In a fish tank, the number of orange fish is 1 1/4 times the number of blue fish. Drag blue fish to represent the number of blue fish in the tank for every 5 orange fish
Final answer:
For every 5 orange fish in the fish tank, there are 4 blue fish since the number of orange fish is 1 1/4 times the number of blue fish.
Explanation:
In the fish tank scenario where the number of orange fish is 1 1/4 times the number of blue fish, for every 5 orange fish, we need to determine the corresponding number of blue fish. To find this, we can set up a ratio where the number of blue fish (let's call it B) multiplied by 1 1/4 must equal 5 (since 1 1/4 times B is the number of orange fish). So, B * 1 1/4 = 5. This equation can be simplified to B * 5/4 = 5, and by further simplification, we find B = 5 / (5/4) which is equal to B = 4. Therefore, for every 5 orange fish, there would be 4 blue fish in the tank. Hence, if you drag blue fish to represent the number of blue fish, there should be 4 of them for every 5 orange fish.

find the length of AB. leave your answer in terms of pi. Please please help!!!!
Answer:
3 pi
Step-by-step explanation:
The length of the arc AB is equal to the circumference times the fraction of the circle
AB = 2*pi*r * (degrees/360)
AB = 2 * pi* (27) * (20/360)
= 54 * pi * (1/18)
= 3 pi
We are asked to leave the answer in terms of pi
Actually, the answer should be 1/9 π. To convert from degrees to radians, you use the conversion π/180°. This is what you do: 20°/1 times π/180°. This let's you cancel out the degrees so you are left in terms of pi. That gets you 20π/180 which simplifies to 1/9 π or 0.11π if you need it as a rounded decimal.
One fifth of a number is subtracted from four fifth of the same number. If the result is 9, what is the number.
Let x be the unknown number. One fifth of this number is x/5, one fourth of this number is x/4. So, we have
[tex]\dfrac{x}{4}-\dfrac{x}{5} = \dfrac{5x-4x}{20} = \dfrac{x}{20}[/tex]
We know that this difference equals 9, so we have
[tex]\dfrac{x}{20}=9[/tex]
Multiply both sides by 20 to get
[tex]x=180[/tex]
Rewrite the formula for area of a circle to find the radius of a circle.
The area of a circle (A) is given by the formula where r is the circle's radius. The formula to find r is . If and , r is centimeters.
The formula to find the radius of a circle, given the area, is r = √(A/π). This comes from rearranging the formula for the area of a circle, A = πr², to solve for r.
Explanation:The area of a circle (A) is traditionally calculated with the formula A = πr², where A represents the circle's area, and r represents the circle's radius. If we want to rewrite this formula to solve for the circle's radius (r), we would divide both sides of the equation by π and then take the square root. This gives us the formula r = √(A/π). So, if we know the area of the circle and want to find out its radius, we can use this formula.

8x+5=bx-7 In the equation shown above, b is a constant. For what value of b does the equation have no solutions?
A: -8
B: -7
C: 5
D: 8
Answer:
D: 8
Step-by-step explanation:
8x+5=bx-7
Subtract bx from each side
8x-bx+5=bx-bx-7
8x-bx +5 = 7
Subtract 5 from each side
8x-bx +5-5 = 7-5
8x-bx =2
Factor out the x
(8-b)x =2
When 8-b =0 we have
0=2 which means we have no solutions since this is never true
8-b=0
Add b to each side
8-b+b=0+b
8=b
Final answer:
For the equation 8x + 5 = bx - 7 to have no solution, the value of b must be d. 8, which results in parallel lines if graphed and signifies an inconsistent equation.
Explanation:
The student has presented the equation 8x + 5 = bx - 7. To find for what value of b the equation has no solutions, we need to compare the coefficients on both sides of the equation because the variables must match for the equation to have a solution. When the coefficients of 'x' are equal, but the constants are different, the equation has no solution. In other words, the equation will be inconsistent, resulting in parallel lines if graphed.
Likewise, if b equals 8, the equation becomes 8x + 5 = 8x - 7. Subtracting 8x from both sides results in an equation 5 = -7, which is a contradiction and hence the equation has no solution. This means the correct answer is Choice D: 8.

What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, If they don't gain at least ten yards, the other team gets the ball.
Therefore, the sequences of four plays that result in the team getting to keep the ball should be more than 10 yards when we take the sum of the sequences.
So, 8 - 3 + 4 + 21 = 30 yards.
30 - 7 - 8 - 12 = 3 yards.
2 + 16 - 5 - 3 = 10 yards.

7x=3y+45
4x+5y=19 what’s the answer and show work
Answer:
x = 6, y = -1.
Step-by-step explanation:
7x = 3y + 45
4x + 5y = 19.... (1)
Rearranging the first equation:
7x - 3y = 45-----(2)
Multiply equation (1) by 3 and equation (2) by 5:
12x + 15y = 57
35x - 15y = 225
Adding :
47x + 0 = 282
x = 282 / 47 = 6.
To find the value of y substitute x = 6 into equation (2):
7(6) -3y = 45
-3y = 45 - 42 = 3
y = 3/-3 = -1.
Answer:
x = 6 and y = -1
Step-by-step explanation:
It is given two equations,
7x = 3y + 45
⇒ 7x - 3y = 45 -------(1)
4x + 5y=19
⇒ 4x + 5y = 19 --------(2)
To solve these equations
eq (1) * 4 ⇒ 28x - 12y =180 ----(3)
eq (2) * 7 ⇒ 28x + 35y = 133 ----(4)
eq(3) - eq(4) ⇒ 0x - 47y = 47
y = -47/47 = -1
eq(1) ⇒ = 7x - 3*-1 = 45
7x + 3 = 45
7x = 45 - 3 = 42
x = 42/7 = 6
Therefore x = 6 and y = -1

The third term in a sequence is 11.
The term-to-term rule is “take away 4”.
Write an expression, in terms of n, for the nth term of the sequence
The nth term of the sequence can be expressed as:
[tex]T_n = -4n + 23[/tex]
Given that:The term to term rule is "take away 4"The third term of a sequence = 11Calculations of first term and of nth term:Since term to term rule is to take away 4, thus when we go back in sequence, the rule will be to add 4 term to term.
Thus:
Second term = 4 + third term = 4 + 11 = 15
First term = 4 + second term = 15 + 4 = 19
Since the given sequence has a constant difference of -4 between each adjacent terms, thus it is an arithmetic progression with d = -4
The nth term of an arithmetic progression with difference d is given by:
[tex]T_n = T_1 + (n-1) \times d[/tex]
Since d = -4 and first term is 19, thus we have:
[tex]T_n = 19 + (n-1) \times (-4) = -4n + 23\\T_n = -4n + 23[/tex]
Thus, the nth term of the sequence can be expressed as:

The expression for the nth term of the given sequence is 23 - 4n. Starting from the third term which is 11, we find the first term and use the common difference to write the formula.
Explanation:The student is dealing with a linear sequence and is asked to write an expression for the nth term of the sequence based on the term-to-term rule 'take away 4'. To find the nth term of this arithmetic sequence, we need to use the structure of arithmetic sequences, which follow the pattern a_n = a_1 + (n - 1)d, where a_n is the nth term, a_1 is the first term, n is the term number, and d is the common difference between terms. Because we know that the third term is 11, we can backtrack to find the first term by adding 4 twice (since we have been taking 4 away to move forward in the sequence). Therefore, the first term a_1 is 11 + 4 + 4 = 19. Given the common difference is -4 (since we are taking away 4 each time), our nth term expression is a_n = 19 + (n - 1)(-4) or simplified a_n = 23 - 4n.

Choose an equation that when paired with the equation below, will create a system of equations with infinitely many solutions, one solution, or no solutions.
Answer:
Infinitely many solutions: [tex]-5x+9y=2[/tex]
One solution: [tex]-10x+5y=4[/tex]
No solution: [tex]-10x+18y=5[/tex]
Step-by-step explanation:
Solve for y from each equation to obtain the equation of the line in slope-intercept form:
[tex]y=mx+b[/tex]
m: slope
b: y-intercept
EQUATION ON THE TOP:
[tex]-10x+18y=4\\\\y=\frac{5}{9}x+\frac{2}{9}[/tex]
Equation 1:
[tex]5y=10x+4\\\\y=2x+\frac{4}{5}[/tex]
The equation on top and the equation equation 1 has different slopes and different y-intercept, therefore the system will have one solution.
Equation 2:
[tex]9y=5x+2\\\\y=\frac{5}{9}x+\frac{2}{9}[/tex]
The equation on top and the equation equation 2 are the same, therefore, the system will have infinitely many solutions.
Equation 3:
[tex]18y=10x+5\\\\y=\frac{5}{9}x+\frac{5}{18}[/tex]
The slopes are equal, then both lines will be parallels, therefpre the system will have no solution.
To form a system with infinite, one or no solutions, a second equation is chosen to be identical or a multiple, have different coefficients, or the same slope but different constants relative to the first equation, respectively.
Explanation:To address the student's question about creating a system of equations with either infinitely many solutions, one solution, or no solutions, it is important to understand the properties of linear equations. When two equations are combined to form a system, the number of solutions is determined by their graphs on a coordinate plane. Three scenarios are possible:
Infinitely many solutions: This occurs when the two equations represent the same line; thus, they are identical or multiples of each other.One solution: This happens when the two lines intersect at a single point, meaning that they are not parallel and have different slopes.No solutions: This is the case when the two lines are parallel but not coincident, having the same slope but different y-intercepts.To create a system with a known outcome, one must write a second equation with either the same coefficients and constant term (for infinitely many solutions), different coefficients (for one solution), or the same coefficients but a different constant term (for no solutions).
For example, if the given equation is y = 2x + 3, an equation for infinitely many solutions could be 2y = 4x + 6, for one solution y = -x + 1, and for no solutions y = 2x + 5.
