The required ratio of 2 frogs to 5 turtles is given as 2 / 5 or 2:5.
As mentioned in the question ratio of the 2 frogs and 5 turtles is to be determined.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
The ratio of the two terms is given as a / b or a: b
Let a = number of frogs ad b = number of turtles,
Now, put the values of a and b in a/b or a:b
So,
The ratio is given as,
= 2/5 or 2:5
Thus, the required ratio of 2 frogs to 5 turtles is given as 2 / 5 or 2:5.

Mr. Delong's drama class is planning a field trip to see a Mozart's famous opera Don Giovanni. Tickets cost $39 each, and there are 23 students and 2 teachers going on the field trip. Write and evaluate an expression to find the groups total ticket cost.
The total ticket cost for Mr. Delong's drama class to attend Mozart's opera Don Giovanni, with 23 students and 2 teachers at $39 per ticket, is $975.
To calculate the total ticket cost for Mr. Delong's drama class field trip to see Mozart's opera Don Giovanni, we need to combine the number of students and teachers going to find out how many tickets in total need to be purchased. There are 23 students and 2 teachers, so that's a total of 25 people needing tickets. The cost per ticket is $39.
The expression to find the total ticket cost is (Number of Students + Number of Teachers) x Cost per Ticket, which translates to (23 + 2) x $39.
Doing the math: (25) x $39 = $975.
Therefore, the group's total ticket cost for attending the opera will be $975.

Which graph represents the solution set of the system of inequalities?
{y>−2x−2
y ≤ x+4
Answer:
Its the first gragh
Step-by-step explanation:
Graph D is a correct choice.
We have a set of inequalities -
y > − 2x − 2
y ≤ x + 4
We have select the graph that represents the solution set of the system of inequalities.
What is an Inequality in mathematics ?An inequality compares two values or expressions, showing if one is less than, greater than, or simply not equal to another value.
According to the question, we have -
y > − 2x − 2Let → y = -2x - 2
Now, plot the graph of the line → y = - 2x - 2 with a Dotted line ( > is a strict inequality).
Assume a point (0,0) -
0 > - 2 x 0 - 2
0 > -2
Which is true, hence shade the area where the point (0, 0) lies.
y ≤ x + 4Let → y = x + 4
Now, plot the graph of the line → y = x + 4 on the graph.
Assume a point (0,0) -
0 ≤ 0 + 4
0 ≤ 4
Which is true, hence shade the area where the point (0, 0) lies.
Refer to the image attached for final graph - the area under the Red thick line is common to both and is the solution set of system of inequalities.
Hence, Graph D is a correct choice.

Solve the equation with rational exponents (x-4)^2/3= 9
The solution to the given expression is x = 31.
In order to simplify an expression with exponents of the same base, we would have to apply the properties of multiplication of exponents with the same base;
[tex](k^m)\cdot(k^{n})=k^{m+n}[/tex]
Based on the properties of roots of exponents, we have the following:
[tex]\sqrt[a]{x^b} =x^{\frac{b}{a} }[/tex]
By raising both sides of the given expression to the reciprocal of the exponent, we have:
[tex](x-4)^{\frac{2}{3} }=9\\\\((x-4)^{\frac{2}{3} })^{\frac{3}{2} }=9^{\frac{3}{2} }\\\\x-4=(9^{\frac{1}{2} })^{3 }\\\\x-4=(3)^{3 }\\\\[/tex]

Of all numbers x and y whose sum is 50, the two that have the maximum product are xequals=25 and yequals=25. that is, if xplus+yequals=50, then xequals=25 and yequals=25 maximize qequals=xy. can there be a minimum product? why or why not?
x + y = 50
Q = x * y
Combining the two:
Q = x * (50 - x)
Q = 50x - x^2
Q = -x^2 + 50x
Q = -(x^2 - 50x)
Q = -(x^2 - 2 * 25x + 25^2 - 25^2)
Q = 25^2 - (x - 25)^2
Q = 625 - (x - 25)^2
So what we got is an equation for parabola with a vertex at
(25 , 625) and it opens downward. We know that parabolas only have one critical
value, so if x and y are unrestricted, then there's no minimum product.
No, there cannot be a minimum product. The product of two numbers is maximized when the numbers are equal or close to each other.
Explanation:The student is asking if there can be a minimum product when x and y are numbers whose sum is 50 and we are trying to maximize the product xy. The answer is no, there cannot be a minimum product. This is because the product of two numbers is maximized when the numbers are equal or close to each other. In this case, when x = 25 and y = 25, the product xy is maximized at 625. If x and y were further apart, the product would be smaller.
Thus,
Q = x * (50 - x)
Q = 50x - x^2
Q = -x^2 + 50x
Q = -(x^2 - 50x)
Q = -(x^2 - 2 * 25x + 25^2 - 25^2)
Q = 25^2 - (x - 25)^2
Q = 625 - (x - 25)^2
What is the value of the expression 4x+y2y−x when x = 2 and y = 4? a. 2 b. 3 c.4 d.6
By substituting the values x=2 and y=4 into the given equation, we get a result of 70 which does not match with any of the provided options.
Explanation:The value of the expression 4x + y-2y−x when x = 2 and y = 4 can be determined by substituting these values into the expression. By doing so, we get:
4 * 2 + 4^2 * 4 - 2 = 8 + 64 - 2 = 70
So, the correct value is 70, which is not present in the provided options (a. 2 b. 3 c.4 d.6). Maybe there is a misunderstanding or typo in the question or options. The way it's presented right now, the correct answer would be none of the above.

I need solve each system by substitution 4x+2y=7;y=5x
To solve the system of equations by substitution, substitute the value of y from the second equation into the first equation. The solution is x = 1/2 and y = 5/2 or 2.5.
Explanation:To solve the system of equations by substitution, we substitute the value of y from the second equation into the first equation.
Given that y = 5x, we can substitute this value into the first equation:
4x + 2(5x) = 7
Simplifying the equation:
4x + 10x = 7
Combine like terms:
14x = 7
Divide both sides by 14:
x = 7/14
Simplify:
x = 1/2
Now substitute this value of x back into the second equation to find y:
y = 5(1/2)
Simplify:
y = 5/2 or y = 2.5

What is the expression x - 4 represents a negative integer. What integers could X represent?
Answer:
Integers between (-∞, 4)
Step-by-step explanation:
Negative Integer is integers whose value is less than 0 i.e. -1, -2, -3, -4,.... so on.
The expression x - 4 will be negative if x is less than 4.
For Example, if we take integers greater than 4 or equal to 4 as the value of x then,
5 - 4 = +1 which is not a negative integer
4 - 4 = 0 which is again not a negative integer.
But, if we take x as less than 4 then we get,
2 - 4 = -2 i.e. negative integer
-3 - 4 = -7 i.e. also negative integer.
So, for all value of x which is less than 4, we will get a negative integer.
The scatter plot shows how many desks and computers were found in 12 diffirent offices. how many offices had fewer than 5 desks
Answer:
5 offices had fewer than 5 desks
Step-by-step explanation:
Clearly from the scatter plot we could see that 5 offices have lesser than 5 desks.
The number of desks are represented by the horizontal axis and the number of computers are represented by the vertical axis.
so by looking at the scatter plot we could see that the five points are before 5 on the horizontal axis i.e. we have to count all those points such that the desk are less than 5 i.e. ( when the desks are 0,1,2,3 and 4).

Use the interactive tool to graph the line given the following information: coordinates (1,–3) slope of –2 Based on your investigation, what is the value of b for the point (0,b)?
Finding the equation of the line, it is found that the value of b is -1.
----------------------------
The equation of a line is given by:
[tex]y = mx + b[/tex]
In which:
m is the slope.b is the y-intercept.----------------------------
Slope of -2 means that [tex]m = -2[/tex], and thus, [tex]y = -2x + b[/tex].It goes through point (1,-3), which means that when [tex]x = 1, y = -3[/tex]. We use this to find b.[tex]y = -2x + b[/tex]

The formula calculating the area of circle is
A = π[tex]r^{2}[/tex] where r is radius ( half of the diameter )
A = [tex](12)^{2}[/tex]
A = 452.38934 [tex]inches^{2}[/tex]
