Given information:
1.5 ft³ = Volume of water required per fish.Dimensions of the tank = 5 ft × 3 ft × 4 ftModel the tank as a rectangular prism.
[tex]\begin{aligned}\textsf{Volume of a rectangular prism}&=\sf width \times length \times height\\\\\implies \textsf{Volume of tank}&=\sf 5 \; ft \times 3\; ft \times 4 \; ft\\& = \sf 15\;ft^2 \times 4\;ft\\& = \sf 60 \; ft^3\end{aligned}[/tex]
To find the maximum number of fish that can be put in the tank, divide the found volume of the tank by the given volume of water required per fish:

The value of P = $5000, r = 3.6%/4 = 0.9%, n = 4n and amount after 10 years is $5450.
Compound interest may be defined as the interest which can be applied by any institution on any individual in which the interest amount after a year becomes principle for the next year. The formula for compound interest is given as A = P(1 + r/n) ^ nt where A is the amount, P is the principle, r is the interest rate, n is compounding frequency and t is the time. If compounded quarterly the principle will be same as in the question that is $5000, the interest rate will be divided by 4 that is r = 0.9% and the compounding frequency will be 4 times that is 4n. Now, we need to find the amount after 10 years that is t = 10 years. The amount will be
A = P(1 + r/4n) ^ 4nt
A = 5000(1 + 0.9/100×4×12) ^4×12×10
A = 5000(1.09)
A = $5450 which will be amount after 10 years.

The complex number factors are (x+5i) and (x-5i).
The term a + bi, where a and b are real numbers, can be used to represent any complex number.
A complex number is a component of a number system that includes an element with the symbol I, sometimes known as the imaginary unit, and that extends the real numbers by satisfying the equation i² = -1. Since no real number can fulfil the conditions in the previous equation, i was referred to as an imaginary number. The complex number a + bi is known as having real and imaginary parts, respectively, a and b. The group of complex numbers is represented by the letter C.The given expression is x² + 25
Now this can be written as :
x² - [(i)²×(5)²] as we know that i² = -1.
Now we use the algebraic form of a²-b² =(a + b)(a - b) to separate it into complex factors.

Rotating a figure causes it to twist. Even though the figure is the same size and shape as before, it appears to have toppled over. A clock is a fantastic example of how the earth actually rotates. Every hour or every day, the clock's connecting arms revolve around their axis. A rotation's degree determines what it is, and common rotations include 90, 180, and 270 degrees. Before going back to its original position, the figure rotates a full 360 degrees. the direction of a rotation, whether it is counterclockwise or clockwise.

The value of the variable 'x' is calculated by solving equation of the line by using slope value is: x = 3
What is slope of a line?
The slope of a line explain the steepness of the line segment. It is ration of the coordinates of the y-axis and the vertical coordinates of the x-axis. Depending upon the slope value, it is classified as whether lines are parallel or perpendicular.
According to the question, the given parameters for the line segment is as written below:
Slope of a line = (-4) and the coordinate points = (-1, 7)(x,-9): (x1 = -1; y1 = 7)
Now, by using standard equation for the line segment: y = mx + c
where, 'm' is the slope; c is the y-intercept; (x, y) are coordinates
Substituting given values that is slope and y-intercept in the standard equation, we get:
y = mx + c
⇒ 7 = (-4)(-1) + c
⇒ c = 7 - 4 = 3
Therefore, the value of the y-intercept is: c = (3)
Equation of the line by substituting the value of the y-intercept as well as slope value in another equation whose coordinates are (x, -9):
-9 = (-4)x + (3) ⇒ -12 = -4x ⇒ x =3
Hence, the value of the variable 'x' is calculated by solving equation of the line by using slope value is: x = 3

How to compare expressions with indices?
Expressions with indices are of three types:
(1) when bases are equal and powers are different;
(2) when powers are equal but bases are different;
(3) when both powers and bases are unequal.
To solve an expression of type (1), we compare the powers for the given expressions only to determine the greater number efficiently, no heed needs to be given to the base.
To solve an expression of type (2), we compare the bases for the given expressions only to determine the greater number efficiently, no heed needs to be given to the powers.
To solve an expression of type (3), we reduce the power of an expression until it matches the other, so that for comparison only bases are to be taken into consideration without any heed to powers.
Given the expressions are 29², 3 and 64
The given expressions can be re-written as: 29², (√3)² and 8².
On comparing the expressions with the above literature, they match type (2), thus following the assertions we should compare the bases only to find the greatest number.

The method adopted to name the angle below is the three points of the angle.
Therefore, using the three points, the ∠1 can be named as follows:
∠1 = ∠ABC
The middle point is usually the vertex.

Is the ordered pair a solution of the equation? 4x+5y=-1; (1,-1) And 2x-3y=7; (8,-3)
Answers
The given equations are:
4x + 5y = - 1
2x - 3y = 7
For the ordered pairs to be a solution of the equation, the equation must be true when the points are substituted into the equation. That is, the right hand side must equal the left hand side.
For 4x + 5y = -1
To test if (1, -1) is a solution, substitute x = 1, and y = -1 into the equation.
4(1) + 5(-1) = -1
4 - 5 = -1 (True)
Therefore, (1, -1) is a solution for the equation 4x + 5y = -1
For 2x - 3y = 7
To test if (8, -3) is a solution, substitute x = 8, and y = -3 into the equation
2(8) - 3(-3) = 7
16 + 9 = 7 ( False)
Therefore, (8, -3) is not a solution for 2x - 3y = 7
