there are 50 adult tickets and 100 student tickets sold
Step-by-step explanation:
Let x = number of adult tickets and y= number of student tickets
We have the following equation
x + y = 150 (1) =>total number of tickets
7x + 5y = 850 (2) > total cost of x adult and y student tickets
Multiply (1) x 5:
5x + 5y = 750 (3)
Subtract (2) - (3)
7x + 5y - (5x + 5y) = 850 - 750
7x - 5x + 5y - 5y = 100
2x = 100
x = 50
y = 150 - 50 = 100

A great-uncle has decided to give you a gift of $1,000. Being a financially savvy uncle, before giving you the money, he offers you a choice of the following: You can take the $1,000 today. You can wait five years and be given $1,200 instead 1. How will you decide if the offer presented by your great uncle is to your advantage? 2. Research interest rates for a savings account, checking account, and money market account at different financial institutions. Note the compounding period for each. How much would $1,000 be worth in each account in five years? 3. What are some factors that cause the value of money today to be different from its value in the future?
1. To decide if the offer presented by your great uncle is to your advantage, you need to consider the time value of money. This means that money available today is worth more than the same amount of money available in the future, due to the potential for earning interest or returns on the money. In this case, you need to compare the value of $1,000 today with the value of $1,200 in five years. If you can earn a rate of return greater than 4% over the next five years, it would be better to take the $1,000 today and invest it to earn a higher return. However, if you cannot earn a return greater than 4%, it would be better to wait and take the $1,200 in five years.
2. Interest rates and compounding periods will vary depending on the financial institution and type of account. As an example, let's assume that you are considering a savings account, checking account, and money market account with the following interest rates and compounding periods:
Savings account: 2% interest rate compounded annuallyChecking account: 0.1% interest rate compounded monthlyMoney market account: 2.5% interest rate compounded quarterlyUsing a compound interest calculator, the future value of $1,000 in each account after five years would be:
Savings account: $1,104.08Checking account: $1,005.02Money market account: $1,130.473. The value of money today can be different from its value in the future due to inflation, changes in interest rates, economic growth, and changes in the supply and demand for goods and services. Inflation is one of the biggest factors that can affect the value of money over time. If the rate of inflation is high, the value of money will decrease over time, meaning that the same amount of money will buy fewer goods and services in the future. On the other hand, if the rate of inflation is low, the value of money will increase over time, meaning that the same amount of money will buy more goods and services in the future. Interest rates can also affect the value of money, as higher interest rates can make it more attractive to save money, while lower interest rates can make it more attractive to borrow money. Economic growth and changes in the supply and demand for goods and services can also affect the value of money, as these factors can affect the overall price level of goods and services in the economy.

Does an ice cube with a lower volume melt faster or slower? This is for a math project
An ice cube with a lower volume will melt faster than an ice cube with a higher volume. This is because there is the less mass and surface area for the heat to transfer through, causing the ice cube to melt at a quicker rate.
For example, imagine two ice cubes, one with a volume of 2 cubic centimeters and another with a volume of 4 cubic centimeters. The ice cube with the lower volume (2 cubic centimeters) will melt faster than the ice cube with the higher volume (4 cubic centimeters) because there is less mass for the heat to transfer through. In conclusion, an ice cube with a lower volume will melt faster than an ice cube with a higher volume. This is due to the fact that there is the less mass and surface area for the heat to transfer through, causing the ice cube to melt at a quicker rate.

Which equation represents a line that is per
The equation which is perpendicular to the equation of line passing through the points (-4, 7) (1, 3):
y = 5/4x + 8.
What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
To find the equation of a line that is perpendicular to another line, we need to know the slope of the original line.
The slope of the line passing through (-4,7) and (1,3) is:
m = (3 - 7) / (1 - (-4)) = -4/5
The slope of any line perpendicular to this line would be the negative reciprocal of -4/5, which is 5/4.
Therefore, the equation of a line that is perpendicular to the line passing through (-4,7) and (1,3) would be of the form:
y = 5/4 x + b
where b is the y-intercept.
Among the given options, the equation that matches this form is:
A. y = 5/4 x + 8
So the answer is (A) y = 5/4x + 8.

What are the rational roots of the polynomial P(x) = x^3 + 3x^2 + x - 1
The rational roots of the polynomial P(x) = x^3 + 3x^2 + x - 1 can be found using the Rational Root Theorem.
The Rational Root Theorem states that if a polynomial has a rational root, it will be in the form of p/q, where p is a factor of the constant term and q is a factor of the leading coefficient. In this case, the constant term is -1 and the leading coefficient is 1. The factors of -1 are -1 and 1, and the factors of 1 are 1. Therefore, the possible rational roots of this polynomial are -1/1, 1/1, or -1 and 1.
We can test these possible roots by plugging them into the polynomial and seeing if the result is 0.
P(-1) = (-1)^3 + 3(-1)^2 + (-1) - 1 = -1 + 3 - 1 - 1 = 0
P(1) = (1)^3 + 3(1)^2 + (1) - 1 = 1 + 3 + 1 - 1 = 4
Therefore, the only rational root of this polynomial is -1.
So, the rational roots of the polynomial P(x) = x^3 + 3x^2 + x - 1 are -1.

Triangle ABC is similar to triangle FGH. Given the following angle measures, find the missing angle measures.
The measures of angles in similar triangles are ∠ F = 22°, ∠ G = 75° and ∠ H = 83°
What are similar triangles?Similar triangles have the same corresponding angle measures and proportional side lengths.
Given that, Triangle ABC is similar to triangle FGH, we need to find the measures of the angles,
The sum of interior angles of a triangle = 180°
Considering Δ ABC,
∠ A + ∠ B + ∠ C = 180°
∠ C = 180°-(22°+75°)
∠ C = 83°
Since, we know that the similar triangles have congruent corresponding angles,
Therefore,
∠ A = ∠ F, ∠ B = ∠ G and ∠ C = ∠ H
Therefore, the measures of angles in Δ FGH are ∠ F = 22°, ∠ G = 75° and ∠ H = 83°

The Perimeter of the pentagon ABCDE is 17 units.
What is Distance Formula?If two points in coordinates plane P(a, b) and Q(c, d) then the distance between these points are
PQ = √(c-a)² + (d-b)²
Given:
The coordinates of Pentagon are A (4, 3), B (7, 3), C (8, 0), and D (2, -3) and E(0, 1).
Using Distance formula
AB = √(7-4)² + (3-3)²
AB = √9
AB = 3
BC = √(8-7)² + (0-3)²
BC = √1 + 9
BC = √10
CD = √(2-8)² + (-3-0)²
CD = √36 + 9
CD = √45
CD = 3√5
DE = √(0-2)² + (-3-1)²
DE = √4 + 16
DE = √20
DE = 2√5
So, Perimeter of the pentagon ABCDE = AB+BC+CD+DE+EA

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
By figure,
The shape shows the rectangular prism.
We know that;

Height of prism = 1.7 in
Hence, We get;
The surface area of prism is,
⇒ S.A = 2B + ph
⇒ S.A = 2 × 50 + 100 × 1.7

Step-by-step explanation: Solve for side b using the Pythagorean therom since this is a right triangle.
[tex]a^2+b^2=c^2[/tex] - Where c is the largest side aka hypotenuse(if you are unsure, look at the side opposite to the right angle)
Substitute the given values to solve for the unknown side
[tex]9^2+b^2=15^2[/tex]
Expand
[tex]81+b^2=225[/tex]
Subtract 81 from both sides
[tex]b^2=144[/tex]
Which means
[tex]b=+-12[/tex]
but since its a triangle in the first quadrant and can only contain positive values, we disregard the negative solution. So b=12.
Lastly, for perimeter, just add all the side lengths together.
