while on a walk in the country, you pass a field full of horses and geese. after a quick count, you determine there are 33 heads and 102 feet in the field. how many of each animal are there?
The field is full of 18 horses and 15 geese.
Let's assume that there are x horses and y geese in the field. The number of heads can be represented as x + y = 33. The number of feet can be represented as 4x + 2y = 102.
We can use substitution to solve for one variable in terms of the other. From the first equation, we can solve for y in terms of x:
y = 33 - x
Substituting this expression for y into the second equation, we get:
4x + 2(33 - x) = 102
Expanding and simplifying the expression, we get:
4x + 66 - 2x = 102
Solving for x, we get:
2x = 36
And x = 18
So there are 18 horses in the field. Substituting this value for x into the expression for y, we get:
y = 33 - x = 33 - 18 = 15
So there are 15 geese in the field. Thus, the field is full of 18 horses and 15 geese.

A ball is thrown from the top of a building with an initial velocity of 10 m/s and a height of 100 m. The ball makes an angle of 30 degrees with the horizontal and reaches a maximum height of 80 m. Calculate the potential energy of the ball at its highest point.
Step-by-step explanation:
To calculate the potential energy of the ball at its highest point, we first need to find the gravitational potential energy of the ball. Gravitational potential energy is given by the equation:
PE = mgh
where m is the mass of the ball, g is the acceleration due to gravity (9.8 m/s^2 on the surface of the earth), and h is the height of the ball above the ground.
At its highest point, the height of the ball is 80 m, so the gravitational potential energy can be calculated as:
PE = m * g * h = m * 9.8 * 80
where m is the mass of the ball.
Since the ball was thrown at an angle of 30 degrees with the horizontal, its initial velocity can be broken down into horizontal and vertical components:
v0x = v0 * cos(30) = 10 * cos(30) = 10 * sqrt(3)/2 m/s
v0y = v0 * sin(30) = 10 * sin(30) = 10/2 m/s
The potential energy of the ball at its highest point can be found by adding the initial kinetic energy of the ball to its gravitational potential energy. The kinetic energy of the ball can be calculated as:
KE = 1/2 * m * v0y^2
where m is the mass of the ball and v0y is the vertical component of its initial velocity.
The total potential energy of the ball at its highest point is given by:
PE = KE + mgh = 1/2 * m * v0y^2 + m * g * h
Substituting in the given values, we find:
PE = 1/2 * m * (10/2)^2 + m * 9.8 * 80
Note: The mass of the ball (m) is not given, so the answer is given in terms of m.
Answer:
Step-by-step explanation:
PE = 1/2 * m * (10/2)^2 + m * 9.8 * 80

To verify if the representation is a function for this problem, we should verify if each input is mapped to a single output. If there is an input that is mapped to more than one output, then the relation is not a function.
When does a relation represents a function?A relation represents a function when each input value is mapped to a single output value.
On a graph, a function is represented if the graph contains no vertical aligned points, that is, if there are no values of x at which we could trace a vertical line that would cross the graph of the function more than once.
With arrows, only one arrow can depart from each value of x, or more than one arrow departing from the same value of x but necessarily arriving at the same value of y.

In a bag of 10 marbles, there are 4 blue, 3 red, 2 green, and 1 yellow. What is the probability that you draw one marble that is blue, replace it, and draw another marble that is green? Enter your answer as a fraction in lowest terms. Do not add spaces to your answer. (EX: 1/2)
Work Shown:
A = the 1st marble is blue
B = the 2nd marble is green
Replacement is applied. This makes A and B independent.
P(A) = (4 blue)/(10 total) = 4/10 = 2/5
P(B) = (2 green)/(10 total) = 2/10 = 1/5
P(A and B) = P(A)*P(B) ... see note below
P(A and B) = (2/5)*(1/5)
P(A and B) = 2/25
Note: The equation is valid because events A and B are independent.

5x = 20
x = 4
More formally, if we subtract the first equation from the second, we get ...
(5x +2y) -(5x -3y) = (20) -(20)

A group of students was asked about the number of flights they have taken. The data is shown in the line plot. Which of the following best describes the spread of the data? Explain its meaning in this situation. The data has a range of 5, which is a wide spread. This means the greatest number of flights was 5. The data has a range of 15, which is a narrow spread. This means that there is not a large difference in the number of flights taken by the students. The data has a range of 5, which is a narrow spread. This means that most of the students have taken a similar number of flights. The data has a range of 15, which is a wide spread. This means that there is a difference of 15 flights between each of the students.
Answer:
In the case presented, the range is the difference between the maximum value and the minimum value of the data. The range describes the breadth of the data and how much they vary from the minimum value to the maximum value. Therefore, the range indicates the dispersion of the data.
The statement indicates that the range is 5, which means that the most flights made by students is 5. Since the data has a narrow dispersion, we can conclude that most students have taken a similar number of flights, implying that most students have flown an amount close to the maximum number observed.
Therefore, the option that best describes the dispersion of the data is: "The data has a range of 5, which is a narrow dispersion. This means that most students have taken a similar number of flights."

Find 2 numbers whose product is 57, and one of the numbers is 5 less than eight times the other number
One of the numbers is 21, and the other number is 2.5
What is an algebraic expression?
An algebraic expression is when we combine numbers and words to solve a mathematical problem.
Let's call one of the numbers "x". We know that x is 8 times greater than the other number, which we'll call "y". So we have:
y = x / 8
The product of x and y is 57, so:
x * y = 57
Substituting y = x / 8 into the equation above:
x * (x / 8) = 57
Expanding the right side of the equation:
[tex]x^2 / 8 = 57[/tex]
Multiplying both sides by 8:
[tex]x^2 = 8 * 57[/tex]
Solving for [tex]x^2[/tex]:
[tex]x^2 = 456[/tex]
Taking the square root of both sides:
[tex]x =\sqrt{456}[/tex]
x = 21
So, One of the numbers is 21, and the other number is 21 / 8 = 2.5.

Find the roots of the function f(x)=x^2+15x-16
Answer:
x = -16 and x = 1
Step-by-step explanation:
"Finding the roots" means solving the equation. We'll set the equation equal to 0 (replace f(x) with zero) and factor.
0 = x^2 + 15x - 16
0 = (x + 16)(x - 1)
This is factored.
Using the Zero Product Property, we separate this into two small equations.
x+16 = 0 and x-1 = 0
Solve these one-step equations.
x = -16 and x = 1
These are the roots (and roots are solutions, are zeros, are x-intercepts) If the question ask for zeros, roots, solutions or x-intercepts, set it equal to 0, factor and solve.
In a survey of 500 tourists, 350 like Pokhara, 200 like Chitwan and number of tourist who like both is half of who like Chitwan and 20 like neither of two, using Venn-diagram find how many like only one place.
Answer:
160 tourists like only one place. This can be determined by using a Venn diagram. Of the 500 tourists surveyed, 350 like Pokhara, 200 like Chitwan, and 50 like both places. That leaves 20 who like neither of the two places. To get the number of tourists that like only one place, subtract the number of tourists who like both (50) and the number of tourists who like neither (20) from the total number of tourists surveyed (500), resulting in a total of 160 tourists who like only one place.

The height of the cone is 24 centimetres.
How to find the height of the cone?A cone has a volume of 392π cubic centimetres and a radius of 7 centimetres. Therefore, the height of the cone can be found as follows;
Hence,
volume of a cone = 1 / 3 πr²h
where
h -= height of the coner = radius of the coneTherefore,
volume = 392π
r = 7 cm
392π = 1 / 3 × π × 7² × h
392π = 49 / 3 πh

I have $10,000 to invest for my daughter's car. I earned $215.04 when splitting the money into a
3% interest account and a 1.1% interest account. How much did I invest at each? (1 = prt; 1= interest
earned, p = principle (the amount invested), r = rate as a decimal, t = time in years)
The amount invested in the 3% interest account is $11,342.11, and the amount invested in the 1.1% interest account is $10,000 - $11,342.11 = $-342.11.
What is the interest?
Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
Let's call the amount invested in the 3% interest account x. Then, the amount invested in the 1.1% interest account is $10,000 - x.
The interest earned in the 3% interest account is 0.03x, and the interest earned in the 1.1% interest account is 0.011($10,000 - x).
The total interest earned is equal to the sum of the interest earned in each account:
0.03x + 0.011($10,000 - x) = $215.04
Expanding and solving for x:
0.03x + 0.011 * $10,000 - 0.011x = $215.04
0.019x = $215.04 + 0.011 * $10,000 - 0.011 * $10,000
0.019x = $215.04
x = $215.04 / 0.019
x = $11,342.11
Hence, the amount invested in the 3% interest account is $11,342.11, and the amount invested in the 1.1% interest account is $10,000 - $11,342.11 = $-342.11.
