeah true
Step-by-step explanation:
Because it makes sense
It is true that when developing a proof, focusing on the "given" information is crucial as it forms the foundation of the logical argument leading to the conclusion that needs to be proven.
When developing a plan for a proof, it is indeed important to look at the "given" information. This is true because in the context of mathematical proofs, the "given" information represents the starting point from which you will build you argument to reach a conclusion. These are the facts, definitions, or previously proven theorems that can be used in establishing the validity of the statement you are tasked to prove.
To develop a successful proof, one generally follows a systematic approach:
Identify the given information in the problem.Analyze what the problem is asking you to find or prove.Consider what principles, theorems, or rules apply based on the given information.Develop a logical sequence of steps that connects the given information to the conclusion you are trying to reach.This structured approach to problem-solving involves using what you know to logically arrive at a conclusion that was previously unknown or needs to be proven. This method not only applies to mathematics but also to other fields that require logical reasoning and evidence-based conclusions.

In a certain class of students, there are 12 boys from wilmette, 5 girls from kenilworth, 7 girls from wilmette, 4 boys from Glencoe, 2 boys from kenilworth and 9 girls from Glencoe. If the teacher calls upon a student to answer a question, what is the probability that the student will be from kenilworth?
Answer:
7/39 = 17.94%
Step-by-step explanation:
Town Students Relative Frequency
Wilmette 12 boys + 7 girls = 19 19/39 = 48.72%
Glencoe 9 girls + 4 boys = 13 13/39 = 33.33%
Kenilworth 2 boys + 5 girls = 7 7/39 = 17.94%
Total 39 students 39/39 = 100%
Another approach to solve probability is the Relative Frequency. A frequency is the number of times an event occurs. To solve for the relative frequency, it’s the ratio of the frequency of an event to the total outcomes. From the question, it is clear that for each town, it was subdivided into boys and girls but the word students represent the combined number of boys and girls for a particular town. so finding the probability that a student called at random to answer a question is from kenilworth is simply the ratio of students from kenilworth over the total number of students in the class.

which of the following is the solution to |10x|>-2
Let's reason through it.
We are given the inequality that says, in English, that the absolute value of ten times x is greater than -2.
Let's consider three cases:
x is negative
- When x is negative the number in the absolute value will be negative. But because it is inside the absolute value, the number becomes positive. Therefore, for any x that is negative (however small or large), the left side will be positive. Any positive value (however small) is greater than a negative value, so the inequality is satisfied in this case.
x is positive
- When x is positive, the number inside the absolute value will be positive. The absolute value of a positive number is itself, so the left hand side will be positive again. Then, for all positive values of x (however small or large), the inequality will be satisfied because any positive value is larger than -2.
x is zero
- Even in the case of zero, when the left hand side will be zero, the equality is satisfied. This is because zero is greater than -2. If this doesn't immediately make sense, imagine the two numbers on the number line. 0 is to the right of -2, so it is larger.
Since we cannot find a value for x that does not satisfy the inequality, the solution to the inequality is all values of x. See the attached image.
