Leroy won the raffle at the zoo and gets to feed the dolphins! The dolphin trainer gives Leroy
a bucket of fish to divide evenly among 5 dolphins. Each dolphin gets 4 fish.
Which equation can you use to find the number of fish f in the bucket before Leroy feeds the
dolphins?
F/5=4
5f=4
F-5=4
F+5=4
Answer:
A. F/5 = 4
Step-by-step explanation:
F is the total of fish so F is divided by the total of dolphins, which is 5
so F/5 = 4
Answer:
F/5=4
Step-by-step explanation:
F is the total amount of fish. Since there are 5 dolphins to feed, you should divide F by 5.
The profit from selling local ballet tickets depends on the ticket price.

C) Two prices between which a profit is made are $19 and $21.
What are quadratic functions?f(x) = ax² + bx + c, where a, b, and c are numbers and are not equal to zero, is a quadratic function.A parabola is the shape of a quadratic function's graph.The graph's vertex, which is an extreme point, is one of its key characteristics. The vertex, or lowest point on the graph or minimal value of the quadratic function, is where the parabola will open up. The vertex is the highest point on the graph or, if the parabola opens downward, the maximum value.Given:
profit function P(x)= -15x² + 600x + 60
The value of a is -15, which is negative, so the graph is opening downwards.
The graph of the function is a parabola and it opens downward therefore it has a maximum point. The formula used to find the vertex of the parabola f(x) is given by
x-coordinate of the vertex = -b/2a
y-coordinate of the vertex = f(-b/2a)
We have the x-coordinate of the parabola as:
⇒ -600 / 2(-15)
⇒ -600/-30 = 20
A) x, i.e. price of each ticket should be charged 20 dollars to maximize revenue.
B) y-coordinate of the vertex is given by
f(20) = -15(20)² + 600(20) + 60
= 6060
The maximum revenue is 6060 dollars.
C) f(21) = -15(21)² + 600(21) + 60
= 6045
f(19) = -15(19)² + 600(19) + 60
= 6045
at $21, the profit is $6045
at $19, the profit is $6045
Two prices between which a profit is made are $19 and $21.

The total number of fiction books are 2385.
What is constant of proportionality?
The constant of proportionality is the ratio of two proportional values at a constant value is known as the constant of proportionality. When either their ratio or product results in a constant, two variables' values are said to be proportionally related. The ratio between the two stated quantities determines the value of the proportionality constant.
Given that,
Let the total number of fiction books be f and nonfiction books be n.
The constant of proportionality between the number of fiction book(f) and the number of non-fiction books(n) in a library is 15/22 .
f/n= 15/22
Also, the total number of nonfiction books is 3498.
Therefore,
f/3498 = 15/22,
f= 15/22 x 3498,
f= 15 x 159,

Determine whether each infinite geometric series converges or diverges. If the series converges, state the sum. 2/3 + 4/9+8/27+ ......
The given infinite geometric series 2/3+4/9+8/27+ ...... is convergent and the sum is 2
The given geometric series is:
2/3 + 4/9 + 8/27 + ......
The common ratio (r) of a geometric series is given by:
r = a(n) / a(n - 1)
Notice that in the given series:
a(1) = 2/3
a(2) = 4/9
a(3) = 8/27
Hence, the common ratio is
r = a(2) / a(1) = (4/9) / (2/3) = 2/3
An infinite geometric series is convergent if 0 < | r | < 1.
Since r = 2/3, then the series is convergent and the sum exists.
Use the sum formula:
S = a(1) / (1 - r)
Substitute a(1) = 2/3 and r = 2/3 into the formula:
S = (2/3) / (1 - 2/3)
= (2/3) / (1/3)

Austin makes $10 an hour working as a cashier at a bookstore. His employer requires him to work at least 10 hours per week and his current school schedule limits him to a maximum of 25 hours per week.
1. Write an equation that represents Austin's gross pay where x represents the number of hours he works per week and f(x) (as in functions) represents his gross pay.
2. What is the domain and range in this situation?
The linear function is:
f(x) = $10*x
Where the domain is: [10, 25]
And the range is: [$100, $250]
How to write the equation that models Austin's gross pay?Here we know that x represents the number of hours that he works per week, and we also know that he wins $10 per hour, then if he works x hours, the amount that he wins is x times $10, so the equation is just:
f(x) = $10*x
Now we also want to get the domain and range for this function. We know that he needs to work at least 10 hours and at maximum of 25 hours, so we have the restrictions:
10 ≤ x ≤25
So the domain is D: [10, 25]
To find the range we evaluate in the values of the domain, the minimum of the range is f(10) = $10*10 = $100
The maximum of the range is f(25) = $10*25 = $250
Then the range is R: [$100, $250]

The figure includes two right angled triangles.
Consider the first right angled triangle:
Hypotenuse = 7 units
Base = 3 units
Altitude = a
By using Pythagorean theorem, we can find a.
That is,
Hypotenuse² = Altitude² + Base²
7² = a² + 3²
49 = a² + 9
a² = 49 - 9
a² = 40
Altitude = [tex]\sqrt{40}[/tex] units
Now consider second right angled triangle:
Hypotenuse = [tex]\sqrt{40}[/tex] units
Altitude = 4 units
Base = x units
Apply Pythagorean theorem:
Hypotenuse² = Altitude² + Base²

Circle J has a radius of 10 units, ®K has a radius of 8 units, and BC = 5.4 units. Find the measure.
AB
Circle J has a radius of 10 units and BC = 5.4 units then the measure of AB is 14.6 units.
What is meant by the radius of a circle?A radius of a circle or sphere is any of the line segments from its center to its perimeter in classical geometry, and in more modern usage, it is also their length. The name is derived from the Latin radius, which means both rays and spoke of a chariot wheel.
The radius of a circle is the distance between the circle's center and any point on its circumference. It is usually represented by the letters 'R' or 'r'. This number is significant in almost all circle-related formulas. A circle's area and circumference are also measured in terms of radius.
Since AC is the diameter of circle J and the radius is 10, AC = 2(10) or 20 units.
AB + BC = AC
Where the value of BC = 5.4, we get
substitute the value of BC in the above equation, then we get
AB + 5.4 = 20
subtract 5.4 from both sides
AB + 5.4 - 5.4 = 20 - 5.4
simplifying the above equation,
AB = 14.6
Therefore, the measure of AB is 14.6 units.

r = ratio
The given geometric sequence is:
3,12,48,192, . . .
Find the ratio
r = a(n)/a(n-1)
= a(2)/a(1) = 12/3 = 4
Use the formula for the nth term.
a(n) = a(1) . r^(n-1)
In the given sequence a(1) = 3.
Substitute a(1) = 3, r = 4, and n = 5:
a(5) = 3 . 4⁵⁻¹
= 3 . 4⁴ = 768
