Question Help A tourist asked a zookeeper how many birds and lions are in the zoo. The zookeeper replied there are 32 heads and 102 feet. Find the number of each.
Final answer:
By setting up and solving a system of equations, we find that there are 13 birds and 19 lions in the zoo.
Explanation:
To solve the problem of determining the number of birds and lions in the zoo given 32 heads and 102 feet, we can set up a system of equations. Birds have 2 feet, and lions have 4 feet. Let B represent the number of birds and L represent the number of lions.
Equations:
B + L = 32 (total heads)
2B + 4L = 102 (total feet)
Solving this system, we'll first multiply the first equation by 2 to facilitate elimination:
2B + 2L = 64
2B + 4L = 102
Subtracting the first modified equation from the second equation gives us 2L = 38, so L=19. Substituting L=19 into the first equation, we find B = 32 - 19 = 13.
Therefore, there are 13 birds and 19 lions in the zoo.

The boat average velocity for the one hour trip is 54° north of east.
What is Average velocity?
Average velocity is defined as the change in position divided by the time interval in which the displacement occurs.
Given that;
A small boat travel 32 km north and then travels 45 km east.
Now,
Average velocity is calculated as;
By figure,
Average velocity = cotθ = 32/45
θ = cot⁻¹ (32/45)
θ = 54°
Thus, The boat average velocity for the one hour trip is 54° north of east.

Ramon correctly answered 80% of the questions on his math test. Which of the following does NOT represent the part of the questions Ramon answered correctly?
The concept of percentages indicates that if Ramon answered 80% of the questions correctly in a test, it means he correctly answered a higher proportion of questions than the statement '30% of the students answered 16 or more questions correctly' would imply. Therefore, this statement does not represent the part of a test that Ramon answered correctly.
Explanation:This question concerns the concept of percentages in mathematics. The information provided indicates that Ramon correctly answered 80% of the questions on his math test. This implies that if the test had 100 questions, Ramon correctly answered 80 questions. Now let's consider the statement in the choices: '30% of the students answered 16 or more questions correctly.' This is in stark contrast to Ramon's result and therefore does not represent the part of the test questions that Ramon answered correctly. The 30% statement is considering the entire class's performance, not Ramon's individual accomplishment. Hence, the aforementioned statement is the one that doesn't represent the part of the questions Ramon answered correctly.

The selling price for a classic car is $16000 which is. $1000 more than three times its original price. What was the original price of the car?
The original price of the classic car was $5,000
The student's question seeks to determine the original price of a classic car, given that the selling price is $16,000, which is $1,000 more than three times its original price. To find the original price, we can set up an equation: let the original price be represented by x. The equation based on the information provided would be:
3x + $1000 = $16000
Subtracting $1000 from both sides to isolate the terms with x gives us:
3x = $16000 - $1000
3x = $15000
Finally, dividing both sides by 3 to solve for x, we get:
x = $15000 / 3
x = $5000
Therefore, the original price of the car was $5000.
The original price of the car was $5000
Let the original price of the car be x.
According to the problem, the relationship between the original price and the selling price can be described by the following equation:
[tex]\[ 3x + 1000 = 16000 \][/tex]
To find x :
Isolate x on one side :
Subtract 1000 from both sides to remove the extra cost:
[tex]\[ 3x = 16000 - 1000 = 15000 \][/tex]
Solve for x :
Divide both sides by 3:
[tex]\[ x = \frac{15000}{3} = 5000[/tex]
Thus, the original price of the car was $5000.
Question :
The selling price for a classic car is $16000 which is. $1000 more than three times its original price. What was the original price of the car?

What is the justification for each step in the solution of the equation?
23x−13=2(x+2)23x−13=2(x+2)
Select from the drop-down menus to correctly justify each step.
The solution involves the application of mathematical properties such as the distributive property, the process of simplifying, the use of additive inverse, and the division property of equality. These steps result in x = 0.81.
Explanation:To solve the given equation, 23x - 13 = 2(x + 2), let's break down the steps:
First, distribute 2 to each term within the parenthesis on the right side of the equation to apply the distributive property. This leads to 23x - 13 = 2x + 4. Second, gather like terms on both sides of the equation in a process known as simplifying the equation. Subtract 2x from both sides to get: 21x - 13 = 4. Next, you should isolate the variable x, by adding 13 to both sides of the equation. This use of additive inverse results in 21x = 17. Finally, divide each side of the equation by 21 to get x by itself—a step justified by the division property of equality. This results in x = 17/21, which simplifies to x = 0.81 (approximately).

We want to create a class that represents a geometric sequence. a geometric sequence is a sequence of numbers that begin at some value and then multiplies each value by some constant to get the next value. for example, the geometric sequence 1, 2, 4, 8, 16 starts at 1 and multiplies each term by 2 to get the next. the geometric sequence 10.8, 5.4, 2.7, 1.35 starts at 10.8 and multiplies each term by 0.5 to get the next. the basic framework of a geometric sequence class is below:
A geometric sequence class in programming can represent a series of numbers where each term is generated by multiplying the previous term by a fixed number. This follows the rules of exponential arithmetic, as seen in examples of exponential increase and decrease.
Explanation:In the context of programming, the basic framework of a geometric sequence class can represent a geometric sequence, following the rules of exponential arithmetic. In mathematics, a geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.
For instance, a geometric sequence that begins at 1 and multiplies each term by 2 would look as follows: 1, 2, 4, 8, 16. Notice that each subsequent term is twice the value of its previous term i.e., an exponential increase.
Similarly, the geometric sequence 10.8, 5.4, 2.7, 1.35 starts at 10.8 and multiplies each term by 0.5, resulting in an exponential decrease. While not directly related to the question, geometric sequences can also be used to calculate geometric probabilities.
